5. INDOOR UNIT INSTALLATION
5.1 Installation place
(refer to fig.5-1,fig.5-2,fig.5-3 and table 5-1 for specification.)
The indoor unit should be installed in a location that meets
the following requirements:
There is enough room for installation and maintenance.
The ceiling is horiztal, and its structure can endure the
weight of the indoor unit.
The outlet and the inlet are not impeded, and the influence
of external air is the least.
The air flow can reach throughout the room.
The connecting water pipe and drainpipe could be
extracted out easily.
There is no direct radiation from heaters.
CAUTION
Keep indoor unit, outdoor unit, power supply wiring and
transmission wiring at least 1 meter away from televisions
and radios. This is to prevent image interference and
noise in those electrical appliances. (Noise may be
generated depending on the conditions under which the
electric wave is generated, even if 1 meter is kept.)
Before installing the unit,be sure to confirm with the user
whether there are wires,water pipes,air pipes and so on in
the wall or ground of the installation site to avoid accidents
due to damage.
5.2 Installation procedures for fresh air
intake duct connection
Preparing the connection hole
•
Cut off the knockout hole on the side plate with a nipper.
• Cut the inner insulation of the hole portion with a cutter.
(refer to fig.5-4)
Placing the insulation
•
Put the insulation tightly around the hole of the unit as
shown.
The ends of the side plate and the inner insulation must be
completely adhered without leaving any clearance along the
circumference of the hole.
Make sure the inner surface of insulation tightly contacts the
inner insulation edge and the side plate. (refer to fig.5-5)

5.3 Install the 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,
drainpipe 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
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 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
fig.5-6) .
In general, L is half of the screw length of the installation
hook.(refer to fig.5-6)
Locate the air conditioner firmly by wrenching the nuts
after having adjusted the body's position
fig.5-7)
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.5-8)
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.
After installing the body, the four bolts(M6x12)must be
fastened to the air conditioner onto ensure the body is
grounded well.
