• You must have 20 mm or more space between the ceiling and the bottom of indoor unit. Otherwise, the noise from
the vibration of indoor unit may bother the user. When the ceiling is under construction, the hole for check-up
must be made to take service, clean and repair the unit.
• It is possible to install the unit at an height of between 2.2~2.5 m from the ground, if the unit has a duct with a
well defined lenght (300 mm or more), to avoid fan motor blower contact.
• If you install the cassette or duct type indoor unit on the ceiling with humidity over 80%, you must apply extra 10
mm of polyethylene foam or other insulation with similar material on the body of the indoor unit.
