Important Notice
Equipment used as a primary source for heating or cooling is an integral part of the building in
which it is installed. Proper application is essential for satisfactory performance over a wide
range of operating conditions. It is strongly recommended that a professional engineer
determine proper application.
If this unit is a replacement unit, its specifications and performance may differ from those of
the unit it is replacing. For that reason, we again strongly recommend that a professional
engineer determine proper application. See page 42.

Introduction
This manual is designed to provide product, performance
and application information to our customers and their
architects and engineers for use in selection and design of a
zonal comfort control system utilizing GE Zoneline®
Packaged Terminal Air Conditioners (PTAC) and
Packaged Terminal Heat Pumps (PTHP). GE Zoneline®
PTACs and PTHPs are self-contained units designed for
through-the-wall installations in hotels, motels, apartments,
hospitals, nursing homes and add-on rooms.
Zoneline models provide individual room or zone control in
both cooling and heating operation. There is a model for
practically every application, ranging in cooling capacities
from 7,000 to 15,000 BTUH and heating capacities from
6,400 to 14,500 BTUH in heat pump operation. A choice of
electric resistance heat is available ranging from 2.55 KW to
5.0 KW on 230 volt units and from 1.7 KW to 5.0 KW on 265
volt units.
The Zoneline offers a two tier lineup; the Deluxe Line - the
2200 Series with electric resistance heat, the Dry Air 25
Models with enhanced dehumidification for hot and humid
climates and the 3200 Series heat pump; the Premium Line 5200 Series heat pump.
The Deluxe Line units use standard microprocessor controls
with a two fan motor design. Zoneline 2200 Series
(including the Dry Air 25 Models) Packaged Terminal Air
Conditioners and 3200 Series Packaged Terminal Heat
Pumps offer as standard many of the features found on
competitive units only as added cost options. Features such
as Freeze SentinelTM, Central Desk Control compatibility*,
Low Voltage Remote Thermostat Control compatibility*,
compressor restart protection, random restart after power
failure, mechanical temperature limiting, are standard on
the Deluxe Line. The Deluxe Line also provides some
features not found, even as options, on some competitive
units. Features such as Indoor Coil Frost Control to enable
the unit to operate in the cooling mode under low outdoor
ambient conditions, and a two-stage thermostat on the 3200
Series Heat Pump unit helps maintain a comfortable room
for the occupant while saving energy for the property owner.
The Deluxe Line units also offer cooling with electric heat
and heat pump efficiencies that make them an outstanding
value; Deluxe represented by low operating cost - Deluxe
represented by the standard features - and Deluxe
represented by the competitive initial cost.
The Premium Line units are highly featured micro-processor
controlled and have separate indoor and outdoor fan
motors. The 5200 Series Packaged Terminal Heat Pumps
offer as standard all the features found on the Deluxe Line
units - Freeze SentinelTM, Central Desk Control
compatibility*, Low Voltage Remote Thermostat Control
compatibility*, and Indoor Coil Frost Control - plus the
added features made possible through the use of electronic
controls; features such as automatic fan speed control,
staged heating, electronic temperature limiting, high
ambient heat pump operation, and unit diagnostics. The
5200 Series Heat Pump units also have an exclusive feature
in PTHP units - Selectable Full Time or On Demand
Simultaneous Operation of Heat Pump and Supplemental
Resistance Heat - which provides the most advanced heat
pump operation to assure room occupant comfort while
providing the energy savings of a heat pump. The active
demand reverse cycle defrost system is designed to melt
accumulated frost on the outdoor coil and allow the unit to
resume cost efficient heat pump operation.

Chassis Features and Benefits
• Consistent Physical Dimension
Fits all existing GE Zoneline wall cases (see page 21)
The GE Zoneline was first introduced into the marketplace
in 1961. Since that time, efficiencies and features have been
greatly improved. In spite of these improvements, GE
recognizes that some features should stay the same. That’s
why any recently-manufactured Zoneline chassis can be
installed in any Zoneline wall case, regardless of age. The
original Zoneline wall case was 42" wide by 16" high, the
same dimension of the wall case today, enabling a new
Zoneline to be installed in an existing 42" by 16" wall case
without the need for extensive modifications. Note: Existing
outdoor grille may need to be replaced or modified. (see
page 41)
• Controls Conveniently Located, Easy to
Operate
Reduces uncertainty of operation for room occupant
(see page 8)
Zoneline controls are mounted on the top of the unit,
angled for better visibility and access. The controls are
under a door for appearance enhancement. The 2200 Series
and the 3200 Series have rotary controls for temperature
and operation selection. The 5200 Series units have Touch
Pad controls. An optional locking control door, RAK8022 is
available.
• Universal Heater - Premium Models
Resistance heat output of unit can be matched to the heating
demands of the particular area (see pages 38, 39 and 53)
Often, the choice of a Zoneline heater is influenced by the
location of the room it is intended to heat. For instance, the
end room in a wing or the corner rooms on top floors will
have a higher heat loss than interior rooms having only one
wall exposed to the outdoors. These higher heating
demands are often compromised for the sake of equipment
consistency. In many instances, all rooms are sized higher to
accommodate the minority of the rooms having the higher
heat loads. Naturally, such sizing policies result in increased
total connected current load, and quite often, higher overall
energy costs.
In response to this customer need, each Premium Model is
equipped with three built-in heaters and, when connected
with the proper Universal Power Connection Kit (UPC), can
be closely matched to the heating requirements and circuit
ampacity of a specific room. In addition, this feature allows
maintenance personnel to interchange units in rooms
having different heating requirements.
• Discreet Heater - Deluxe Models
Resistance heat output of unit can be matched to the heating
demands of the particular area (see pages 38, 39 and 53)
Deluxe Models offer cost-conscious customers factoryinstalled discreet heaters. The ninth character in the Deluxe
Line model number represents the specific wattage of the
heater. A Deluxe Model chassis may be ordered with a
custom resistance heater in any one of the following
KW ratings:
230/208 Volts: 2.55/2.09 KW; 3.45/2.82 KW;
5.00*/4.09 KW

• Reversible Discharge Louver
Enables discharge air flow to be changed to maximize air
distribution and comfort (see page 42)
Reversible louver section on all units.
The discharge louver section comes from the factory set to
exhaust air into the room at an angle of 50° off vertical. The
louver section may be reversed to provide a discharge angle
of 40° off vertical with the simple removal of seven screws,
rotating the louver section end to end, and reinserting the
screws. The screws are located on the inside of the room
cabinet.
• Fan Cycle Switch
Allows indoor fan to be set to run continuously or cycle on and off
with compressor and heater
Setting the fan to cycle off and on with the compressor or
heater results in some energy savings when the fan is not
operating. The amount of energy savings will vary
depending upon many factors.
2200 & 3200 Series: The room cabinet must be removed to
gain access to the fan cycle switch. The switch is set in the
DOWN/OFF position at the factory to provide continuous
fan operation in the cool and heat modes. Leaving the
switch in the continuous setting allows circulation of room
air and will result in a more uniform temperature
throughout the room.
The fan switch on the Deluxe Models is located on the
Auxiliary Control Panel. It is switch number two. Setting the
switch in the UP/ON position will cause the fan to cycle on
and off with the compressor or resistance heater. In humid
climates, operating the unit in “FAN CYCLE” may result in
better dehumidification.
5200 Premium Model: The fan cycle switch is located
behind the room cabinet. The switch is set in the DOWN/
OFF position at the factory to provide continuous indoor fan
operation in the cool and heat modes. Leaving the switch in
the DOWN/OFF setting allows continuous circulation of
room air and will result in a more uniform temperature
throughout the room. In humid climates, operating the unit
in “FAN CYCLE” may result in better dehumidification.
The fan switch on the Premium Models is located on the
Auxiliary Control Panel. It is switch number nine. Setting
the switch in the UP/ON position will cause the fan to cycle
on and off with the compressor or resistance heater.
*NOTE: 5.0 KW heaters not available on 7,100 BTUH units.
Chassis Features and Benefits
• Automatic Frost Control
Permits unit to be operated in cooling mode with low outdoor
temperatures
Occasionally, cool outdoor temperatures and high indoor
humidity conditions will cause frost to form on an air
conditioner’s indoor coil. When this occurs, the excessive
frost restricts air flow and decreases cooling performance.
GE Zoneline’s Automatic Frost Control detects when frost is
forming and shuts off the compressor to prevent component
damage. The
unit restarts
automatically
when the frost
has melted. This
feature enables a
room occupant to
select cooling in
spite of low outdoor
temperatures.
• Weather Protected Electrical Components
Extends life of electrical components
Outdoor conditions may shorten the life expectancy of
electrical components such as capacitors and relays. To the
extent possible, all electrical components are located on the
indoor side of the weather barrier (the sheet metal
component separating the indoor side and the outdoor side
of the unit) to protect them from the outdoor elements.
• Corrosion Treatment (Optional)
Helps extend the life of the unit in corrosive environments
An air conditioner installed close to a seacoast or highly
corrosive industrial environment, where acids or salts are in
the atmosphere, will not have the life expectancy of a unit
installed elsewhere. To help extend the life of a Zoneline
installed in these areas, steps are taken to make the unit less
susceptible to corrosion. For example, selection of noncorroding materials, a process of protecting metal parts by
galvanizing and an electro-deposited paint system, all help
retard corrosion. In addition, the aluminum fins on the
outdoor coil are specially treated to extend their
operating life. (Standard on Dry Air 25 Models)
All GE Zonelines can be ordered corrosion treated except
3200 Series Heat Pump units with Internal Condensate
Removal (ICR) System, 265V 2KW Heater Models, 5200
Series Heat Pumps or 2200 & 3200 Series 5KW Heater
Models. Never install a unit with ICR in a seacoast or
corrosive environment. Units installed in corrosive
environments should be examined and cleaned regularly.
• Weather-Resistant “Superseal”
Minimizes air and water infiltration through the unit
When the GE Zoneline is properly installed in an
undistorted GE Zoneline wall case, the air infiltration
through a unit without ICR is a maximum of seven cubic
feet per minute with a 25 mile per hour wind velocity. Units
with ICR have a maximum of ten cubic feet per minute with
the same conditions. The air infiltration test is conducted in
accordance with ASTM E283-91. The ARI specification for
air infiltration for a unit the physical size of the Zoneline is
19 cubic feet per minute.
Unit also meets ASTM E331-86 (Hurricane Test) which
specifies no water can enter through the unit during 15
minute exposure to rainfall at the rate of eight inches per
hour with 63 mile per hour wind velocity.
• Ventilation Control
Hidden controls help prevent unauthorized selection of outdoor
air ventilation - Saves energy
Zoneline chassis are capable of introducing up to 70 CFM of
fresh air into a room. This feature allows maintenance
personnel to “freshen” a room and reduce odors caused by
stale indoor air.
The vent door control is located on the left side of the
chassis behind the room cabinet and out of sight of the
room occupant. Hiding the vent control from the room
occupant ensures that it cannot be changed from the
condition desired by the building management. This is
important because an open vent door introduces
unconditioned air into the room. The additional heat load
causes the unit to operate longer and that translates into
higher operating costs! In warm humid climates the
introduction of outdoor air
may allow excessive
moisture (water vapor) to
enter the room. If the room
air reaches a humidity level
above the “Dew Point” of
the cold discharge air, the
moisture in the room air
will condense into visible
droplets. This condition is
often referred to as “the
unit is producing “Fog, or Fogging.”
• Easy Access Air Filters
Two up-front filters are removable from top of unit without
removing room cabinet
A clean filter is essential for good air conditioner
performance and longer life. A dirty filter reduces air flow
which results in higher energy consumption. GE has made
filter cleaning an easy task! Some packaged terminal air
conditioners or heat pumps which require removal of the
room cabinet or a “blind positioning” of the filter under the
unit, the up-front filters on the GE Zoneline are conveniently
accessed by simply pulling them up from the top of the room
cabinet. This feature reduces maintenance time and helps
keep the units operating in peak condition. Because the
filters are so easy to
remove, it also
increases the
likelihood that
cleaning will occur
on schedule.

