Wall Mounted Type CNH30/36TDB(AC030/036BNTDCH/AA)
Choosing the installation location
Installation location requirements
• There must be no obstacles near the air inlet and outlet.
• Install the indoor unit on a ceiling that can support its weight.
• Maintain sufficient clearance around the indoor unit.
• Before installing the indoor unit, be sure to check whether the
chosen location is well-drained.
WARNING
• Minimum installation height of indoor unit is 0.6 m for floor
mounted, 1.8 m for wall, 2.2 m for ceiling.
CAUTION
Do not install the air conditioner in following places.
• The place where there is mineral oil or arsenic acid. Resin
parts flame and the accessories may drop or water may leak.
The capacity of the heat exchanger may reduce or the air
conditioner may be out of order.
• The place where corrosive gas such as sulfurous acid gas
generates from the vent pipe or air outlet. The copper pipe or
connection pipe may corrode and refrigerant may leak.
• The place where there is a machine that generates
electromagnetic waves. The air conditioner may not operate
normally due to control system.
• The place where there is a danger of existing combustible gas,
carbon fiber or flammable dust.
• The place where thinner or gasoline is handled. Gas may leak
and it may cause fire.
• The place where animals may urinate on the product.
Ammonia may be generated.
• The place where is close to heat sources.

Make a U-trap (A) on the pipe
(which is connected to the indoor

unit) at outer wall and cut the
bottom part of the insulation
[about 0.39 inch (10 mm)] to
prevent rainwater from getting
inside through the insulation.
Drilling a hole through the wall
Before fixing the installation plate to a wall and then fixing the
indoor unit to the installation plate, a window frame, or a gypsum
board, you must determine the position of a hole [with 2.56
inch (65 mm) inner diameter] through which the pipe bundle
(consisting of power and communication cables, refrigerant pipes,
and drain hose) will pass and then drill that hole.
1 Determine the position of a 2.56 inch (65 mm) hole in
consideration of the possible directions of the pipe bundle and
the minimum distances between the hole and the installation
plate.

CAUTION
• If changing the pipe direction from left to right, do not
drastically bent it but slowly turn it in the opposite direction as
shown. Otherwise, the pipe may be damaged in the process.

CAUTION
• Be sure to drill only one hole.
• Make sure that the hole slants downwards so that the drain
hose slants downwards to drain water well.
