INDOOR UNIT INSTALLATION
1. Install the main body
A. The existing ceiling (to be horizontal)
a. Please cut a quadrangular hole of 880X880mm in the ceiling according to the shape of the installation
paper board. (Refer to Chart 3, 4)
•
The center to 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.
b. Please select the position of installation hooks according to the hook holes in the installation board.
•
Drill four holes of M12mm, 45-50mm deep at the selected positions on the ceiling. Then embed the
expansible hooks (fittings).
•
Face the concave side of the installation hooks towards the expansible hooks. Determine the length
of the installation hooks from the height of ceiling, then cut off the unnecessary part.
The length could be calculated from Chart 5:
Length= H-181+L ( in general, L=100mm and is half of the whole length of the installation hook)
c. Please adjust the hexangular nuts on the four installation hooks evenly, to ensure the balance of the
body.
•
If the drainpipe is away, 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 10-12mm (Refer to Chart 5).
•
Location the air conditioner firmly by wrenching the nuts after having adjusted the body’s position
well.
