Low Pressure Sensor / Switch: Description and Operation
Low Pressure Cut-Off Switch
DESCRIPTION
The Low Pressure Cut-Off Switch, located on the H-valve, is wired in series with the compressor magnetic clutch. It cuts off the electrical power
supply to the clutch when refrigerant pressure drops below the control point of the switch.
OPERATION
Whenever the system is inactivated by the low pressure cut-off switch due to refrigerant loss, the refrigerant oil may have been lost. Therefore, to
prevent damage to the compressor due to operation without sufficient lubrication, the leak must be repaired and the compressor oil level checked
before final charge of the system.
The switch is a sealed, factory calibrated unit. No attempt shall be made to adjust or otherwise repair it. If it is found to be defective it must be
replaced.
