CAUTION
When the outdoor unit is installed in a place
where the drain water might cause any
problems, Seal the water leakage point tightly
using a silicone adhesive or caulking compound.
• When the outdoor unit is to be installed in an elevated
position, be sure to secure its feet.
• If the outdoor unit is to be mounted on a wall, make sure
the base plate supporting it is sturdy enough.
• The base plate should be designed and manufactured to
maintain its strength over a long period of time, and
sufficient consideration should be given to ensure that the
outdoor unit will not fall.
• When the outdoor unit is installed in a place that is always
exposed to strong wind such as a coastal area or on a
high story of a building, secure the normal fan operation
using a duct or a wind shield.
• Especially in windy areas, install the unit in such a way as
to prevent the admission of wind.
• When the outdoor unit is to be mounted high on a wall,
take particular care to ensure that parts do not fall, and
that the installer is protected.
• When doing installation work at ground level, it is usual to
make wiring and pipe connections to the indoor units first,
and then to make connections to the outdoor units.
However, if outdoor work is difficult, you can change the
procedure.
For example, by making adjustments to the wiring and
piping lengths on the inside (rather than the outside).
Precautions for Installation
Necessary Space for Installation
If you need to install the outdoor unit in a location where
there are some obstructions or a wall, secure sufficient
space as shown in the figure below. The cooling effect may
be reduced by 10%.

15 mm.
• Install the outdoor unit at ground level.
• Attach the vibration-proof rubber pads under the fixing legs.
