WARNING
When installing the unit horizontally, be sure to tilt the unit in
•
the direction shown in Fig. 1-2. If the unit is tilted in any other
way, water can leak.
Ensure suffi cient space for the bottom of the product
•
(H dimensions) so that a downward slope of 1/100 can
be maintained for drain piping, as described for the intake
duct installation and in “
6. DRAIN PIPING WORK
”.
[ PRECAUTION ]
Install the indoor and outdoor units, power supply wiring
•
and connecting wires at least 3.5 ft. away from televi-
sions or radios in order to prevent image interference or
noise. (Depending on the radio waves, a distance of
3.3 ft. may not be suffi cient to eliminate the noise.)
If installing the wireless kit in a room with electronic
•
fl uorescent lighting (inverter or rapid start type), the
remote controller’s transmission distance may be short-
ened. Indoor units should be installed as far away from
fl uorescent lighting as possible.
DANGER
Do not install unit in an area where fl ammable materials are
•
present due to the risk of an explosion resulting in serious
injury or death.
WARNING
If the supporting structural members are not strong enough
•
to take the unit’s weight, the unit could fall out of place and
cause serious injury.
