Items
Precautions
4) Refrigerant Charging
Charge refrigerant while operating a compressor as shown above.
5) Pinch the 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
* Test for leaks on the welded or suspicious area with an electronic leakage tester.
7. Pipe arrangement
When replacing components, be sure
in each cycle
each pipe is replaced in its original
position before closing the cover of the
mechanical area.
Compressor
Condenser
Drier
Hot Line
Evaporator
Charging Canister
Bushing
1) Observe the safety precautions for gas handling.
2) Use JIG (or a 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 is not distorted while cutting a capillary tube.
8) Be sure that the suction pipe and the filling tube should not be substituted each other during welding. (High efficiency
pump.)
