NOTE TO THE INSTALLER
Be sure to instruct customers how to properly operate the
unit (especially cleaning filters, operating different functions,
and adjusting the temperature) by having them carry out
operations themselves while looking at the manual.
3. SELECTING INSTALLATION SITE
(1) Select an installation site where the following condi-
tions are satisfied and that meets with your customer’s
approval.
• Where the floor is strong enough to bear the indoor unit
weight.
• Where the floor is not significantly inclined.
• Where nothing blocks the air passage.
• Where condensate can be properly drained.
• Where sufficient clearance for installation and mainte-
nance can be ensured.
• Where optimum air distribution can be ensured.
• Where there is no risk of flammable gas leakage.
• Where piping between indoor and outdoor units is possi-
ble within the allowable limit. (Refer to the installation
manual of the outdoor unit.)
CAUTION
• Install the indoor and outdoor units, power supply wiring
and connecting wires at least 3.5 ft. away from televisions
or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.5 ft. may
not be enough to eliminate the noise.)
