Check whether the height drop between the indoor unit and
outdoor unit, the length of refrigerant pipe, and the number of
the bends meet the following requirements:
The max height drop and The length of refrigerant pipe deponding
on the ouotdoor unit.(If the height drop is more than 10m, you
had better put the outdoor unit over above the indoor unit.)
The number bends fewer than 15.
Do not let air, dust, or other impurities fall in the pipe system
during the time of installation.
The connecting pipe should not be installed until the indoor and
outdoor units have been fixed already.
Keep the connecting pipe dry, and do not let moisture in
during installation.
The Procedure of Connecting Pipes
Measure the necessary length of the connecting pipe, and make
it by the following way.
Connect the indoor unit at first, then the outdoor unit.
Bend the tubing in proper way. Don,t harm them.
Daub the surfaces of the flare pipe and the joint nuts with frozen
oil, and wrench it for 3~4rounds with hands before fasten the
flare nuts. (Refer to Fig.8-1)
Be sure to use two wrenches simultaneously when you connect
or disconnect the pipes.
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.
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.
The bending angle should not exceed 90℃
Bending position is preferably in the bendable pipe. The larger
the better it is .
Do not bend the pipe more than three times.
Bend the connecting pipe of small wall thickness.
Cut out a desired concave at the bending part of the insulating
pipe.
8. INSTALL THE CONNECTING PIPE
Connect the remote control receiver with the indoor unit signal
wires and fix it.

Locate The Pipe
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.
Bind the connecting pipe and the cables together tightly with
binding tapes. Do not let air in, which will cause water leakage
by condensation.
Pass the bound connecting pipe through the wall conduit from
outside. Be careful of the pipe all ocation to do no damage to the
tubing.
Connect the pipes.
Then, open the stem of stop valves of the outdoor unit to make
the refrigerant pipe connecting the indoor unit with the outdoor
unit fluently flow.
Be sure of no leakage by checking it with leak detector or soap
water.
Cover the joint of the connecting pipe to the indoor unit with the
sound proof/insulating sheath (fittings), and bind it well with the
tapes to prevent leakage.
