HEATER WATTAGE AND POWER CONNECTION KITS
Power connection kits are required on all Zoneline chassis. (See chart.)
The correct kit for the installation is determined by the voltage and amperage of the electrical circuit and the means of connecting the unit to the building wiring. If the unit is to be plugged into a receptacle, a line cord kit would be used; if the unit is to be permanently connected, a direct connector or a permanent connection kit would be used.

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 the 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.

GE ZONELINE® WITH Makeup Air
Add the benefit of our second generation of Makeup Air to the industry’s most trusted PTAC, with GE Zoneline®
Makeup Air. Factory-installed and tested, the Makeup Air module is an independent secondary system that provides outdoor air continuously.
FEATURES
• Dedicated fans in the Makeup Air system that are
adjustable to 6 pre-set fan speeds from 25 to 50 CFM.
• Provides outdoor air anytime the unit is plugged into the
power source (even if unit is turned off).
• Dehumidifies incoming outdoor air when OD humidity
is greater than 55% RH and above 50° F.
• Dehumidifies at a rate of 5 -6 pints/24 hours.
• Pairs with an approved occupancy sensing system
to shut off Makeup Air and close the duct door when
the room is unoccupied (if desired).
• Modular/Reliable design for improved serviceability.
• Factory installed and tested.
• GE Zoneline with Makeup Air is covered by the same
warranty as our Zoneline.
• Approved by leading hotel brands.
• Optional MERV 13 Makeup Air Filter kit available (RAK13)
The GE Zoneline Makeup Air system provides an option to standard building ventilation designs.
With dedicated fans in the Makeup Air system (adjustable to 6 pre-set fan speeds), the Makeup Air Zoneline can provide positive pressure Makeup Air for those projects looking for alternatives to having a rooftop system ducted to each individual room.
The main system provides the standard individual room zone control in both cooling and heating applications. The
Makeup Air module is a secondary sealed system with dedicated fans that offers 6 pre-set fan speeds (25-50
CFM) of continuous dehumidified Makeup Air.
DOOR VENT & OCCUPANCY SENSING
Zoneline Makeup Air features a motorized vent door.
When paired with an approved occupancy system and the room is unoccupied, the vent door will close, and the
Makeup Air system will shut down.
This design saves energy and money by running the makeup system only when needed, while allowing the PTAC system to operate independently.
AGENCY LISTING
Both the Makeup Air Module & Zoneline system are approved by UL, CEC, NRCAN & AHRI and comply with ASHRAE 90.1-2013 minimum efficiency requirements for PTACs.
THE MAKEUP AIR
MODULE COMES
INSTALLED IN SELECT
ZONELINE PTAC UNITS.
DESIGN CONSIDERATIONS
• Makeup Air systems are not recommended for installation
within 1-2 miles of coastal areas.
- Units are not corrosion protected
- To avoid bringing corrosive air into the living space
• The Makeup Air Module will increase room load
requirements for both heating and cooling.
- Consult with your architect or engineer to ensure proper
sizing of the PTAC/PTHP unit to accommodate this
additional load.
- Due to the additional heating and cooling load,
energy costs of the room will increase with the use
of Makeup Air.
- Because Makeup Air increases room BTU load
requirements and requires additional PTAC cooling
or heating, the building’s electrical needs may
be impacted.
• For best air temperature regulation, remote thermostats
should be used with Makeup Air models.
• With the additional dehumidification of outside air, more
condensate will be generated and therefore an internal
or external piped drain line is recommended.
• Total building air design should be considered with
Makeup Air PTAC’s/PTHP’s and especially with occupancy
sensing thermostats and the ability to turn off the Makeup
Air and close the vent door when the room is unoccupied.
• With the additional pathway/opening for outside air,
additional consideration should be used for areas with
high exterior noise (traffic, airports, etc.) to not
unintentionally bring noise into the room and disturb
the guest.
• It is the architects’/engineers’/contractors’ /customers’
responsibility to verify all state and local codes to ensure
product meets local code requirements.
NOTE : Ducted installations should not be used with
Makeup Air models.

THE ZONELINE AZ45 AND AZ65 SERIES have changes suggested by customers and enhancements from
GE Appliances Engineering to make product improvements and meet the changing environment.
• Quieter Operation
• Ease of access—fewer screws and number of parts
• Make up air module
• Cross-flow blower across the product line for quieter operation
See the “Features and Benefits” section for in-depth explanation of these changes and the industry-leading features of GE Appliances Zoneline retained from previous series.
DRY AIR 25
THE ZONELINE AZ45 SERIES INCLUDES “DRY AIR 25" MODELS, WHICH REMOVE 20-35%
MORE MOISTURE THAN OTHER ZONELINE MODELS*.
DRY AIR 25 MODELS COOLING WITH
RESISTANCE HEAT
• Removes 20-35% more moisture than standard
Zoneline models *
• Dry Air is a separate sealed refrigerant system
—No mechanical parts
—No special maintenance required
• Helps maintain lower relative humidity in rooms
• Maintains comfort at slightly higher room temperatures
—Reduces operating costs
—Provides comfort without overcooling
• Corrosion treatment is standard
• Excellent choice for humid climates
• Available in 7,000, 9,000 and 12,000 BTU sizes
The Dry Air 25 system, a heat pipe, is a hermetically sealed heat transfer surface installed in a “saddlebag” configuration around the indoor (evaporator) coil of the Zoneline unit. This coil arrangement will transfer heat from the front coil of the saddlebag to the rear coil without power consumption.
This assembly uses R-410A as the refrigerant and is not connected to the regular Zoneline refrigerant circuit.
As warm, humid air is pulled through the front (precool) section of the heat pipe, the heat removed from the air is absorbed by the refrigerant, causing the refrigerant to change to a gas and flow to the rear (reheat) section of the heat pipe. The air leaving the precool section of the heat pipe is cooler and at a higher relative humidity level than the room air. The pre-cooled air is further cooled as it passes through the evaporator, consequently allowing the evaporator coil to remove more moisture.
When the cold air from the evaporator comes in contact with the re-heat section of the heat pipe, the heat that was removed by the pre-cool section is added back to the air and the refrigerant in the heat pipe condenses and flows back to the pre-cool (front) section. The air discharged into the room by this process is much drier, creating a more comfortable room condition.
The Dry Air 25 models center around GE Appliance’s heat pipe technology. This technology enables Dry Air
25 to remove 20-35% more moisture from the air than other leading manufacturers’ packaged terminal air conditioners. This helps maintain room comfort at a higher room temperature, reducing operating costs.
The Dry Air 25 keeps a room cool and dry, and this is the most important benefit when it comes to the occupant of the room—hotel guests, apartment residents, students. In a hot, humid climate, getting away from the humidity is just as important as getting away from the heat, and the Dry Air 25 is the perfect solution. The dehumidification of the Dry Air 25 has been verified by the same AHRI test conditions under which standard units are rated.
* Varies when comparing dehumidification rates of the 7,000/9,000/12,000 BTU base models to their Dry Air model counterparts.

STANDARD PHYSICAL DIMENSIONS
GE Appliances has maintained the same wall sleeve dimensions since 1961—42" wide x 16" high x 13-3/4" deep—making replacement of older units easy.
WEATHER RESISTANT SYSTEM SEAL
Per AHRI, the air infiltration rate shall not exceed 19.3 CFM at the perimeter of the wall sleeve where it normally projects through the wall.
With superior design and premium materials, a properly installed Zoneline unit in an undistorted sleeve keeps air leakage to a minimum (5 CFM).
COMPOSITE BASE PAN
The base pan is made of SMC and comes standard on all models. Since the base pan is exposed to the elements and is a water bearing device, this composite (non-metal) base pan eliminates the concern or problem of rusting metal base pans.
HEATER SIZES TO MEET ROOM REQUIREMENTS
All units are equipped with a universal heater— the resistance heat output is determined by power connection kit.
230/208 Volt Units
15 AMP Circuits—2.4/1.96 KW—RAK315P and RAK315D

UNIT CONTROLS
AZ45 and AZ65 Series—touch pad controls with large, white LED readout with auto dimming feature, eliminates the need for the control cover.
HIGHLY FEATURED MICROPROCESSOR CONTROLS
Microprocessor controls are programmed to interface with the temperature sensors to maximize comfort conditions or the room occupant and provide outstanding performance features.
Thermistors are used to sense small changes in temperature to give excellent room control and allow the microprocessor to monitor and react to changing conditions.
ELECTRIC RESISTANCE HEAT LOCK-OUT
To maximize the savings of the heat pump operation, the
Zoneline ® heat pumps do not utilize the resistance heater when the outdoor temperature is above 46°F (and below
85°F) during normal operation. However, the resistance heat is still used in the quick heat recovery feature.
AUTOMATIC EMERGENCY HEAT
Automatically uses electric resistance heat if the heat pump output is not sufficient to maintain selected room temperature.
REVERSE-CYCLE HEAT PUMP DEFROST SYSTEM
• Standard on all Zoneline AZ65 Series heat pumps
• Enables heat pump to operate at lower temperatures when other systems switch to more expensive electric resistance heat.
See pages 20–21 for discussion of heat pump operation and defrost systems.
HIGH-TEMPERATURE HEAT PUMP OPERATION
PROTECTION
• Automatically protects the compressor if heat pump is operated with high outdoor temperatures.
• Power to the outdoor fan is turned off if the indoor coil gets too hot during heat pump operation to prevent damage to the compressor.
QUICK HEAT RECOVERY—HEAT PUMP UNITS
When the unit operation is changed from OFF or COOL to HEAT, the electric resistance heaters are used to warm the room to the thermostat set point for the first cycle.
This provides faster room temperature increase for greater guest comfort.
FAN MOTORS—PERMANENTLY LUBRICATE D
• All units have two fan motors for quiet operation and maximum operating efficiency.
• Motors are permanently lubricated to reduce maintenance and totally enclosed to keep dirt and water out of the motor windings.
OUTDOOR FAN
The unit automatically selects the most efficient speed for the outdoor fan. The operating sound level is lower when the outdoor fan can operate in low speed, yet there are situations where it must operate in high speed. The unit changes the fan speed automatically.
INDOOR FAN SPEED SELECTIONS—HIGH/LOW
Unit may be operated in HIGH HEAT, LOW HEAT,
HIGH COOL or LOW COOL. The unit also provides the option of selecting either HIGH or LOW speed for
Fan-Only operation.
FAN-CYCLE SWITCH— “SMARTFAN”
• Unique “SmartFan” allows the unit to operate the
indoor fan continuously in cooling operation and in
cycle mode for heating, to provide better guest
comfort. Smart Fan provides air circulation in summer
for its help in cooling and eliminates complaint of
cold-air draft during the heating season.
• Eliminates the need for changing fan-cycle
switch seasonally.
• “SmartFan” settings are controlled via the auxiliary control setting push button.

FEATURES & BENEFITS
(CONTINUED)
COMPRESSOR RANDOM RESTART
In the event of a power failure, all compressors attempting to restart immediately when power is restored can result in a power surge that can cause another power interruption.
The microprocessors in the Zoneline units have a random restart logic system that prevents all units from starting at the same time.
ROTARY COMPRESSOR
Provides smoother operation for quiet, dependable service. GE Appliances has used rotary compressors since 1961.
COMPRESSOR RESTART DELAY
Zoneline units are designed to provide a minimum of three minutes of compressor-off time to allow refrigerant pressures to equalize before restarting to prevent compressor damage.
Zoneline units are also designed to provide a minimum of three minutes of compressor-run time to prevent room occupant disturbance due to short-cycling of the air conditioner.
FREEZE SENTINEL
• Detects low room temperature and turns on heater to help protect against damage caused by freezing room temperatures.
• The electric heater turns on at 41°F and warms the room up to 46°F and shuts off.
• Freeze Sentinel may be turned off via the auxiliary control.
HEAT SENTINEL
The property owner may choose to activate the Heat
Sentinel feature on the Zoneline unit. If the Heat Sentinel is activated and room temperature reaches 85°F (even when the unit is in the “OFF” mode), the unit will automatically start the air conditioning operation and will shut off when the room temperature reaches
80°F. This will help dehumidify the air and lower high temperatures so the guest will not be entering an extremely hot room.
INDOOR COIL FROST CONTROL
Prevents indoor coil from freezing and causing complaints due to lack of cooling. Frost can form on the indoor coil when the unit is operated in cooling when outdoor temperatures are low. The unit automatically shuts the compressor off (and keeps the indoor fan running) until the indoor coil temperature warms to the point where frosting will no longer occur.
TRANSFER FAN INTERFACE
A 24 VAC connector is available (RAKCDC) to operate a relay to control a fan mounted in a wall to move conditioned air into another space. The electrical power for the operation of the transfer fan itself is not provided by the Zoneline unit. Transfer fans and their controlling relays, power and wiring are field supplied.

FEATURES & BENEFITS
(CONTINUED)
CONCEALED MANUAL VENT CONTROL
An open ventilation door on GE Appliances Zoneline ® packaged terminal air conditioners and heat pumps allows outside air to enter the room through a screen-covered opening in the weather barrier that separates the indoor and outdoor sections of the unit.
A concealed lever, located along the left side of the unit under the front cover, is used to open and close the vent door.
NOTE: Two shipping screws must be removed from the vent door before use.
The manual vent door has infinite adjustability with the slide rod and wing nut to meet everyone’s needs. Simply tighten the wing nut at the desired opening level. Positive vent door closure and tightening of the wing nut prevents accidental opening and unwanted air infiltration.
CORROSION PROTECTION (OPTIONAL)
AZ45 and AZ65 Series units may be ordered with special protection to better withstand damage from salt air and salt water in seacoast or other corrosive areas.
Corrosion protection is standard on the
Dry Air and 265V models.
Makeup Air module units and heat pump units
with ICR are not available with corrosion protection
and should not be installed in seacoast or other
corrosive environments.
Units installed in corrosive areas should use the RAB77B wall sleeve and be examined/cleaned more frequently than normal installations.
I NTERNAL CONDENSATE REMOVAL (ICR)
See page 36 for a discussion of the internal AZ65
Series heat pumps.
DRY AIR 25
Moisture removal is an important function of an air conditioner. People are more comfortable at higher temperatures when the humidity level is relatively low.
Air conditioners operate with less energy consumption when the room temperatures are set higher.
The GE Zoneline AZ45 Series with the Dry Air 25 heat pipe application removes 20–35% (varies by model) more moisture than the standard AZ45 Series unit.
Customers who are using the Dry Air 25 report a fresher-smelling room as a result of the lower humidity levels, as well as lower operating costs.

