5.2 Safety protection and control
Compressor protection
The compressor is protected by the following devices:
• High pressure switch: this stops the compressor when the discharge pressure exceeds the set value.
• Oil heater: this prevents oil from being lost during cold starts, as it is enabled while the compressor is at a standstill.
• Fan motor protection: internal thermostat located in the fan motor winding. This stops the fan motor when the winding
temperature exceeds the set value.
