The vanes of the unit can be set and locked in up or down orientations depending
upon the environment of use.

9.8. Check
• Make sure that there is no gap between the unit and the grille, or between the grille
and the surface of the ceiling. If there is any gap between the unit and the grille, or
between the grille and the surface of the ceiling, it may cause dew to collect.
• Make sure that the wires have been securely connected.
• For PLP-6BAE, PLP-6BAMDE, PLP-6BALME, check the rotating movement of
the i-see sensor. If the i-see sensor does not rotate, review the procedure in “9.6.
Installation of i-see sensor corner panel”.
