8 | INSTALL THE CONNECTING PIPE
■
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.
■
Fit the panel in the direction of the arrow in Fig.5-11 slightly to
fit the panel's centre to the centre of the ceiling's opening. Ensure
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. (Refer to Fig.5-12)
• Malfunction described in Fig.5-13 can be caused by inappro-
priate tightness of the screw.
• If the gap between the panel and ceiling still exists after fasten-
ing 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 open-
ings on the panel's four corners, if the lift of the indoor unit and
the drainpipe is not influenced (Refer to Fig.5-14-right).
3.
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.
4.
Relocate the air-in grid in the procedure of reversed order,
install the air-in grid.

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 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, using the
following process.
• Connect the indoor unit at first, then the outdoor unit.
Bend the pipe using a pipe bender careful not to damage
the pipe.
Cover the surfaces of the flare pipe and the joint nuts with oil,
and tighten it with 3~4 turns 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.
■
Notices for flexible pipe.
3
• The bending angle should not exceed 90°C.
• 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 a pipe bender.
■
Use insulation material to cover the pipes. (More than 9 mm thick).
