Dual Switch: Notes
The dual switch is located on the high pressure line above the receiver drier. When an abnormal pressure occurs in the high pressure line, the dual switch is forced to OFF to stop operation of the compressor.
- When the pressure is abnormally low [177 kPa (1.8 kg/cm2
, 26 psi) or less]
The dual switch is forced to OFF to prevent operation of the compressor when there is no gas caused by leakage of the refrigerant.
- When the pressure is abnormally high [2,940 kPa (30 kg/cm2
, 427 psi) or more]
The dual switch is forced to OFF to protect the air-conditioning cycle parts.
