IMPORTANT
The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians. Any
heat pump is more critical of proper operating, charge and an
adequate duct system than a straight air conditioning unit. All
duct work supply and return, must be properly sized for the
design air flow requirement of the equipment. ACCA is an
excellent guide to proper sizing. All duct werk or portions
thereof not in the conditioned space should be properly
insulated in order to both conserve energy and prevent
condensation or moisture damage.
SHIPPING DAMAGE
Upon receipt of equipment, the carton should be checked for
external signs of shipping damage. if damage is found, the
receiving party must contact the last carrier immediately,
preferably in writing, requesting inspection by the carrier's
agent.
GENERAL
The refrigerant system is complately assembled and charged.
All internal wiring is complete,
The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.
These instructions explain the recommended method to install
the air cooled self-contained unit and the electrical wiring
connections to the unit,
These instructions and any instructions packaged with any
separate equipment required to make up the entire air
conditioning system should be carefully read before beginning
the installation. Note particularly "Starting Procedure" and any
tags and/or labels attached to the equipment,
While these instructions are intended as a general recommended
guide, they dc not supersede any national and/or local codes
in any way. Authorities having jurisdiction should be consulted
before the installation is made.
INSTALLATION
Size of unit far a proposed installation should be based on
heat loss calculation made according to methods of Air
Conditioning Contractors of America {ACCA). The air duct
should be installed in accordance with the Standards of the
National Fire Protection Association for the Installation of Air
Conditioning and Ventilating systems of Other Than Residence
Type, NFPA No. 90A, and Residence Type Warm Air Heating
and Air Conditioning Systems, NFPA No. 908. Where local
regulations are at a variance with instructions, installer should
adhere to local codes,
DUCT WORK
Design the duct work according to methods given by the Air
Conditloning Contractors of America. When duct runs through
unheated spaces, it should be insulated with a minimum of one
inch of insulation. Use insulation with a vapor barrier on the
outside of the insulation. Flexible joints should be used to
connect the duct werk to the equipment in order to keep the
noise transmission to a minimum.
A one-inch clearance to combustible material for the first three
feet of duct attached to the outlet air frame is required. See
page 5 for further details.
FILTER
A one inch throwaway filter is supplied with each unit. The
filter slides into position making it easy to service. This filter
can be serviced from the outside by removing the service
door,
FRESH AIR INTAKE
All units are built with a fresh air inlet hole punched in the
service panel. The fresh air damper assembly is shipped with
each unit, and must be attached at the installation site. See
Figure 1 for typical installation procedure.
The fresh air damper assembly Is standard equipment with the
unit because of the variety of state or local codes requiring
fresh air capability.
All capacity, efficiency and cost of operation information as
required for Department of Energy "Energyguide" Fact Sheets
is based upon the fresh air blank-off plate in place and is
recommended for maximum energy efficiency.
The blank-off plate is available upon request from the factory
and is installed in place of the fresh air damper shipped with
each unit.
WALL MOUNTING
1. Two holes, the size of the supply and return air openings
must be cut through the wall as shown in Figure 2.
2. On wood-frame wails, the wall construction must be strong
and rigid enough to carry the weight of the unit without
transmitting any unit vibration.
3. Concrete block walls must be thoroughly inspected to
insure that they are capable of carrying the weight of the
installing unit.
4. Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the
wall cavity.
5. Some instailations may not require any return air duct. It
is recommended that on this type of installation that a
filter grille be located in the wali. Fiiters must be of
sufficient size to allow a maximum velocity of 400 FPM.
NOTE: If no return air duct is used, applicable installation
codes may limit this cabinet to installation oniy in a
single story structure,
WIRING - MAIN POWER
Refer to the unit rating plate for wire sizing information and
maximum fuse or "HACR Type" circuit breaker size. Each
outdoor unit is marked with a "Minimum Circuit Ampacity,"
This means that the field wiring used must be sized to carry
that amount of current. Depending con the installed Kw of
electric heat, there may be two field power circuits required,
If this is the case, the unit serial plate wilt so indicate. Some
models are suitable only for connection with copper wire, while
others can be wired with either copper or aluminum wire. Each
unit and/or wiring diagratn will be marked "Use Copper
Conductors Only" or "Use Copper or Aluminum Conductors."
These instructions MUST BE adhered ta. Refer to the National
Electricat Code for complete current carrying capacity data on
the various insulation grades of wiring material.
The electrical data lists fuse and wire sizes (60°F copper) for
all models, including the most commonly used heater sizes.
