Step 7.
When installing an Air and
Dust Seal, refer to Figure 4, otherwise
proceed to Step 8. To attach the Air
and Dust Seal, verify the angle of the
outside edge of the seal is oriented
according to Figure 4. Start the edge of
the Retainer in the grooved slot of the
Air and Dust Seal and continue around
the retainer until the entire Air and Dust
Seal is engaged.
Step 8.
Screw on the Cover Plate/
Retainer Assembly until the Retainer
Figure 2 (or Air and Dust Seal - Figure
4) makes contact with the ceiling. Do
not continue to screw on the Cover
Plate/ Retainer Assembly such that it
lifts a ceiling panel out of its normal
position. If the Cover Plate/Retainer
Assembly cannot be engaged with
the Support Cup or the Cover Plate/
Retainer Assembly cannot be engaged
sufficiently to contact the ceiling, the
Sprinkler Fitting must be repositioned.
