Selecting A Location In Cold Climates - Airwell AW-WHPMA18-H93 Manual De Instalación

Strong winds of 5 m/sec or more blowing against the unit's air outlet causes a 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 front of the unit, the fan can start rotating very fast until it breaks.
In normal condition,refer to the figures below for install-
ation of the unit:
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.
Make sure there is enough room 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
(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 founda-
tion as high as possible.
If you install the unit on a building
frame, please install a waterproof plate
(field supply) (within 150mm of the
underside of the unit) in order to avoid
drain water dripping. (See the picture in
the right).

6.1 Selecting a location in cold climates

Refer to "Handling" in section "4 Before installation"
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.
