3-6-2. Installing the Ceiling Panel
(1)Hang the temporary latches on the inside of the ceil- ing panel to the receptacle on the unit to temporarily attach the ceiling panel in place. (Fig.
The ceiling panel must be installed in the correct direction relative to the unit. Align the REF. PIPE and DRAIN marks on the ceiling panel corner with the correct positions on the unit.
(2)Align the panel installation holes and the unit screw holes. (Fig.
(3)Tighten the supplied special screws at the 4 panel installation locations so that the panel is attached tightly to the unit.
Check that the wiring connectors are not caught between the unit and the ceiling panel.
(4)Check that the panel is attached tightly to the ceiling. (Fig.
At this time, make sure that there are no gaps between the unit and the ceiling panel, or between the ceiling panel and the ceiling surface.
If there is a gap between the panel and the ceiling, leave the ceiling panel attached and make fine adjustments to the installation height of the unit to eliminate the gap with the ceiling.
