When the installation plate is directly mounted
on the wall
1. Securely
fi
t the installation plate onto the wall by screwing it in the upper
and lower parts to hook up the indoor unit.
2. To mount the installation plate on a concrete wall with anchor bolts, use the
anchor bolt holes as illustrated in the below
fi
gure.
3. Install the installation plate horizontally in the wall.
When installing the installation plate with a mounting screw, do not use
the anchor bolt holes. Otherwise, the unit may fall down and result in
personal injury and property damage.
1. After determining the pipe hole position on the mounting plate (
➡
), drill the
pipe hole (Ø65 mm) at a slight downward slant to the outdoor side.
• A place which provides the spaces around the indoor unit as shown in the
diagram
• A place where there are no obstacles near the air inlet and outlet
• A place which allows easy installation of the piping to the outdoor unit
• A place which allows the front panel to be opened
• The indoor unit shall be installed as top of the indoor unit comes to at least
2 m height. Also, it must be avoided to put anything on the top of the indoor
unit.
