1. Compressor External Protector (All Models)

If combined temperature/amperage value is above the limit specied by the compressor

manufacturer, the compressor external protector operates independently to turn off the

compressor. The compressor external protector de-energizes the compressor until the

temperature/amperage value returns to an acceptable level.

D. Perimeter and Mullion Heaters (UF/WF only)

UF/WF are equipped with perimeter and mullion heaters. If condensation occurs, check

continuity of heaters.
