ELECTRICAL DATA
Installation
TABLE 1 – MICRO PANEL POWER SUPPLY
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.
