• Keeping the valve of the outdoor unit, be sure to charge the liquid refrigerant into the service port at the liquid
side.
• If the specifi ed of refrigerant cannot be charged, fully open the valves of the outdoor unit at liquid and gas sides,
7/8 in.
operate the air conditioner in COOL mode, and then charge refrigerant into service port at the L gas side.
22.2 mm
In this time, choke the refrigerant slightly by operating the valve of the canister to charge liquid refrigerant.
• The liquid refrigerant may be charged suddenly, therefore be sure to charge refrigerant gradualy.
