13. INDOOR UNIT INSTALLATION
13.1 INSTALLATION OF MAIN BODY
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.
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, drain pipe and cables.
To balance the ceiling and to avoid
vibration, please enforce the ceiling
when necessary.
2) Select the position of installation hooks according to the hook holes on the
installation board.
Drill four holes of ø12mm, 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.
If the ceiling is extremely high, please determine the length of the installation hook
according to facts.
3) Adjust the hexangular nuts on the four
installation hooks evenly, to ensure the
balance of the main body.
If the drain pipe 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.
In general, L is half of the screw length
of the installation hook.
Locate the air conditioner firmly by
wrenching the nuts after having
adjusted the body's position well.
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.
2) 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.
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.
4) Remove the installation paper board.
