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. 6-17)
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. 6-18)
(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. 6-19)
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.
