In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit. If lateral
snowfall is possible, make sure that the heat exchanger coil is
not affected by the snow (if necessary construct a lateral
canopy).

RECAUTIONS ON INSTALLATION
Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)
It is best to screw in the foundation bolts until their length are
20 mm from the foundation surface.

Drain work
Check in the combination table under "Possible options" on page 3
whether drain work is allowed. In case drain work on your unit is
allowed and the installation site requires drain work, then follow the
guidelines below.
Drain kits for drainage are available as option.
If drain work from the outdoor unit causes trouble (for example, if
the drain water may splash on people) provide the drain piping
using a drain socket (optional).
Make sure the drain works properly.
NOTE
If drain holes of the outdoor unit
are covered by a mounting base
or by floor surface, raise the unit
in order to provide a free space
of more than 100 mm under the
outdoor unit.
