enough to bear the indoor unit and will not become loose
because of concrete shrinking.
After installing the body, please fasten the installation paper
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. 4-5)
Please first guarantee the flatness and horizontal of ceiling when
installing it.
Refer to 1 mentioned above for others.

The existing ceiling (to be horizontal)
Cut a quadrangular hole of 880x880mm in the ceiling according
to the shape of the installation paper board.
(refer to
Fig. 4-4, Fig. 4-6 and Fig. 4-7
)
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.
Adjust the hexangular nuts on the four installation hooks
evenly, to ensure the balance of the body.
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
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.
