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.
