Installation Instructions

Be sure to use the same insulating materials when you buy the brass pipe. (More than

9mm thick)

Use the market brass pipe.

Use frozen oil

Bend the pipe with thumb

Min-radius 100mm

Make the ends

straight

2. Locate The Pipe

1) Drill a hole in the wall (suitable just for the size of the wall conduit, 90mm in general), then

set on the fittings such as the wall conduit and its cover.

2) Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air

in, which will cause water leakage by condensation.

3) Pass the bound connecting pipe through the wall conduit from outside. Be careful of the

pipe allocation to do no damage to the tubing.

3. Connect the pipes.

4. Then, open the stem of stop valves of the outdoor unit to make the refrigerant pipe conne-

cting the indoor unit with the outdoor unit fluently flow.

5. Be sure of no leakage by checking it with leak detector or soap water.

6. Cover the joint of the connecting pipe to the indoor unit with the soundproof/insulating

sheath (fittings), and bind it well with the tapes to prevent leakage.

Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4

rounds with hands before fasten the flare nuts. (Refer to chart 14)

Be sure to use two wrenches simultaneously when you connect or disconnect the pipes.

Cautions

2) The stop valve of the outdoor unit should be closed absolutely (as original state). Every

time you connect it, first loosen the nuts at the part of stop valve, then connect the flare

pipe immediately (in 5 minutes). If the nuts have been loosened for a long time, dusts

and other impurities may enter the pipe system and may cause malfunction later. So

please expel the air out of the pipe with refrigerant before connection.

The bending angle should not exceed 90 C

Bending position is preferably in the bendable pipe. The larger the better it is .

Do not bend the pipe more than three times.

3) Expel the air (refer to the Expel The Air ) after connecting the refrigerant pipe with the

indoor unit and the outdoor unit.

Then fasten the nuts at the repair-points.

Notices For Benable pipe.

Cut out a desired concave at the bending part of the insulating pipe.

Then expose the pipe(cover it with tapes after bending).

To prevent collapsing of deforming, please bend the pipe at its biggest radius.

Use bender to get a small radius pipes.

Bend the connecting pipe of small wall thickness.
