START-UP

CRANKCASE HEATER

The crankcase heater must be energized at least 8 hours
before starting the compressor. To energize the crankcase
heater, the main disconnect switch must be closed. During
this 8 hour period, the system switch on the room thermostat
must be OFF to prevent the compressor from starting.
Do not attempt to start the compressor without at
least 8 hours of crankcase heat or compressor
damage can occur.
