Installation Conditions
As the unit is heavy, the wall or window of the installation area should
have sufficient strength and durability for operation of the air conditioner,
and for prevention of any vibration or noise.
If it is weak, reinforcement work should be performed separately.
1
It is advisable to install the air conditioner in the north or west side to
prevent the effect of direct sunlight.
When installing it in the south or east side due to unavoidable
circumstances, it is advisable to install the sunshade to prevent the
direct sunlight.
In this case, take care not to cause any hindrance to the flow of outside air.
2
When installing the air conditioner, be sure to obtain sufficient space on
the rear side of the unit for smooth flow of air.
When operating the air conditioner in closed areas such as inner building
with cooling operation, and result in trouble with the unit.
