FACTORY INSTALLED ACCESSORIES

HARD START COMPONENTS

tart components are factory installed.

HIGH AND LOW PRESSURE CONTROLS

(HPC OR LPC)

Pressure controls are factory installed.

These controls keep the compressor from operating in pressure ranges which can cause

damage to the compressor. Both controls are in the low voltage control circuit.

High pressure control (HPC) is an automatic reset which opens near 610 PSIG and clos-

es near 420 PSIG.

The low pressure control (LPC) is an automatic reset which opens near 50 PSIG and

closes near 95 PSIG.

COMPRESSOR SOUND WRAP

All (-)ARL and (-)ASL units are factory equipped with compressor sound wraps to

reduce operating noise levels.

COMPRESSOR CRANKCASE HEATER (CCH)

The 5-ton (-)ARL is factory equipped with a crankcase heater. Refrigerant migration

during the off cycle can result in a noisy start up. The crankcase heater minimizes

refrigeration migration and helps reduce start up noise or bearing “wash out.”

The heater is located on the lower half of the compressor shell. Its purpose is to

drive refrigerant from the compressor shell during low outdoor ambient conditions

(below 75°F), thus preventing damage to the compressor during start-up. At initial

start-up or after extended shutdown periods during low outdoor ambient conditions

(below 75°F), make sure the heater is energized for at least 12 hours before the

compressor is started. (Disconnect switch on and wall thermostat off.)

CONTROL BOX COVER

The control box cover allows access to the Comfort Control System™ diagnostic

chart is provided on the control box cover.
