∙ If there is any unavoidable reason to install the unit at such
a place, take the following measures:
– When installing the unit at a roadside concentrated with
buildings, install it parallel to the road.
– Install the unit so that the air outlet faces the wall such as
rooftop that may be subjected to strong wind.
∙ When installing the outdoor unit near the seashore, make
sure that it is not directly exposed to sea breeze. If you
cannot find an adequate place, a protection wall should
be constructed.

∙ Construct a protection wall made of solid material
such as concrete to block sea breeze. Make sure that

the outdoor unit for exhausted air to ventilate.
∙ Install the unit at a place where water can drain smoothly.
∙ If you have any difficulty in finding an installation
location, contact your manufacturer.
