Precautions
4) Refrigerant Charging
Charge refrigerant while operating a compressor as shown above.
5) Pinch a charging pipe with a pinch-off plier after completion of charging.
6) Braze the end of a pinched charging pipe with copper brazer and take a gas leakage test
on the welded parts.
6. Gas-leakage test
* Take for leaks on the welded or suspicious area with an electronic leakage tester.
7. Pipe arrangement
Check each pipe is placed in its original
in each cycle
place before closing a cover back-M/C
after completion of work. Particularly
control the size of Joint Drain Pipe
Compressor
Condenser
Drier
Evaporator
Charging Canister
Bushing
1) Observe the safety precautions for gas handling.
2) Use JIG (or wet towel) in order to prevent electric wires from burning during welding. (In order to prevent insulation
break and accident.)
3) The inner case will melt and the insulation will burn.
4) The copper piping will oxidize.
5) Do not allow aluminum and copper pipes to touch. (In order to prevent corrosion.)
6) Observe that the inserted length of a capillary tube into a drier should be 12 mm.
7) Make sure that the inner diameter should not be distorted while cutting a capillary tube.
8) Be sure that a suction pipe and a filling tube should not be substituted each other during welding. ( High efficiency
pump.)
