At the beginning of the defrost cycle, both the 
outdoor condenser fan and compressor will 
turn off. After approximately 30 seconds, the 
compressor will turn on and begin to heat the 
outdoor coil causing the ice and snow to melt. 
NOTE: While the ice and snow is melting, some 
steam may rise from the outdoor unit as the warm 
coil causes the melting frost to evaporate. When 
defrost is completed, the outdoor fan motor will 
start, and the compressor will turn off again. In 
approximately 30 seconds the compressor will 
start up again and continue normal operation.

System Shutdown
Change the thermostat’s system mode to OFF 
and the fan mode to AUTO (See Figure 1). 
NOTE: The system will not operate, regardless 
of the temperature selector setting.