Chassis Features and Benefits
• Permanently Lubricated Fan Motors /
Indoor and Outdoor Air Movers
Designed for low maintenance and optimum value, efficiency, and
performance
Zoneline units have permanently lubricated fan motors. Fan
motors that require oiling on a periodic basis generate an
additional maintenance cost for removing, oiling, and
reinstalling the units in the wall case. The Permanent Split
Capacitor (PSC) motors used in Zonelines are permanently
lubricated and totally closed to prevent dirt and foreign
material from entering the motor and shortening its life.
2200 and 3200 Series units use squirrel cage indoor blower
and propeller type outdoor fan. The Zoneline 2200 Series
Packaged Terminal Air Conditioner (PTAC) and the
Zoneline 3200 Series Packaged Terminal Heat Pump
(PTHP) use two fan motors to operate the indoor blower
and the outdoor fan. A squirrel cage blower on the indoor
side combined with 2 discharge ports provide balanced
temperature air flow and quiet operation. The outdoor fan
is a molded polymer propeller type fan. The outdoor fan
motor does not operate in FAN ONLY or in resistance heat
operation on 2200 series.
5200 Series units employ a cross-flow indoor blower and
propeller outdoor fan. The Zoneline 5200 Series PTHP has
two fan motors. A quiet, efficient, tangential cross-flow
blower is driven by the indoor fan motor. The outdoor fan is
a molded polymer propeller type fan driven by a separate
motor. The outdoor fan motor does not operate in FAN
ONLY.
• Rotary Compressor
Fewer moving parts for quiet, dependable service
GE introduced the use of rotary compressors in their air
conditioners in 1957. Today, rotary compressors are the
quiet and efficient compressor choice for Packaged
Terminal Air Conditioners and Heat Pumps.
• Control Devices
Designed to maximize value and room comfort
All Zonelines have electronic thermostats. Electronic
thermostats utilize a thermistor to sense room temperature.
A thermistor is a resistor that changes value (resistance)
with a change in temperature. The resistance changes
rapidly and predictably with temperature. Interfaced with a
microprocessor in the Zoneline 2200, 3200 and 5200 series
units, the thermistor can sense temperature changes as small
as 0.2°F. in staged heating and less than 1.0°F. in the
heating and cooling modes.
12
• Freeze SentinelTM
Automatically turns on resistance heaters to help prevent damage
from freezing temperatures
Freeze SentinelTM is standard on the Zoneline. The
temperature in unoccupied rooms may fall below freezing
during extremely cold weather. In these circumstances,
Freeze SentinelTM automatically provides heat without
relying upon individuals reacting to weather changes. The
Freeze SentinelTM turns the heater and fan on at 41°F. and
off at 46°F. These are temperatures measured at the room
air temperature sensor.
• Compressor Restart Protection
Electronically locks-out compressor operation to allow system
pressure equalization
Compressor Restart Protection is standard on all Zoneline
Units, and prevents the compressor from starting before
sufficient time has elapsed for the internal refrigerant
pressures to equalize. This situation could occur if a room
occupant turns the unit back on too quickly after shutting it
off - or if the thermostat is adjusted immediately after the
compressor has shut off. By locking out the compressor until
the pressures have equalized, the thermostat prevents the
compressor overload from tripping. That in turn, alleviates
any anxious moments for the room occupants while they
wait for the overload to reset.
• High Ambient Heat Pump Operation
Protection
Automatically protects the compressor during heat pump
operation.
High Ambient Heat Pump Protection is standard on the
3200 and 5200 Series Zoneline.
If a heat pump is operated in the HEAT mode when
outdoor temperatures are at a point where heat is not
normally required, the compressor may cycle on the
overload protector. An electronic sensor monitors indoor
coil temperature and terminates outdoor fan operation
when high temperatures are reached and resumes when the
indoor coil temperature drops.
• Emergency Heat Switch
The 3200 and 5200 Series Models are equipped with an
emergency heat switch that overrides the heat pump feature
and energizes the electric resistance heaters. With the
emergency override dip switch set, the heat pump function
is locked out and the unit operates as an electric resistance
heat model. Operating the unit in resistance heat results in
higher utility costs.
Chassis Features and Benefits
• Temperature Limiting
• Compressor Malfunction Indicator
Saves energy by controlling temperature extremes
Temperature limiting restricts the operating range by
preventing the controls from being set to energy wasting
extremes. 2200 and 3200 Series units
have mechanical temperature limiting.
Mechanical temperature limiting
involves positioning screws, located
under the control panel, to restrict the
movement of the temperature control
knob. Each location will reduce the
operating temperature extreme by
about 2.5°F.
Mechanical temperature limiting is
“dependent” type limiting, which means
limiting the lowest cooling temperature
Limiting Screws Shown
will not permit heating selections below
in Factory Setting
that point, and limiting highest heating
temperature will not permit cooling selections above that point.
Mechanical temperature limiting is detectable to the user
since the control knob will not turn to its extreme settings.
5200 Series units with highly featured microprocessor
controls have electronic temperature limiting. The
temperature is limited electronically. The display is limited
to the temperature that the unit can attain. If the
temperature limits have not been programmed, the full
range from 60°F to 85°F can be changed by the user. It also
allows the heating and cooling temperature limits to be set
independently.
Temperature limiting can reduce energy costs by limiting
the lowest cooling temperature and the highest heating
temperature. Electronic Temperature Limiting is achieved
by setting the first six small vertical dip switches in a strip of
14 mounted on the auxiliary control circuit board. The first
three (1 thru 3) are used to select cooling range limits and
the next three (4 thru 6) are used to select heating range
limits.
Service indicator on control panel signals a possible compressor
problem
The Service Indicator is standard on the Zoneline 5200
Series. Should the compressor fail to start after four
attempts, with a three-minute pause between each attempt,
the temperature display will blink to alert the user or the
maintenance staff that the unit needs service. The 5200
Series heat pump will continue to provide heat for the room
with the electric resistance heaters. However, the unit should
be serviced as soon as possible so it may be returned to
economical heat pump operation.

• Auto Fan Speed Control
Automatically selects fan speed necessary for better comfort and
quieter operation
Auto Fan Speed Control is standard on Zoneline 5200 Series.
The units have three fan speed selections - HIGH, LOW and
AUTO
changed by
pressing the
FAN touch
control. When
the AUTO
setting is
selected, the
indoor crossflow blower
and the
Zoneline 5200 Control Panel
outdoor fan
automatically switch to LOW fan speed when the room
temperature is within 1.8°F. of the selected setting. This
feature reduces operating sound level in both the cooling
and heating modes by changing the fan speed to its lowest
operating level.
If the unit is connected to a remote thermostat, Auto Fan
Speed Control is not functional and, if the fan speed is set at
AUTO, the unit will operate in HIGH fan speed. However,
LOW fan speed may be selected by changing setting of dip
switch B (11th from the left) on auxiliary control panel to
the UP/ON position.

• Random Restart
Prevents extreme amperage draw on main circuit after power
failure
Automatic Random Restart is standard on all Zoneline units.
When power is restored after an outage, several compressors
starting simultaneously can cause a power drain. The
Random Restart feature prevents all units from restarting at
the same time. Each unit will restart in a period of three
minutes and three seconds to three minutes and twenty
seconds after the power is restored to the units. The circuit
design adds a random variance to prevent all of the units
from restarting at precisely the same time, and allows time
for the internal pressure of the refrigerant system to equalize
so the compressor will start and not trip the overload.
13
Chassis Features and Benefits
• Unit Diagnostics
• Auxiliary Controls
Switch on auxiliary control panel cycles unit’s components to help
detect malfunction
Unit Diagnostics is standard on the Zoneline 5200 Series.
When the Unit Diagnosis switch, located on the auxiliary
control panel, is turned to the “ON/UP” position, the unit
cycles through the operation of various components. The
operation of the main heater, supplemental heater, indoor
fan motor (both high and low speeds), and the compressor
are checked.
The reversing valve is also cycled through the cooling and
heating modes. The Unit Diagnostics feature helps a
servicer identify a malfunctioning component thus reducing
service call time. During the Diagnostic Cycle a “d” will be
displayed in the temperature display.
The switches on the Zoneline models can be set to provide
operational control to the unit that is not available to the
tenant of the room. It is the owners responsibility to position
these switches to provide the unit operation they desire.
• Quick Heat Recovery (5200 and 3200 Series)
Provides faster room comfort conditions in heating operation
As the name implies, Quick Heat Recovery activates
whenever the heating selection has been initialized. This
feature provides electric resistance heat whenever the unit is
turned on in a heating mode or switched from any other
mode to heating. Its purpose is to quickly bring a room to
the desired temperature by using electric resistance heaters.
This feature minimizes any concerns a room occupant
might raise about the discharge air temperature of a heat
pump and the time it might take to bring the room up to
temperature. Quick Heat Recovery is functional when
connected to a Central Desk Control system.
• Electric Resistance Heat Lock-Out
(5200 Series Only)
Saves energy during milder temperature conditions
The electric resistance heaters are disabled on the 5200
Series whenever the outdoor temperature is above 46°F. This
feature decreases operational costs by automatically
maintaining energy-efficient heat pump operation during
conducive weather conditions. However, The Quick Heat
Recovery Feature (described above) is still operational.
• Load Shedding Option (RAKOIM required)
Provides installation flexibility
Load shedding may be accomplished on any Zoneline
connected to an Energy Management Control System.
Premium Models: The Load Shedding dip switch (switch
“C” (12th from the left), located on the auxiliary control
panel) must be set in the ON/UP position. Deluxe Models:
Load Shedding may also be achieved by setting switch (5th
from the left), located on the auxiliary control panel) to the
ON/UP position.
Load Shedding allows building management to gain control
of the Zoneline’s compressor and heater without affecting
fan operation. Under these circumstances, the fan will
operate whenever the Zoneline’s thermostat closes. Normal
operation is restored when the Energy Management Control
System relinquishes control.

