Step 5.
Replace the Protective Cap
by pushing it upwards until it bottoms
out against the Support Cup. (Refer
to Figure 4.) The Protective Cap helps
prevent damage to the Deflector and
Arms during ceiling installation and/or
finish. You can also use the Protective
Cap to locate the center of the clear-
ance hole by gently pushing the ceiling
material up against the center point of
the Protective Cap.
NOTICE
As long as the Protective Cap remains
in place, the system is considered “Out
of Service”.
Step 6.
After the ceiling has been
completed with the 2-1/2 inch (63,5
mm) diameter clearance hole and in
preparation for installing the Cover
Plate/Retainer Assembly, remove and
discard the Protective Cap. Verify that
the Deflector moves up and down
freely.
If the Sprinkler is damaged and the
Deflector does not move up and down
freely, replace the entire Sprinkler.
Do not attempt to modify 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
outside edge of the seal is oriented
according 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.
