To prevent the gas leakage, turn the service port's cap, the valve rod's cap for
After attaching the each caps, check the gas leakage around the caps.
CAUTION:
1.If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.
If it does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder

2.Please do not let other cooling medium, except specified one (R410A),
or air enter into the cooling circulation system. Otherwise, there will be
abnormal high pressure in the system to make it crack and lead to
personal injuries.
