open 2-way valve and 3-way. Turn
the valve rod anticlockwise until hitting lightly.
In case of gas leakage, tighten parts of pipe connection. If

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.

Pipe cutting is carried out with a pipe cutter and burs must
be removed.
After inserting the

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-
neraccordingtotheamountmarkedonthenameplate.
Please do not let other cooling medium, except speci
ed one (R410A), or air
enter into the cooling circulation system. Otherwise, there will be abnormal
