Final Inspection & Start-up
(continued)
starts running. The compressor and outdoor fan should then turn on
and cold air will begin to flow from the unit. Let the unit continue
operating to cool the room and remove humidity.
After the unit starts running and the space gets cooler, adjust the
3.
thermostat to a warmer temperature until the compressor cycles
off.
If a colder room temperature is desired, adjust the thermostat to a
4.
cooler temperature setting, turning the compressor and both fans
back on.
If a warmer room temperature setting is desired, adjust the thermo-
5.
stat to a warmer temperature. The cooling mode will cease and the
compressor and outdoor fan will stop. The indoor fan will switch
off after the sixty-second purge time has elapsed.
Place the thermostat or system switch in the
6.
OFF
position.
All operation should stop.
NOTICE
The room temperature must be above 65°F (29°C) for the
compressor to operate in cooling mode on PTHP's with unit-
mounted controllers.
Place system switch in the
7.
OFF
position. All operation should stop.
Heating operation — heat pump units — outdoor
temperature above 40°F (4°C)
Place
1.
the thermostat or system switch in the
HEAT
position.
Adjust the thermostat to a warmer temperature setting
2.
until the
indoor fan start running. The compressor and outdoor fan should
then turn on and warm air will begin to flow from the unit.
After the unit starts running and the space gets warmer, adjust the
3.
thermostat to a cooler temperature until the compressor cycles off.
For a warmer room temperature,
4.
adjust the thermostat to a warmer
temperature setting turning the indoor and outdoor fans, and
compressor back on.
If a cooler room temperature is desired,
5.
adjust the thermostat to
a cooler temperature setting. The heating mode will cease and the
compressor and outdoor fan will stop. The indoor fan will switch
off after the sixty-second purge time has elapsed.
NOTICE
Room temperature must be below 85°F (29°C) for the compres-
sor to operate in heating mode on PTHP's with unit-mounted
controllers. .
Place the thermostat or system switch in the
6.
OFF
position.
All operation should stop.
NOTICE
Heat pump units are “Limited Range” equipped with back-
up electric resistance heat. Limited Range heat pumps are
designed to operate when outdoor temperatures are between
75°F(24°C)and 40°F (4°C) and with a maximum indoor tem-
perature of 85°F (29°C) . When the outdoor temperature falls
below approximately 40°F (4°C) the unit will switch from heat
pump to electric resistance heat, or hydronic heat if optionally
added. Electric heat or hydronic heat will then remain as the
heat source until the outdoor temperatures rise above 50°F
(10°C). The electric heat and heat pump will NOT operate
simultaneously.
Auxiliary heating operation — heat pump units —
outdoor temperature below 40°F (4C°) — electric
option
Place
1.
the thermostat or system switch in the
HEAT
position.
Adjust the thermostat to a warmer temperature until the indoor
2.
fans start running and the electric coil starts emitting heat.
After the unit starts running and the space gets warmer, adjust
3.
the thermostat to a cooler temperature until the electric heater
turns off.
If a warmer room temperature is desired, adjust the thermostat to
4.
a warmer temperature setting, which will turn the electric heater
back on.
If a cooler room temperature is desired,
5.
adjust the thermostat
to a cooler temperature setting until the electric heater turns off.
The indoor fan will switch off after the sixty-second purge time
has elapsed.
Place the thermostat or system switch in the
6.
OFF
position.
All operation should stop.