Outside ambient air entering the room through this screened vent opening is not conditioned. This unconditioned air becomes mixed with the conditioned air that is circulated by the indoor fan. This air mixture generates an additional heat load/heat loss that causes the unit to run longer and may translate into higher operating costs.
For each CFM of air to enter the room, an equal amount of air must be removed through exhaust fans in the bathroom or rooftops. Greater amounts of air will be introduced (from chart shown above) depending on the size of the exhaust fan.
Zoneline vent openings are not intended to be the source of make-up air for building ventilation systems since the vent is not continuously conditioned or powered by separate fans.

CENTRAL DESK CONTROL
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 (CDC). 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, turning the air conditioner 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.
There is a wide variety of devices available, each with its own benefits and constraints. While GE Appliances does not offer components that are external to the unit for a Central Desk Control system, GE Appliances
Zoneline units are compatible with most CDC and energy management systems.
All GE Zoneline AZ45 and AZ65 Series units are compatible with simple on/off 2-wire Central Desk Control
(CDC) systems. Consult with the provider of the energy management system to be sure it is compatible with
GE Zoneline units.
All GE Zoneline units have a port available and offer accessory (RAKCDC) to provide an CDC interface to most of the energy management systems.
Control power to the switch (24 VAC) is provided by the GE Zoneline unit.

Freeze Sentinel and Heat Sentinel remain 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 or high limit temperature, the unit will automatically turn on until it reaches the preset shutdown temperature (46°F heating, 80°F cooling).
Connecting the Zoneline unit 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.
Please see page 55 for installation recommendations for the Central Desk Control wiring.

1. When the switching device closes the circuit of the CDC conductors, the unit operation stops.
2. Do not use a common bus (at the unit or at the switch panel) in the wiring. Both wires comprising the circuit must connect to the unit connectors and to the controlling switch. Running one wire from one unit to another unit is common busing and may damage internal components or cause erratic operation of the system.
3. A 24-volt transformer is contained within the Zoneline unit. No external voltage may be applied to the unit through the CDC terminals. (Voltage on the CDC conductors is 24 volts AC.)

REMOTE THERMOSTAT CONTROL
In many installations, control of the operation of the unit at a location remote from the unit itself is desired. A unit mounted high in the wall or over a door, for instance, where the unit-mounted controls are inaccessible, can be connected to a wall-mounted thermostat. Other installations may use remote thermostat control for design or performance enhancement. The unit is connected to the thermostat by low-voltage wiring which permits the operation of the unit to be selected and the temperature sensed at the thermostat.
Important Notes:
Remote thermostat wiring should not be run through the wall sleeve. Thermostat wiring should exit the wall below the unit and enter the unit between room cabinet and chassis. Wire molding may be used to hide thermostat wiring. If a sub-base is used, the thermostat wiring may be concealed by the sub-base. Thermostat wiring should not be run parallel to line voltage wires since induced current may cause erratic operation.
All Zoneline ® AZ45 and AZ65 Series units are adaptable to
Class 2 remote low-voltage thermostats. The only additional field-supplied components are the remote thermostat and wiring necessary to connect it.
The controls on the unit are not functional when the remote control function is used.

RESISTANCE HEAT MODELS
The Zoneline AZ45 series resistance heat units may be connected to a single-stage thermostat designed for use with cooling with electric heat systems. GE Appliances offers four thermostats compatible with the
AZ45 Series unit.
The remote thermostat-Class 2 option (Mode 6 in the auxiliary control setting) must be turned ON to enable remote thermostat control. Refer to installation instructions packaged with the chassis.
Please see page 51 for installation recommendations for the remote thermostat wiring. Compatibility of other thermostats considered for use with GE
Appliances Zoneline units is the responsibility of the customer.
The control voltage on the remote control conductors is
24-volts AC. The AC voltage may not be compatible with some solid-state thermostats.
If using a 1-fan speed remote thermostat, the fan speed for the AZ45 Series in remote thermostat operation is selected by the connection of the fan wire from the thermostat to either the HIGH or LOW wire on the remote thermostat connector. See the sketch of the connector below for the color of the HIGH and LOW fan-speed wire.
Operating the unit in low fan speed reduces the operating sound level of the unit.
Freeze Sentinel and Heat Sentinel remain 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 operation.
See page 16 for additional information on the CDC system.
Unit temperature-limiting settings are not functional when unit is connected to a remote thermostat.
NOTE: The low voltage transformer which powers the remote thermostat (and other controls) is
“self-recovering” from potential wiring shorts. Should you lose low voltage control power (to the thermostat and the display panel on the unit), remove power to the unit, check the thermostat wiring for shorts, correct the issue and reapply power to the unit.
NOTE: With the new AZ45 and AZ65 Series, thermostat twinning is allowed, where more than one unit may be connected to a single remote thermostat. In order to accomplish this, ONLY ONE

HEAT PUMPS & ENERGY SAVINGS
Heat pumps save energy and cost less to operate than units with electric resistance heaters as the only heat source. Just as the EER (Energy Efficiency Ratio) 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 used for electric resistance heat.
GE Zoneline heat pumps are designed to provide cost-efficient heat pump operation while monitoring room conditions to maintain comfort.
The Zoneline AZ65 series employs extensive software and logic that monitors and reacts to both outdoor and indoor temperatures to determine the heat source.
This increases energy savings by operating longer in the heat pump mode.
Just as in air conditioning operation, the compressor is used in heat pump operation. The difference is that in heat pump operation, the hot refrigerant gas is directed to the indoor coil rather than to the outdoor coil. With the indoor fan, room air circulates over the indoor coil, gains heat from the coil and distributes it into the room.
At some point as the outdoor temperature falls, the heat pump cannot extract as much heat from the outdoor air to maintain the temperature of the room. For this reason, all packaged terminal heat pumps also have electric resistance heaters as backup to heat pump operation.
The point where Packaged Terminal Heat Pumps cease heat pump operation and change to the more expensive resistance heat (to maintain room temperature) is called the “switchover point.” It is important to compare the switchover point of the various manufacturers since it may occur at higher outdoor temperatures with other brands where savings from the GE Zoneline heat pump operation could still be realized.
Zoneline AZ65 series heat pump units, with their extensive software and features, react to the indoor and outdoor temperatures to determine the best heat source to provide comfortable room conditions for the guest
AND energy.
BALANCE POINT
An important consideration in the selection of a heat pump unit is the “balance point” of the installation— 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.
Virtually every room is unique—with different insulation, different sizes and types of windows, different types of construction and different directional exposures.
All these variables, as well as geographical location, must be considered in order to determine the balance point. For these reasons, a professional engineer should be engaged to calculate the heat loss of the space and specify the heat pump unit required.

