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.)
•
In the case of the installation of a 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 hanging bolts to install the indoor unit. Check that the
place of installation withstands the weight of the indoor unit.
Secure the hanging bolts with proper beams if necessary.
