11.1 MAIN SAFETY DEVICE
Compressor Protection
High Pressure Switch:
This switch cuts out the operation of the compressor when the discharge pressure exceeds the setting.
Fan motor protection
When the thermistor temperature is reached to the setting, motor output is decreased.
The other way, when the temperature becomes lower, limitation is cancelled.
