8. Tighten the provided screws in the bracket in the
cover panel immediately below each panel hanger.
See detail C in Figure 22. Adjust the cover panel by
turning slightly clockwise, if necessary, to make sure
that the panel is properly aligned with the cassette
base.
9. Continue to tighten the cover panel securing screws
until the insulation between the cover panel and the
cassette base has been compressed to approximately
¼”. The cover panel must form a seal with the ceiling
and the cassette base around the entire perimeter of
the unit. See Figure 23.
10. If it is necessary to adjust the cassette height after the
cover panel has been installed, access the leveling
nut through the removable access cover on each
corner. See Figure 24.
