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

The center 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  .

: 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.

• Line according to the left and right side of the installation

plate. The meeting point of the extended line is the
center of the hole. Another method is by 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.

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

hole should be slightly slanting 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.
