No gas leakage?
In case of gas leakage, tighten parts of pipe connection. If leakage stops,
then proceed step 6. If leak continues, remove the refrigerant used for the
leakage check and flare tubes again. Repeat vacuum and leak and if no
leakage, proceed to step 6.
6.
Detach the charge hose from the service port, open 2-way valve and 3-way. Turn
the valve stem counterclockwise.
7 .
To prevent the gas leakage, replace the service port and valve stem caps securely.
8.
After attaching each cap, check for gas leakage around the caps.

CAUTION
●
If the refrigerant of the air conditioner leaks, it is necessary to discharge all the
refrigerant. Vacuum first, then charge the liquid refrigerant into air conditioner
according to the amount marked on the name plate.
●
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 casuing damage and possibly personal injuries.
