3. SELECTION OF INSTALLATION LOCATION
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 cus-
tomer.
•
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 outdoor units is ensured within the allowable length.
(Refer to the installation manual attached to the outdoor unit.)
•
Where there is no risk of flammable gas leak.
[Required installation space[mm]]
∗
: Sufficient service space is required for removing the corner cover. (NOTE 2)
In addition to the general usage, since the items in the operation manual with the
WARNING and
CAUTION marks are likely to result in human bodily injuries and property damages, it is neces-
sary not only to explain these items to the customer but also to have the customer read them.
It is also necessary to explain the items of “NOT MALFUNCTION OF THE AIR CONDITIONER” to the
customer and have the customer read them carefully.
