Operation CHARM: Car repair manuals for everyone.

Preliminary Checking and Charging, Overall System

Sight Glass:




PRELIMINARY CHARGING
1. Open outlet valve of charging cylinder.
2. Slowly open high pressure side valve of manifold gauge to charge refrigerant from the high pressure side.
3. Close high pressure valve after charging approx. 200 g (7.05 oz) refrigerant.

CAUTION:
The refrigerant in charging cylinder is kept in liquid state, so the refrigerant should be charged from high pressure side. Do not start engine with high pressure valve kept open.

Gas Leak Detector:




PRELIMINARY CHECK
1. Make sure that the gauge manifold valve is closed.
2. Check for refrigerant leak from each connector in the system using the leak detector.

At this point, the pressure in the system is not high. Only large amounts of refrigerant leak due to loose pipe Joints, etc. can be detected.

Charging Refrigerant
1. Slowly open high pressure valve of manifold gauge, and charge calculate amount of refrigerant in "CHARGING AND CHECKING". Service and Repair

CAUTION:
The refrigerant in charging cylinder is kept in liquid state, so the refrigerant should be charged from high pressure side. Do not start engine with high pressure valve kept open.

2. Close high pressure valve of manifold gauge.
3. Make sure that the calculated amount of refrigerant remains in sight glass.
4. Close charging cylinder outlet valve.
5. Turn off heater if it is on (when using heater equipped).
