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 in.. or more as thermal insulation mate-
rial.
(1) Select an installation site where the following conditions are
fulfilled and that meets with your customer’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 the air passage.
• Where condensate can be properly drained.
• Where the false ceiling is not noticeably on an incline.
• 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 of the outdoor unit.)
