COMPRESSOR HEATERS
Compressor heaters are standard. ZP180 compressors
utilize 70W heaters; ZP235, compressor use 120W
heaters and ZP285, ZP385, and ZP485 utilize 150W
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,
PRIOR to working on equipment.
The unit evaporator heater uses 120VAC.
Disconnecting 120VAC 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 – 24 hours
prior to restarting a compressor. This will assure that
liquid slugging and oil dilution does not damage the
compressors on start.
