6.2. Weather dependent precautions

Select a place where the rain can be avoided as much as
possible.
Since drain flows out of the outdoor unit, do not place anything
under the unit which must be kept away from moisture.
Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in
the construction.
1 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 5.9 inch (150 mm)).
2 If you install the unit on a frame, please install a waterproof plate
within 5.9 inch (150 mm) of the underside of the unit in order to
prevent the invasion of water from the lower direction.
3 If you install the unit on a building frame,
please install a waterproof plate within
5.9 inch (150 mm) of the underside of the
unit in order to avoid the drainwater
dripping.
When installing the unit in a place exposed to strong wind, pay
special attention to the following:
1 Strong winds of 16.40 ft/sec (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.
2 Refer to the figure below for installation of this unit in a place
where the wind direction can be foreseen.
Install a baffle plate on the air discharge side of the outdoor unit:

NOTE Mind the restrictions: refer to "6.4. Installing near a wall
or obstacle" on page 5
Set the outlet side at a right angle to the direction of the wind.

6.3. Selecting a location in cold climates

NOTE When operating the unit in a low outdoor ambient
temperature, be sure to follow the instructions
described below.
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 outdoor unit.
NOTE Mind the restrictions: refer to "6.4. Installing near a wall
or obstacle" on page 5
In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit:
1 Construct a large canopy.
2 Construct a pedestal.
Install the unit high enough off the ground to prevent burying
in snow.

6.4. Installing near a wall or obstacle

Where a wall or other obstacle is in the path of the outdoor unit
air intake or exhaust airflow, follow the installation guidelines
below.
For any of the installation patterns below, the wall height on the
exhaust side should be 47.24 inch (1200 mm) or less.
