Refrigerant Circuit Pressure Sensor -G805-, Removing And Installing: Notes

Danger due to refrigerant coming out under pressure when there is damage to the refrigerant line.

Danger of frost bite to skin and other parts of the body.

• Carefully loosen the pressure sensor -1- while noting the connection between the switch connection -3- and the refrigerant line -4-.
• If the connection between the switch connection -3- and the refrigerant line -4- becomes deformed while loosening the pressure sensor -1- (for example, because of a stuck O-ring seal), counterhold on the switch connection -3- with suitable pliers when loosening the pressure sensor -1-.

Danger due to refrigerant coming out under pressure when there is a defective valve in the refrigerant circuit.

Danger of frost bite to skin and other parts of the body.

• If refrigerant leaks out of the switch connection for longer than one second when loosening the pressure sensor -1- immediately retighten the pressure sensor -1-.
• Discharge the refrigerant circuit to remove. Refer to Refrigerant Circuit (Refrigerant R134a Servicing, Refrigerant Circuit, Working with A/C Service Station) or Working with A/C Service Station (1 Of 2) / Working with A/C Service Station (2 Of 2) .
• Replace the fault valve in the refrigerant line switch connection. Refer to A/C SYSTEM, GENERAL INFORMATION or GENERAL DESCRIPTION - REFRIGERANT CIRCUIT COMPONENTS .

Danger due to refrigerant coming out under pressure.

Danger of frost bite to skin and other parts of the body.

• Extract the refrigerant and immediately open the refrigerant circuit after that.
• If the refrigerant was extracted more than 10 minutes in the past and the refrigerant circuit was not opened, extract the refrigerant again. Pressure in the refrigerant circuit is caused by evaporation.
