Install the panel on the main body with bolt (M5×16) and
washer.
(Refer to Fig.5-11 )
Adjust the four panel hook screws to keep the panel
horizontal, and screw them up to the ceiling evenly.
Regulate the panel in the direction of the arrow in
Fig.5-11.
slightly to fit the panel's center to the center of the ceiling's
opening. Guarantee that hooks of four corners are fixed well.
Keep fastening the screws under the panel hooks, until the
thickness of the sponge between the body and the panel's
outlet has been reduced to about 4~6mm. The edge of the
panel should contact with the ceiling well.

Malfunction described in
Fig.5-13
can be caused by
inappropriate tightness the screw.
If the gap between the panel and ceiling still exists after
fastening the screws, the height of the indoor unit should
be modified again.
( Refer to Fig.5-14-left)
You can modify the height of the indoor unit through the
openings on the panel's four cor ners, if the lift of the
indoor unit and the drainpipe is not influenced
(Refer to
Fig.5-14-right).
Hang the air-in grill to the panel, then connect the lead
terminator of the swing motor and that of the control box
with corresponding terminators on the body respectively.
Relocate the air-in grid in the procedure of reversed order,
install the air-in grid.

Please operate according
to the direction of the arrow,
or it can not be disassembled
when it is necessary.
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
refrigerant oil, and wrench it for 3~4rounds with hands before
fasten the flare nuts. (Refer to
Fig.6-1
)
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 bendable pipe.
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.
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).

6. INSTALL THE CONNECTING PIPE
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
should 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 do the
