connections are owner’s responsibility.
2- Failure due to Misuse, Abusing, overloading, negligence of air filters cleaning and
negligence of instructions included in the owner’s manual.
3- Failure due to Accident / Weather Natural catastrophe, accident due to bad weather
(Hail Storm, Sand Storm, lightning, Flooding, Acid Rain and Air Borne fallout, etc).
4- Failure due to damages during transport done through the owner.
5- Failure due to any modifications in the product done through the owner.
6- Failure due to Installation or Service and Maintenance or repair works
done through the owner.

SELECTING INSTALLATION LOCATION OF OUTOOR UNIT (Cont.)
CONSIDERATIONS FOR SELECTING INSTALLATION LOCATION (Cont.)
Select the installation location of outdoor unit which is able to support operating weight
of outdoor unit, and not cause vibration.
Select the installation location of outdoor unit which is far away from the direct
sunlight.
Select the installation location of outdoor unit which is far away from heat sources,

When the installation is made on the rooftop or other places subject to strong wind :
When the outdoor unit is to be installed on the rooftop or at the places where there are no other
buildings around. it is required to avoid the strong wind from blowing directly into the air outlet of the
outdoor unit so as to prevent the negative impacts on cooling or heating performances due to
insufficient airflow of the outdoor unit heat exchanger and to prevent from faulty performances.
When there are walls in the vicinity, the air outlet
should face the wall and keep a space of 500mm
from the wall.
When the air outlet is affected by the strong wind,
the installation position should be changed so as
to make the air outlet at a straight angle from the
wind direction.
