• Do not install the unit in excessive oil fume area such as

kitchen, workshop and etc.

• 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 [piping length for additional gas],

additional refrigerant should be added as shown in the table.

Example: For C18JKD
If the unit is installed at 10 m distance, the quantity of additional 
refrigerant should be 50 g .... (10-7.5) m x 20 g/m = 50 g

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

The centre of installation plate should be at more than   at
right and left of the wall.
The distance from installation plate edge to ceiling should more

than .

From installation plate left edge to unit’s left side is  .

From installation plate right edge to unit’s right is  .
B : For left side piping, piping connection for liquid should be 

about   from this line.

: For left side piping, piping connection for gas should be 

about   from this line.

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

more (at least 5 screws).
(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.

• Putting measuring tape at position as shown in the

diagram above. The hole center is obtained by
measuring the distance namely 128 mm for left and right
hole respectively. Another method is intersection point of
arrow mark extension. The meeting point of the
extension arrow mark is the hole center position.

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

hole should be slightly slanting to the outdoor side. (refer
to step 3)

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.

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