5. How To Charge R-600a Refrigerant

NO.

SVC process

Details

1. Connect the discharging hose to

the pinch-plier

2. The outlet of discharging hose should

be placed to the outdoor(window)

1. Fix the pinch-plier to the compressor

charging pipe.

2. Pinch-plier should not be moving freely.

※

If that is moving freely, it would cause

fire/explosion as leakage gas in the room.

1. Discharge the R-600a ref. to outdoor.

[Befor connecting the vacuum pump]

※

It should have enough time more than

7 minutes to discharge.

1. And then, connect the vacuum pump

to the outlet of discharging hose

1. Disassembe the each pipe (Del-pipe,

Suc-pipe, Capi-pipe, Dryer & Hot-pipe)

※

Vacum pump should be placed at

the outdoor where is able to clear air easily.

※

It should have enough time

more than 10 minutes to discharge.

※

Caution ; A part is easily damaged

by flame so that disassemly should
be done carefully.

1. Change the comp. & dryer.

※

You should check the comp. spec.

and assemble correctly.

1. Weld the each pipe.

※

Copper-Copper welding - 5% rod

△

Copper-Steel welding - 35% rod

1. Decap the couplig pipe cap and

disassemble the vlave ass'y.

※

If you don't disassemble, the coupling

rubber would be melted.

1. Weld after inserting the coupling pipe

to the compressor.

※

Use the wet cloth for preventing the

other part of machinery-room from damage.
