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.
• Check that all four vanes move. If two or four vanes do not move, refer to 5.3. and
check the connections.
• For 3D i-See sensor corner panel, check the rotating movement. If the 3D i-See
sensor does not rotate, review the procedure in "5.3. Installing the grille".
