the valve rod anticlockwiseuntil hitting lightly.
In case of gas leakage, tighten parts of pipe connection. If
leakage stops, then proceed 6. steps
If it does not stop gas leakage, discharge whole refrigerants from the service
port. After

If the refrigerant of the air conditioner leaks, it is necessary to discharge all the
ƽ
refrigerant. Vacuumize
¿
rst, then charge the liquid refrigerant into air conditio-
ner according to the amount marked on the name plate.
Please do not let other cooling medium, except speci ¿ ed one (R410A), or air
ƽ
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.
