Keep the indoor unit, outdoor unit, power supply wire, and
transmission wire at least 1000 mm away from televisions
and radios. This is to prevent image interference and noise.
(Noise may be generated depending on the conditions under
which the electric wave is generated, even if 1000 mm
distance is maintained.)
5. INDOOR UNIT INSTALLATION
5.1 Installation place
(Refer to Fig.5-1, Fig.5-2, Fig.5-3 for specifications.)
The indoor unit should be installed in a location that
meets the following requirements:
5.2 Install the main body
Cute a quadrangular hole 600×600 mm in the ceiling according
to the shape of the installation paper board.
(Refer to Fig.5-3,Fig.5-4)
The center of the hole should be in the same position the air
conditioner body’s center.
Determine the lengths and outlets of the connection pipe,
drainage pipe and wires.
To balance the ceiling and to avoid vibrations, strengthen the
ceiling if necessary.
Adjust the hexangular nuts on the four installation hooks
evenly to ensure the body is balanced.
If the drainage pipe is faulty, leaks may be caused by a
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 10-12 mm.
(Refer to Fig.5-5)
Use the transparent hose filled with water to check the lever
of the main body from the four sides or diagonal line direction.
The lever indicator can check the lever from the four sides of
the main body. (Refer to Fig.5-6)
Locate the air conditioner firmly by tightening the nuts after
adjusting the body's position well.
Select the position of installation hooks according to the hook
holes on the installation board.
Drill four holes of Ø 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, determine the length of the
installation hook according to facts.
Cut the installation hook open in the middle position, then
use an appropriate length of reinforcing rods (Ø12mm) to
weld it together.
The length can be calculated from (Refer to Fig.5-4):
Length=210 mm+L (In general, L is 30-40mm)

Newly built houses and ceilings
In the case of a newly built house, the hook can be embedded
in advance (Refer to point B mentioned above). But it should
be strong enough to bear the indoor unit and not become
loose because the concrete has shrunk.
After installing the body, fasten the installation paper board
onto the air conditioner with bolts (M5X20) to pre-determine
the sizes and positions of the hole opening on ceiling. (Refer
to Fig.5-8)
Refer to point C mentioned above for installation.
Remove the installation paper board.
Please guarantee the horizontal flatness of the ceiling when
installing it
Refer to point A mentioned above for others.
After installing the body, the four bolts (M6x12) must be
fastened to the air conditioner to ensure the body is
grounded well.
CAUTION
CAUTION
The existing ceiling (to be horizontal)
Not suitable for narrow spaces or areas that are sensitive
to noise.
Ensure that there is enough room for installation and
maintenance.
Ensure the ceiling is horizontal, and its structure can bear
the weight of the indoor unit after cutting any holes or
performing other installation-related work.
The outlet and the inlet must not be impeded and there
must be minimal influence from the outside air.
The air flow extends throughout the room.
The connection pipe and drainage pipe can be extracted
easily.
There is no direct radiation from heaters.
Do not install it in a place where the air contains a lot of
salt. If this can't be avoided, choose an anticorrosive
model.
Reserve a maintenance hole for subsequent maintenance
When installing the unit, leave a maintenance hole beside the
electronic control box in the ceiling in advance for maintenance.
Its dimensions and position are shown in Fig.5-1.
The hole should be sealed by a cover or other decorative materials.
Ensure the cover of the hole can be disassembled when the indoor
unit needs maintenance.
