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 equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.
The refrigerant system is completely 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 and any instructions packaged with
any separate equipment required to make up the entire
heat pump 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 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. 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) 1s 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.
Refer to Table 10 for maximum static pressure available
for duct design.
Design the duct work according to methods given by the
Air Conditioning Contractors of America (ACCA).
When duct runs through unheated spaces, 1t 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 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 (3') of duct attached to the outlet air
frame is required. See Wall Mounting Instructions and
Figures 3, 4, 5, and 6 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.
A CAUTION
Some installations may not require any return
air duct. A metallic return air grille is required
with installations not requiring a retum air duct.
The spacing between louvers on the grille shall
not be larger than 5/8 inches.
Any grille that meets the 5/8 inch louver criteria, may be
used. It 1s recommended that Bard Retum Air Grille Kit
RG-2 thru RG-5 or RFG-2 thru RFG-5 be installed
when no return duct is used. Contact distributor or
factory for ordering information. If using a return air
filter gnlle, filters 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 lirnit this cabinet to
installation only in a single story structure.
FILTERS
A 1 inch throwaway filter is supplied with each unit.
The filter shdes 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 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 tabs
to allow spacing for the 2 inch filters.
Manual 2100-357
Page 5
FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in
the service panel.
If the unit is equipped with the 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 minium 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 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.
CONDENSATE DRAIN
À 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.

INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
1. Two holes, for the supply and return air openings,
must be cut through the wall as shown in Figure 3.
2. On wood-frame walls, the wall construction must be
strong and rigid enough to carry the weight of the
unit without transmitting any unit vibration. See
Figures 5 and 6.
AWARNING
Fire hazard can result if 1/4 inch clearance to
combustible materials for supply air duct is not
maintained. See Figure 3.
3. Concrete block walls must be thoroughly inspected to
insure that they are capable of carrying the weight of
the installing unit. See Figure 5.
MOUNTING THE UNIT
1. These units are secured by wall mounting brackets
which secure the unit to the outside wall surface at
both sides. A bottom mounting bracket is provided
for ease of installation, but it is not required.
2. The unit itself is suitable for “0” inch clearance, but
the supply air duct flange and the first 3 feet of
supply air duct require a minimum of 1/4 inch
clearance to combustible matenal. If a combustible
wall, use a minimum of 28-1/2" x 8 -1/2" dimensions
for sizing. However, it is generally recommended
that a 1 inch clearance is used for ease of installation
and maintaining the required clearance to
combustible material. The supply air opening would
then be 30" x 10". See Figures 3, 4 and 6 for details.
AWARNING
Failure to provide the 1/4 inch clearance
between the supply duct and a combustible
surface for the first 3 feet of duct can result in
tire.
3. Locate and mark lag bolt locations and bottom
mounting bracket location, if desired. See Figure 5.
4. Mount bottom mounting bracket, if used.
5. Hook top rain flashing under back bend of top. Top
rain flashing is shipped secured to the right side of
the back.
6. Position unit in opening and secure with 5/16 lag
bolts; use 3/4 inch diameter flat washers on the lag
bolts.
7. Secure rain flashing to wall and caulk across entire
length of top. See Figure 3.
8. For additional mounting rigidity, the return air and
supply air frames or collars can be drilled and
screwed or welded to the structural wall itself
(depending upon wall construction). Be sure to
observe required clearance if combustible wall.
9. On side by side installations, maintain a minimum of
20 inches clearance on right side to allow access to
heat strips and control panel, and to allow proper
airflow to the outdoor coil. Additional clearance may
be required to meet local or national codes.

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 on the installed KW of electric
heat, there may be two field power circuits required. If
this 1s 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 material. All wiring must conform to NEC and
all local codes.
The electrical data lists fuse and wire sizes (75°C
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.
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 tnpping due to the
momentary high starting current of the compressor

THERMOSTAT INDICATOR LAMPS
The red lamp will come on if there is any problem that
prevents the compressor from running when it is
supposed to be.
EMERGENCY HEAT MODE
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 red lamp
comes on indicating a problem.
COMPRESSOR MALFUNCTION LIGHT
Actuation of the red 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 operation will cause red 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 dishwashing detergent.
CRANKCASE HEATERS
All units are provided with some form of compressor
crankcase heat.
All single and three phase models have an insertion
well-type heater located in the lower section of the
compressor housing. This is a self-regulating type
heater that draws only enough power to maintain the
compressor at a safe temperature.
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.
The decal in Figure 10 is affixed to all outdoor units
detailing start-up procedure. This is very important.
Please read carefully.
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 desired operating mode before
trying to diagnose any reported service problems.
4. Check all power fuses or circuit breakers to be sure
they are the cotrect 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 for 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, Фе "В"
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,

OCCUPIED MODE
VENTILATION SEQUENCE — The ERV and indoor
blower will be continuously energized when the timer is
energized.
COOLING SEQUENCE - On a call for cooling, the
compressor of the unit is energized to provide cooling.
A call for cooling cancels dehumidification mode.
Cooling mode is only available when the timer is
energized.
HEATING SEQUENCE -- Onacall for heating, the
compressor and-reversing valve of the unit are
energized to provide heat pump heating. If the room
temperature falls below the 2nd stage heating set point
backup electric heat is energized. Heat pump heating is
only available when the timer is energized. If heating is
energized any call for dehumidification is ignored. If
dehumidification is already energized a call for 2nd
stage heating is needed to cancel dehumidification
mode.
DEHUMIDIFICATION SEQUENCE - Onacall for
dehurmdification the compressor and three way valve of
the unit are energized to provide dehumidification.
Dehumidification mode will continue until the
humidistat is satisfied. If the room temperature falls
below lst stage heating setpoint, electric heat will be
energized by the room thermostat and cycle to maintain
room temperature. If 2nd stage heating setpoint is
reached, dehumidification is de-energized and heat
pump heating is energized. A call for cooling cancels
dehumidification mode.
UNOCCUPIED MODE
Cooling, heating, emergency heat and ventilation are
inhibited.
DEHUMIDIFICATION SEQUENCE — On a call for
dehumidification the compressor and three way valve of
the unit are energized to provide dehumidification.
Dehumidification mode will continue until the
humidistat is satisfied. If the room temperature falls
below 65 degrees and dehumidification 1s energized,
electric heat wiil be energized by the return air
thermostat and cycle to maintain room temperature.
OTHER CONTROL SEQUENCE
Any time the indoor coil temperature falls below 32
degrees the compressor will be de-energized until the
coil temperature rises above 57 degrees.
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 curve 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 signa 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 rises to approximately 57° F, the
coll 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 caused the heat pump to have a prolonged defrost
cycle, the heat pump control will restore the system to
heating operating automatically after 10 minutes.
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 time to elapse.
There is an initial defrost (init def) jumper on the
control that can be used at any outdoor ambient during
the heating cycle to simulate a 0° coil temperature.
This can be used to check defrost operation of the unit
without waiting for the outdoor ambient to fall into the
defrost region.
