Wheater Dependent Precautions; Selecting An Outdoor Location In Cold Climates; Place Of Installation - Daikin EBHQ006BAV3 Installation Manual

Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location
is selected according the applicable legislation.
Although the noise produced by the unit during operation is low,
avoid installation near to places where even low noise levels can
be disturbing (e.g., bedroom windows, terraces, next-door
neighbours).
Do not install the unit in places often used as workplace.
In case of construction works (e.g. grinding works) where a lot of
dust is created, the unit must be covered.
Be sure that sufficient precautions are taken, in accordance with
relevant local laws and regulations, in case of refrigerant
leakage.

Wheater dependent precautions

Select a place where the rain can be avoided as much as
possible.
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, Be sure that the heat exchanger coil is not
affected by the snow (if necessary construct a lateral canopy).
Ensure that water cannot cause any damage to the location by
adding water drains to the foundation and prevent water traps in
the construction.
Do not install the unit in areas where the air contains high levels
of salt such as that near the ocean, corrosion may shorten the
life of the unit.
Prevent direct exposure to winds coming from the sea.
Be sure that the air inlet and outlet of the unit are not positioned
towards the main wind direction. frontal wind will disturb the
operation of the unit. If necessary, use a screen to block the wind.
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 cause 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.

Selecting an outdoor location in cold climates

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.
When installing the unit in a place frequently exposed to snow,
pay special attention to the following:
-
-

Place of installation

Prepare a water drainage channel around the outdoor unit, to
drain waste water from around the unit.
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).
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.
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).
Installing near a wall or obstacle
-
-
Do not sit or stand on top of the unit.
Do not place any objects or equipment on top of the unit.
Strong wind
NOTICE
When operating the unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.
Elevate the foundation as high as possible.
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).
Construct a large canopy.
Construct a pedestal.
Install the unit high enough off the ground
to prevent burying in snow.
NOTICE
Units cannot be installed hanging from the ceiling or
stacked.
Where a wall or other obstacle is in the path of the unit's air
intake or exhaust airflow, the distances as indicated on the
figures below need to be respected.
The wall height on the exhaust side should be 1200 mm or
less.
