 Installation notices
• When installing the indoor unit, be careful about the maintenance space.
• To set "3-direction", Air outlet shutter plate (option) must be installed, and the "outlet-direction"
need to be switched to "3-way" by the remote controller.
• In 3-way outlet mode, changing of ceiling height setting by function setting 20 is prohibited. (Ceil-
ing height setting [function setting 20] is allowed to be changed only in 4-way outlet mode.)
• Use the Insulation kit for high humidity (option), when the condition under the roof is over 80% in
humidity and over 30°C in temperature. Otherwise, there is a risk of condensation on the ceiling.
