Installation manual
4
-
Places where lengths of piping and wiring for indoor units, BP
units and outdoor units come within the allowable ranges.
-
Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).
-
Places where the rain can be avoided as much as possible.
2
When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
-
Deterioration of the operational capacity.
-
Frequent frost acceleration in heating operation.
-
Disruption of operation due to rise of high pressure.
-
When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.
■
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.
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 the following:
-
Elevate the foundation as high as possible.
-
Remove the rear suction grille to prevent snow from
accumulating on the rear fins.
7
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 drainwater dripping.

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 4 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.

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 extreme circumstances you should keep distances of
3
m or more and use conduit tubes for power and
transmission lines.
