• Procedure

(1)Connect the charge hose to the charging cylinder.

–Connect the charge hose which you dis-con- nected from the vacuum pump to the valve at the bottom of the cylinder.

–If you are using a gas cylinder, also use a scale and revers the cylinder so that the system can be charged with liquid.

(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 refriger- ant). The procedure is the same if using a gas cylinder.

(3)Open the valve (Lo side on the charge set and charge the system with liquid refrigerant.

–If the system can not be charged with the spec- ified 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 suffi- cient, wait approximately 1 minute and then repeat the procedure (pumping down-pin).

\

This is different from previous procedures. Because you are charging with liquid refrigerant from the gas side, absolutely do not attempt to charge with larger amounts of liquid refrigerant while operating the air conditioner.

(4)Immediately disconnect the charge hose from the 3-way valve’s service port.

–Stopping partway will allow the gas to be dis- charged.

–If the system has been charged with liquid refrigerant while operating the air conditioner turn off the air conditioner before disconnecting the hose.

(5)Mount the valve stem nuts and the service port nut.

–Use torque wrench to tighten the service port nut to a torque of 1.8 kg.m.

–Be sure to check for gas leakage.
