@ These “minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National
Electric Code (latest revision), article 310 for powar conductor sizing. CAUTION. When more than one field power
conductor circuit is run thru one conduit, the conductors must be derated. Pay special attention to note 8 of table 310
regarding Ampacity Adjustment Factors when more than 3 conductors are in a raceway.
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 camer immediately,
preferably in writing, requesting inspection by the carrier’s
agent.
GENERAL
The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians.
The refrigerant system is completely assembied 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 do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made. See Page 1 for information on codes and standards.
Size of unit for 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 instalied 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. 90B. Where local regulations are at a variance with
instructions, installer should adhere to local codes.
DUCT WORK
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.
Air Conditioning Contractors of America (ACCA) is an
excellent guide to proper sizing. All duct work or portions
thereof not in the conditioned space should be properly
insulated in order to both conserve energy and prevent
condensation or moisture damage.
Manual
Page 4
2100-347
Design the duct work according to methods given by the Air
Conditioning Contractors of America (ACCA). When duct
runs through unheated spaces, it should be insulated with a
minimum of one inch of insulation. Use insulation with a
vapor bamer on the outside of the insulation. Fiexible joints
should be used to connect the duct work to the equipment in
order to keep the noise transmission to a minimum.
A 1/4 inch clearance to combustible material for the first
three feet of duct attached to the outlet air frame is required.
See Wall Mounting Instructions and Figures 3 and 3A for
further details.
Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the wall
cavity.
Some installations may not require any return ajr duct. A
metallic return air grille is required with installations not
requinng a return air duct. The spacing between louvers on
the grille shall not be larger than 5/8 inch.
NOTE: If no return air duct is used, applicable installation
codes may limit this cabinet to installation only in
a single story structure.
Any grille that meets with 5/8 inch louver criteria may be
used. It is recommended that Bard Return Air Grille Kit
RG2 through RGS or RFG2 through RFGS be installed
when no return duct is used. Contact distributor or factory
for ordering information. If using a return air filter grille,
filters must be of sufficient size to allow a maximum
velocity of 400 fpm.
FILTERS
À 1 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. A 1 inch washable filter and a 2 inch pleated
filter are also available as optional accessories. The internal
filter brackets are adjustable to accommodate the 2 inch
filter by bending down the two horizontal tabs on each filter
bracket.
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in the
service panel.
If the unit is equipped with a fresh air damper assembly, the
assembly is shipped already attached to the unit. The
damper blade 1s locked in the closed position. To allow the
damper to operate, the maximum and minimum blade
position stops must be installed. See Figure 2.
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 1s 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.

CONDENSATE DRAIN - EVAPORATOR
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.
CONDENSATE DRAIN - CONDENSER
A hole 1s provided in the unit base to accept a Drain
Connection Kit 8620-160. This allows connection of the
unit base pan to a drain if so desired. (See Figure 3 and
instructions provided with the 8620-160 kit.) 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.

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”. Thus means that the field wiring used must be
sized to carry that amount of current. Depending on the
installed KW of electric heat, there may be two field power
circuits required. If this is the case, the unit serial plate will
so indicate. All models are suitable only for connection
with copper wire. Each unit and/or wiring diagram will be
marked “Use Copper Conductors Only”. These instructions
must be adhered to. Refer to the National Electrical Code
(NEC) for complete current carrying capacity data on the
various insulation grades of wiring maternal. All wiring
muse conform to NEC and all local codes.
The electrical data lists fuse and wire sizes (75° C copper)
for all models inciuding the most commonly used heater
sizes. Also shown are the number of field power circuits
required for the various models with heaters.
The unit rating plate 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.
The disconnect access door on this unit may be locked to
prevent unauthorized access to the disconnect. To convert
for the locking capability, bend the tab locate in the bottom
left hand comer of the disconnect opening under the
disconnect access panel straight out. This tab will now line
up with the slot in the door. When shut a padlock may be
placed through the hole in the tab preventing entry.
See “Start Up” section for important information on three
phase scroll compressor start ups.
WIRING —- LOW VOLTAGE WIRING
230 / 208V, 1 phase and 3 phase equipment dual primary
voltage transformers. All equipment leaves the factory wired
on 240V tap. For 208V operation, reconnect from 240V to
208V tap. The acceptable operating voltage range for the
240 and 208V taps are:
TAP RANGE
240 253 - 216
208 220 — 187
NOTE: The voltage should be measured at the field
power connection point in the unit and while the
unit is operating at full load (maximum amperage
operating condition).
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 1s recommended. The
connection points are shown in Figure 8:

