5.1 The Procedure of Connecting Pipes
5.1.1 Measure the necessary length of the connecting pipe, and
make it as follows.
1) Connect the indoor unit at first and then the outdoor unit.
a. Bend the tubing in proper way. Do not damage them.
1. Coat the surfaces of the flare pipe and the joint nuts with
frozen oil. Turn by hand 3-4 times and then fasten them with a
wrench.
2. Use two wrenches simultaneously when you connect or
disconnect the pipes.
CAUTION
2) The stop valve of the outdoor unit should be fully closed (as
per the original state). Every time you connect the pipes, first
loosen the nuts at the stop valve. Then connect the flare pipe
(within in 5 minutes). If the nuts have been loosened for a long
time, dust and other impurities may enter the pipe system and
cause a fault. Expel the air out of the pipe with refrigerant
before connecting it.
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.
Note for Bendable Pipes.
The bending angle should not exceed 90°.
The bending position is preferably for the bendable pipe. The
larger it is, the better it is.
Do not bend the pipe more than three times.
Bend the connecting pipe of a small wall thickness.
Cut out a desired concave at the bending part of the insulating
pipe.
Then expose the pipe (cover it with tape after bending).
To prevent collapsing or deformation. Bend the pipe at its
widest radius.
Use a bender on low radius pipes.
Use a normal brass pipe.
Use the same insulating materials for the brass pipe. (More than
9 mm thick)
Fig. 5-1
Fig. 5-2

Bend the pipe with your 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, 90 mm 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 tape. Do not let air in to avoid leaks due to condensation.
3) Pass the bound connecting pipe through the wall conduit from
outside. Consider the pipe allocation to do no damage to the
tubing.
3. Connect the pipes.
4. Then, open the stem of the stop valves of the outdoor unit to
ensure regular flow in the refrigerant pipe that connects the indoor
and outdoor units.
5. Ensure there are no leaks by checking with a leak detector or
soapy water.
6. Cover the joint of the connecting pipe to the indoor unit with the
soundproof/insulating sheath (fittings), and bind it well with tape to
prevent leaks.