HEAT PUMPS & ENERGY SAVINGS

HEAT PUMP OPERATION—ZONELINE AZ65 SERIES
Heat sources: Heat pump, heat pump with partial electric resistance heat, or electric resistance heat.
Zoneline 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.
Zoneline heat pumps are designed to help ensure 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. Quick Heat
Recovery is designed to allow the temperature of a 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 below in the Heat
Source Logic chart) when the thermostat calls for heat again.
ZONELINE HEAT PUMP HEAT SOURCE LOGIC
The chart below indicates the standard heating source of the Zoneline AZ65 Series heat pump unit 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
Heat Source Logic shown in the prior chart.
For more information about the Quick Heat Recovery feature, see page 11.
The full heat output of the resistance heater is dependent upon circuit amperage and the power connection kit used.
See pages 4, 43–45 and 53 for information on power connection kits and available heater capacities.
An option is provided in the auxiliary controls (Mode 8) to allow the unit to operate only in resistance heat. The use of this option significantly increases the cost for heating.
BOOST HEAT
The Zoneline AZ65 series offers a Boost Heat option feature that utilizes partial supplemental resistance heat at the same time as the heat pump operation. The boost heat feature changes stage one heating (heat pump) to be heat pump with partial resistance heat. Stage two heating stays as full resistance heat. This applies to both unit control and remote thermostat control.
NOTE: Heat Pump and full resistance heat shall never be on at the same time.
HEAT PUMP DEFROST
Zoneline heat pumps utilize a reverse-cycle, demanddefrost system to extend heat pump operation and increase savings from extended operation.
The microprocessor determines the need for defrosting from criteria based on continuous compressor run time, outdoor air temperature and outdoor coil temperature.
When defrosting is required, the unit reverses the flow of refrigerant to direct the hot gas into the outdoor coil to melt the frost buildup.
Before and after the reverse-cycle defrost, the unit shuts off the compressor to allow the refrigerant pressures to equalize throughout the system. During these periods of pressure equalization, the full resistance heat capacity of the unit is activated to help ensure room comfort conditions during the defrost cycle. The unit remains in the defrost cycle for a minimum of three minutes and up to a maximum of nine minutes. The defrost cycle terminates when the outdoor coil reaches a temperature of 68°F or the maximum time has been reached.
HEAT PUMP CONDENSATE
Zoneline AZ65 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.
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 requirements of a particular installation will allow no dripping of condensate water from the wall sleeve, the installation of an internal or external drain system is recommended.
See pages 36–38 for more information on heat pump condensate.
Units with an ICR system may not be installed in seacoast or other corrosive environments.

APPLICATION COMMENTS
It is important that any air conditioning system be properly sized and applied in order to achieve the desired temperature and humidity levels in the space to be conditioned. Zoneline units 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.
louvers are reversed by removing the room cabinet from the unit, removing four screws that hold the louver section in place; removing the louver section and rotating it end for end, reinstalling the louver section with the four screws, and reinstalling the room cabinet on the unit. The unit is shipped from the factory with the discharge louvers at an angle of 45° off horizontal. In the alternate position, the louvers will be at an angle of 65° off horizontal.
All room cabinets return air through the front of the unit.
UNDERSIZING
Cooling: 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. The result could be a warm and humid or warm and dry conditioned space.
Heating: Undersizing can result in not being able to maintain the desired temperature level within the conditioned space.
45°
45°
65°
65°
OVERSIZING
Cooling: 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. Since dehumidification only takes place when the compressor is operating in the cooling mode, typical result in a hot/humid climate could be a cool but excessively humid space.
Wall Covering: Use of non-permeable wall coverings (some paints, some wallpapers, 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 problems. 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 size of the Zoneline unit with the building structure.
AIR DISTRIBUTION
Zoneline packaged terminal air conditioners and heat pumps discharge air from the top of the unit through reversible two-position discharge louvers. Unit discharge
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 greatest horizontal discharge angle can be obtained by removing the discharge grille from the room cabinet.
For best room control, a remote wall thermostat is recommended.
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.

A choice of wall sleeves is available for Zoneline ® units.
RAB71B — This insulated sleeve is constructed of heavygauge galvanized steel and finished with a baked-enamel finish for protection and appearance. Design of the sleeve provides for support of the chassis and free draining of any water entering the wall sleeve. A petroleum microcrystalline wax is applied at critical points of fabrication to seal against moisture. The dimensions of the
RAB71B wall sleeve are 42" wide by 16" high by 13-3/4" deep, the same dimensions as the original wall sleeve for
GE Zoneline units built in 1961. The RAB71B wall sleeve is also available in depths other than the standard depth.
It is available on special order as: RAB7116B – 16" deep ;
RAB7118 – 18” deep; RAB7120 – 20” deep; RAB7124B –
24" deep.
All these special-order deep wall sleeves are insulated and have sheet-metal dividers, or splitters, to prevent the recirculation of condenser discharge air.
RAB81 — Heavy gauge steel wall sleeve with insulated top and sides in a 4 piece “Quick Snap” universal design. This easy to assembly product is shipped in an easy to handle box making it better for shipping and better for the job site. Can also be ordered and shipped preassembled as the RAB81B .
RAB77B — This non-insulated wall sleeve is molded from fiberglass-reinforced polyester compound. This sheetmolded compound (SMC) wall sleeve offers outstanding strength, durability, color retention, water integrity and corrosion resistance. The dimensions of the RAB77B wall sleeve are 42-1/8" wide by 16-1/4" high by 13-7/8" deep.
• Wall sleeves are of universal design, accepting all
Zoneline chassis of current design as well as all
GE Appliances Zoneline chassis produced since 1961.
• Drain holes are provided in the rear of all wall sleeves to permit excessive cooling condensate water, heat pump condensate or precipitation entering the wall sleeve to drain freely. A drain kit may be connected to the wall sleeve to control any water draining from the wall sleeve.
See pages 37–38 for information on RAD10 Drain Kit .
WALL SLEEVE INSTALLATION DATA
GENERAL
Generally, Zoneline ® units 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 sleeve allows installation flexibility; from flush with the finished interior wall to a minimum of 1/4" of the wall sleeve extending beyond the finished exterior of the building. Special consideration must be given to installations where the wall sleeve does not extend a minimum of 1/4" beyond the finished exterior wall.
See pages 32–33 for information on this type of installation. The unit may be installed high in the wall and these installations usually require a remote thermostat (discussed on pages 17-19).
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 28 for required wall opening dimensions.
Minimum recommended interior and exterior sleeve projections for standard wall thicknesses are shown in the drawings in this manual. The sleeve may be installed flush with the finished indoor wall. Special attention must be paid to room-side sleeve projection when the unit is installed in a ducted application as shown on pages 40–41.
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 sleeve extension or use one of the special-order RAB71 deep wall sleeves. Such extensions must be carefully flashed and sealed both to the wall sleeve and to the wall to ensure water integrity.
This is necessary to ensure that any water entering the wall sleeve, 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 sleeve without the possibility of capillary action drawing the water into either the room or the wall cavity. In an installation where the sleeve is recessed less than 3" from the outside surface, flashing and sealing may be all the modification 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 32–33 for suggested detail. Since the installation of a sleeve extension requires a considerable amount of attention, we recommend using one of the deep wall sleeves if the standard sleeve is not of sufficient depth.
Mounting an outdoor grille or louver section to the building face may cause 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. Gaps between the outdoor coil and the louver section may allow condenser air recirculation and affect the operation of the unit. See page 43 for requirements for custom louvers.
The wall sleeve should be level from side to side and from level to 1/4 bubble tilt to the outdoors. The condensate disposal system in the unit is designed to dissipate the condensate water generated during cooling operation in accordance with AHRI standards and actually uses this water for maximum unit efficiency. A level unit will also ensure proper drainage from the RAD10 drain kit to a building internal drain and proper performance of the Internal Condensate
Removal (ICR) system optional on heat pump units.
SUB-BASE
The sub-base is an optional accessory for the Zoneline unit. It is discussed with the wall sleeve information since deciding whether or not to use a sub-base in the installation is a factor in the location of the wall opening. National Electrical Code ® (NEC) requires that air conditioning units connected to voltages in excess
ARCHITECTS & ENGINEERS DATA MANUAL AZ45/AZ65 SERIES
WALL SLEEVE INSTALLATION DATA
(CONTINUED) 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, consult Article 440 of the NEC or the local electrical inspector. 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 to 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 unit.
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 make the use of a sub-base a viable means of permanent connection.
RAK204U — The RAK204U Series of sub-base provides a design that fits the site needs and is available for use with Zoneline PTAC/PTHP units. The RAK204U will most likely be used for support of the wall sleeve 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 RAK4002D junction box, perform 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.
230/208-volt receptacles can also be mounted in the cover plate for easy access when direct-connect wiring is not required. 265-volt units are to be “Permanently
(or Direct) Connected” and the external receptacle
(when wiring is not enclosed in a chaseway) does not meet this requirement. A knockout for a fuseholder or a disconnect is also provided in the cover plate.
The 230/208-volt sub-bases include a short, sub-base power connection kit. Since sub-base connected units are not considered to be line-cord connected, a Leakage
Current Detection Interrupter or Arc Fault Current
Interrupter device is not necessary.

