The existing ceiling (to be horizontal)
1
Cut a quadrangular hole of 880x880mm in the ceiling
according to the shape of the installation paper board.
(Refer to Fig.1-2)
The center of the hole should be at the same position of
that of the air conditioner body.
Determine the lengths and outlets of the connecting pipe,
drainpipe and cables.
To balance the ceiling and to avoid vibration, please
enforce the ceiling when necessary.

Select the position of installation hooks according to the
hook holes on the installation board.
Drill four holes of 12mm, 45~50mm deep at the selected
Ø
positions on the ceiling. Then embed the expansible
hooks (fittings).
Face the concave side of the installation hooks toward the
expansible hooks. Determine the length of the installation
hooks from the height of ceiling, then cut off the
unnecessary part.
If the ceiling is extremely high, please determine the
length of the installation hook according to facts.

Adjust the hexangular nuts on the four installation hooks
evenly, to ensure the balance of the body.
If the drainpipe is awry, leakage will be caused by the
malfunction of the water-level switch.
Adjust the position to ensure the gaps between the body
and the four sides of ceiling are even. The body's lower
part should sink into the ceiling for 10~12 mm (Refer to
Fig.1-4) .
In general, L is half of the screw length of the installation
hook. (Refer to Fig.1-4)
Locate the air conditioner firmly by wrenching the nuts
after having adjusted the body's position well. (Refer to
Fig.1-5)
New built houses and ceilings
1 In the case of new built house, the hook can be embedded
in advance (refer to 2 mentioned above). But it should be
strong enough to bear the indoor unit and will not become
loose because of concrete shrinking.
After installing the body, please fasten the installation paper
2
board onto the air conditioner with bolts(M6X12) to
determine in advance the sizes and positions of the hole
opening on ceiling. (Refer to Fig.1-6)
Please first guarantee the flatness and horizontal of
ceiling when installing it.
Refer to 1 mentioned above for others.
3 Refer to 3 above for installation.
