• 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 7.5m, additional refrigerant should be

added as shown in the table.

• Do not install at place where there is direct sunlight or near

any heat source.

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

The centre of installation plate should be at more than 550 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 47 mm.
From installation plate right edge to unit’s right is 73 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 arrows marked on the lower left

and right side of the installation plate. The meeting point
of the extended line is the centre of the hole. Another
method is by putting measuring 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.

1. For the right rear piping

2. For the right and right bottom piping

:

:

:

For left side piping, piping connection for liquid should be
about 126 mm from this line.

For left side piping, piping connection about 174 mm from
this line.

For left side piping, piping connection about 984 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.

3. For the embedded piping

(This can be used for left rear piping and left bottom piping also.)

24

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 

× 2.5 mm

2

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 horizon-

tally 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.
