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 dis-
connecting power, PRIOR to working
on equipment.
The unit evaporator heater uses
120VAC. Disconnecting 120VAC pow-
er 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.