• 2200 Series Enhanced Dehumidification
The Newest Innovation from GE...the Dry Air 25
The Dry Air 25 Models center around GE’s exclusive use of
the patented Dinh® Dehumidifier Heat Pipe from Heat Pipe
Technology, Inc. This innovative NASA spin-off technology
enables the Dry Air 25 to remove 25% more moisture from
the air than other packaged terminal air conditioners.
The Dry Air 25 system, Heat Pipe, is a hermetically sealed
heat transfer surface that is saddle-bagged around the
indoor coil (evaporator) of the Zoneline. This coil
arrangement will transfer heat from one coil to another
without power consumption. This assembly uses R-22 as the
refrigerant and is isolated from the regular Zoneline
refrigerant circuit.
As warm humid air is pulled through the pre-cool section of
the Heat Pipe, the heat removed from the air is absorbed by
the refrigerant, causing the refrigerant to boil. As the precooled air passes through the Zoneline evaporator, the air is
further cooled (colder than it would be normally), removing
25% more moisture than other packaged terminal units.
As the cold air passes through the re-heat section of the Heat
Pipe, the refrigerant condenses and the liquid flows back to
the pre-cool section to be re-heated again. The air
discharged into the room by this process is much drier,
creating a more comfortable room condition.
The Dry Air 25 is perfect for high humidity climates.
Available on 7000, 9000 and 12000 BTU models.
Heat Pumps and Energy Savings
• GE Zoneline Heat Pumps are designed to provide cost
efficient heat pump operation while monitoring room
conditions to maintain comfort.
The units employ a logic system monitoring both outdoor
and indoor temperatures to determine the heat source, thus
increasing energy savings by operating longer in the heat
pump mode.
Heat pumps save energy and cost less to operate than units
with electric resistance heaters as the only heat source. Just
as the EER of an air conditioner is an indication of the
efficiency of the unit, COP (Coefficient of Performance) is
the indication of the efficiency of the heat pump. This
relative efficiency of a heat pump compares the unit to
electric resistance heat. If a unit has a COP of 3.0, it means
the unit will produce three times as much heat at rating
conditions for the same electrical input wattage as an
electric resistance heater.
The compressor is used in heat pump operation just as in
air conditioning operation. In heat pump operation, the hot
refrigerant gas is directed to the indoor coil rather than to
the outdoor coil. Room air that circulates over the indoor
coil gains heat from the coil rather than losing heat to the
coil as during cooling operation.
As the outdoor temperature falls, the heat pump is able to
extract less heat from the outdoor air to raise the
temperature of the indoor air. For this reason all packaged
terminal heat pumps also have electric resistance heaters as
backup to heat pump operation. At some point the heat
pump is unable to provide sufficient heat to adequately
warm the room. Many Packaged Terminal Heat Pumps
cease heat pump operation and change to more expensive
resistance heat at some pre-determined outdoor
temperature to compensate for the inability of the heat
pump to maintain room temperature. This point, called the
“switchover point”, is usually at an outdoor temperature
where savings from heat pump operation may still be
realized, if the unit is designed to maintain room comfort at
the lower outdoor temperatures.
Balance Point
An important consideration of the selection of a heat pump
unit is the “balance point” of the installation. Virtually every
room is unique - with different insulation - different sizes and
types of windows - different types of construction - different
directional exposures. All of these variables, as well as
geographical location, must be considered in order to
determine the balance point, the point at which the heat
pump is unable to produce enough heat to compensate for
the heat loss of the room or area being heated. For these
reasons a consulting engineer should be engaged to
calculate the heat loss and specify the heat pump unit
required.
GE offers two series of Heat Pump units - the 3200 Series
with Standard Microprocessor controls and the 5200 Series
with Highly Featured microprocessor controls - and both
Series utilize multi-stage thermostats to react to the indoor
temperature as well as the outdoor temperature in
determining the heat source to provide comfortable room
conditions and energy savings. This determination of the
heat source based on the indoor temperature helps provide a
more comfortable room.
• Heat Pump Operation — Zoneline 3200 Series
Switchover to resistance heat is determined by indoor temperature
differential and outdoor coil temperature
The Zoneline 3200 Series heat pumps are Standard
Microprocessor controlled units. A solid state thermostat
control is used to measure the room temperature and
compare it to the temperature selected with the “TEMP”
control knob. A temperature sensor is in contact with the
outdoor coil to monitor the outdoor coil temperature
during heat pump operation.
The switchover point of the 3200 Series heat pump is
determined by the outdoor coil temperature or the indoor
air temperature. When the outdoor coil temperature is
above 9°F. (which corresponds to approximately 25°F.
outdoor air temperature), the unit attempts to provide
sufficient heat through heat pump operation to satisfy the
selected temperature setting.
A two-stage thermostat monitors the indoor room
temperature and determines if the heat pump output is
adequate to maintain comfort conditions. As long as the
heat pump output maintains the room temperature within
2.7°F of the set point, the unit will operate in the heat pump
mode. If the room temperature continues to decline with
the heat pump operating, heat pump operation will
terminate and the unit will switch over to electric resistance
heat to warm the room. This heat source logic allows the
heat pump to operate to lower outdoor temperatures,
increasing the savings from heat pump operation, while
providing the ability to use resistance heat only when
necessary. The heat pump and the electric resistance heaters
never operate simultaneously on the Zoneline 3200 Series
Units.
Heat pump defrost - 3200 Series
If the outdoor coil drops below 9°F. (which corresponds to
approximately 25°F. outdoor air temperature), the unit
employs a passive defrost system. A “passive defrost system”
prevents heat pump operation until outdoor temperatures
rise sufficiently to enable economical heat pump operation
to resume. During the defrost mode, the indoor temperature
is maintained by the electric resistance heaters. The defrost
cycle terminates when the outdoor coil temperature rises
above 36°F., at which point the two-stage thermostat will
allow the unit to return to economical heat pump operation.
Heat pump condensate
See page 32 for information on heat pump condensate. The
Zoneline 3200 Series heat pumps may be ordered with a
factory installed Internal Condensate Removal (ICR) system
to minimize the amount of condensate water draining from
the unit during heat pump operation.

Heat Pumps and Energy Savings
• Heat Pump Operation — Zoneline 5200 Series
Heat sources: Heat pump, heat pump and simultaneous electric
resistance heat, or electric resistance heat
The Zoneline 5200 Series heat pumps employ a highly
featured microprocessor control system interfaced with
thermistors to accurately measure indoor air temperature,
outdoor air temperature, indoor coil temperature, and
outdoor coil temperature. This system allows the
microprocessor to precisely and predictably react to
changing conditions in order to provide a very advanced
Packaged Terminal Heat Pump operating system.
The Zoneline 5200 series is designed to help insure a
comfortable room. When “HEAT” is selected, the unit will
determine if the room air is warm enough to satisfy the
thermostat setting. If the temperature at the unit sensor is
below the desired temperature, the electric resistance heater
will be utilized to warm the room to the point where the
thermostat is satisfied. This feature is designed to allow the
temperature of an unoccupied room to be maintained at an
energy saving level without inconveniencing the room
occupant. Once the thermostat has been satisfied, the
resistance heater will turn off and the heat pump will
operate as shown in Zoneline 5200 Series Heat Source Logic
chart when the thermostat calls for heat again. The unit will
operate in this manner even if connected to a Central Desk
Control.

0.8 KW @ 208 V; 1.7 KW @ 265 V
The “Temperature Boost” option, selected by a hidden dip
switch #8, utilizes the supplemental simultaneous heater
with heat pump operation when the outdoor temperature is
below 46°F. regardless of the indoor air temperature. The
chart above indicates the heat source of the Zoneline 5200
series heat pump under various indoor and outdoor
conditions. The unit is designed to provide heat pump
savings without sacrificing room comfort.
The Quick Heat Recovery feature is not affected by the
Zoneline 5200 Series Heat Source Logic shown in the chart
above. For more information about the Quick Heat
Recovery Feature, see page 14. The full heat output of the
resistance heater is dependent upon circuit amperage and
the power connection kit used. See pages 38 and 39 for
information on the power connection kits and available
heater capacities.
Heat pump defrost - 5200 Series
The Zoneline 5200 Series has a reverse cycle demand defrost
system to extend heat pump operation and increase savings
from the extended operation. The microprocessor
16
determines the need for defrosting by criteria based on
continuous compressor running time, outdoor air
temperature, outdoor coil temperature, and the rate of
temperature change of the outdoor coil. When defrosting is
required, the unit reverses the flow of refrigerant to direct the
hot gas into the outdoor coil to melt the frost build-up.
Before and after actual reverse cycle defrosting, the unit shuts
off the compressor to allow the refrigerant pressures to
equalize throughout the system. This eliminates the
possibility of a loud reversing noise. During these periods of
pressure equalization, the full resistance heat capacity of the
unit is activated to help insure room comfort conditions
during the defrost cycle. The defrost cycle termination
requires a minimum of 2 minutes and a maximum of 9
minutes or an outdoor coil temperature of 68°F.
Heat pump condensate See page 32 for information on heat
pump condensate. The Zoneline 5200 Series heat pump may
be ordered with a factory installed Internal Condensate
Removal (ICR) system to minimize the amount of
condensate water draining from the unit during heat pump
operation.
Optional Interface Module —
RAKOIM
The RAKOIM is required if a unit is to be installed with a
Central Desk Control or Remote Thermostat.
The RAKOIM is installed under the control box. There are
channels to contain the RAKOIM and screws are provided to
secure it in place. There is a short wire harness on the
RAKOIM that is plugged into the mating receptacle on the
front of the control box just below the dip switches. There are
screw terminals on the front of the RAKOIM for field wiring.
Follow the instructions included with the RAKOIM when

