alignment slot, as shown in Figure 4.
Engage by inserting the sprinkler into
the wrench cavity, fully seating the
wrench shoulder against the sprinkler
wrenching flange. Hand tighten the
sprinkler into the sprinkler fitting.
Step 3.
Once hand tight, attach ½ in.
(12,7 mm) drive to the sprinkler wrench,
as shown in Figure 4. Wrench-tighten
to ensure proper seal and alignment,
taking care to ensure the Deflector
Guide Pins do not come in contact with
any foreign body or surface.
Step 4.
After the wall has been com-
pleted with the nominal 2-5/8 in.
(66,7 mm) diameter clearance hole and
in preparation for installing the Cover
Plate Assembly, remove and discard
the Protective Cap. If the sprinkler has
been damaged in any way including
accidental over spray from finishing the
wall, replace the entire sprinkler.
NOTICE
The sprinkler must be installed in the
neutral or negative plenum only.
Step 5.
Push the Cover Plate Assem-
bly onto the Sprinkler, and as neces-
sary, make the final adjustment of the
Cover Plate with respect to the wall by
pushing the Cover Plate Assembly until
the retainer flange is flush against the
wall. If it becomes necessary to remove
the Cover Plate, it can be removed
merely by gently pulling the Cover
Plate Assembly away from the sprin-
kler body.
Note:
A Cover Plate Assembly not ade-
quately engaging the sprinkler body,
that is not securely attached, indicates
the sprinkler is positioned at a distance
from the mounting surface greater than
is described in Figure 3. A Cover Plate
Assembly fully engaged on the sprin-
kler body while the retainer flange is
not in contact with the wall indicates
the sprinkler is positioned at a distance
from the mounting surface lesser than
described in Figure 3. If either condi-
tion is encountered when attempting
to install the Cover Plate Assembly, the
sprinkler fitting must be repositioned.
