ELECTING INSTALLATION SITE
This is a class A product. In a domestic environment this product may
cause radio interference in which case the user may be required to
take adequate measures.
Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
1 Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.
- Places where there is no possibility of flammable gas or
product leak.
- Places where servicing space can be well ensured.
- Places where the indoor and outdoor units' piping and wiring
lengths 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.
Make sure there is enough room to do the installation
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.
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... (See figure 2)
In extreme circumstances you should keep distances of
3 m or more and use conduit tubes for power and
transmission lines.
5. P
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.
