Operating Instructions
Please read all instructions before servicing this equipment.
Pay attention to all safety warnings and any other special
notes highlighted in the manual. Safety markings are
used frequently throughout this manual to designate a
degree or level of seriousness and should not be ignored.
WARNING indicates a potentially hazardous situation that
if not avoided, could result in personal injury or death.

if not avoided, may result in minor or moderate injury or
property damage.
Please refer to the thermostat manufacturer’s User manual
for detailed programming instructions.
About the Heat Pump
Your heat pump is a unique, all weather comfort-control
appliance that will heat and cool your home year round
and provide energy saving comfort. It’s an unknown fact
that heat is always in the air, even when the outside
temperature is below freezing. The heat pump uses this
basic law of physics to provide energy saving heat during
the winter months. For example, If the outdoor temperature
is 47° F (8° C), your heat pump can deliver approximately
3.5 units of heat energy per each unit of electrical energy
used, as compared to a maximum of only 1 unit of heat
energy produced with conventional heating systems.
In colder temperatures, the heat pump performs like an air
conditioner run in reverse. Available heat energy outside
the home is absorbed by the refrigerant and exhausted
inside the home. This efficient process means you only
pay for “moving” the heat from the outdoors to the indoor
area. You do not pay to generate the heat, as is the case
with more traditional furnace designs.
During summer, the heat pump reverses the flow of the
heat-absorbing refrigerant to become an energy-efficient,
central air conditioner. Excess heat energy inside the
home is absorbed by the refrigerant and exhausted
outside the home.
Cooling Operation
1.Set the thermostat’s system mode to COOL or AUTO
and change the fan mode to AUTO. See Figure 1.
2.Set the temperature selector to the desired temperature
level.The outdoor fan, compressor, and blower motor will
all cycle on and off to maintain the indoor temperature
at the desired cooling level.
NOTE: If the temperature level is re-adjusted, or the
system mode is reset, the fan and compressor in the
outdoor unit may not start immediately. A protective
timer circuit holds the compressor and the outdoor
fan off for approximately three minutes following a
previous operation or the interruption of the main
electrical power.
Heating Operation
1.Set the thermostat’s system mode to HEAT or AUTO
and change the fan mode to AUTO. See Figure 1.
2.Set the temperature selector to the desired temperature
level. The compressor, outdoor fan, and blower motor
will cycle on and off to maintain the indoor temperature
at the desired heating level.
NOTE: If the temperature level is re-adjusted, or the
system mode is reset, the fan and compressor in the
outdoor unit may not start immediately. A protective
timer circuit holds the compressor and the outdoor fan
off for approximately three minutes following a previous
operation or the interruption of the main electrical power.
Emergency Heat
Some thermostats may include a system mode called EM
HT or AUX HT, etc. This is a back-up heating mode that
should only be used if a problem is suspected. With the
mode set to EM HT, etc., the compressor and outdoor fan
will be locked off and supplemental heat (electric resistance
heating) will be used as a source of heat. Sustained use
of electric resistance heat in place of the heat pump will
result in an increase in electric utility costs.
Defrost Operation
During cold weather heating operation, the outdoor unit
will develop a coating of snow and ice on the heat transfer
coil. This is normal and the unit will defrost itself. This unit
features Demand Defrost that monitors ambient and coil
temperatures to regulate the defrost function accordingly.

At the beginning of the defrost cycle, both the outdoor
condenser fan and compressor will turn off. After
approximately 30 seconds, the compressor will turn on
and begin to heat the outdoor coil causing the ice and
snow to melt.
3
USER INFORMATION
NOTE: While the ice and snow is melting, some steam
may rise from the outdoor unit as the warm coil causes the
melting frost to evaporate. When defrost is completed, the
outdoor fan motor will start, and the compressor will turn
off again. In approximately 30 seconds the compressor
will start up again and continue normal operation.
Operating the Heat Pump for Automatic
Cooling and Heating
1.Set the thermostat system mode to AUTO and the
thermostat fan mode to AUTO. See Figure 1.
NOTE: Thermostat styles vary. Some models will not
include the AUTO mode and others will have the AUTO
in place of the HEAT and COOL. Others may include
all three. Refer to the instructions supplied with your
thermostat for specific instructions.
2.Set the thermostat's temperature selector to the desired
heating and cooling temperature level(s). The outdoor
unit and the indoor blower will then cycle on and off
in either the heating or cooling mode of operation
as required to automatically maintain the indoor
temperature within the desired limits.
