Ceiling height
The installable ceiling height of the air conditioner is within 4.2 m. If the height exceeds 4.2 m, distribution of the
air volume becomes poor.
If the ceiling height exceeds the standard value (Factory default) in the following table, hot air is difficult to arrive at
floor. Therefore it is necessary to set a high ceiling.
For setting method of the high ceiling, refer to Applicable control "Installing indoor unit on high ceiling" of this
manual.
