10.2 Indoor Unit
10.2.1 How to Fix Installation Plate
The mounting wall is strong and solid enough to prevent it 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 120mm.
From installation plate left edge to unit's left side
is 170 mm.
From installation plate right edge to unit's right
side is 160 mm.
○
B
: For left side piping, piping connection for liquid should be about 105 mm from this line.
: For left side piping, piping connection for gas should be about 154 mm 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 ø70 mm hole-core drill.
10.2.2 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
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.
4
Finish by sealing the sleeve with putty or caulking compound at the
final stage.
Put measuring tape at position as shown in the diagram above. The hole centre is
obtained by measuring the distance namely 178.5 mm and 161 mm for left and right hole
respectively.
Drill the piping plate hole at either the right or left and the hole should be slightly slanted
to the outdoor side.