Operating the Indoor Blower Continuously
The continuous indoor blower operation is typically used to
circulate the indoor air to equalize a temperature unbalance
due to a sun load, cooking, or fireplace operation.
Set the thermostat fan mode to ON (Figure 1). The indoor
blower starts immediately, and will run continually until
the fan mode is reset to AUTO.
The continuous indoor blower operation can be obtained
with the thermostat system mode set in any position,
including OFF.
Shutting the Heat Pump Off
Change the thermostat’s system mode to OFF and the fan
mode to AUTO. See Figure 1. NOTE: The system will not
operate, regardless of the temperature selector setting.

The demand defrost board controls the defrost cycle
in response to ambient temperature, outdoor coil
temperature and accumulated compressor run time. The
heat pump is allowed to operate in the heating mode
until the combination of outdoor ambient and outdoor
coil temperatures indicate that defrosting is necessary,
based on the programmed defrost curve. There are four
preprogrammed defrost curves on the board.
• A jumper pin is used to switch between the different
curves. The default jumper position is curve 1 and is the
recommended setting for most standard applications.
See Table 3 for additional defrost curves settings.
• The factory default setting does not include a 30 second
compressor delay function and has a 40° F defrost
terminate temperature. If additional defrost time is
needed, a higher terminate temperature is available
by selecting a different demand curve. NOTE: The 30
second compressor delay function is optional and based
on the demand curve selected.
10
• The standard defrost cycle will terminate after 13 minutes
and 39 seconds or when the coil temperature reaches
its terminate temperature, whichever occurs first.
• The defrost board is equipped with a 5 minute Anti-Short
Cycle Delay (ASCD). The compressor will not turn on
until it reaches the minimum 5 minute off time.
• The control contains a forced - defrost feature, which
places the system into defrost mode every 6 hours and
4 minutes, unless the coil temperature is above the
selected terminate temperature.
• The system can be manually forced into defrost mode at
any time by shorting the TEST terminals on the demand
defrost board together for more than 9 seconds. The
coil temperature sensor does not need to be cold when
the unit is forced into defrost. After the TEST input is
removed, the defrost mode will terminate in 13.7 minutes,
if the coil temperature is above the terminate set-point,
or when the Y input is removed, whichever occurs first.
NOTE: If a demand curve is selected which has a 30
second compressor time delay in defrost, the delay is
reduced to 10 seconds in TEST mode.
Optional Outdoor Thermostat
An outdoor thermostat can be installed in the field with
2-stage electric heat by removing the orange wire from
the E terminal on the terminal block and connecting to the
outdoor thermostat. Connect the other side of the outdoor
thermostat to W2 from the thermostat.
Optional Electric Heater Kits
Optional electric heater kits are available in 5 kw through
20 kw heating capacities. Single package heat pumps
are designed to allow optional electric heat to be field
installed as required by the building’s particular heating
load. The options available for each unit are shown in the
heater kit installation instructions. A heating/cooling 24V
thermostat should be used when an electric heater kit is
installed. NOTE: A 2-stage heating thermostat is required
if installing a 2-stage heater kit. As previously noted, a
field installed circuit breaker kit is available as a means
of electrical disconnect for the unit. Install the heater kits
as directed by the instructions supplied with the heater
kit. Follow all cautions and warnings as directed.

START UP & adjustments
Pre-Start Check List
√Verify the unit is level and allows condensate to drain.
√Verify the outdoor coil and top of the unit are free from
obstructions and debris, and all equipment access/
control panels are in place.
√ Verify that the duct work is sealed to prevent air leakage.
√Verify that the line voltage power leads are securely
connected and the unit is properly grounded.
√ Verify that the low voltage wires are securely connected
to the correct leads on the low voltage terminal strip.
√Verify that the outdoor fan turns freely.
√Verify that the power supply branch circuit overcurrent
protection is sized properly.
√Verify that the thermostat is wired correctly. The
thermostat system mode should be set to OFF and the
thermostat fan mode should be set to AUTO.
Start-Up Procedure
Close all electrical disconnects to energize the system.
CAUTION:
If the unit is equipped with a crankcase heater,
allow 24 hours prior to continuing the start up
procedures to allow for heating of the refrigerant
compressor crankcase. Failure to comply may
result in damage and could cause premature
failure of the system. This warning should be
followed at initial start up and any time the power
has been removed for 12 hours or longer.
