Install a baffle plate on the air suction side of the outdoor unit
and set the outlet side at a right angle to the direction of the
wind:
Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).
If you install the unit on a frame, please install a waterproof plate
(field supply) within 150 mm of the underside of the unit in order
to prevent the invasion of water from the lower direction.
When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
If you install the unit on a building frame,
please install a waterproof plate (field
supply)(within 150 mm of the underside of
the unit) or use a drain kit in order to avoid
the drainwater dripping (field supply). (See
figure).
Make sure that the unit is installed level.
5.2.
Selecting a location in cold climates
To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
Never install the outdoor unit at a site where the suction side
may be exposed directly to wind.
To prevent exposure to wind, install a baffle plate on the air
discharge side of the outdoor unit.
In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit and set the
outlet side at a right angle to the direction of the wind:

Precautions on installation
6.1.
Foundation work
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.
Fix the outdoor unit to the foundation bolts using nuts
with resin washers (1) as shown in the figure.
If the coating on the fastening area is stripped off, the nuts rust
easily.
