installation manual

●

Fix the main body and the outside frame with the fix board of

waist- shape hole (in two places).

Hang one side of the fix board of the waist-shaped hole on the

①

hook of the main body.

②

Tighten the other side of the board with screw to the outside
frame.

③

Cut off the surplus part of the board with pliers.

Bend the top of the broken end.

④

When hanging up the outside frame with the fix board of waist-
shaped hole and the belt, stick the outside frame tightly to the
ceiling and fix it.

Fig.7-16

●

Install the inner frame on the outside frame (the inverse sequence
of unloading the inner frame).

Fig.7-17

Connect the remote-control receiver with the indoor unit signal
wires and fix it.

●

Install remote controller.

●

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.

①

Bend the tubing in proper way. Don’t harm them.

②

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

)

③

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.

●

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.

Use the market brass pipe.

Be sure to use the same insulating materials when you buy the
brass pipe. (More than 9mm thick)

INSTALL THE CONNECTING PIPE

Use frozen oil

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 outdoor 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.

Bend the pipe with thumb

Make the ends