Receptacle is NEMA7-30R with 18" of #12AWG wires attached to the receptacle. Chaseway and 3’ Power
Connection Kit included.
The junction box for 265-volt units is shipped with the chassis since all 265-volt units are to be “permanently
(or direct) connected.”
There are separate internal compartments to permit separation of low-voltage (Class 2) connections from line-voltage connections as required by National Electrical
Code (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 sleeve is installed.
The sub-base attaches to the RAB71B wall sleeve with two clips (field-assembled) that are screwed into fielddrilled holes in the bottom front flange of the wall sleeve.
It attaches to the RAB77B wall sleeve with clips that fit over molded ribs without requiring the use of screws into the wall sleeve. (See page 35 for illustration.) Since the sub-base extends under the wall sleeve, clearance from the inner edge of the wall sleeve to the finished wall must be 2-3/8" or greater. The sub-base has four leveling legs and adjustable side channels to enable the area under the wall sleeve to be enclosed. Clearance from the bottom edge of the wall sleeve to the finished floor must be between 3" and 5".
The sub-base may be used as support for the chassis and wall sleeve in installations where the wall is of insufficient thickness to provide secure mounting of the wall sleeve.

SUB-BASE
(CONTINUED) 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 sleeve must be done correctly.
and at the front of the wall sleeve. Sub-base (RAK204
Series) with four leveling legs provides an excellent support for the unit in this type of installation.
(See page 30 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 sleeve. Similar filler panel material may be installed around the sleeve for appearance and weather seal.
ARCHITECTURAL WINDOW/
LOUVER INSTALLATION
Many installations utilize an architectural window/louver combination to enhance the exterior appearance of the building. The exterior grille for the air conditioner is built as an integral part of the window frame. An internal drain system is highly recommended for these installations
(see page 38). When this type of installation is made, there must be provision in the grille work for condensate water to drain to the exterior (including the overflow relief drain holes) and not be routed back into the interior of the building or into the wall cavity. Failure to allow for the drainage of condensate water can cause extensive damage to structural components.
The problems associated with the lack of condensate drain consideration often show up shortly after the air conditioners are turned on in a new building. New buildings that have been virtually wide-open during construction have a significant amount of moisture in the air and in the building components that the air conditioners start removing as they operate.
The free area in the louver section must also comply with the requirements shown on page 43.
The wall sleeve should be anchored to the architectural window/louver section to reduce air infiltration and excessive vibration of the chassis and wall sleeve during unit operation. Field-fabricated and -installed sleeve angles are the recommended method of securing the wall sleeve to the window/louver framework.
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 sleeve. This additional support should be located both near the wall
MASONRY WALL CONSTRUCTION
The wall sleeve should be installed during construction and lintels must be used to support the blocks above the wall sleeve. The wall sleeve will not support the concrete block. The installation instructions show how the wall sleeve must be secured to the masonry and caulked. Do not remove the cardboard stiffener supplied with the wall sleeve until ready to install the chassis. (See page 31 for details of installation in masonry wall).
For existing masonry construction, wall openings must be made by removing 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 sleeve.
Anchor bolts are normally required to secure the sleeve to the wall and shims may be required to prevent distortion of the wall sleeve when securing the wall sleeve to the wall. Field- supplied sleeve angles can be used to position and secure the wall sleeve to the wall and to cover oversized wall openings.
BRICK, FRAME, STUCCO AND
SHINGLE CONSTRUCTION
For new construction, the opening for the wall sleeve should be framed and the wall sleeve inserted into the opening during construction. Lintels must be used when the building material is heavy and is not self-supporting
(such as brick). The wall sleeve 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 sleeve 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 sleeve. 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 sleeve and provide adequate support for sleeve and chassis.
As shipped, the RAB71B Series or RAB77B is ready for installation.

