that the panel is level. This is important to install the unit 
properly. (Fig. 3-3)

CAUTION
Also avoid areas where electrical wiring or conduits are 
located.
The above precautions are also applicable if tubing goes 
through the wall in any other location.
(4)  Using a sabre saw, keyhole saw or hole-cutting drill 
attachment, cut a hole in the wall. (Fig. 3-4)

3-3. To Drill a Hole in the Wall and Install a Piping 
sleeve
(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.
CAUTION
When the wall is hollow, please be sure to use the Piping 
sleeve assembly to prevent dangers caused by mice biting the 
connection cable.
(4)  Finish by sealing the sleeve with putty or caulking 
compound at the final stage.

Tubing can be extended in 6 directions as shown in Fig. 3-1. 
Select the direction you need providing the shortest run to the 
outside unit.

The center of installation plate should be at more than 1 at 
right and left of the wall.
The distance from installation plate edge to ceiling should be 
more than 2.
From installation plate center to unit’s left side is 3.
From installation plate center to unit’s right side is 4.
For left side piping, piping connection for liquid should be about 
5 from this line.
For left side piping, piping connection for gas should be about 
6
 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) Drillthepipingplateholewithø70mmhole-coredrill.
●  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.
● Drillthepipingholeateithertherightortheleftand
the hole should be slightly slanting to the outdoor side.