L OUTDOOR THERMOSTAT USED MIS-409
AS COMPRESSOR CUTOFF
COMPRESSOR CUT OFF THERMOSTAT AND
QUTDOOR THERMOSTATS
Heat pump compressor operation at outdoor temperatures
below 0° F are neither desirabie 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 hold off various banks
of electric heat until needed as determined by outdoor
temperature. The set point of either type of thermostat is
variable with geographic region and sizing of the heating
equipment to the structure. See Figures 9 and 10. Utilization
of the Heating Application Data and the heat loss calculation
of the building are useful in determining the correct set
points.
HEAT ANTICIPATION
All of the thermostats shown in Table 4 have a fixed heat
anticipator for stage 1 with no adjustment required. Stage 2
has an adjustable anticipator of the W2 connection and fixed
for the W3 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 .40A.
If special field wiring is done, it is best to acutually measure
the load but a good rule is .40A for each heat contactor
controled by W2.
THERMOSTAT INDICATOR LAMPS
The red lamp marked “Em. Ht.” comes on and stays on
whenever the system switch 1s 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.
Manual 2100-347
Page 13
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 unit, or when the green “check”
lamp comes on indicating a problem.
COMPRESSOR MALFUNCTION LIGHT
Actuation of the green “check” lamp is accomplished by a
relay output from the heat pump control board which is
factory installed. Any condition such as loss of charge, high
head pressure, etc., that will prevent compressor from
operating will cause the green lamp to activate. This is a
signal to the operator of the equipment to place system in
emergency heat position.

START UP
IMPORTANT INSTALLER NOTE
For improved start up performance wash the indoor coil
with a dish washing detergent.
CRANKCASE HEATERS
WH611-B and -C are provided with compressor crankcase
heat. All other models are not provided with crankcase
heat. They are either single phase or the system refrigerant
charge is not of sufficient quantity to require crankcase heat.
The WH611-B and -C models have a wrap around type
heater located on the lower section of the compressor
housing. This is an on/off heater that is controlled by the
compressor contactor.
The label in Figure 11 is affixed to all WH611-B and -C
units detailing start up procedure. This is very important.
Please read carefully.
HIGH PRESSURE SWITCH
All models are supplied with a remote reset high pressure
switch. If tripped, this pressure switch may be reset by
turning the thermostat off then back on again.
TWO SPEED OUTDOOR FAN MOTORS
All units have two speed outdoor fan motors.
The two speed outdoor fan motor is controlled with an
outdoor thermostat and operates on low speed below 80° F
outdoor temperature in cooling mode. In heating mode it
operates on high speed only.
THREE PHASE SCROLL COMPRESSOR
START UP INFORMATION
Scroll compressors, like several other types of compressors,
will only compress in one rotational direction. Direction of
rotation is not an issue with single phase compressors since
they will always start and run in the proper direction.
However, three phase compressors will rotate in either
direction depending upon phasing of the power. Since there
is a 50-50 chance of connecting power in such a way as to
cause rotation in the reverse direction, verification of proper
rotation must be made. All three phase units incorporate a
phase monitor to ensure proper field wiring. See the “Phase
Monitor” section later in this manual.
Verification of proper rotation must be made any time a
compressor is changed or rewired. If improper rotation is
corrected at this time there will be no negative impact on the
durability of the compressor. However, reverse operation for
over one hour may have a negative impact on the bearing
due to oil pump out.
NOTE: If compressor is allowed to run in reverse
rotation for several minutes, the compressor's
internal protector will trip.

