(1) Indoor unit
(a) Where there is no obstructions to the air flow and where the
cooled air can be evenly distributed.
(b) A solid place where the unit or the wall will not vibrate.
(c) A place where there will be enough space for servicing. (Where
space mentioned below can be secured)
(d) Where wiring and the piping work will be easy to conduct.
(e) The place where receiving part is not exposed to the direct rays of the sun or the strong rays of the street lighting.