(CONTINUED)
PREPARATION OF THE WALL SLEEVE FOR ALL
TYPES OF CONSTRUCTION
Do not remove the stiffener from inside the wall sleeve or the weather closure panel from the outside face of the wall sleeve until the outdoor grille and chassis are ready to be installed.
1. Position the wall sleeve into the wall. The room-side edge of the RAB71B or RAB77B wall sleeve 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. The outside edge of the wall sleeve 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 sleeve, and to facilitate the installation of an accessory drain, if used.
If the minimum exterior dimensions are not met, refer to pages 32–33.
The wall sleeve should be level from side to side and from level to 1/4 bubble tilt to the outdoors. The condensate disposal system in the unit is designed to dissipate the condensate water generated during cooling operation in accordance with AHRI standards and actually uses this water for maximum unit efficiency. A level unit will also ensure proper drainage from the RAD10 drain kit to a building internal drain and proper performance of the Internal
Condensate Removal (ICR) system optional on heat pump units.
2. The wall sleeve 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 on page 28.) Mark the wall sleeve on each side 2" from the bottom and 2" from the top at a point where basic wall structure is located.
Drill wall sleeve and use fasteners appropriate for wall construction. All holes for fasteners in the side of the wall sleeve must be at least 2" up from the bottom of the wall sleeve. Never locate screws or put other holes in the bottom of the wall sleeve. The only exception is when an
RAD10 drain kit is installed to connect to an internal drain system. (See page 37 for RAD10 drain kit information.)
If the wall opening is greater than the sleeve dimensions, spacers must be used on the sides between the wall sleeve and the wall support structure to prevent distorting the wall sleeve.
3. Caulk or gasket the entire opening on the outside between the wall sleeve and exterior wall surface (four sides) to provide total water and air seal.
4. Caulk or gasket room-side opening between wall sleeve and interior wall surface (four sides). Openings beneath or around the wall sleeve 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 45 for maximum power cord length.
• Permanently connected units close to finished floor must allow for conduit clearance.
SLEEVE 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 sleeve, sleeve angles may be used. Sleeve angles are pieces of steel or other material of similar structural strength that are formed to a 90° angle, with holes to fasten the sleeve angle to the wall sleeve and to the structural component of the wall surrounding the wall sleeve.
The following describes the procedure when fieldfabricated and -installed sleeve angles are applied.
1. Position sleeve angles around top and sides of wall sleeve at the desired location. Position sleeve angles vertically on each side of wall sleeve to provide a level installation.
2. Mark wall sleeve through holes in sleeve angles. The lowest hole on the sides of the wall sleeve must be a minimum of 2" above the bottom of the sleeve.
3. For RAB71B wall sleeve, drill 5/32" diameter holes at locations marked on wall sleeve in Step 2, and assemble angles to wall sleeve using #10 x 1/2" selftapping screws. For RAB77B wall sleeve, follow the same procedure except use a #10 x 1/2" bolt, washer and nut to attach sleeve angles to sleeve. Install screws or bolts from inside wall sleeve.
4. Do not drill any holes in bottom of wall sleeve.
Do not distort wall sleeve.
5. Do not use sleeve angles for a lintel.

CONDENSATE DISPOSAL SYSTEMS
36
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 indoor coil. This water drains to a pan located under the indoor coil and is routed through the weather barrier or bulkhead (the partition 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
– where it 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. 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
AHRI (Air Conditioning, Heating & Refrigerating Institute) requires that all certified packaged terminal air conditioners and packaged terminal heat pumps pass a cooling condensate disposal test. One stipulation of the AHRI test is that under standard rating conditions “the equipment shall be started with its condensate collection pan filled to the overflowing point.” In order to pass the AHRI
Condensate Disposal Test the unit must operate continuously for four hours without condensed water dripping, running, or blowing off the unit 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 AHRI standards 310/380.
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 and 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 because the water would cause frost to form on the coil. This frost would block the airflow through the coil. Rather than allow this problem to occur, heat pump units must dispose of the condensate in another manner. The most widely used method of disposing of heat pump condensate is with a temperature-activated drain valve.
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 sleeve. The valve is fully open at approximately 45°F.
DRAIN KITS
Although the Zoneline units are designed to dissipate most 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 sleeve is objectionable, an internal or external drain system should be installed. See pages 37–38 for information covering the drain systems and the RAD10 kit available to connect to the wall sleeve.
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 sleeve, the installation of an internal or external drain system is recommended.
Units with ICR may not be installed in seacoast or other corrosive enivionment applications.
ICR model not compatible with RAKVENT1 kit and Makeup Air models.

DUCTED INSTALLATIONS
AZ45 AND AZ65 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 sleeve and a transition piece directs the air from the unit into the adapter duct.
Instructions for mounting the adapter to the wall sleeve 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 or damper installed in the discharge duct of the adapter is provided from the factory to provide approximately 70% air discharge into the primary room (room in which the unit is installed) and 30% into the secondary (adjacent) room.
Completely removing the discharge damper will result in approximately 80% air discharge into the primary room and
20% into the secondary room.
The installation of the wall sleeve 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 sleeve by 1" and the bracket and mounting screws add approximately 3/8" (3/16" on each side) to the width of the wall sleeve. If less than 1" of the wall sleeve projects into the room it will be necessary to allow for the additional width in the opening for the wall sleeve. The duct adapter mounting brackets should be mounted prior to installing the sleeve in the wall.
Refer to pages 40–41 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. Instructions for this modification are included with the duct adapter.

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. Turn the “Duct Mode” on in the auxiliary control settings (Mode 7). This increases the fan speed to ensure proper circulation.
4. Minimum recommended clearance between the unit and the adjacent wall is 2".
5. 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.
6. When calculating the heat gain/heat loss, take both areas into consideration.
7. Duct adapters are not for use on Dry Air 25 models or
Makeup Air models.
8. For best room temperature regulation, remote
thermostats should be used with Makeup Air models.
9. Heater wattages are reduced in duct mode
(see chart below).

The design of the Zoneline chassis has changed over the years to provide better performance and appearance, therefore, some of the components used in ducted applications have changed. Select the proper components from the information below. The best procedure in determining the correct kit is to measure the existing duct extension cross section.
Existing Duct Extension cross-section measurements:
8-3/8" H x 6-1/2" W (used prior to 1988)
Duct Adapter RAK7013 — This duct adapter will allow the replacement of a new chassis (AZ45 or AZ65 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
RAK7013 before removing and discarding the old duct adapter. (See notes on pages 51-52.)

GE Appliances in other colors. Minimum order quantities may be required. Contact your GE Appliances salesperson for details.
All grilles are installed and secured to the wall sleeve from the inside. Keyhole slots in the rear flange of the sleeve allow the grille to be placed in position before securing it firmly to the wall sleeve.
RAG60 Outdoor Grille — The standard exterior grille is made of durable aluminum to protect chassis components and prevent air recirculation.

Replacement of existing units: If an existing grille is not replaced, capacity and efficiency will be reduced and the unit may fail to operate properly or fail prematurely. If the existing grill is from 1992 to present and has deflectors, the RAK40 is not needed.
A deflector kit, RAK40, must be used with grilles that were not designed for current AZ Series
GE Appliances’ Zoneline ® units. 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. If RAK40 deflectors are used on the chassis, all old deflectors on the exterior grille must be removed. All grilles used with GE Appliances’ Zoneline units must comply with requirements of Exterior Architectural Treatments and Special Outdoor Grilles (See page 43).

