Procedure:
1. Connect the charge hose to the gas charging cylinder.
Connect the charge hose which you disconnected from the vacuum pump to the valve at
the bottom of the cylinder.
2. Purge the air from the charge hose.
Open the valve at the bottom of the cylinder and press the check valve on the charge set
to purge the air. (Be careful of the liquid refrigerant). The procedure is the same if using
a gas cylinder.
3. Open the valve (Low side) on the charge set and charge the system with liquid refrigerant.
If the system cannot be charged with the specified amount of refrigerant, it can be
charged with a little at a time (approximately 150g each time) while operating the air
conditioner in the cooling cycle; however, one time is not sufficient,wait approximately
1 minute and then repeat the procedure. (pumping down-pin)
