NOTE
Make sure there is enough space to do the
installation.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 .(in
Fig:6-3)
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 plate
(field supply) (about 100mm, on the
underside of the unit) in order to avoid
drain water dripping. (See the picture in
the right).

5.1 Selecting a location in cold
climates
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.
5.2 Prevent sunshine
As the outdoor temperature is measured via the outdoor
unit air thermistor, make sure to install the outdoor unit in
the shade or a canopy should be constructed to avoild
direct sunlight, so that it is not influenced by the sun's
heat, otherwise protection may be possible to the unit.
WARNING
Uncovered scene, anti-snow shed must be
installed: (1) to prevent rain and snow from hitting
the heat exchanger, resulting in poor heating
capacity of the unit, after long time accumulation,
the heat exchanger freezes; (2)To prevent the
outdoor unit air thermistor from being exposed to
the sun ,resulting in failure to boot; (3)To prevent
freezing rain.