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 Appliances 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 sleeve 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 sleeve, 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 protector and shorten compressor life. Using the unit with a grille that is too restrictive or allows recirculation may constitute improper installation and will void the unit's warranty.
A scale drawing of the louver section should be sent to GE Appliances 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 an independent lab to be tested with the
Zoneline unit.
Sample Calculations
Free Area (%) = xy x 100 x = 1" y = 1.5"
POWER CONNECTION FOR AZ45 AND AZ65 SERIES ZONELINE® UNITS
All AZ45 and AZ65 Series Zoneline units are equipped with universal heaters allowing chassis installation flexibility. The Zoneline units are connected to the building power supply by a unique power connection kit. By utilizing a separate universal power connection 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.
The appropriate kit is determined by the voltage, the means of electrical connection, either line-cord connected or permanently connected, and the desired resistance heat output that may be supported by the branch circuit.
230/208 VOLT
LINE CORD
CONNECTED UNITS
Line Cord Kits consist of a self-aligning four-pin molded connector that plugs into a mating connector on the
Zoneline chassis and insulated line cord with an electrical plug on the end.
FOUR PIN CONNECTOR
AND 20 AMP PERSONALITY PLUG
The configuration of the electrical plug conforms to Nation
Electrical Code (NEC) standards for the circuit amperage, and the configuration of the extra personality plug determines the heater wattage and current requirements when it is plugged into the Zoneline chassis. If the four pin connector does not have a personality plug (or the plug is not connected) the unit identifies it as a 15 amp circuit.
The power connection kit is selected by the amperage of the circuit where it will be installed. Each line cord kit has an integral Leakage Current Detection Interrupter (LCDI) or Arc Fault Current Interrupter (AFCI) device as required by the NEC and Underwriters Laboratory (UL) for line-cord connected air conditioners manufactured on or after August
1, 2004. The line-cord power connection kits are shown in the table below.

POWER CONNECTION FOR AZ45 AND AZ65 SERIES ZONELINE® UNITS
(CONTINUED)
230/208 VOLT PERMANENTLY
CONNECTED UNITS
Permanently connected units do not require the LCDI or AFCI device. Permanent connection is usually made through the use of a sub-base. Each 230/208 volt subbase consists of a sub-base with appropriate receptacle for minimum circuit amperage, a chaseway to route power connector from the sub-base to the chassis, wiring to connect the sub-base to building wiring and a short line cord with a self-aligning four-pin connector to connect to the chassis and plug into the receptacle in the sub-base.
Permanent, or direct-wired, installation of a 230/208 volt unit requires a junction box kit, RAK4002D, which attaches to the chassis to form an enclosed junction box.
The short sub-base line cord may not be used without the sub-base and junction box.
For AZ45 and AZ65 Series 230/208-volt units where a permanent installation using flexible conduit is desired, the RAK4002D forms an enclosed junction box on the chassis. The RAK4002D has a hole to allow a 1/2" trade size electrical conduit and a square knockout for the chaseway to be connected to the junction box. For direct connection, purchase and install the appropriate universal power supply kit (also referred to as the direct connection kit below) that matches the ampacity of the building circuit connected to the unit. This four-pin connector with three 7"-long conductor wires is used for direct connections to the building wiring inside a directconnect junction box.
These wires are then connected to the building wiring by field-supplied connectors.

265 OR 277 VOLT UNIT INSTALLATION — PERMANENTLY CONNECTED UNITS
NEC (Article 440.60) requires permanent connection for units connected to power sources over 250 volts; therefore these units must be permanently connected (direct-wired) with field-supplied connectors. Units connected using a sub-base meet the requirement for permanent connection since all wiring is internal wiring between the sub-base and the chassis and it is enclosed.
Since 265-volt units may not be line-cord connected, an LCDI device is not required.

ELECTRICAL WIRING INFORMATION
– AZ45/AZ65 SERIES
All Zonelines are single-phase 60-hertz units.
For all installations, the feeder, sub-feeder, branch circuit and electrical protective devices and selection must conform to the National Electrical Code (NEC) and to local codes.
Maximum connected load in amperes, including demands for the electric heater and the fan motor, are shown on pages 43–44. Branch circuit ampacity and electrical protective device sizing are shown on pages 43–44 for 230/208-volt and for 265-volt units.
More than one unit per branch circuit is not recommended. When in doubt, consult the NEC.
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 subbases since the unit was first introduced. Some of these changes require alterations to be made when replacing an older unit with a new chassis.

