General data
2.5 Safety and control Device
Compressor protection
The compressor is protected by the following devices and their combinations.
(1) High pressure switch: This switch cuts out the operation of the compressor when the discharge pressure exceeds the
setting.
(2) Low pressure switch: This switch cuts out the operation of the compressor when the suction 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 canceled.
