Figure 6. Heater Kit Accessory Installation
Crankcase Heater (if used)
Some models may be equipped with a crankcase heater
to prevent excessive migration of liquid refrigerant into the
compressor during off cycles. Power must be maintained
to the unit to keep this feature active.
Except as required for safety while servicing, do not open
the system disconnect switch.
Heater Kit Accessory (if used)
The unit is fully equipped for cooling operation without
auxiliary heat. A heater kit accessory may also be used. To
install the heater kit accessory (see Figure 6):
1.
Disconnect the power and open the main control
access.
2.
Disconnect the plug separating the high voltage wire
harness. Remove the high voltage wire harness plug
and discard.
3.
Remove the heater blockoff by removing the four
screws holding it in place.
4.
Insert the heater into the control panel and fasten in
the same mounting holes.
5.
Plug the heater wiring harness into the wire harness
on the control assembly. Field wiring of the auxiliary
heater is separate from the unit power supply. Wire the
power supply wiring for the heater to the appropriate
connections on the heater kit.
