SELECTION OF INSTALLATION LOCA-
TION
Hold the hangers at 4 places to move the indoor unit when
unpacking or after unpacked, and do not apply force to the
piping (refrigerant and drain) and resin parts.
(1) Select the installation location that meets the following
conditions and get approval of the customer.
•
Where the cool and warm air spreads evenly in the room.
•
Where there is no obstacles in the air passage.
•
Where drainage can be ensured.
•
Where the ceiling lower surface is not inclined.
•
Where there is sufficient strength to withstand the mass
of the indoor unit (if the strength is insufficient, the indoor
unit may vibrate and get in contact with the ceiling and
generate unpleasant chattering noise).
•
Where a space sufficient for installation and service can
be ensured.
(Refer to Fig. 1 and Fig. 2)
•
Where the piping length between the indoor and the out-
door units is ensured within the allowable length. (Refer
to the installation manual attached to the outdoor unit.)
