1.Install the main body
A. The existing ceiling (to be horizontal)
• Please cut a quadrangular hole of 880 880mm in
the ceiling according to the shape of the
installation paper board. (Refer to Chart3, 4)
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.
• Please 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.
If the ceiling is extremely high, please determine
the length of the installation hook according to
facts.
The length could be calculated from Chart5
Length=H-181+L(in general, L=100mm and is half
of the whole length of the installation hook)
• Please 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 chart 5).
Locate the air conditioner firmly by wrenching the
nuts after having adjusted the body's position well.
