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).
3) Put the charging cylinder onto the electronic scale and record the weight.
4). Open the valves (Low side) on the charge set and charge the system with liquid refrigerant
If the system cannot be charge with the specified amount of refrigerant, or can be charged with a little at
a time (approximately 150g each time) , operating the air conditioner in the cooling cycle; however, one
time is not sufficient, wait approximately 1 minute and then repeat the procedure.