3200 and 5200 Series (Thermostat RAK147)
Six (6) conductors are required.
The two terminals (A and B) are for Central Desk Control.
Central Desk Control Optional Interface Module (RAKOIM) is
required
Some installations may want to govern the ability of the unit
to operate from a control device remote to the unit or even
remote to the room in which the unit is located. The general
term given to systems such as this is Central Desk Control.
The most common installation of this type of system is a
switch mounted at the registration desk and, upon guest
check-in, a button is pushed or a switch is moved to allow
the air conditioner to operate. Likewise, when the guest
checks out the device is put into the “OFF” position so the
unit will not operate while the room is vacant. It is not
necessary that the controlling device be located at a central
desk to employ a device that will control the unit operation.
For instance, in some resort areas devices are connected to
sliding glass doors and opening the door causes a contact to
close, signalling the air conditioner to turn off. This
prevents energy being wasted by operating the air
conditioner when warm humid air is entering the room.
Some systems operate by motion sensors or heat sensing
detectors mounted in the room. These types of systems
determine occupant presence in the room and allow the
unit to operate; if no one is in the room the device signals
the air conditioner to turn off.
Zoneline models offer Load Shedding capabilities on units
connected to Central Desk Control Systems. For more
information on the Models’ Load Shedding Feature, see
page 14.
There are a wide variety of devices available, each with its
own benefits and constraints. While GE does not offer
components that are external to the unit for a Central Desk
Control (CDC) system, GE Zonelines are compatible with
most CDC and Energy Management systems. No external
power source is required to operate this system. The unit
provides a 24 volts DC circuit that powers the Central Desk
Control system.
All Zoneline 2200, 3200, and 5200 Series units can have the
Optional Interface Module (RAKOIM) field installed to
provide a CDC interface that permits the unit to be
connected to most of the energy management systems on the
market. The devices connected to the Zoneline units require
no power supply or transformer external to the unit.
See page 16 RAKOIM for field wiring.
Important CDC Comments (all series applicable)
1) When the switching device closes the circuit of the
CDC conductors, the unit operation stops.
2) Do not use a common buss (at the unit or at the switch
panel) in the wiring. Both wires comprising the circuit
must connect to the unit’s (RAKOIM) and to the
controlling switch. Running one wire from one unit
to another unit - “common bussing” - may damage
internal components or cause erratic operation of
the system.
3) A 24 volt transformer is contained within the
Zoneline. No external voltage should be applied to
the unit through the CDC terminals. (Voltage on the
CDC conductors is 24 volts DC.)
4) Recommended wire size must be followed as a
minimum requirement.

Freeze SentinelTM remains operational when the unit is
connected to a CDC system. Even if the unit is turned “OFF”
at the central location, if the sensor at the unit detects the
low temperature, the electric resistance heaters and the fan
will automatically turn on.
Connecting the Zoneline to a CDC system does not eliminate
the ability to connect the unit to a remote thermostat. Once
the circuit is “opened”, and control of the unit removed
from the CDC system, the selected controls - either the unit
mounted control or the remote thermostat - govern the
operation of the unit.

unit mounted high in the wall, or over a
transom, for instance, where the unit
mounted controls are inaccessible, can
be connected to a wall mounted
thermostat. The unit is connected to the
thermostat by low voltage wiring which
permits the operation of the unit to be
selected and the temperature to be
sensed at the thermostat. Other
installations may use remote thermostat
control for design or performance
enhancement.

thermostat designed for use
RAK147A1
with heat pump systems. A
thermostat, model RAK147, is available from GE for use
with these units. The control voltage on the remote control
conductors is 24 volts DC. This DC voltage may not be
compatible with some solid state remote control
thermostats.
The 3200 and 5200 Series units use the Optional Interface
Module (RAKOIM), purchased separately. The wiring
connections from the thermostat are made to the color
coded conductors on the socket wire kits. To ensure proper
operation, be sure no wiring is exposed that may come in
contact with the chassis. (A wiring diagram is packaged with
each chassis.)
The 6 remote thermostat conductors for 3200 Series and
5200 Series units are connected to the RAKOIM low voltage
terminal board as shown below. The Class 2 Mode Switch
(dip switch #10 on the auxiliary control board) must be set
to the ON/UP mode to enable remote thermostat control.

Freeze SentinelTM remains operational if the unit is
connected to a remote thermostat. The unit may be
connected to a Central Desk Control (CDC) system and
controlled with a remote thermostat when the CDC system
has the unit in an operational status. (See pages 16 & 17 for
additional information on the CDC system.)
Heat pump operation on a 3200 Series and 5200 Series unit
connected to a remote thermostat is the same as the
operation of the unit without the remote thermostat with
the following exceptions:
The Staged Heating feature (See page 16) on the 5200
Series units does not function with remote thermostat
control. Staged Heating is dependent upon the temperature
sensing ability of the thermistor on the unit, which is
overridden by the remote thermostat. The unit will operate
on heat pump as long as the room temperature is less than
3.6°F. below the thermostat set point and will change to full
resistance heat if the difference is more than 3.6°F. The
temperature differential between heat pump and resistance
heat operation is determined by the remote thermostat
rather than the thermistor on the unit. Even when
connected to a remote thermostat, electric resistance heat is
locked-out when outdoor temperature is above 46°F. (See
Page 16 for the heat pump operating logic of the 5200 Series
units.) Only Electric Heat is available below 46°F. outdoor
temperature if the Temperature Boost switch (dip switch
#8) is set to the ON/UP position.

Remote Thermostat Control
Multiple Units Connected to One Remote
Thermostat (2200 Series)
One remote control thermostat may be used to control
multiple resistance heat Zoneline units, however the units
may not be wired direct. Since each Zoneline unit has an
integral transformer, direct wiring can result in a “bucking”
or “boosting” voltage condition, and is in violation of the
National Electric Code. The diagram below shows the
correct wiring for such an installation through the use of
field supplied isolation relays.

Wall Case
A choice of wall cases is available for the Zoneline.
RAB71 - This
insulated case is
constructed of
heavy gauge
galvanized steel
and finished with
a protective baked
enamel finish for
protection and
RAB71 Wall Case
appearance.
Design of the case
provides for
support of the
chassis and free
draining of any
water entering
the wall case.
A petroleum
microcrystalline
RAB77 Wall Case
wax is applied at
critical points of
fabrication to seal against moisture. The dimensions of the
RAB71 wall case are: 42" wide by 16" high by 13 3/4" deep,
the same dimensions as the original wall case for GE
Zonelines built in 1961.
RAB77 - This non-insulated wall case is molded from
fiberglass-reinforced polyester compound. This SMC (Sheet
Molded Compound) wall case offers outstanding strength,
durability, color retention, water integrity and corrosion
resistance. The dimensions of the RAB77 wall case are: 42
1/8" wide by 16 1/4" high by 13 7/8" deep.
• Both wall cases are of universal design, accepting all
Zoneline chassis of current design as well as all GE
Zoneline chassis produced since 1961.
• Drain holes are provided in the rear of the wall case to
permit excessive cooling condensate water, heat pump
condensate, or precipitation entering the wall case to
drain freely. A drain kit may be connected to the wall case
to control any water draining from the wall case. See pages
33 and 34 for information on RAD10 Drain Kit.
RAK901L - For installations when wall case extends into
room, an RAK901L is an insulation kit that can be used with
the RAB77 or any existing non-insulated wall case to
minimize the possibility of condensation forming on the
indoor side of the case.
Sub-Base
The sub-base is an optional accessory for the Zoneline and is
presented with the wall case information since the decision
to use or not to use a sub-base in the installation is a factor
in the location of the wall opening for the unit. National
Electrical Code® requires that air conditioning units
connected to voltages in excess of 250 volts be “permanently
connected”. There are also some installations where units
connected to voltage sources under 250 volts may also need
to be “permanently connected”. If you are in doubt about
the requirements for a particular installation being
designed, consult Article 440 of the NEC. These
requirements are designed to protect personal safety and
should be strictly followed. Although NEC is cited here as a
reference, all electrical wiring and installations must
conform to any and all local electrical codes and
regulations.
“Permanent Connection” generally means wiring between
the building wiring and the unit must be contained in an
enclosed “chaseway”, where access to the wiring connections
is more restrictive than a normal line cord plugged into a
receptacle. NEC requirements may be met by using flexible
or rigid conduit to contain the wiring between the unit and
a junction box that contains the wiring connections. The
conduit is connected to the unit and to the junction box
with connectors to hold the conduit in place. The junction
box may be located in the floor or the wall of the structure
but only approved connectors may be used outside the unit
or the junction box. The sub-base is UL® listed as a junction
box for permanent connection of a Zoneline.
Using a sub-base in an installation requiring permanent
connection provides a convenient, consistent location for
unit wiring to be connected to building wiring. The use of a
sub-base is not required, but the convenience and the
improved aesthetics it offers makes the use of a sub-base a
viable means of permanent connection.
RAK204U - The RAK204U Series of sub-bases provides a
variety of designs that fit the site needs and are available for
use with Zoneline PTAC/PTHP units. The RAK204U will
most likely be
used for
support of
the wall case
and unit.
The
RAK204U is
the same physically as the other sub-bases except there is no
receptacle installed. Receptacles and wiring can be field
installed and, by using the RAK205CW chaseway and the
RAK4002 junction box, performs the same function as any
of the other sub-base kits by selecting the correct receptacle
and installing it in the interior mounting plate inside the
RAK204U.
208/230 volt receptacles can also be mounted in the center
cover plate for easy access when direct connect wiring is not
required. 265 volt units are to be “Direct Connected” and the
external receptacle (not enclosed in a chaseway) does not
meet this requirement. Knockout for fuseholder
is provided.
RAK204U No receptacle, no wiring, will accept any 15, 20,
30 amp receptacle and wiring. No chaseway is included.
Note: RAK205CW is the chaseway and must be ordered
separately.
RAK204D20 208/230 volt 15/20 amp receptacle. Note: 18
inch #12AWG wires attached to the receptacle. (Receptacle
NEMA6-20 GE4181-2) Chaseway included.

