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

tion.

• 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 485 mm
at right and left of the wall.
The distance from installation plate edge to ceiling should more
than 75mm.
From installation plate left edge to unit's left side is 75 mm.
From installation plate right edge to unit's right is 85 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 align-

ing 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 107 mm and 58 mm for left and right edge of the
installation plate 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. Cut the sleeve until it extrudes about 15 mm from the

wall.

3. Fix the bushing to the sleeve.
4. Finish by sealing the sleeve with putty or caulking com-

pound at the final stage.

Carry out work carefully not to scratch the surface of the mobile panel.

For left side piping, piping connection for liquid should be
about 5 mm from this line.

For left side piping, piping connection for gas should be
about 55 mm from this line.

For left side piping, piping connection cable should be
about 750 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.
