circulator.
2) Where there are no wind disturbances to the suction inlet and blowing outlet, where the fire alarm will not be set off
erroneously, where no short circuits occur.
3) Where there is no obstructions to the air flow and where the cooled air can be evenly distributed.
4) A solid place where the unit or the wall will not vibrate.
5) A place where there will be enough space for servicing.
(Where space mentioned below can be secured)
6) Where wiring and the piping work will be easy to conduct.
7) The place where receiving part is not exposed to the direct rays of the sun or the strong rays of the street illumination.
8) When a sufficient interval cannot be secured between the unit and a wall or another unit, shut up diffusers on that side to
block winds and make sure that no short-circuiting is occurring.
(A wind blocking material is available as an optional part)