Sub-Base (Cont.)
Chaseway RAK205CW is included with RAK204D20,
RAK204D30, RAK204E15, RAK204E20 and the RAK204E30.
If the chaseway is needed when using the RAK204U, it must
be ordered separately as RAK205CW.
There are separate internal compartments to permit
separation of low voltage (Class 2) connections from line
voltage connections as required by NEC. Conduit containing
building wiring enters the sub-base through knockouts
located in the rear or bottom of the sub-base and is not
accessible when the wall case is installed.
The sub-base attaches to the RAB71 wall case with two clips
(field assembled) that are screwed into pre-drilled holes in
the bottom front flange of the wall case. It attaches to the
RAB77 wall case with clips that fit over molded ribs without
requiring the use of screws into the wall case. See page 31 for
illustration. Since the sub-base extends under the wall case,
clearance from the inner edge of the wall case to the
finished wall must be 2-3/8" or greater. The sub-base has 4
leveling legs and adjustable side channels to enable the area
under the wall case to be enclosed. Clearance from the
bottom edge of the wall case to the finished floor must be
between 3" and 5".
The sub-base may be used as support for the chassis and wall
case in installations where the wall is of insufficient thickness
to provide secure mounting of the wall case.
Wall Case Installation Data
General
Generally, Zonelines are installed 3" to 5" above the floor
(flush to finished floor installation is possible) as near to the
center of the room as possible; underneath a window or a
glass panel is typical. Normal installation of the wall case
allows installation flexibility; from flush with the finished
interior wall to a minimum of 1/4" of the wall case
extending beyond the finished exterior of the building.
Special consideration must be given to installations where
the wall case does not extend a minimum of 1/4" beyond
the finished exterior wall. See pages 28 and 29 for
information on this type of installation. The unit may be
installed high in the wall and these installations usually
require a remote thermostat and are discussed on page 18,
19, 27 and 42.
Regardless of the installation, there are several things to
consider when selecting a location for installing the unit.
For instance, drapery location could interfere with air
discharge, and placement of furniture may have an impact
on the performance of the unit. The following information
is intended to minimize installation problems and assure
you of trouble-free installation.
Refer to page 24 and 25 for required wall opening
dimensions. Minimum recommended interior and exterior
case projection for standard wall thicknesses are shown in
the drawings in this manual. The case may be installed flush
with the finished indoor wall. Special attention must be paid
to room-side case projection when the unit is installed in a
ducted application as shown on page 37, or with a sub base
as shown on page 25.
In walls thicker than 13 1/2" for line cord connected units
and 11 1/8" for sub-base installations, it may be necessary to
install a field fabricated case extension. If you are unable to
locate a local source for case extensions please contact your
salesperson for a possible supplier. Such extension must be
22
carefully flashed and sealed both to the wall case and to the
wall to insure water integrity. This is necessary to insure that
any water entering the wall case, either from operation of
the unit or from other sources, such as rain storms or from
washing the exterior of the building, will drain from the case
without the possibility of capillary action drawing the water
into either the room or the wall cavity. In an installation
where the case is recessed less than 3" from the outside
surface, flashing and sealing may be all the modificaton
necessary. In such an installation, the sides and top of the
wall opening must be waterproof to prevent moisture from
seeping into and damaging the walls. See Pages 28 and 29
for suggested detail.
When the outdoor grille or louver section is mounted to the
building face, causing a space between the outdoor coil and
the louver section, air splitters, aligned with the ends of the
outdoor coil, must be installed between the outdoor coil
inlet and outlet air streams. See page 41 for requirements for
custom louver sections.
The wall case should be level from side to side and front
to back. The condensate disposal system in the unit is
designed to dissipate the condensate water generated
during cooling operation in accordance with ARI
standards and actually uses this water to increase the
efficiency of the unit. A level unit will also insure proper
performance of the Internal Condensate Removal (ICR)
system optional on heat pump units.
For new construction, early planning with the architect is
necessary. Unit location, electrical connection locations, and
wall openings of the proper dimensions are essential to
avoid the necessity of rework, fillers, framing, moving
electrical outlets, and other expensive modifications.
For existing construction it is important that carpentry,
masonry and electrical work be performed by competent,
qualified personnel. Since installations in existing
construction may involve removal of building material from
the structure, locating the wall case must be done correctly.
Window, Curtain and Panel Wall Construction
With this type of construction, provision for support of the
unit, other than by the wall itself, is often required. Such
support may be in the form of wood or metallic material of
the proper thickness to maintain a level case. This
additional support should be located both near the wall and
at the front of the wall case. Sub-base (RAK204U Series)
with four leveling legs provides an excellent support for the
unit in this type of installation. See page 26 for details of this
type of installation.
In existing construction, common practice is to remove a
pane of glass, metal, wood, or other construction material
and build a frame around the wall case. Similar filler panel
material may be installed around the case for appearance
and weather seal.
Masonry Wall Construction
The wall case should be installed during construction and
lintels should be used to support the blocks above the wall
case. The wall case will not support the concrete block. The
installation instructions show how the wall case must be
secured to the masonry and caulked. Do not remove the
cardboard stiffener supplied with the wall case until ready
Masonry Wall Construction (Cont.)
to install the chassis. See page 27 for details of installation in
masonry wall.
For existing masonry construction, wall openings must be
made. This normally involves the removal of concrete blocks
to achieve the proper size opening. Consult the builder,
architect, or owner to determine the necessity for lintels to
support the block above the wall case.
Anchor bolts are normally required to secure the case to the
wall and shims may be required to prevent distortion of the
wall case when securing the wall case to the wall. Field
supplied case angles can be used to position and secure the
wall case to the wall and to cover oversized wall openings.
Wall Case Installation Data
Brick, Frame, Stucco and Shingle Construction
For new construction, the opening for the wall case should
be framed and the wall case inserted into the opening
during construction. Lintels should be used when the
building material is heavy and is not self supporting (such as
brick). The wall case will fit an opening of six courses of
standard brick or five courses of jumbo brick. Wall framing
in this type construction is normally on 16" centers and the
wall case will fit a framed opening spanning three 16" O.C.
2" x 4" stud spaces.
For existing construction the indoor and outdoor wall will
need to be cut out, allowing for clearances of 1/8" on all
sides of the wall case. Work should begin on the inside wall.
Cut the correct dimensions and mark (using drill holes) the
outside wall from each corner of the inside cutout. Studding
that interferes with the opening must be removed and a
suitable frame constructed to secure the wall case and
provide adequate support for case and chassis.
Preparation of the Wall Case for All Types of
Construction
As shipped, the RAB71 or RAB77 is ready for installation.
Do not remove the stiffener from inside the wall case or the
weather closure panel from the outside face of the wall case
until the outdoor grille and chassis are ready to be installed.
Installation of Wall Case in Wall Opening
1. Position the wall case into the wall. The room side edge of
the RAB71 or RAB77 wall case should be at least flush
with the finished wall for line cord installations and
permanent connection installations when no sub-base is
used, and should project into the room at least 2-3/8"
when a sub-base is used. If the minimum exterior
dimensions are not met, refer to page 28 and 29. The
outside edge of the wall case should extend at least 1/4"
beyond the outside wall. This is necessary for proper
caulking, to prevent sealing the drain holes in the rear
flange of the wall case, and to facilitate the installation of
an accessory drain, if used.
The wall case should be level from side to side and front
to back. The condensate disposal system in the unit is
designed to dissipate the condensate water generated
during cooling operation in accordance with ARI
standards and actually uses this water for maximum unit
efficiency. A level unit will also insure proper
performance of the Internal Condensate Removal (ICR)
system optional on heat pump units.
2. The wall case should be secured to the wall at both sides.
Use a minimum of two screws or other fastening device on
each side. See Figure 2 page 24. Mark the wall case on
each side 2" from the bottom and 2" from the top at a
point where basic wall structure is located. Drill wall case
and use fasteners appropriate for wall construction. All
holes for fasteners in the side of the wall case must be at
least 2" up from the bottom of the wall case. Never locate
screws or put other holes in the bottom of the wall case.
The only exception is when an RAD10 drain kit is
installed to connect to an internal drain system. See page
34 for RAD10 Drain Kit information.
If the wall opening is greater than the case dimensions,
spacers must be used on the sides between the wall case
and the wall support structure to prevent distorting the
wall case.
3. Caulk or gasket the entire opening on the outside between
the wall case and exterior wall surface (4 sides) to provide
total water and air seal.
4. Caulk or gasket room-side opening between wall case and
interior wall surface (4 sides). Opening beneath or
around the wall case can allow outdoor air to leak into the
room resulting in increased operating costs and improper
room temperature control.
Care should be taken in location of electrical supply entry
in relationship to wall sleeve to assure access to receptacle
or junction box once unit is installed.
• Refer to page 38 for maximum power cord length.
• Permanent connected units close to finished floor must
allow for conduit clearance.
Case Angles
In some installations such as curtain walls, window walls, or
where the structural material of the wall is insufficient to
support or fasten wall case to, the use of case angles may be
used. Case angles are pieces of steel or other material of
similar structural strength that are formed to a 90° angle,
with holes to fasten the case angle to the wall case and to the
structural component of the wall surrounding the
wall case.
The following describes the procedure when field fabricated
and installed case angles are applied.
1. Position case angles around top and sides of wall case at
the desired location. Position case angles vertically on
each side of wall case to provide a level installation.
2. Mark wall case through holes in case angles. The lowest
hole on the sides of the wall case must be a minimum of
2" above the bottom of the case
3. For RAB71 wall case drill 5/32" diameter holes at
locations marked on wall case in Step 2, and assemble
angles to wall case using #10 x 1/2" self tapping screws.
For RAB77 wall case follow the same procedure except use
a #10 x 1/2" bolt, washer and nut to attach case angles to
case. Install screws or bolts from outside
wall case.
4. Do not drill any holes in bottom of wall case. Do not
distort wall case.
5. Do not use case angles for a lintel.

butting flanges. Use bolts and nuts or oversized
self tapping screws (driven from the wall case to
the extension) to attach the two assemblies. Clean
all drain holes of excess sealant. The assembly
must be free draining.
3. Install flashing, using a quality grade sealant
between the flashing and wall as shown in section
A-A below.
4. Install the wall case/extension assembly following
procedures described for a standard installation.
See diagrams below. The assembly should be
sealed or caulked to the wall around all four sides
both outdoors and indoors.
NOTE: The wall case/extension assembly should
be level in all directions.
EXTENSION
(FIELD
SUPPLIED)
Zoneline units can be installed in walls of greater
depth than the wall case. Where the case recession
is less than 3” and where it is possible to waterproof
the exposed sides and top of the opening, the
suggested procedure is to apply a flashing to the
bottom of the wall case as shown on page 29. Where
waterproofing is questionable or not possible, or for
installations in walls of greater depth, the following
is a suggested application procedure. It involves the
field fabrication of a case extension. Since the wall
case is a water bearing container, the extension
likewise must also be water bearing and the
connection between the two must be watertight. The
case extension must contain splitters to prevent
recirculation of the outdoor air circuit.
1. The case extension is field fabricated. The
entension depth “D” should allow for a minimum
outdoor projection of 1/4”. This allows for room
cabinet clearance to the finished wall and ample
surfaces to apply sealant or caulking for a tight
weather seal between the completed wall case/
extension assembly and the wall opening. It is
recommended that the extension be painted and
corner and lap joints be additionally sealed with a
quality grade sealant.