Also shown are the number of field power circuits required for
the various models with heaters,
uu
The unit rating piate lists a "Maximum Time Delay Relay Fuse"
or "HACR Type" circuit breaker that is to be used with the
equipment. The correct size must be used for proper circuit
protection and also to assure that there will be no nuisance
tripping due to the momentary high starting current of the
compressor motor.
WIRING - 24Y CONTROL CIRCUIT
Nine (9) wires should be run from thermostat subbase to the
24V terminal board in the unit. A nine conductor, 18 gauge
copper, color-coded thermostat cable is recommended. The
connection points are shown on most of the wiring diagrams
and are also shown below.

Unit 24V Terminal Board
IMPORTANT NOTE: Only the thermostat and subbase
combinations as shown above will work with this equipment.
The stat and subbase MUST be matched, and correct operation
can be assured only by proper selection and application of
these paris.
CONDENSATE DRAIN
A plastic drain hose extends from the drain pan at the top of
the unit down to the unit base, There are openings in the unit
base for the drain hose to pass through. In the event the
drain hose is connected to a drain system of some type, it
must be an open or vented type system to assure proper
drainage.
COMPRESSOR MALFUNCTION RELAY (Single Phase Models Oniy)
Actuation of the green “check” lamp is accomplished by a
voltage type relay which is factory installed. Any condition
such as loss of charge, defective capacitor, defective
contactor, etc., that will prevent compressor from operating
will cause green lamp to activate. This is a signal to the
operator of the equipment to place system in emergency heat
position.
PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all units
so that the system operating pressures can be observed.
Pressure curves can be found later in the manual covering all
models on both cooling and heating cycles. It is imperative to
match the correct pressura curve to the unit by model
number.
SEQUENCE OF OPERATION
Cooling - Circuit R-Y makes at thermostat pulling in
compressor contactor, starting the compressor and outdoor
motor. The G (indoor motor) circuit is automatically completed
on any call for cooling operation, or can be energized by
manual fan switch on subbase for constant air circulation.
Heating - A 24V solenoid coil on reversing valve controls
heating cycle operation. Two thermostat options, one allowing
"Auto" changeover fram cycie to cycle and the other constantly
energizing solenoid coil during heating season and thus
eliminating pressure equalization noise except during defrost,
are to be used, On "Auto" option, a circuit is completed from
R-Wi and R-Y on each heating "on" cycle, energizing
reversing valve solenoid and pulling in compressor contactor
starting compressor and outdoor motor. R-G also make starting
indoor blower motor. Heat pump heating cycle now in
operation. The second option has no "Auto" changeover
position, but instead energizes the reversing valve solenoid
constantly whenever the system switch on subbasa is placed In
"Heat" position, the "8" terminal being constantly energized
from R. A thermostat demand for heat completes R-Y circuit,
pulling Im compressor contactor starting compressor and
outdoor motor. R-G also make starting indoor blower motor.
COMPRESSOR CUT-OFF THERMOSTAT £ OUTDOOR THERMOSTATS
Heat pump compressor operation at outdoor temperatures below
0°F are neither desirable nor advantageous in terms of
efficiency. Since most equipment at time of manufacture is not
designated for any specific destination of the country, and
most of the equipment is installed in areas not approaching the
lower outdoor temperature range, the compressor cut-offs are
not factory installed.
Outdoor thermostats are available to hoid off various banks of
electric heat until needed as determined by outdoor
temperature. Tha set point of either type of thermostat is
variable with geographic region and sizing of the heating
equipment to the structure. Utilization of the Heating
Application Data and the heat loss calculation of the building
are useful in determining the correct set points.
COMPRESSOR CUT-OFF AND OUTDOOR THERMOSTAT WIRING
See specific wiring information on pages.
HEAT ANTICIPATION
Both of the thermostats shown below have a fixed heat
anticipator for stage 1 with no adjustment required. Stage 1
has an adjustable anticipator for the W2 connection and fixed
for the Wi connection. Both the W2 and W3 circuits are
controlled by the stage 2 bulb. The only heat anticipator that
needs to be checked is stage 2 and it should be set to match
the load carried by the W2 circuit. The normal factory wiring
provides for only one electric heat contactor to be controlled
by W2, and the anticipator should be set at .4#0A. If special
field wiring is done, it is best to actuaily measure the load but
a good rule is .40A for each heat contactor controlied by W2,

cycle}. No pressure equalization noise when thermostat is
satisfied on either heating or cooling.
e Allows thermostat to control both heating and cooling
operation when set in "AUTO" position. Reversing valve
de-energizes at end of each "ON" heating cycle.
