B. Dual Control

Fig. 4 Dual Adjustable Pressure Control

Use of the encapsulated pressure control (if applicable)

Fixed suction pressure setting: Cut in = 32 psig; Cut out = 10 psig

Use of the condenser fan control (if applicable for low ambient kit)

Head pressure setting: Cut in=170 psig; Cut out=120 psig; Differential=50 psig

It may need to adjust the setting in the field to prevent short fan cycle.

10.

Use of the crankcase heater (if applicable for low ambient kit)

The crankcase heater is installed around the lower part of the compressor and
shall be turned on all the time. The heater is self-regulated.

CAUTION:
