ELECTING INSTALLATION SITE
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.
- The equipment is not intended for use in a potentially
explosive atmosphere.
- Places where servicing space can be well ensured.
- Places where the 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 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 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) in order to avoid the drainwater
dripping. (See figure).

Selecting a location in cold climates

Refer to "Model" on page 3.
To prevent exposure to wind, install the unit with its suction side
facing the wall.
Never install the 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 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).
P
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.

CAUTION
When operating the unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.
1 Construct a large canopy.
2 Construct a pedestal.
Install the unit high enough off the
ground to prevent burying in snow.
