Each scroll compressor is equipped with a crankcase
heater.
The proper operation of the crankcase heater is
important to maintain an elevated compressor oil
temperature during the OFF cycle to reduce oil foaming
during compressor starts. When the compressor starts,
the sudden reduction in crankcase pressure causes the
liquid refrigerant to boil rapidly causing the oil to foam.
This condition could damage compressor bearings due
to reduced lubrication and could cause compressor
mechanical failures.
Gas Heat Units
All internal gas piping is factory-installed and pressure
leak-tested before shipment. Once the unit is set into
place, the gas supply line must be field-connected to
the elbow located inside the gas heat control
compartments.
N No otte e:: For conversion from Natural Gas to Propane
refer to the LP Converstion Kit (RT-SVN033*-EN)
for part numbers and installation instructions.
