12.2.1 How to Fix Installation Plate
The mounting wall is strong and solid enough to prevent if from the vibration.
The centre of installation plate should be at
more than 450 mm at right and left of the wall.
The distance from installation plate edge to
ceiling should more than 67mm.
From installation plate left edge to unit’s left side
is 74mm.
From installation plate right edge to unit’s right
side is 94mm.
: For left side piping, piping connection for liquid should be about 15mm from this line.
○
B : For left side piping, piping connection for gas should be about 45mm from this line.
: For left side piping, piping connection cable should be about 800mm from this line.
1. Mount the installation plate on the wall with 5 screws or more. (If mounting the unit on the 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 ø70mm hole-core drill.
o Line according to the left and right side edge 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 150mm and 125mm for
left and right hole respectively.
o Drill the piping plate hole at either the right or left and the hole should be slightly slanted to the outdoor
side.
12.2.2 To Drill a Hole in the Wall and Install a Sleeve of Piping
1. Insert the piping sleeve to the hole.
2. Fix the busing to the sleeve.
3. Cut the sleeve until it extrudes about 15mm from the wall
4. Finish by sealing the sleeve with putty or caulking compound at the
final stage.
Caution
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.
