In case of strong wind and the wind direction can be
foreseen,refer to the figures below for installation of the
unit(any one is OK):
Turn the air outlet side toward the building's wall, fence
or screen.
Unit
5~9kW
12~16kW
Make sure there is enough space to install the unit.
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.
If water does not easily drain from the unit, mount the
unit on a foundation of concrete blocks, etc. (The
height of the foundation should be about 100 mm
(3.93 in).
If you install the unit on a frame, please install a
waterproof plate (about 100 mm) on the underside of
the unit to prevent water from coming in from the low
side.
When installing the unit in a place frequently exposed
to snow, pay special attention to elevate the
foundation as high as possible.

If you install the unit on a building
frame, please install a waterproof
tray (field supply) (about 100mm, on
the underside of the unit) in order to
avoid drain water dripping. (See the
picture in the right).

Refer to "Handling" in section "4 BEFORE INSTALLATION"
NOTE
When operating the unit in cold climates, 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 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).
① Construct a large canopy.
② Construct a pedestal.
Install the unit high enough off the ground to prevent
it from being buried in snow. （The height of the
pedestal must be larger than the largest thickness of
the snow in the local history plus 10cm or more）
As the outdoor temperature is measured via the unit's
ambient temperature sensor, make sure to install the unit
in the shade or under a canopy to avoild direct sunlight,
so that it is not influenced by the sun's heat, otherwise
the unit may be protected.
