11.3.1. 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 67 mm.
From installation plate left edge to unit’s left side is 74 mm.
From installation plate right edge to unit’s right is 94 mm.
1. Mount the installation plate on the wall with 5 screws or
more.
(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
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 150 mm and 125 mm for left and right
hole respectively.
• Drill the piping hole at either the right or the left and the
hole should be slightly slanted to the outdoor side.
11.3.2. TO DRILL A HOLE IN THE WALL
AND INSTALL A SLEEVE OF
PIPING
1. Insert the piping sleeve to the hole.
2. Fix the 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.
11.3.3. INDOOR UNIT INSTALLATION
1. For the right rear piping
2. For the right and right bottom piping
: For left side piping, piping connection for liquid should be about
15 mm from this line.
: For left side piping, piping connection for gas should be about
45 mm from this line.
: For left side piping, piping connection cable should be about
800 mm from this line.
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.
