the Deflector does not move up and
down freely, replace the entire Sprin-
kler assembly. Do not attempt to mod-
ify or repair a damaged sprinkler.
Step 7.
When installing an Air and
Dust Seal, refer to Figure 5, otherwise
proceed to Step 8. To attach the Air and
Dust Seal, verify the angle of the out-
side edge of the seal is oriented ac-
cording to Figure 5. 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.
NOTE
The Air and Dust Seal is only to be
installed on the periphery of the Re-
tainer.
Step 8.
Screw on the Cover Plate/Re-
tainer Assembly until the Retainer -
Figure 2 (or Air and Dust Seal - Figure
5) contacts 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/Re-
tainer Assembly cannot be engaged
sufficiently to contact the ceiling, the
Sprinkler Fitting must be repositioned.
Care and
Maintenance
The Series RFII must be maintained
and serviced in accordance with the
following instructions:
NOTES
Absence of the Cover Plate Assembly
may delay sprinkler operation in a fire
situation.
When properly installed, there is a
nominal 3/32 inch (2,4 mm) air gap
between the lip of the Cover Plate and
the ceiling, as shown in Figure 2. This
