COMPRESSOR HEATERS
Compressor heaters are standard. ZP180 compressors
use 70 W heaters; ZP235, compressor use 120 W heat-
ers and ZP285 and ZP385 use 150 W heaters. If power
is OFF more than two hours, the crankcase heaters must
It is possible that multiple sources of
power can be supplying the unit power
panel. To prevent serious injury or death,
the technician should verify that NO
LETHAL VOLTAGES are present inside
the panel AFTER disconnecting power,
BEFORE working on equipment.
The unit evaporator heater uses 110 VAC.
Disconnecting 120 VAC power from the
unit, at or below freezing temperatures,
can result in damage to the evaporator
and unit as a result of the chilled liquid
freezing.
be energized for 18 hours to 24 hours before restarting
a compressor. This will ensure that liquid slugging and
oil dilution does not damage the compressors on start.