Condensate Disposal Systems
Cooling Condensate
Air conditioners produce condensate water as a result of
lowering the humidity of the area being conditioned. When
the indoor coil temperature is below the dew point, moisture
in the air condenses into water droplets on the coil. This
water drains to a pan located under the indoor coil and is
routed through the barrier, the sheet metal separating the
indoor and outdoor sides of the unit, to the base pan on the
outdoor side. It is then picked up and dispersed against the
outdoor coil, which is hot when the unit is in the air
conditioning mode. The water is evaporated into the
atmosphere by contact with the hot outdoor coil. This
evaporation process also helps lower the temperature of the
outdoor coil and improves the operating efficiency of the
unit.
Slinger Ring Systems
Packaged Terminal units employ various means of
dispersing the condensate water against the outdoor coil.
One of the most popular, and most effective, means is by the
use of a “slinger ring”. A “slinger ring” is a ring around the
circumference of the outdoor fan. The design of the unit
positions the slinger ring very close to the bottom of the base
pan so water in the base pan is lifted by the rotating ring.
Water picked up by the slinger ring will be dispersed into the
air stream and deposited on the hot outdoor coil where it
evaporates.
All Zoneline Series Packaged Terminal Air Conditioners
and Packaged Terminal Heat Pumps utilize a slinger ring
for cooling condensate disposal.
Certification Test Requirements
ARI requires that all certified Packaged Terminal Air
Conditioners and Packaged Terminal Heat Pumps pass a
cooling condensate disposal test. One stipulation of the ARI
test is that “the test start with condensate collection pan
brimful”. In order to pass the ARI Condensate Disposal Test
the unit must operate continuously for four hours without
condensed water blowing, dripping, or running off the unit
casing during the test or after the unit has been turned off.
Under extremely high outdoor humidity conditions or
extreme operating conditions, such as exceptionally high air
infiltration (a door or window left open while the unit is
running, for instance) it is possible for any air conditioner
to be unable to dissipate all the cooling condensate
generated.
All Zoneline Series Packaged Terminal Air Conditioners
and Packaged Terminal Heat Pumps meet the condensate
disposal requirements of ARI standards 310-90 and 380-90.
Heat Pump Condensate
During the operation of a unit in the heat pump, or “reverse
cycle”, mode the outdoor coil becomes the cold coil and the
indoor coil becomes the hot coil due to reversing the flow of
the refrigerant. When the temperature of the outdoor coil is
below the dew point, condensation will form on the outdoor
coil just as it does on the indoor coil during cooling
operation. Since the dew point is humidity as well as
temperature related, there may be more condensate on days
when the relative humidity is high.
Heat Pump Condensate Disposal
Since the outdoor coil is cold during heat pump operation,
the condensate water cannot be deposited on the outdoor
coil as the water would cause frost to form on the coil. This
frost would block the air flow through the coil and greatly
diminish the ability of the heat pump to extract heat from
32
the outdoor air. Rather than allow this problem to occur
heat pump units must dispose of the condensate in another
manner.
Temperature Activated Drain Valve
The most widely used method of disposing of heat pump
condensate is with a “Temperature Activated Drain Valve”.
This is a device mounted in the base pan of a heat pump
unit with a bellows that expands on temperature rise and
contracts with temperature drop. A shaft with a rubber plug
on the end is connected to the bellows. When the outdoor
temperature remains above a certain temperature, the
bellows is expanded and the plug fits tightly into a hole in
the bottom, or base pan, of the unit. When the plug is
blocking the hole, as it should be during cooling operation,
the condensate water is contained in the base pan. At
temperatures when heating is required, the bellows
contracts, the rubber plug is retracted from the hole and the
heat pump condensate water is allowed to drain into the
wall case. The valve is fully open at 49°F.
Drain Kits
Although the Zoneline units are designed to dissipate all of
the condensate generated during normal cooling operation
there may be times when abnormal operating conditions
cause more condensate than the unit can dissipate. Heat
pumps also generate condensate that the unit may not be
designed to dissipate. For these reasons, if condensate
dripping from the wall case is objectionable, an internal or
external drain system should be installed. See pages 33 and
34 for information covering the drain systems and the
RAD10 kit available to connect to the wall case.
Internal Condensate Removal (ICR) System
GE has developed an Internal Condensate Removal (ICR)
System for Packaged Terminal Heat Pumps. This system has
been offered as an option on Zoneline Packaged Terminal
Heat Pumps since 1982, and thousands of them are in use.
During heat pump operation the ICR system utilizes a small
pump to lift the water from the base pan and pump it into a
collector tray positioned above the indoor coil. The water
drains from the collector tray and drips onto the warm
indoor coil where it is evaporated into the room atmosphere.
If an excess amount of water is pumped to the indoor side, it
is routed back to the outdoor portion of the base pan.
The ICR system has proven to be an effective means of
minimizing the amount of heat pump condensate dripping
from the unit. However, if the restrictions of a particular
installation will allow absolutely no drippage of condensate
water from the wall case, the installation of an internal or
external drain system is recommended.
Units with ICR may not be installed in seacoast or corrosive
environment applications.

the straight tube. Modification must be made to the RAG67 grille if using either the 90° elbow tube or the straight tube
(see installation instructions with the RAG67 grille).
For those installations where water draining from the drain holes is objectionable or where positive drainage is
desired, the RAD10 drain kit is available with either a 90° elbow or a 6” straight tube to be used either to connect to a
field supplied drain line or to allow the water to drip free rather than drain down the surface of the building.
WATER DRAINAGE - Precipitation entering the unit through the outdoor louver may not be removed entirely by the
condensate removal system. The base pan flange is designed to allow excess water, either condensate water or
precipitation, to flow into the wall case and drain through two drain holes in the rear of the wall case. If there is more
water in the wall case than can be drained through these holes it will drain through the three overflow drain holes.
These drain holes must not be blocked when mounting or caulking the wall case.

Ducted Installations
2200 and 3200 Series Zoneline units may be
used in ducted installations.
With a ducted installation it is possible to condition the air
in two areas that have a common wall separating them. A
special adapter mounts on the wall case and a transition
piece directs the air from the unit into the adapter.
Instructions for mounting the adapter to the wall case are
included with the duct adapter. The adapter contains a
grille that allows air from the unit to be discharged into the
primary room and the adapter connects to a duct extension
that allows the air to flow to the adjoining room. Ducting a
unit may allow a single unit to be used rather than a
separate unit in each room, providing a means of reducing
initial equipment cost. The duct may extend a total of 15
feet (with a field fabricated insulated duct extension) in one
direction, either to the right or to the left of the unit. A
baffle in the adapter allows up to 50% of the discharge air to
be delivered to the secondary room.
The installation of the wall case and sub-base, if used, is the
same for units being ducted as for free-standing units. The
duct adapter support bracket overlaps the wall case by 1"
and the bracket and mounting screws add approximately 3/
8" (3/16" on each side) to the width of the wall case. If less
than 1" of the wall case projects into the room it will be
necessary to allow for the additional width in the opening
for the wall case. The duct adapter mounting brackets
should be mounted prior to installing the case in the wall.
Refer to pages 36 and 37 for drawings of ducted
installations.
Prior to the installation of the transition from the room
cabinet to the adapter, it will be necessary to remove the
discharge grille from the room cabinet to permit optimum
air flow into the adapter. Instructions for this modification
are included with the duct adapter.
New Ducted Installations
Components
Duct Adapter RAK6052 - The duct adapter is secured to
each side of
the wall case
and requires
the drilling of
mounting
holes in the
wall case
during
installation. By
securing the
duct adapter
Duct Adapter RAK6052
to the wall
case, the chassis retains the slide-out feature for servicing
after the transition piece is removed.
Duct Extension RAK601 - This kit contains a 44" long
insulated duct, a register mounting collar, and an air supply
register. It can be secured to the duct adapter at either end
of the adapter. This duct may be cut at any dimension and
used in two applications providing the sum of the two duct
lengths necessary do not exceed the 44" length. Even in
single applications the mounting flange must be cut off one
end of the duct to accept the collar and supply register.
Mounting Collar and Supply Register RAK602 These
components
are included in
the Duct
Extension Kit
RAK601. They
may be
ordered
RAK601 Duct Extension,
separately for
Mounting Collar and Register
installations
where two duct extensions are made from one RAK601.
Ducted Application
Considerations
When designing a ducted application some application
considerations to be made include:
1. Do not exceed the 15 foot length maximum for the duct
extension. Field supplied duct extension must be
completely insulated with minimum of 1/2" insulation
2. The duct must be a straight run. Turns or bends in the
duct extension create air pressure drops that the unit is
not designed to overcome.
3. Minimum recommended clearance between the unit and
the adjacent wall is 2".
4. Provisions for return air must be made to allow air
circulation from secondary room. Doors in both
secondary and primary rooms may be undercut or a
return grille may be installed through a common wall.
5. When calculating the heat gain / heat loss take both areas
into consideration.
Replacements of Existing
Ducted Units
Since the design of Zoneline chassis has changed over the
years to provide better performance and appearance, some
of the components used in ducted applications have
changed. Select the proper components from the
information below. The best procedure of determining the
correct kit is to measure duct extension cross section.
Flat Top-Discharge Units
(Zonelines Built Prior to 1988)
Existing Duct Extension Cross Section Measurements:
8-3/8" height x 6-1/2" width
Duct Adapter RAK7012 - This duct adapter will allow the
replacement of a new chassis (AZ22 or AZ32 Series unit)
into an existing ducted application. This adapter will align
properly with the duct extension and will eliminate the need
to modify the wall opening. In order to minimize
replacement costs, some of the components of the old duct
adapter must be removed and used in the new installation.
Consult the Installation Instructions of the RAK7012 before
removing and discarding the old duct adapter.
Slope-Front Discharge Units
(Models With AZC, AZR, AZW, or AZ Prefix)
Existing Duct Extension Cross Section Measurements:
7-3/32" height x 6-1/2" width
Duct Transition RAK7022 - This duct transition will allow
the replacement of a new slope-front discharge Zoneline
chassis (AZ22 or AZ32 Series unit) into a previous design
slope-front ducted installation.
35
36
8. For replacement of previous design units, see page 35.
7. Provisions for return air must be made in order to allow air circulation from secondary
room. Doors in both secondary and primary rooms may be undercut or a return grille
may be installed through common wall.
6. Unit must be installed to provide at least a 1” clearance between side of unit and wall.
5. Filler strip (field supplied) actual width depends upon wall case projection into room.
A flush installation to finished wall (i.e., no filler strip) can be made.
4. Duct extension kit RAK601 contains 44” duct extension, discharge grille mounting collar,
and discharge grille. Duct extension must be cut to required length. Two ducted
installations may be made from one kit if the combined ducted length is less than 44”.
RAK602 kit contains mounting collar, discharge grille and mounting hardware necessary
for second installation.
3. Ducted units may need to be permanently connected. Check local code for specific
electrical installation requirements.
2. RAK601 duct extension may be installed at either end of the RAK6052 duct adapter.
Maximum duct extension length is 15’. Duct extension must be field fabricated for
installations where length of duct exceeds length of RAK601 (44”). Field fabricated duct
extension must be insulated to prevent condensation from forming on exterior. Duct
extension may not contain bends or turns.

Power Connection Kits For
Premium Series (5200)
The Zoneline 5200 series units are connected to the
building power supply by a unique power connection kit. By
utilizing a separate universal power connection (UPC) kit,
each unit is capable of providing various outputs of electric
resistance heat to more closely meet the heating
requirements of the particular room, thereby increasing the
installation flexibility of the particular chassis. This power
connection kit is the only means of supplying power to the
Zoneline chassis and the appropriate kit is determined by
the voltage, the means of electrical connecton - either line
cord connected or permanent connected - and the desired
resistance heat output that may be supported by the branch
circuit.
230/208 Volt Installations
Connections to 208 or 230 volt circuits may be made with a
line cord power connection kit.
Line Cord Kits consist of a self-aligning 9-pin molded
connector that plugs into a mating connector on the
Zoneline chassis and insulated line cord with an electrical
plug on the end. The configuration of the electrical plug
conforms to NEC standards for the circuit amperage and the
postion of the wires in the 9-pin connector determines the
heater wattage and current requirements when it is plugged
into the Zoneline chassis.

Connection is accomplished by ordering the correct
ampacity electrical sub-base to match the Power Cord being
used. See page 21 Sub-Base for description.
There may be special requirements by some sites that rigid
or flexible conduit be used. (Such as the wall case must be
installed flush to finished floor and there is no room for a
sub-base.) In these installations the RAK4002 junction box
will be needed and the Power Cord/Cord Set will be cut and
connected to building wiring inside the RAK4002 junction
box. Conduit will be attached to the RAK4002 and to the
site supplied building/room junction box where the
building wiring enters the room. Wiring will be totally
enclosed by conduit and junction boxes.
Power Connection Kits For
Premium Series (5200)
265 or 277 Volt Installations
Electrical Wiring Information
National Electrical Code (Article 440 section G) requires
permanent connection for installation on circuit in excess of
250 volts.
Permanent Connection Kits are available for 265 volt
installations. The regular kit consists of a self-aligning
9-pin connector that plugs into a mating connector on the
chassis, a length of power cord with the plug cap molded to
the end. There are four 265 volt cord sets so that the desired
heater KW will be achieved when the correct RAK5*** kit is
selected. See chart below for guide. These cord sets will
match the receptacle in the RAK204E Series sub-base. It is
important that care be used in this selection process. This
cord set, when used with the appropriate sub-base with
provided chase way from the junction box to the sub-base, is
considered to be permanently connected.
For those installations that require a method of direct
connection using flexible or rigid conduit, the RAK4002
junction box (provided with chassis) can be used and the
field supplied conduit attached to it. The universal cord set
will be cut off and connections made inside the
junction box.
For all installations feeder, sub-feeder, branch circuit and
electrical protective devices and selection must conform to
the National Electrical Code and to local codes.
Maximum connected load in amperes, including demands
for the electric heater and the fan motor, are shown on page
54. Branch circuit ampacity and electrical protective device
sizing are shown at left. More than one unit per branch
circuit is not recommended; however, when in doubt,
consult the National Electrical Code. All wiring, including
installation of receptacle, must conform to local electrical
regulations and codes.
Replacement of Existing Chassis
230/208 Volt and 265 Volt Units
There have been changes to NEC and improvements and
modifications to the Zoneline chassis and sub-bases since
the unit was first introduced. Some of these changes require
alterations to be made when replacing an older unit with a
new chassis.
Line Cord Connected Units
The plug configuration of new line cord connected units
complies with the current NEC standards. Older
installations may have wall receptacles that conformed to
NEC standards at the time the building was constructed and
may not match the configuration of the plug on the new
line cord. Recommended solution is to change the wall
receptacle to conform to current standard plug
configuration. See chart on page 38 for current receptacle
configuration.

If the existing unit is connected to a sub-base the installation
of the new unit may involve modifying the existing
installation slightly. It is recommended these modifications
be made by a qualified electrician.
If the existing sub-base is the full width of the wall case,
RAK201 sub-base access plate may be ordered and used to
replace the cover on the old sub-base. Field supplied wiring,
conduit and conduit connectors should be used to make
connection between new chassis and the center knockout of
the RAK201. The wiring connections should be made inside
the sub-base and the RAK201 attached to the sub-base with
the 2 screws provided.
If the existing sub-base is not the full width of the wall case
the electrician will have to modify the existing cover plate to
allow field supplied wiring, conduit, and conduit connectors
to be run from the permanent connection kit to the subbase.

Power Connection For Deluxe
Series (2200 & 3200)
The Zoneline 2200 and 3200 series units have discrete
heater wattages. Each unit has a factory installed heater and
must be installed on an electrical circuit with sufficient overcurrent protection to carry the amperage load of the unit.
See specifications on page 52 for model number
nomenclature, heater amperage, and minimum circuit
ampacity for the particular Zoneline model. To determine
maximum connected load for individual model see page 54
and 55.
230/208 Volt Unit Installation - Line Cord Connected Units
Zoneline 2200 and 3200 series units for installation on 230
or 208 volt circuits have a factory installed line cord with a
plug conforming to NEC standards for the circuit amperage.
Graphic representation of the wall receptacles are shown on
page 38. The line cord length is also shown on page 38.
230/208 Volt Unit Installation - Permanent Connected Units
If a permanent, or direct wired, installation of a 230 or 208
volt units is desired, a junction box kit, RAK4002, is available
to allow direct connection when the 208/230 volt chassis is
installed with the appropriate electrical sub-base. When the
cord set is enclosed by the RAK4002 and the sub-base chase
way RAK205CW, the wiring is totally enclosed and the unit is
considered to be permanently connected. (correct ampacity
RAK204 series sub-base required)
If an installation using flexible conduit is desired, the
RAK4002 kit mounts to the chassis to form an enclosed
junction box with a removable front panel for access to the
unit wiring. A 7/8" diameter hole in the bottom of the
enclosure enables field supplied rigid or flexible conduit to
be connected to the kit. A wiring harness of three
conductors and an in-line connector is included with the
RAK4002.
The factory installed line cord must be cut off approximately
8" from where it comes through the barrier, or bulkhead, of
the unit. Strip insulation off 3/4" of each conductor to
expose wire for field connection. These wires are then
connected to the building wiring by field supplied
connectors.
265 or 277 Volt Unit Installation - Permanent Connected
Units
National Electric Code (Article 440 Section G) requires
permanent connection for units connected to power sources
over 250 volts, therefore these units must be permanently
connected (direct wired).
Zoneline 2200 or 3200 series units rated for installation on
265 volt circuits have discrete heater wattages and the
appropriate cord set to match the 265 volt sub-base
receptacle installed in this sub-base. When installed with the
correct sub-base and chaseway the wiring is totally enclosed
and the installation is considered to be permanently
connected.
If an installation using flexible conduit is desired, the 7/8"
diameter hole in the bottom of the RAK4002 junction box
enables field supplied rigid or flexible conduit to be
connected to the unit. A knockout is provided in the
junction box for the installation of a field supplied cartridge
type fuse, if required. A wiring harness of three conductors
and an in-line connector is included with the RAK4002.
This wiring harness can be ordered separately as
RAK4002CW.
When direct connecting the unit, connections to the
40
building wiring should be made in the junction box with
field supplied connectors.
All wiring must conform to local electrical regulations and
codes.

replaced, capacity and efficiency will be reduced and the
unit may fail to operate properly or fail prematurely. A
deflector kit, RAK40, may be used with grilles that were
not designed for current AZ Series GE Zonelines. The
RAK40 contains air deflectors and gaskets that mount to
the chassis to direct the hot exhaust air away from the air
intake to allow the unit to function properly. All grilles
used with GE Zonelines must comply with requirements
of Exterior Architectural Treatments and Special Outdoor
Grilles as follows.
Exterior Architectural
Treatments and Special
Outdoor Grilles
The architectural design of a building may dictate the use of
special or oversized louvers for aesthetic reasons. Louvers
other than standard Zoneline exterior grilles may be used
on the Zoneline unit, however, these special louvers, or any
special exterior architectural treatments of the building
facade that may restrict the free circulation of condenser
airflow, should be referred to GE Application Engineering
for evaluation and approval. The following guidelines
should be followed in selecting a louver:
1. The louver must have a minimum of 65% free area.
ASHRAE defines free area as the minimum area of the
opening in an air inlet or outlet through which air can
pass. Percent (%) free area equals the X dimension
divided by the Y dimension.
2. The louver should be attached to the wall case in a
manner that will prevent recirculation of condenser
discharge air into the air inlet. If the louver is not
attached directly to the wall case, a field supplied splitter
or gasket is required between the chassis and the louver to
prevent recirculation.
It is important that the above criteria be followed since a
louver that is too restrictive or allows recirculation will
reduce the unit’s capacity and efficiency, increase the
electrical current draw, cause intermittent operation due to
the compressor overload protector shutting the compressor
off, and cause failure of the compressor overload and
shorten compressor life. Using the unit with a grille that is
too restrictive or allows recirculation may constitute
improper installation. A scale drawing of the louver section
should be sent to GE Application Engineering. To assure
the proper performance of the Zoneline unit and comply
with Underwriters Laboratories requirements, it may be
necessary to send a sample louver section (at least 16" x 42")
to GE to be tested with the Zoneline unit.

