Mounting Front Panel Assembly
1.
Remove return grille from front panel.
2. Move the front panel to the unit casing.
3. Tighten 4 partially threaded screws to attach the front panel as shown in Figure B.14.1 and Figure B.14.2. The front panel
does not move upwards excessively because the screws are not fully threaded (see below Figure B.14.3). Therefore, the
height of false ceiling and installation height should be measured accurately to ensure there is no gap between the false
ceiling and the front panel.
4. Install the grille back to front panel.
