1.5.1 Selection of location for installation
(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.
(2) Outdoor unit
(a) A place where good air circulation can be obtained.
(b) A place where the exhausted air will not be sucked in for the second time.
(c) A place where the unit will not be affected by other heat sources. (When there are several units installed or another heat
source)

Note (1) If the wall is higher than 1.2 m or a ceiling is
present, distances larger than indicated in the above
table must be provided.
(g) A place where vibration will not be enlarged.
(h) In heating operation, snow deposit on the heat-exchanger of
outdoor unit must be prevented for keeping the normal perfor-
mance capacity.
(i) Snow-hood on outdoor unit as in drawing, will reduce
the frequency of defrost operation.
When installing the snow hood, take care so that the air
outlet of the snow hood will not face directly into the
most windy direction.
(ii) Design the base higher than possible snow deposit.
(3) Limitations for one way piping length and vertical
height difference.
