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 aring work again and vacuumize, ll up prescribed
refrigerant from the gas cylinder.

The power source must be exclusively used for air conditioner. (Over I0A)
In the case of installing an air conditioner in a moist place, please install an ea-
For installation in other places, use a circuit breaker as far as possible.
Pipe cutting is carried out with a pipe cutter and burs must be removed.
After inserting the are nut, aring work is carried out.
If the refrigerant of the air conditioner leaks, it is necessary to discharge all the
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 (R32), 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.
