12 MAIN SAFETY DEVICES
Compressor Protection
The compressor is protected by the following devices and their combinations.
• High Pressure Switch: This switch cuts out the operation of the compressor when the discharge pressure exceeds the setting.
Oil Heater: This band type heater protects against oil foaming during cold starting, as it is energized while the compressor is
stopped.
AC Fan Motor Protection
Internal thermostat: Embedded in the fan motor winding, this internal thermostat cuts out the operation of the fan motor when the fan
motor winding temperature exceeds the setting.
