COMPRESSOR HEATERS
Compressor heaters are standard. ZP180 compres-
sors utilize 70 W heaters; ZP235, compressor use 120
W heaters and ZP285, ZP385, and ZP485 utilize 150
W heaters. If power is OFF more than two hours, the
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 120 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.
Voltage Limitations
The following voltage limitations are absolute and
operation beyond these limitations may cause serious
damage to the compressor.
crankcase heaters must be energized for 18 hours to 24
hours before restarting a compressor. This will assure
that liquid slugging and oil dilution does not damage
the compressors on start.