Air Circulation
Leave the thermostat system mode on OFF, and set the
fan mode to ON. Blower should run continuously. Check
the air delivery at the supply registers and adjust register
openings for balanced air distribution. Examine ductwork
for leaks or obstruction if insufficient air is detected. Set
the thermostat fan mode to AUTO. The blower should
stop running.
Short Cycle Protection
1.With the system operating in cooling mode, note the
temperature setting of the thermostat and gradually raise
the set-point temperature until the unit de-energizes.
2.Immediately lower the set point temperature of the
thermostat to its original setting and verify that the
indoor blower is energized.
3.After approximately 5 minutes, verify the compressor
and fan energize and the temperature of the discharge
air is cooler than the room temperature.
System Cooling
1.Set the thermostat’s system mode to COOL and the
fan mode to AUTO. Gradually lower the thermostat
temperature setpoint below room temperature and
verify the outdoor unit and indoor blower energize.
2.Feel the air being circulated by the indoor blower and
verify that it is cooler than ambient temperature. Listen for
any unusual noises. If unusual sounds occur, determine
the source of the noise and correct as necessary.
3.Allow the cooling system to operate for several minutes
and then set the temperature selector above room
temperature. Verify the fan and compressor cycle off
with the thermostat. NOTE: The blower should also
stop unless fan mode is set to ON.
System Heating
If the unit has been equipped with optional electric heater
kits, set the thermostat's system mode to HEAT and the
fan mode to AUTO. Verify the compressor and outdoor
fan are not energized but that the blower and heaters are.
Feel the air being circulated by the indoor blower and verify
that it is warmer than ambient temperature. Listen for any
unusual noises. If unusual sounds occur, determine the
source of the noise and correct as necessary.
Refrigerant Charging
WARNING:
Single Packaged Heat Pumps are shipped fully
charged with R-410A refrigerant and ready
for installation. When a system is installed
according to these instructions, no refrigerant
charging is required. If repairs make it necessary
for evacuation and charging, it should only be
done by qualified, trained personnel thoroughly
familiar with this equipment. Some local codes
require licensed installation/service personnel
to service this type of equipment. Under no
circumstances should the owner attempt to
install and/or service this equipment. Failure to
comply with this warning could result in property
damage, personal injury, or death.
The system refrigerant charge can be checked and
adjusted through the service ports provided at the front
panel. Use only gauge lines which have a Schrader
depression device present to actuate the valve. Draw a
vacuum on gauge lines to remove air before attaching
them to the service ports on the unit.
IMPORTANT NOTES:
• To achieve rated capacity and efficiency the compressor
must be exposed to refrigerant for at least 24 hours prior
to running and then must be run for a minimum of 12
hours.
• The refrigerant charging charts are applicable to
matched assemblies and at listed airflows for the indoor
coil. Assemblies of indoor coils and outdoor units not
listed are not recommended. See Figure 9, Figure 10
(page 16), Figure 11, Figure 12 (page 17), Figure
13, Figure 14 (page 18).
11
Charging an R-410A Unit in AC Mode
(With Outdoor Temperatures Above 65° F)
1.With the system operating at steady-state, measure the
liquid refrigerant pressure in psig at the service valve.
2.Measure the liquid refrigerant temperature in Fahrenheit
at the service valve.
3.For the temperature measured, determine the required
liquid refrigerant pressure from the appropriate charging
charts in Figure 9, Figure 10 (page 16), Figure 11,
Figure 12 (page 17), Figure 13, Figure 14 (page
18).
4.If the pressure measured in step 1 is greater than the
required liquid refrigerant pressure determined in step
4, then there is too much charge in the system. Remove
refrigerant and repeat steps 1 through 3 until the system
is correctly charged.
5.If the pressure measured in step 1 is less than the
required liquid refrigerant pressure determined in step
4, then there is too little charge in the system. Add
refrigerant and repeat steps 1 through 3 until the system
is correctly charged.
Charging an R-410A Unit in Heating Mode
Use the steps below for proper charging of unit in heat
mode:
1.Evacuate the refrigerant system.
2.Weigh in the proper charge as shown on the unit rating
plate (during heating mode operation).
3.Verify the unit is operating properly according to the
System Heating section on page 11.
Verification of charge in Heat Mode
• For units with a restrictor, use Table 5 (page 19),
Table 6 (page 19), Table 7 (page 19), or Table 8
(page 20), as a guide.
• For units with a TXV, the refrigerant system should be
evacuated and the proper charge weighed in as shown
on the unit rating plate.
NOTE: Unit charge MUST be verified in cooling season.