THESE PROCEDURES MUST BE
FOLLOWED AT INITIAL START
UP AND AT ANY TIME POWER
HAS BEEN REMOVED FOR 12
HOURS OR LONGER.
TO PREVENT COMPRESSOR DAMAGE
WHICH MAY RESULT FROM THE
PRESENCE OF LIQUID REFRIGERANT
IN THE COMPRESSOR CRANKCASE:
1. MAKE CERTAIN THE ROOM THERMO-
STAT IS IN THE “OFF* POSITION. (THE
COMPRESSOR IS NOT TO OPERATE.)
2. APPLY POWER BY CLOSING THE SYS-
TEM DISCONNECT SWITCH. THIS
ENERGIZES THE COMPRESSOR
HEATER WHICH EVAPORATES THE
LIQUID REFRIGERANT IN THE CRANK-
CASE.
3. ALLOW 4 HOURS OR 60 MINUTES PER
POUND OF REFRIGERANT {N THE SYS-
TEM AS NOTED ON THE UNIT RATING
PLATE, WHICHEVER IS GREATER.
4. AFTER PROPER ELAPSED TIME THE
THERMOSTAT MAY BE SET TO OPER-
ATE THE COMPRESSOR.
5. EXCEPT AS REQUIRED FOR SAFETY
WHILE SERVICING, DO NOT OPEN
SYSTEM DISCONNECT SWITCH.
7961-411
All three phase ZR3 compressors are wired identically
intemally. As a result, once the correct phasing is
determined for a specific system or installation, connecting
properly phased power leads to the same Fusite terminal
should maintain proper rotation direction.
Verification of proper rotation direction is made by
observing that suction pressure drops and discharge pressure
rises when the compressor is energized. Reverse rotation
also results in an elevated sound level over that with correct
rotations, as well as, substantially reduced current draw
compared to tabulate values.
The direction of rotation of the compressor may be changed
by reversing any two line connections to the unit.
Manual 2100-347
Page 15
PHASE MONITOR
All units with three phase compressors are equipped with a
3 phase line monitor to prevent compressor damage due to
phase reversal.
The phase monitor in this unit is equipped with two LEDs.
If the Y signal is present at the phase monitor and phases
are correct, the green LED will light. If phases are reversed,
the red fault LED will be lit and compressor operation is
inhibited.
If a fault condition occurs, reverse two of the supply leads to
the unit. Do not reverse any of the unit factory wires as
damage may occur.
SERVICE HINTS
1. Caution homeowner to maintain clean air filters 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.
2. Switching to heating cycle at 75° F or higher outside
temperature may cause a nuisance trip of the remote
reset high pressure switch. Turn thermostat off then on
to reset the high pressure switch.
3. The heat pump wall thermostats perform multiple
functions. Be sure that all function switches are correctly
set for the destred operating mode before trying to
diagnose any reported service problems.
4, Check all power fuses or circuit breakers to be sure they
are the correct rating.
5. Periodic cleaning of the outdoor coil to permit full and
unrestricted airflow circulation is essential.
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 of constant air
circulation.
HEATING ~ A 24V solenoid coil on reversing valve
controls heating cycle operation. Two thermostat options,
one allowing “Auto” changeover from cycle 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-W1 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 subbase is placed in “Heat” position, the “B”
terminal being constantly energized from R. A thermostat
demand for heat completes R-Y circuit, pulling in
compressor contactor starting compressor and outdoor
motor. R-G also make starting indoor blower motor.
PRESSURE SERVICE PORTS
High and Low pressure service ports are installed on all
units so that the system operating pressures can be observed.
Pressure tables can be found later in the manual covering all
models on both cooling and heating cycles. It is imperative
to match the correct pressure table to the unit by model
number.
DEFROST CYCLE
The defrost cycle is controlled by temperature and time on
the solid state heat pump control
When the outdoor temperature is in the lower 40° F
temperature range or colder, the outdoor coil temperature is
32° F or below. This coil temperature is sensed by the coil
sensor mounted near the bottom of the outdoor coil. Once
coil temperature reaches 30° F or below, the coil sends a
signal to the control logic of the heat pump control and the
defrost timer will start.
After 60 (90 or 30) minutes at 30° F or below, the heat
pump control will place the system in the defrost mode.
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 nses to
approximately 57° F the coil sensor will send a signal to the
heat pump control which will return the system-to-heating
operations automatically.
If some abnormal or temporary condition such as a high
wind causes the heat pump to have a prolonged defrost
cycle, the heat pump controi will restore the system to
heating operation automatically after 10 minutes.
There are three settings on the heat pump control — 30
minutes, 60 minutes, and 90 minutes. Most models are
shipped wired on the 60 minute setting for greatest
operating economy. If special circumstances require a
change to another time, remove wire connected to terminal
60 and reconnect to desired terminal.
There is a cycle speed up jumper on the control. This can be
used to reduce the time between defrost cycle operation
without waiting for ume to elapse.
There is an initial defrost (INIT. DEF.) jumper on the
control than can be used at any outdoor ambient dunng the
heating cycle to simulate a 0° coil temperature. See
Figure 12. This can be used to check defrost operation of the
unit without waiting for the outdoor ambient to fall into the
defrost region.
