4. Detach Liquid and Gas Pipe
- Gas Pipe: Remove the Cap by Brazing
- Liquid Pipe: There are 2 kinds of Liquid Pipe.
3. Cut the refrigerant pipe (Liquid Pipe edge)
and make sure the factory charged refriger-
ant is emerging out. (This confirms there is
no leakage.)
- If you do not use proper cutter size
when cutting liquid pipe, it would make
damage to the gas pipe.
Completely remove the refrigerant and then do brazing. Otherwise, high pressure is a risk
of injury due to explosions
