11.2.1. 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 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 .
B: 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.
