Readjust the position of the sprinkler
fitting to suit.
Step 1.
The sprinkler must only be
installed with its centerline perpen-
dicular to the back wall and parallel to
the ceiling. The word “TOP” on the de-
flector is to face towards the ceiling.
Step 2.
Remove the Protective Cap.
Step 3.
With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.
Step 4.
Wrench tighten the sprinkler
using only the W-Type 7 Wrench (Ref.
Figure 3). The wrench recess of the
W-Type 7 Wrench is to be applied to
the Sprinkler Wrench Flats shown in
Figures 1 and 2.
Step 5.
Replace the Protective Cap
(Ref. Figure 4) by pushing it inwards
until it bottoms out against the Support
Cup. The Protective Cap helps prevent
damage to the Sprinkler to help protect
the sprinkler while the wall is being
plastered, wallpapered, or painted.
NOTE
As long as the Protective Cap remains
in place, the system is considered to
be “Out of Service”.
Step 6
. After the wall has been com-
pleted with the nominal 2-1/2 inch
(63,5 mm) diameter mounting 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 Sprin-
kler/Support Cup Assembly.
Step 7.
Push the Cover Plate/Re-
tainer Assembly into the Support Cup,
and as necessary, make the final ad-
justment of the Cover Plate with re-
spect to the wall by turning the Cover
Plate/Retainer Assembly clockwise
until its flange just comes in contact
with the wall.
If it becomes necessary to remove the
Cover Plate, it can be removed by un-
screwing in a counter-clockwise direc-
tion.
If the Cover Plate/Retainer Assembly
cannot be engaged with the Support
Cup or the Cover Plate/Retainer As-
sembly cannot be engaged sufficiently
to contact the wall, the Sprinkler Fitting
must be repositioned.
