id0740b3103700
Construction
• A dual pressure type has been adopted.
Operation
• The high pressure switch turns off to protect refrigerant cycle when the pressure on the high pressure side is excessively high and the PCM turns off the magnetic clutch.
• The medium-pressure switch turns on when the refrigerant pressure is approx. 1.57—1.77 MPa {16.0—18.0 kgf·cm2, 227—257 psi} and the PCM operates the main fan.
