Precautions
Since the unit contains a drain pump and a float switch,
!
the body must be level.
If the body is installed in a tilted state, the float switch will
!
not function properly and thus will cause water leakage.
Installation of Ceiling Panel:
Install the ceiling panel following the installation manual
supplied with it.
Precautions
Before installing the ceiling panel, check that the body of
!
the unit has been installed correctly against the ceiling.
The ceiling panel and ceiling face must contact closely.
The ceiling panel and the contact side of the body must
!
contact closely. Any gap between them will cause air
leakage and thus generate condensation.
