6. GAS CHARGING (AFTER EVACUATION)
Connect the charge hose to the charging cylinder.
Connect the charge hose which you disconnected 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 level the cylinder so that the system can
be charged with liquid.
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.
Open the valve (Low side on the charge set) and charge the system with liquid refrigerant.
If the system can not 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).
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.
Immediately disconnect the charge hose from the 3-way valve’s service port.
Stopping partway will allow the gas to be discharged.
If the system has been charged with liquid refrigerant while operating the air conditioner
before disconnecting the hose.
Mount the valve caps and service port cap.
Use torque wrench to tighten the service port cap to a torque of 1.8kg.m.
Be sure to check for gas leakage.
