INSTALLATION INSTRUCTION SHEET
(PART NO. 9366379027)
For authorized service personnel only.
WARNING!
CAUTION!
1 For the air conditioner to operate satisfactorily, install it as outlined in this installation instruction sheet.
2 Connect the indoor unit and outdoor unit with the room air conditioner piping and cords available from our
standard parts. This installation instruction sheet describes the correct connections using the installation set
available from our standard parts.
3 Installation work must be performed in accordance with national wiring standards by authorized personnel only.
4 If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant comes in contact with a
flame, it produces a toxic gas.
5 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 instruction sheet because it is used when the air conditioner is serviced or moved.
•
The maximum length of the piping is shown in Table 1. If the units are further apart than this, correct operation
cannot be guaranteed.

INSTALLING DRAIN PIPE
CAUTION
Install the drain pipe in accordance with the instructions
in this installation instruction sheet and keep the area
warm enough to prevent condensation. Problems with
the piping may lead to water leaks.
NOTE: Install the drain pipe.
•
Install the drain pipe with downward gradient (1/50 to 1/100) and so
there are no rises or traps in the pipe.
•
Use general hard polyvinyl chloride pipe (VP25) [outside diameter 11/4” (32 mm)] and connect it with adhesive (polyvinyl chloride) so that
there is no leakage.
•
When the pipe is long, install supporters.
•
Do not perform air bleeding.
•
Always heat insulate the indoor side of the drain pipe.
•
When desiring a high drain pipe height, raise it up to 31” (800 mm) or
less from the ceiling within a range of 6” (150 mm) from the body. A
rise dimension over this range will cause leakage.

When the outdoor unit will be exposed to strong wind, fasten it with bolts
or wire at the four places indicated by the arrows (Fig. 21, 22).

CAUTION
If this product is used in an area where
the temperature falls below freezing
for long periods of time, do not connect the drain pipe. Instead, allow the
water to drain into a drain pan.
CONNECTING THE PIPING
1. FLARE PROCESSING
(1)
Cut the connection pipe with pipe cutters so that the pipe is not
deformed.
(2)
Holding the pipe downward so that cuttings cannot enter the pipe
and remove the burrs.
(3)
Remove the flare nut from the indoor unit pipe and outdoor unit
and assemble as shown in (Table 3) and insert the flare nut onto
the pipe, and flare with a flaring tool.
(4)
Check if the flared part “L” (Fig. 25) is spread uniformly and that
there are no cracks.

2. BENDING PIPES
The pipes are shaped by your hands. Be careful not to collapse them.
Fig. 26
Do not bend the pipes in an angle more than 90°.
When pipes are repeatedly bent or stretched, the material will harden,
making it difficult to bend or stretch them any more. Do not bend or
stretch the pipes more than 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.
27, and bend it after exposing the
pipe. After bending the pipe as you
want, be sure to put the heat insulating pipe back on the pipe, and secure
it with tape.
CAUTION
To prevent breaking of the pipe, avoid sharp bends.
1
Bend the pipe with a radius of curvature of 150 mm or
over.
If the pipe is bent repeatedly at the same place, it will
2
break.

INSTALLATION PROCEDURE
Install the air conditioner as follows:
INDOOR UNIT INSTALLATION
WARNING
Install the air conditioner in a location which can with-
•
stand a load of at least five times the weight of the main
unit and which will not amplify sound or vibration.
If the installation location is not strong enough, the indoor unit may fall and cause injuries.
If the job is done with the panel frame only, there is a risk
•
that the unit will come loose. Please take care.
REMOVING THE INTAKE GRILLE
(1)
Push the intake grille pushbuttons (two places).
(2)
Open the intake grille.

flare nut cannot be tightened smoothly. If the flare nut
is forced to turn, the threads will be damaged.
2
Do not remove the flare nut from the indoor unit pipe
until immediately before connecting the connection
pipe.
When the flare nut is tightened properly by your hand, hold the body
side coupling with a separate spanner, then tighten with a torque
wrench (Fig. 29).

SELECTING THE MOUNTING POSITION
Especially, the installation place is very important for the split type air
conditioner because it is very difficult to move from place to place after the first installation.
Decide the mounting position together with the customer as follows:

exposed to strong wind, fasten it securely.
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
dirty 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.
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.
Remove the grille hinge wire.

the two parts (large and small) of the indoor unit coupling, using the
coupler heat insulation.
After installing the coupler heat insulation, wrap both ends with vinyl
tape so that there is no gap.

ELECTRICAL WIRING
HOW TO CONNECT WIRING TO THE TERMINALS
A. For solid core wiring (or F-cable)
(1)
Cut the wire end with a wire cutter or wire-cutting pliers,
then strip the insulation to about 15/16” (25 mm) to expose
the solid wire.
(2)
Using a screwdriver, remove the terminal screw(s) on the
terminal board.
(3)
Using pliers, bend the solid wire to form a loop suitable for
the terminal screw.
(4)
Shape the loop wire properly, place it on the terminal
board and tighten securely with the terminal screw using a
screwdriver.

POWER
WARNING
The rated voltage of this product is 220-240 V 50 Hz.
1
Before turning on verify that the voltage is within the
2
198 to 264 V range.

positively.
Install a leakage special branch circuit breaker in ac-
6
cordance with the related laws and regulations and
electric company standards.
CAUTION
When the voltage is low and the air conditioner is difficult
to start, contact the power company the voltage raised.