AZ65 SERIES SPECIFICATIONS
COOLING
Room air conditioner sizing is all about matching the room size to the air conditioner size. Since air conditioners remove both heat and humidity from the air, a unit that is too large, will cool the room before it has a chance to remove the humidity. The result will be a room that's not very comfortable – cool, but feeling damp and clammy.
Most musty odors in rooms are due to excess humidity.
Using a smaller-capacity unit or using Dry Air 25 units will provide better dehumidification. The largest factor in causing mold and mildew in the room is excess moisture.
A smaller unit running longer or a Dry Air 25 model can remove more moisture. Mold behind wall coverings that do not allow water vapor to pass through—vinyl wallpaper or oil-based paints, for example—is not a problem of excessive moisture in the room, but rather is caused by moisture trapped in the walls.
Since larger capacity units typically are louder, oversized air conditioners also create guest complaints due to the noise and short cycling.
HEATING
Using a resistance heater larger than required—using a 4.8 kW heater when a 3.4 kW heater would suffice, for example—may not cost any more in electrical consumption since the larger heater will operate, for less time. The “demand charge” portion of the utility bill—which is based on the highest electrical load for a period of time—may be a significant portion of the utility bill. Some customers have reported the demand charge actually being more than the usage charge. In a
100-room property it would be possible for the demand of the 4.8 kW heater versus a 3.4 kW heater to be 140 kW more than the demand charge if the lower wattage heaters were used. Working with the utility companies to understand their method of billing and taking advantage of any rebates they may offer can reduce the utility bill.
A heat load analysis should be performed to determine the heating and cooling load required for the space in question. How much heat is coming into the space that the air conditioner must remove and how much heat is lost during the winter months that must be replaced. The heat load analysis takes many factors into play, including cubic footage of space, location and construction type/ materials. Getting the right size means getting the comfort and the energy efficiency right.
KEY TERMS
Capacity - The capacity of an air conditioner is measured by the amount of cooling it can do when running continuously. The total capacity is the sum of the latent capacity (ability to remove moisture from the air) and sensible capacity (ability to reduce the dry-bulb temperature). Each of these capacities is rated in BTUs per hour (Btu/h).
Air conditioner capacity is rated per AHRI 310/380 conditions at 95°F drybulb and 75°F wetbulb outside with an inside temperature of 80°F drybulb and 67°F wetbulb.
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 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.)
Latent Cooling Load - The net amount of moisture added to the inside air by plants, people, cooking, infiltration, and any other moisture source. The amount of moisture in the air can be calculated from a combination of dry-bulb and wet-bulb temperature measurements.
Sensible Cooling Load - The heat gain of the room due to conduction, solar radiation, infiltration, appliances, people, and pets. Burning a light bulb, for example, adds only sensible load to the house. This sensible load raises the dry-bulb temperature.
Dry-bulb Temperature - The temperature measured by a standard thermometer.
Wet-bulb Temperature - When a wet wick is placed over a standard thermometer and air is blown across the surface, the water evaporates and cools the thermometer below the dry-bulb temperature. This cooler temperature
(called the wet-bulb temperature) depends on how much moisture is in the air.
EER - The Energy Efficiency Ratio is the efficiency of the air conditioner. It is capacity in BTUs per hour divided by the electrical input in watts.
ARCHITECTS & ENGINEERS DATA MANUAL AZ45/AZ65 SERIES
GENERAL INSTALLATION SUGGESTIONS
Many times poor or non-existent caulking around the exterior of the wall sleeve results in air infiltration, causing the unit to run excessively. One way to check for air infiltration is to look under and around the unit to the outdoors. If you can see light, there is air infiltration.
The first floor of a building is where this problem most frequently occurs since caulking the bottom of the wall sleeve may require lying outside in the dirt while working.
This has been the cause of many complaints about the
“short cycling” of the unit.
Curtains, furniture or other obstructions interfering with the discharge air circulation will make the unit cycle/turn off too soon since the cooled (or heated) discharge air is pulled back into the unit. This results in a room that is not adequately heated or cooled.
Blocking the discharge air on the unit during the heating operation can result in the unit overheating or shutting off prematurely. In some sleeves it is recommend that a “tent card” be used advising room occupants not to put anything on the unit.
ELECTRICAL WIRING INSTALLATION
Do not allow the installer to drill a hole in the wall sleeve to run the electrical wiring. If this is done, the wiring will have to be run between the chassis and the edge of the wall sleeve so it can be connected to the unit wiring on the room side of the wall sleeve. When the chassis is removed for servicing or cleaning, the insulation on the wires can be cut and can create a safety hazard.
If the electrical connection on a 230-volt or 208-volt installation is to be made by the line cord plugged into a wall-mounted receptacle, the receptacle should be located in the wall under the sleeve or close to the side of the wall sleeve. This installation makes a much neater appearance than a line cord running a foot or more across the floor.
The electrician may want to place the receptacle as far from the unit as possible to save a few feet of wiring without considering how the installation may appear.
CENTRAL DESK CONTROL AND REMOTE
THERMOSTAT WIRING
Do not allow the installer to drill a hole in the wall sleeve to run Central Desk Control (CDC) wiring or remote thermostat wiring to the unit terminals. CDC and remote thermostat wiring is classified as low-voltage wiring and does not have to be run in conduit unless required by local code. CDC and remote thermostat wiring should be run in the walls and exit the wall under the wall sleeve about 2" from the right-hand side. The base pan is designed with a clearance for the line cord and the low-voltage wiring can also be run to the chassis in this area. Wire molding can be used to hold the wiring close to the bottom of the wall sleeve.
If a sub-base is used, the wiring can be run through the sub-base, entering the rear and exiting through one of the front panels. When the room cabinet is in place, the CDC or remote thermostat wiring is usually not visible to someone standing or sitting in the room.
ARCHITECTS & ENGINEERS DATA MANUAL AZ45/AZ65 SERIES
Do not run the low-voltage wiring in conduits with line-voltage wiring or near uninsulated line-voltage wiring since induced current can interrupt the low-voltage controls.
Consult the electrical inspector early in the project, especially if the power to the air conditioner is to be 265 volts, to understand what is required to comply with local electrical codes.
WALL SLEEVE/EXTERIOR GRILLE
When making an installation where the exterior grille is flush with the exterior wall, or part of a custom window/ louver section, make sure the installer caulks the wall sleeve to the exterior wall, especially the bottom of the sleeve. Many times the air conditioners are run during construction and the building is not closed. This can result in excessive humidity from the warm humid air entering the building, or from the “drying out” of the building materials. Many problems have been caused by condensate water or rainwater running back into the building where proper caulking has not been done.
EXTERIOR GRILLES
When replacing an older unit, the existing outdoor grille may need to be changed or modified. Outdoor airflow patterns have changed and this may dictate the need for outdoor grille replacement or modification.
If using an existing non-GE exterior grille, special attention must be paid to ensuring the air deflectors are in the proper locations on the exterior grille. Otherwise they should be removed and replaced with new RAK40 deflectors on the back of the chassis.
NOTE: Heater wattages are reduced in duct mode (see page 39).
DUCTED INSTALLATION COMMENTS
Anytime a duct extension is used, it is required to go into the auxiliary controls and turn on the duct mode feature.
This will boost the fan speeds to allow for proper air circulation for ducted applications.
NOTE: Heater wattages are reduced in duct mode
(see page 39).
NEW INSTALLATIONS
The GE Zoneline® AZ45 and AZ65 Series are approved for ducted installation using the GE Duct Adapter model
RAK6053 and the GE Duct Extension RAK601B. A field-fabricated duct extension with the same interior measurements as the RAK601B may be used with the
RAK6053 duct adapter. GE does not allow ducting in more than one direction.
The use of a duct adapter other than the RAK6053 is not approved by GE Appliances and may cause problems such as inadequate airflow to the secondary room or the unit shutting off on one of the overload devices.
Failure to allow for adequate air return from the secondary room is often the cause of less than satisfactory performance of a ducted installation.

REPLACEMENT INSTALLATIONS
GE offers duct adapters to allow for easy replacements of previous-design chassis in ducted installations where a GE duct adapter was used in the original installation.
A duct adapter is available that will align with the duct extension when GE-built components were used in the original installation.
The duct adapter/extension used from the early 1960s until late 1987 was 8-3/8" high by 6-1/2" wide . If the chassis to be replaced uses this size duct, use the duct adapter model RAK7013 with the new product to match up to the existing duct extension. This means the duct extension will not have to be changed.
However, to keep the cost of the replacement to a minimum there are components that will need to be taken off the existing installation and reused on the
RAK7013 duct adapter. Therefore, save all parts from the existing setup until after the installation is complete.
It is important that those parts not be discarded until the new installation is complete.
If the existing duct dimensions are 7-3/32" high by 6-1/2" wide , the RAK7023 transition piece is required to install an AZ45 or AZ65 Series unit in the ducted installation.
There were a number of Zoneline units installed in ducted installations that did not use a GE duct adapter.
The easiest way to determine if the existing duct adapter is a GE duct adapter is to compare the duct adapter dimensions to the dimensions above. If the dimensions are different from the dimensions above or if the duct adapter is not made of sheet metal, it is not a GE duct adapter.
In such installations, GE recommends the removal of the old duct adapter and duct extension and the installation of a RAK6053 duct adapter and a RAK601B duct extension. Zoneline units installed in installations not using GE duct adapters and an extension with the same cross-section dimensions as the duct adapter may not be covered by the warranty.

POWER CONNECTION KITS ARE REQUIRED ON ALL ZONELINE CHASSIS (SEE CHART BELOW).
The correct kit for the installation is determined by the voltage and amperage of the electrical circuit and the means of connecting the unit to the building wiring.
Zoneline connection kits now come with “personality plugs.” The black connector carries the power to the unit, but the extra wiring and connector attached to the plug determine the wattage of the heater to be engaged (which should match the breaker feeding the unit). Kits without a personality connector (or if connector is not plugged in) will provide the 15 amp heater values described below. The two-wire connector is for a 20 amp circuit and the four-wire connector is for the 30 amp circuit.
If the unit is to be plugged into a receptacle, a line-cord kit would be used; if the unit is to be permanently connected, a permanent- connection kit would be used. 265 volt cord set units must be installed in compliance with National Electrical Code ® .
