• There should not be any heat source or steam near the unit.
• There should not be any obstacles blocking the air

circulation.

• A place where air circulation in the room is good.
• A place where drainage can be easily done.
• A place where noise prevention is taken into consideration.
• Do not install the unit near the door way.
• Ensure the spaces indicated by arrows from the wall, ceiling,

fence or other obstacles.

• Recommended installation height for indoor unit shall be at

least 2.5 m.

• If an awning is built over the unit to prevent direct sunlight or

rain, be careful that heat radiation from the condenser is not
obstructed.

• There should not be any animal or plant which could be

affected by hot air discharged.

• Keep the spaces indicated by arrows from wall, ceiling,

fence or other obstacles.

• Do not place any obstacles which may cause a short circuit

of the discharged air.

• If piping length is over the rated length, additional refrigerant

should be added as shown in the table.

• This illustration is for explanation purposes only.

The indoor unit will actually face a different way.

The mounting wall is strong and solid enough to prevent it from
the vibration.

The centre of installation plate should be at more than 450 mm
at right and left of the wall.
The distance from installation plate edge to ceiling should more
than 67 mm.
From installation plate left edge to unit's left side is 74 mm.
From installation plate right edge to unit's right is 94 mm.

1. Mount the installation plate on the wall with 5 screws or

more.
(If mounting the unit on the concrete wall, consider using
anchor bolts.)

• Always mount the installation plate horizontally by

aligning the marking-off line with the thread and using a
level gauge.

2. Drill the piping plate hole with ø70 mm hole-core drill.

• Line according to the left and right side edge of the instal-

lation plate. The meeting point of the extended line is the
centre of the hole. Another method is by putting measur-
ing tape at position as shown in the diagram above. The
hole centre is obtained by measuring the
distance namely 150 mm and 125 mm for left and right
hole respectively.

• Drill the piping hole at either the right or the left and the

hole should be slightly slanted to the outdoor side.

1. Insert the piping sleeve to the hole.
2. Fix the bushing to the sleeve.
3. Cut the sleeve until it extrudes about 15 mm from the

wall.

4. Finish by sealing the sleeve with putty or caulking

compound at the final stage.

:

For left side piping, piping connection for liquid should be
about 15 mm from this line.

For left side piping, piping connection for gas should be
about 45 mm from this line.

For left side piping, piping connection cable should be
about 800 mm from this line.

When the wall is hollow, please be sure to use the sleeve for tube
ass’y to prevent dangers caused by mice biting the connecting cable.

• How to pull the piping and drain hose out, in case of the

embedded piping.

• In case of left piping how to insert the connecting cable and

drain hose.

1. The inside and outside connecting cable can be

connected without removing the front grille.

2. Connecting cable between indoor unit and outdoor unit

shall be approved polychloroprene sheathed 3 (C7GK,
C9GK, C12GK, RS-C7GK, RS-C9GK, RS-C12GK) or 5

(A9GK, A12GK) × 1.5mm

 flexible cord, type designation

245 IEC 57 or heavier cord.

• Ensure the colour of wires of outdoor unit and the

terminal Nos. are the same to the indoor’s respectively.

• Earth lead wire shall be longer than the other lead wires

as shown in the figure for the electrical safety in case of
the slipping out of the cord from the anchorage.

• Secure the cable onto the control board with the holder

(clamper).

• After selecting the best location, start installation according

to Indoor/Outdoor Unit Installation Diagram.

1. Fix the unit on concrete or rigid frame firmly and

horizontally by bolt nut (ø10 mm).

2. When installing at roof, please consider strong wind and

earthquake. Please fasten the installation stand firmly
with bolt or nails.

Connecting The Piping To Indoor Unit
Please make flare after inserting flare nut (locate at joint portion
of tube assembly) onto the copper pipe. (In case of using long
piping)
Connect the piping

• Align the center of piping and sufficiently tighten the flare nut

with fingers.

• Further tighten the flare nut with torque wrench in specified

torque as stated in the table.
