Turn the air outlet side toward the building’s wall, fence or
screen.
■
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.
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 the following:
-
Elevate the foundation as high as possible.
-
Construct a large canopy (field supply).
-
Remove the rear suction grille to prevent snow from
accumulating on the rear fins.
7
The outdoor unit may short circuit depending on its environment,
so use the louvers (field supply).
8
Do not install or operate the unit on locations where air contains
high levels of salt, like e.g. in the vicinity of oceans. (Refer for
further information to the engineering databook).
9
If you install the unit on a building frame,
please install a waterproof plate (within
150 mm of the underside of the unit) or
use a drain plug kit (option) in order to
avoid the drain water dripping.

INSTALLATION
■
Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after

■
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.

The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.
It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc...
In places with weak reception, keep distances of 3 m or
more to avoid electromagnetic disturbance of other
equipment and use conduit tubes for power and
transmission lines.
