2
Choose on before hand the path along which the unit is to be
brought in.
Move this unit as originally package as possible.

4
When lifting the unit , always use protectors to prevent belt
damage and pay attention to the position of the unit's centre
of gravity.
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 reauirements:
There is enough room for installation and maintenance.
The ceiling is horizontal, 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 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.)
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)

5.3.1 Install the main body(cassette type
heat pump)
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.
(Refer to Fig.5-2)
The center of the hole should be at the same position of
that of the heat pump 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
Ø
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 (Refer to
Fig.5-6).
In general, L is half of the screw length of the installation
hook.(Refer to Fig.5-6)
Locate the heat pump firmly by wrenching the nuts after
having adjusted the body's position well.(Refer to 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 heat pump 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.
CAUTION
After installing the body, the four bolts(M6x12)must be
fastened to the heat pump onto ensure the body is
grounded well.
12mm, 45~50mm deep at the selected
