2. Place SYSTEM switch in COOL position and FAN
switch in AUTO position. Set thermostat cooling control
below room temperature to start cooling cycle. Observe
that compressor, outdoor fan, and indoor blower motors
start. Observe that unit shuts down when control set
ting is satisfied. Wait 5 minutes for pressures to
equalize.
3. Place SYSTEM switch in HEAT position, and leave
FAN switch in AUTO position. Increase thermostat
heating control setting gradually until thermostat
“calls” for heat. Observe that compressor, outdoor fan,
and indoor blower motor start. If supplemental electric
heater is being used in the system, increase thermostat
heating control setting an additional 6 degrees. Observe
that the supplemental electric heater energizes. Set
control setting below room temperature, and observe
that heater deenergizes and that heat pump shuts down.
4. If supplemental electric heater is being used in the
system, leave FAN switch in AUTO position, SYSTEM
switch in HEAT position, and move emergency heat
switch from NORM, position to EM. HT. position. Set
thermostat control setting above room temperature to
start heating cycle. Observe that all supplemental
electric heat is energized, that indoor blower motor
starts, that emergency heat indicator bulb lights, and
that compressor and outdoor fan do not start. When con
trol setting is satisfied, observe that heater deenergizes
and that blower motor stops; however, indicator light
should remain on as long as emergency heat switch is in
EM. HT. position.
5.
If autochangeover thermostat P/N 34427DP115 is
being used, place both SYSTEM and FAN switches in
AUTO position. Observe that heat pump operates in
heating mode when heating control selector is set above
room temperature, and operates in cooling mode when
cooling control selector is set below room temperature.
B. Checking and Adjusting Refrigerant Charge
The refrigerant system is fully charged with R-22
refrigerant, tested, and factory-sealed. For most applica
tions, the factory charge is the correct amount for the best
performance; however, this charge rnay require a slight
adjustment to attain rated performance.