IMPORTANT NOTE: Both thermostat and subbase combinations
shown above incorporate the following features: Man-Auto fan
switch, Off-Heat-Cool-Em. Heat Switch, and two (2) indicator
lamps—one for emergency heat and one for compressor
malfunction.
THERMOSTAT INDICATOR LAMPS
The red lamp marked “EM.HT." comes on and stays on
whenever the system switch is placed in the emergency heat
position. The green lamp marked “check” will come on if there
is any problem that prevents the compressor from running
when it is supposed to be.
EMERGENCY HEAT POSITION
The operator of the equipment must manually place the system
switch in this position. This is done when there is a known
problem with the indoor section, or when the green "check"
lamp comes on indicating a problem.
DEFROST CYCLE
The defrost cycle is controlled by time and temperature. The
24 volt timer motor runs all the time the compressor is in
operation. When the outdoor temperature is in the lower 40°F
temperature range or colder, the outdoor coil temperature is
32°F or below, This temperature is sensed by the defrost
thermostat mounted near the bottom of the outdoor coil on a
return bend. The defrost thermostat closes at approximately
32°F. Every 60 (or 30) minutes that the compressor is
running, contacts 3-5 close for 7 minutes, with contacts 3-4
closed for the first 430 seconds of that 7 minutes. If the
defrast thermostat is closed, the defrost relay energizes and
places the system in defrost mode. An interlocking circuit is
created with timer contacts 3-5 and defrost relay contacts 7-9
in series.
During the defrost mode, the refrigerant cycle switches back
to the cooling cycle, the outdoor motor stops. electric heaters
are energized, and hot gas passing through the outdoor coil
melts any accumulated frost. When the temperature rises to
approximately 51°F, the defrost thermostat opens,
de-energizing the defrost relay and returning the system to
heating operation.
If some abnormal or temporary condition such as a high wind
causes the heat pump to have a prolonged defrost cycle,
contacts 3-5 of the defrost timer will open after 7 minutes and
restore the system to heating operations automatically.
There are two time settings on the defrost timer--30 minutes
and 60 minutes. Most models are shipped wired on the 60
minute setting for greatest operating economy. If special
Circumstances require a change to the shorter time, remove
wire connected to terminal 5/60 and reconnect to terminal 5/30.
There is a manual advance knab located on the timer. This can
be used to advance timer to contact closure point if it is
desired to check out defrost cycle operation, without waiting
for time to elapse.
DEFROST TIMER WIRING
See
Note
NOTE: All models are connected to 5/60 terminal (60 minute).
Any model can be changed from 60 minutes to 30
minutes by unplugging from 5/60 terminal and
reconnecting to 5/30 terminal as shown by dotted line.
SERVICE HINTS
1. Caution homeowner to maintain clean air fiiters at all times.
Also, not to needlessly close off supply and return air
registers. This reduces air flow through the system, which
shortens equipment service life as well as increasing
operating costs.
Z. Switching to heating cycle at 75°F or higher outside
temperature may cause 8 nuisance trip of the manual reset
high pressures switch.
3. The heat pump wall thermostats perform multiple functions.
Be sure that all function switches are correctly set for the
desired opsrating mode before trying to diagnose any
reported service problems.
4. Check all power fuses or circuit breakers to bs sure that
they are the correct rating.
5. Periodic cleaning of the outdoor coil to permit full and
unrestrictad airflow circulation is essential.
IMPORTANT INSTALLER NOTE
For improved start-up performance wash the indoor coil with a
dishwasher detergent.
CRANKCASE HEATERS
All units are provided with some form of compressor crankcase
heat. Some single phase units utilize the compressor motor
start winding in series with a portion of the run capacitor to
generate heat within the compressor shell to prevent liquid
refrigerant migration,
Some three phase units utilize a wraparound type of crankcase
heater that warms the compressor oil from the outside.
Some single and three phase models have an insertion well-type
heater located in the lower section of the compressor housing.
This is a seif-regulating type heater that draws only enough
Power to maintain the compressor at a safe temperatura.
Some form of crankcase heat is essential to prevent liquid
refrigerant from migrating to the compressor, causing oil pump
out on compressor start-up and possible valve failure due to
compressing a liquid.
Refer to unit wiring diagram to find exact type of crankcasa
heater used.
The following decal is affixed to ail outdoor units detaiiing
start-up procedure. This is very important, Please read
carefully.
