Turn the air outlet side toward the building's wall, fence or
screen.
Make sure there is enough room to do the installation
Set the outlet side at a right angle to the direction of the wind.

Blown air
3 Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
4 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).
5 If you install the unit on a frame, please install a waterproof plate
within 150 mm of the underside of the unit in order to prevent the
invasion of water from the lower direction.
6 When installing the unit in a place frequently exposed to snow,
pay special attention to elevate the foundation as high as
possible.
7 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 (refer to
combination table in "Possible options" on
page 3) in order to avoid the drainwater
dripping. (See figure).

Selecting a location in cold climates

Refer to "Model" on page 3.
NOTE When operating the outdoor unit in a low outdoor
ambient temperature, be sure to follow the instructions
described below.
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. 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
1 Construct a large canopy.

2 Construct a pedestal.
Install the unit high enough off
