4. 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

Please attach additional thermal insulation material to the unit body when it is believed that the relative humid-
ity in the ceiling exceeds 80%. Use glass wool, polyethylene foam, or similar with a thickness of 10 mm or
more as thermal insulation material.
(1) Select an installation site where the following conditions are fulfilled and that meets your cus-
tomer’s approval.
• 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.
• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate can be properly drained.
• Where the ceiling is strong enough to bear the indoor unit weight.
• Where the false ceiling is not noticeably on an incline.
• Where sufficient clearance for maintenance and service can be ensured.
• Where there is no risk of flammable gas leakage.
• Where piping between indoor and outdoor units is possible within the allowable limit.
(Refer to the installation manual for the outdoor unit.)
NOTE
• Leave 200 mm or more space where marked with the *, on sides where the air outlet is closed.
