and adjusting the temperature) by having them carry out
operations themselves while looking at the manual.

SELECTING INSTALLATION SITE
Please attach additional thermal insulation material to the unit
body when it is believed that the relative humidity in the ceiling
exceeds 80%. Use glass wool, polyethylene foam, or similar
with a thickness of 10 mm or more as thermal insulation mate-
rial.
(1) Select an installation site where the following condi-
tions are fulfilled and that meets with your
customer’s approval.
• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate can be properly drained.
• In the upper space of the indoor unit where there is no
possible dripping of water from the refrigerant pipe, drain
pipe, water pipe, etc.
• If supporting structural members are not strong enough
to take the unit’s weight, the unit could fall out of place
and cause serious injury.
• Where the false ceiling is not noticeably on an incline.
• Where there is no risk of flammable gas leakage.
• Where sufficient clearance for maintenance and service
can be ensured.
• Where piping between indoor and outdoor units is possi-
ble within the allowable limit. (Refer to the installation
manual for the outdoor unit.)
• Any vents, light fixtures, or other appliances which may
disturb the airflow might cause the top side to become
dirty if located too nearby, so follow the figure below when
installing.
• Install the indoor and outdoor units, power supply wiring
and connecting wires at least 1 meter away from televi-
sions 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.)
