shorted, and/or improperly wired circuits.
Functional Checkout:
CAUTION:
If equipped with a compressor
crankcase heater, wait 24 hours prior
to performing a function checkout to
allow for heating of the compressor
crankcase. Failure to comply may
result in damage and could cause
premature failure of the system.
Indoor Blower — Set the thermostat function
switch to COOLING and the fan switch to ON.
Verify that the indoor blower is operating and
that airflow is not restricted. Set the fan switch
back to AUTO.
Low-Pressure Switch — A low-pressure
switch is factory-installed in select models only.
If provided, this switch is located in the suction
line internal to the outdoor unit. The switch is
designed to protect the compressor from a loss
of charge. Under normal conditions, the switch
is closed. If the suction pressure falls below 5
psig, then the switch will open and de-energize
the outdoor unit. The switch will close again
once the suction pressure increases above 20
psig. Please note that the switch interrupts the
thermostat inputs to the unit. Thus, when the
switch opens and then closes, there will be a 5
minute short cycling delay before the outdoor
unit will energize.
Cooling — Gradually lower the thermostat
temperature setpoint below the actual room
temperature and observe that the outdoor unit
and indoor blower energize. Feel the air being
circulated by the indoor blower and verify that
it is cooler than ambient temperature. Listen
for any unusual noises. If present, locate and
determine the source of the noise and correct
as necessary.
Short Cycle Protection — With the system
operating in COOLING mode, note the setpoint
temperature setting of the thermostat, and
gradually raise the setpoint temperature until
the outdoor unit and indoor blower de-energize.
Immediately lower the setpoint temperature of
the thermostat to its original setting and verify
that the indoor blower is energized and that the
outdoor unit remains de-energized. Verify that,
after approximately 5 minutes, the outdoor unit
energizes and that the temperature of the air
supplied to the facility is cooler than ambient
temperature.
Heating — Lower the thermostat setpoint tem-
perature to the lowest obtainable setting and set
the thermostat function switch to HEATING.The
indoor blower and outdoor unit should stop run-
ning. After a minimum of five minutes, increase
the setpoint temperature of the thermostat to the
maximum setting.Verify that the outdoor unit and
indoor blower have energized. Feel the air being
circulated by the indoor blower and verify that
it is warmer than ambient temperature. Listen
for any unusual noises. If present, locate and
determine the source of the noise and correct
as necessary.
OUTDOOR THERMOSTAT (if supplied)
The outdoor thermostat prevents the electrical
auxiliary heat (if used) from operating when the
outdoor temperature is above 40°F.
Defrost Cycle Timer — The defrost cycle timer
controls the time interval of the hot gas defrost
after the defrost sensor closes. It is located
in the lower left corner of the defrost control
board. Three interval settings are available: 30
minutes, 60 minutes, and 90 minutes.Time setting
selection is dependent on the climate where the
unit is being installed.
Example 1. Dry climate of Southern
Arizona. A 90 minute setting is
recommended.
Example 2. Moist climate of Seattle,
Washington. A 30 minute setting is
recommended.

11
To set the cycle timer, place the timing pin on
the defrost control board to the desired time
interval post.
Note: All units are shipped from the factory with
the default time setting of 30 minutes. Maximum
heating performance can be achieved by setting
the time to 90 minutes.
Defrost Test Procedure
1. Terminals “R”-”C”must have 18-30v present
between them in order for time delay and
defrost sequences to be initiated.
2. With compressor running in heat mode,
first jump the “T2”-”DFT” test pins. This
will indicate to board that defrost T-stat is
closed. Defrost T-stat closes at 32°, opens
at 68°.
3. Next jump the “Test” pin to “C” on terminal
strip.This will initiate defrost test in 5, 10 or
15 seconds (This is determined by 30, 60
or 90 minutes defrost pin settings). Factory
setting will be 30 minutes.
4. When the reversing valve shifts to the
defrost mode, quickly remove jumper from
“Test”-”C”. If the jumper is not removed
within a 5 second period, the defrost test
will terminate. Unit will continue to stay in
defrost mode Until :
A) Board recognizes that defrost
sensor has reached 68° and
opened or
B) “T2”-”DFT” jumper is removed or
C) 10 minutes have elapsed (board
override)
If the above steps will not initiate a defrost, replace
the defrost board.
Anti Short Cycle Timer Test
The 5 minute time delay feature can be bypassed
or shortened to 1 second by jumping the “Test”
to “C” terminal.
Note: If jumper is left on the “Test” to “common”
pins permanently, the defrost cycle will become
inoperable.
Optional Equipment — A functional checkout
should be performed in accordance with
the checkout procedures supplied with the
equipment.
Adjustment of Refrigerant Charge:
CAUTION:
