1) Select an installation site where the following con-
ditions are fulfilled and also that meets with your
customer's approval.
• If supporting structural members are not strong enough
to take the units weight, the unit could fall out of place
and cause serious injury.

can be ensured.

sible within the allowable limit (Refer to the installation
manual of the outdoor unit.)
• Keep the indoor and outdoor units, power cable and
transmission wiring, at least 1 m from TVs and radios,
to prevent distorted pictures and static.(Depending on
the type and source of the electrical waves, static may
be heard even when more than 1 m away.)
