• In the upper space (including the back of the ceiling) of
the indoor unit where there is no possible dripping of
water from the refrigerant pipe, drain pipe, water pipe,
etc.
• If supporting structural members are not strong enough
to take the unit’s weight, the unit could fall out of place
and cause serious injury.
• Where the false ceiling is not noticeably on an incline.
• Where there is no risk of flammable gas leakage.
• Where sufficient clearance for maintenance and service
can be ensured.
• Where piping between indoor and outdoor units is possi-
ble within the allowable limit. (Refer to the installation
manual for the outdoor unit.)
CAUTION
• Install the indoor and outdoor units, power supply wiring and
connecting wires at least 1 meter away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient enough to eliminate the noise.)
• Install this unit where the height of bottom panel is more
than 2.5 m so that the user cannot easily touch.
[ PRECAUTION ]
If installing the wireless kit in a room with electronic fluores-
cent lighting (inverter or rapid start type), the remote con-
troller’s transmission distance may be shortened. Indoor
units should be installed as far away from fluorescent light-
ing as possible.
(2) Use suspension bolts for installation. Check whether
the ceiling is strong enough to support the weight of
the unit or not. If there is a risk, reinforce the ceiling
before installing the unit.
(Installation pitch is marked on the paper pattern for installation.
Refer to it to check for points requiring reinforcing.)
