For authorized service personnel only.
WARNING
SELECTING THE MOUNTING POSITION
WARNING
CAUTION
CAUTION
Hold the torque wrench at its grip, keeping it in the right
angle with the pipe as shown in Fig. 25, in order to tighten
the flare nut correctly.
CAUTION
Be sure to apply the pipe against the port on the indoor
unit correctly. If the centering is improper, the flare nut
cannot be tightened smoothly. If the flare nut is forced to
turn, the threads will be damaged.
WARNING
CAUTION
In order to check the drainage, be sure to use a level dur-
ing installation of the indoor unit. If the installation site of
the indoor unit is not level, water leakage may occur.
WARNING
Install the unit where it will not be tilted by more
than 5
°
.
When installing the outdoor unit where it may
exposed to strong wind, fasten it securely.

The maximum lengths of this product are shown in table 3.
If the units are further apart than this, correct operation
can not be guaranteed.
CAUTION
(1)
For the air conditioner to operate satisfactorily, install it as outlined in this installation manual.
(2)
Installation work must be performed in accordance with national wiring standards by authorized personnel only.
(3)
Do not turn on the power until all installation work is complete.
•
Be careful not to scratch the air conditioner when handling it.
•
After installation, explain correct operation to the customer, using the operating manual.
•
Let the customer keep this installation manual because it is used when the air conditioner is serviced or moved.
Install at a place that can withstand the weight of the
indoor and outdoor units and install positively so that
the units will not topple or fall.
Do not install where there is the danger of com-
bustible gas leakage.
Do not install the unit near a source of heat, steam,
or flammable gas.
If children under 10 years old may approach the unit,
take preventive measures so that they cannot reach
the unit.
Decide the mounting position with the customer as follows:
1. INDOOR UNIT
Install the indoor unit level on a strong wall which is not subject to
vibration.
The inlet and outlet ports should not be obstructed : the air should
be able to blow all over the room.
Do not install the unit where it will be exposed to direct sunlight.
Install the unit where connection to the outdoor unit is easy.
Install the unit where the drain pipe can be easily installed.
Take servicing, etc. into consideration and leave the spaces shown
in (Fig. 2 or 3). Also install the unit where the filter can be removed.

INDOOR UNIT INSTALLATION
PREPARING INDOOR UNIT
INSTALLATION
You can use the accessory template to help you install the indoor
unit. The template helps you determine the appropriate locations for
suspension bolts and pipe openings (drain pipe and connection cord).

1. LOCATION OF CEILING SUSPENSION BOLTS
Fig. 7
[For Half-Concealed Installation]
Suspension-bolt pitch should be as shown in Fig. 7.

2. SELECT PIPING DIRECTION.
Select connection piping and drain piping directions (Fig.9).

Fig. 10
DRILLING THE HOLES AND ATTACHING THE SUS-
PENSION BOLTS
Drill ø25mm holes at the suspension-bolt locations.
Install the bolts, then temporarily attach Special nuts A and B
and a normal M10 nut to each bolt. (The two special nuts are pro-
vided with the unit. The M10 nut must be obtained locally.) Refer
to Fig. 11.
Fig. 11
[If using anchor bolts]
Drill holes for anchor bolts at the locations at which you will set
the suspension bolts. Note that anchor bolts are M10 bolts (to be
obtained locally).
Install the anchor bolts, then temporarily attach special nut "B"
(included) and a locally-procured M10 nut to each of the bolts.
(See Fig. 12.)
Fig. 12
4. INSTALLING THE INDOOR UNIT
Lift unit so that suspension bolts pass through the suspension fit-
tings at the sides (four places), and slide the unit back. (See Fig.
14.)
Fig. 13
Fig. 14
Fasten the indoor unit into place by tightening-up the special “B”
bolts and the M10 nuts. Make sure that unit is secure and will not
shift back and forth.
[For Half-Concealed Installation]
When installing the indoor unit in a semi-concealed orientation, make
sure to reinforce the insulation of the unit on all sides. Drops of water
may fall from the unit if it is not thoroughly insulated.
Fig. 15
2. FLARE PROCESSING
Cut the connection pipe with pipe cutters so that the pipe is not
deformed.
Holding the pipe downward so that cuttings cannot enter the pipe,
remove the burrs.
Remove the flare nut from the indoor unit pipe and outdoor unit
and assemble as shown in (Table 4) and insert the flare nut onto
the pipe, and flare with a flaring tool.
Check if the flared part “L” (Fig. 19) is spread uniformly and that
there are no cracks.

If possible, do not install the unit where it will exposed to direct
sunlight. (If necessary, install a blind that does not interfere with the
air flow.)
Install the outdoor unit in a place where it will be free from being dir-
ty or getting wet by rain as much as possible.
Install the unit when connection to the indoor unit is easy.
During heating operation, drain water flows from the outdoor unit.
Therefore, install the outdoor unit in a place where the drain water
flow will not be obstructed. (Heat & Cool model (Reverse cycle) only)
Do not place animals and plants in the path of the warm air.
Take the air conditioner weight into account and select a place where
noise and vibration are small.
Select a place so that the warm air and noise from the air conditioner
do not disturb neighbors.
Provide the space shown in Fig. 4 so that the air flow is not blocked.
Also for efficient operation, leave open three of the four directions
front, rear, and both sides.

Do not bend the pipes in an angle less than 90
°
.
When the pipes are bent and stretched repeatedly, the material will be
hardened, causing the pipes no longer be sent or stretched. Be sure to lim-
it number of bending and stretchings to three times.
When bending the pipe, do not bend
it as is. The pipe will be collapsed. In
this case, cut the heat insulating pipe
with a sharp cutter as shown in Fig.
21, and bend it after exposing the
pipe. After bending the pipe as you
want, be sure to put the heat insulat-
ing pipe back on the pipe, and secure
it with tape.

When the flare nut is tightened properly by your hand, hold the boby side
coupling with a separate spanner, then tighten with a torque wrench. (Fig. 25)

If this product is used in an area where
the temperature falls below freezing
for long periods of time, do not con-
nect the drain pipe. Instead, allow the
water to drain into a drain pan.
