3. SELECTION OF INSTALLATION LOCATION
When unpacking and moving the indoor unit after unpacked, do not apply force to the piping (refrig-
erant 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 remarkably 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.
NOTE
•
If there is extra space required for * part, servicing can be conducted more easily if 200mm or more is
secured.
CAUTION
•
Install the indoor and outdoor units, power supply wiring ,remote controller wiring and transmission wiring
at least 1 meter away from televisions or radios to prevent image interference or noise. (Depending on the
radio waves, a distance of 1 meter may not be sufficient to eliminate the noise.)
•
Install the indoor unit as far as possible from fluorescent lamps. If a wireless remote controller kit is
installed, the transmission distance may be shorter in a room where an electronic lighting type (inverter or
rapid start type) fluorescent lamp is installed.
(2) Use hanging bolts for installation.
Investigate if the installation place can withstand the mass of the indoor unit and, if necessary, hang the
indoor unit with bolts after it is reinforced by beams etc. (Refer to the installation pattern paper (5) for the
mounting pitch.)
(3) Ceiling height
This indoor unit can be installed up to 4.3m (for 32·63 model, 3.5m) of the ceiling.
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.
