3. SELECTING INSTALLATION SITE
AND AIR FLOW DIRECTION
3-1 Select an installation site where the following
conditions are fulfilled and that meets 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 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 pos-
sible within the allowable limit.
(Refer to the installation manual for the outdoor unit.)
[CAUTION]
Only use the included parts or parts which match the speci-
fications when installing the unit.
