3. 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 3/8” or more as thermal insulation material.
(1) Select an installation site where the following conditions
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 (including the back of the ceiling) 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.)
NOTE
• 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 sufficient enough to eliminate the noise.)
• Install this unit where the height of bottom panel is more
than 8.2 ft. so that the user cannot easily touch.
(length: in.)
NOTE
If installing the wireless kit in a room with electronic fluores-
cent lighting (inverter or rapid start type), the remote con-
troller’s transmission distance may be shortened. Indoor
units should be installed as far away from fluorescent light-
ing as possible.
(2) Use suspension bolts for installation. Check whether
the ceiling is strong enough to support the weight of
the unit or not. If there is a risk, reinforce the ceiling
before installing the unit.
(Installation pitch is marked on the paper pattern for instal-
lation. Refer to it to check for points requiring reinforcing.)
