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 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.
