CAUTION
• Install the indoor and outdoor units, power supply wiring and
connecting wires at least 3.3 ft (1 m) away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.3 ft (1 m) may
not be sufficient enough to eliminate the noise.)
• In the case of the installation of the wireless remote controller,
the transmission distance of the wireless remote controller may
be shortened if the room has a fluorescent light of electronic
lighting type (i.e., an inverter or rapid-start fluorescent light).
Keep the distance between the receiver and the fluorescent
light as far as possible.
(2) Use suspension bolts to install the indoor unit. Check that
the place of installation withstands the weight of the indoor
unit. Secure the suspension bolts with proper beams if nec-
essary.
4. PREPARATIONS BEFORE INSTALLATION
(1) Check the positional relationship between the ceiling open-
ing hole and the suspension bolt of the unit. [unit: in. (mm)]
