HEATING A COOLING
5F,H
Open-Drive Compressors
INSTALL CRANKCASE HEATER — Wire heater to
relay or set of normally closed auxiliary contacts on
compressor starter to de-energize it when compressor
is operating.
Remove rubber plug from crankcase heater casing
(Fig. 1-8), and insert heater element entirely into casing.
Element should fit snugly, not loosely. Wire to comply
with applicable electrical codes.
When crankcase heater is installed, system can be
operated on single pumpout cycle, unless used with a DX
cooler.
Table 2 lists crankcase heater packages. Table 3 shows
corresponding relays. Use of 2 heaters on a 5H80 or
5H120 compressor requires only one relay.
Control circuit voltage determines relay coil voltage.
This voltage must be specified when ordering relays.
See Accessory Compressor Crankcase Heater Instal­
lation Instructions for additional information.
