SECTION 6 - TECHNICAL DATA
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
120 VAC. Disconnecting 120 VAC
power from the unit, at or below freez-
ing temperatures, can result in damage
to the evaporator and unit as a result
of the chilled liquid freezing.