Application Comments
Use and Care Manual and installation instructions are
shipped with Zoneline units. It is important that any air
conditioning system be properly sized and applied in order
to achieve the desired temperature and humidity levels with
the space to be conditioned. Air conditioners are designed
primarily to provide heating and cooling with the additional
benefit that during operation in the cooling mode, the units
also remove some moisture from the conditioned space. The
following are some brief application comments on
undersizing, oversizing, heating, wall coverings, and air
infiltration: all are important in the proper matching of the
heating/air conditioning system to the building structure.
Undersizing: If an air conditioner is undersized (cooling
capacity is less than required for a specific application), the
unit will typically not be able to cool the space down to the
desired temperature (thermostat set point), nor be able to
remove enough moisture from the air. A result could be a
warm and humid or warm and dry conditioned space.
Oversizing: If an air conditioner is oversized (cooling
capacity is greater than required for the specific
application), the unit will typically cool the space down to
the desired temperature (thermostat set point) too quickly.
The compressor then begins to cycle on and off.
Dehumidification only takes place when the compressor is
operating. A typical result in a hot/humid climate could be
a cool, but excessively humid space.
Heating: Undersizing can result in not being able to
maintain the desired temperature level within the
conditioned space.
Wall Covering: Use of a non-permeable wall covering (some
paints, some wall papers, and other types of coverings)
which severely restricts passage of air or water vapor can
cause a severe moisture problem. Typical results could be
staining of room surfaces, wall damage, as well as mold and
mildew growth in hot/humid climates.
Air Infiltration: Excessive air infiltration can magnify
problems associated with undersizing or oversizing of an air
conditioner unit, and can be the root cause of insufficient
cooling, dehumidification, or heating. Some sources of air
infiltration include vents, gaps around windows and doors,
and improperly sealed floor, ceiling and wall joints.
Recommendation
For the above reasons it is strongly recommended that a
professional engineer be retained to match the Zoneline
with the building structure.
Air Distribution
Zoneline packaged terminal air conditioners and heat
pumps discharge air from the top of the unit through
reversible 2-position discharge louvers. Unit discharge
louvers are reversed by removing the room cabinet from the
unit, removing seven screws that hold the louver section in
place, removing the louver section and rotating it end for
end, reinstalling the louver section in the room cabinet with
the seven screws, and reinstalling the room cabinet on the
unit. The unit is shipped from the factory with the discharge
louvers at an angle of 50° off vertical. In the alternate
position the louvers will be at an angle of 40°
off vertical.
All room cabinets return air through the front of the unit.
42
High Wall Mount - For units
mounted high in the wall, the
discharge louvers should be at a
setting that provides the most
horizontal air discharge.
Recommended installation is at
least 3" below the ceiling. In
installations where units are
close to the ceiling, the most
horizontal discharge angle can
be obtained by removing the
discharge grill from the room
cabinet.
Supply Air Throw - One
Zoneline unit should not be
required to do a job obviously
requiring two or more units.
Units should be located around
large rooms according to
calculated loads or in such
fashion as to achieve balanced
air distribution in all parts of
the room. The single unit in
the “Incorrect” illustration
below obviously cannot
condition the entire room. Add
a second unit as shown in the
“Correct” illustration.

Latent System Capacity
The total capacity of an air conditioner is made up of the
Sensible capacity, the output of the unit used to remove heat
from the air in the area being conditioned, and the Latent
capacity, the output of the unit used to dehumidify the air
in the area being conditioned. For humid climates and
applications, the Sensible/Latent capacity split of the unit
should be considered. The Sensible capacity listed in the
specification charts on pages 52 and 53 are at standard
rating conditions of 95°F. dry bulb/75°F. wet bulb outdoors;
80°F. dry bulb/67°F. wet bulb indoors. The Latent system
capacity is 1.00 minus the Sensible capacity. (If the Sensible
capacity is listed at .74 the Latent capacity is .26. This means
that 74% of the capacity of the unit is used to remove heat
from the air and 26% is used to remove moisture from the
air at standard test conditions).
AZ22E07D/E
AZ52H07D/E
In some applications information about the Sensible/Latent
split, or ratio, at conditions other than the standard rating
conditions is needed. The charts below provide data at
various indoor conditions. To use the charts, first determine
which Zoneline model is being considered and refer to the
appropriate chart. Next, locate the indoor dry bulb
temperature under consideration across the horizontal axis
of the chart and draw a line straight up until it touches the
line representing the indoor wet bulb temperature of the
area; from this point draw a horizontal straight line to the
vertical axis. The point where the line touches the axis
represents the latent percent of the total capacity of the unit.
An example is shown for the standard indoor conditions of
80°F. dry bulb/67°F. wet bulb.

Formula for Calculating Operating Costs Using Above Data:
Heating* -
Heat Loss KW x Heating Degree Days x “C” x Cost per KWH
= Operating Cost
Outdoor Design Temperature Difference
*The above formula is for electric resistance heating only. Power consumption using the Zoneline Heat Pumps should be adjusted by Seasonal Performance Factor (SPF).
The local power supplier should be consulted for recommended value of “C.” This factor will vary between 17 and 24.
Cooling - Calculated Heat Gain (BTUH) x Unit Cooling Watts x Cooling Hours x Cost per KWH = Operating Cost

resistance heat, if outdoor temperature is below 46°F.,
simultaneously with heat pump if heat pump alone is
unable to maintain room temperature; or B) partial
electric resistance heat simultaneous with heat pump
operation any time the outdoor temperature is below
45°F. Selection of A or B operation is made by means of a
selector switch concealed from room occupant. In either
A or B operation the unit will switch to full resistance
heat if room temperature continues to decline or the
outdoor temperature falls below 25°F. If the outdoor
temperature is above 46°F., unit will lock-out electric
resistance heat and operate on heat pump only. Unit
shall have a switch concealed from room occupant to
allow heat pump operation to be overridden and heat
provided by electric resistance heat regardless of outdoor
temperature.
Heat pump unit shall include Reverse Cycle Defrost that
automatically begins a defrost cycle when microprocessor
determines criteria for defrosting has been met.
Defrosting shall be accomplished by systematically
ceasing heat pump operation, pausing to allow internal
refrigerant pressures to equalize, then operating the
compressor with the flow of refrigerant reversed, to allow
the hot gas to flow through the outdoor coil melting the
accumulated frost. Unit shall automatically resume heat
pump operation, after pausing to allow refrigerant
pressures to equalize, at conclusion of defrost cycle.
In the event of compressor failure during heat pump
operation, unit shall automatically switch to electric
resistance heat to maintain selected room temperature
regardless of outdoor temperatures.

Maximum Connected Load For
Deluxe Series (2200 and 3200)
The maximum connected load of a Zoneline occurs when
the unit is in resistance heating operation. The maximum
amperage shown in the tables below is the combined total of
the resistance heater and the fan motor.
In the tables below, the heater designator in the model
number is represented by an “*” in the model number
column. To find the maximum connected load, locate the
model in the left column and go across the row to the
column headed by the 9th character in the model number
or the heater watts.
The sum of the fan motor requirements TABLE A and the
heater requirements TABLE B equal the Maximum
Connected Load of the unit.

Maximum Connected Load For
Premium Series (5200)
The maximum connected load of a Zoneline unit occurs
when the unit is in resistance heating operation. To
determine the maximum amperage draw or wattage
consumption of the unit: First, find the chassis model
number in TABLE A and read the amperage or wattage of
the unit in the appropriate column; Second, find the power
connection kit to be used in TABLE B and read the
amperage or wattage of the heater in the appropriate
column.
The sum of the fan motor requirements TABLE C and the
heater requirements TABLE D equal the Maximum
Connected Load of the unit.

COOLING
Should a change in unit BTU cooling or heating be
considered?
• Did the existing unit cool the room quickly on a hot day?
And cycle OFF/ON thermostat on the hottest day. This is
an indication that unit is larger capacity than required
• Is the room being remodeled and any of the following
changed.
– Changing the windows from single pane to double or
triple pane design. Tinting, low e glass etc.?
– Are windows being made smaller?
– Is insulation being added to outside wall?
– Room vent air being changed?
• Should engineering calculations be made to determine
BTUs necessary for cooling and heating?
• When engineering calculations are made to determine the
correct BTU size for cooling operation, a smaller BTU
model is often recommended. A smaller BTU model will
run longer to cool the room but less power (KWH) will be
used. Money is saved when less KWH (kilowatt hours) are
consumed.
– Smaller BTU models are generally quieter during
cooling and heating operations.
– With the smaller BTU model running longer the
room is generally less humid. Humidity control is very
important in the warm humid areas, and normally
guests will be more comfortable in rooms with lower
humidity.
WALL CASE
• New GE model will install into existing GE Zoneline wall
case. (First Zoneline made in 1961) (Consider using wall
case insulation RAK901L in existing wall cases.)
• Zoneline may fit into existing competitive wall case. (If
wall case extends into room and is not insulated consider
using insulation kit RAK901L)
• Existing outdoor grille may need to be changed or
modified when an old chassis is replaced. Outdoor air flow
patterns have changed and this may dictate the need for
outdoor grille replacement or modification.
SAVINGS
• New unit with higher EER (Energy Efficiency Ratio) than
older existing unit should provide energy savings.
Calculations can be made to estimate annual savings.
• Reduce demand charges with high efficiency models.
• Some utility companies may offer rebates/incentives for
installing heat pump models - check with serving utility
company.
• When engineering calculations are made to determine the
correct BTU size for cooling operation, a smaller BTU
model is often recommended as the replacement model.
A smaller BTU model will run longer to cool the room but
less power (KWH) is used. Money is saved when less KWH
(kilowatt hours) are consumed.
– Smaller BTU models are generally quieter during
cooling and heating operation.
– With the smaller BTU model running longer, the
room is generally less humid. Humidity control is very
important in the warm humid areas.
HEATING
In most areas of the U.S.A., the greatest operational costs are
in heating operation. Analyzing the cost of heating with a
heat pump vs electric heat may show strong incentives to
replace older electric heat models with new higher efficiency
heat pump models. Seasonal performance (SPF) reports
can be provided to estimate the annual savings. Contact
your General Electric (Zoneline) sales person to obtain
this report.
OTHER POSSIBLE SAVINGS
– Minimize the electrical total connected load (use
correct heater size).
– Reduce demand charges using heat pump models
with the proper electric heater size and resistance
heat lockout, and heat pump operation to approx.
25°F.
• If a case extension is used on the existing wall cases, the air
splitters installed in these case extensions must mate and
seal to the ends of the outdoor coil of the new unit. This
may require moving the splitters.

Don’t hesitate to ask for information or assistance from your
General Electric Zoneline salesperson.
IMPORTANT
Correct BTU size for cooling and heating needs to be
determined. Most modern construction utilizes thermal
efficient materials and components. In most new
construction motel rooms, the smallest BTU Zoneline is
adequate for the cooling needs. This is contrary to common
practice. An accurate engineering study and calculation
should be made to determine the cooling and heating
requirements.
– Smaller BTU models are generally quieter during
cooling and heating operation.
– With a smaller BTU unit running longer the room is
generally less humid. Humidity control is very
important in warm humid areas.
– Smaller units minimize the electrical total connected
load (use the correct heater size and BTU cooling
size unit).
– Using the correct size resistance heater may reduce
utility demand charges.
– Reduce operating cost by using properly sized units.
Consider using heat pump models with properly sized
heaters with resistance heat lockout and heat pump
operation to approx. 25°F.

ELECTRIC HEAT VS HEAT PUMP
• In most areas of the U.S.A., the greatest operational costs
are in heating operation. Analyzing the cost of heating
operation by heat pump vs. electric heat may show strong
incentives to choose heat pump models.
