No gas leakage?
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 flaring work again and vacuumize, fill up prescribed
refrigerant from the gas cylinder.
6.
from the service port, open 3-way(L) valve and 3-way(G).
Detach the charge hose
Turn the valve rod anticlockwise until hitting lightly.
7.
To prevent the gas leakage, turn the service port's cap, the valve rod's cap for 3-way
(L)valve and 3-way's(G) a little more than the point where the torque increases suddenly.
8.
After attaching the each caps, check the gas leakage around the caps.

CAUTION
●
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 conditio-
ner 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 to make it crack and lead to personal injuries.
