7. INSTALLATION
1: Installing Model D-1 Guard on
Model M Sprinklers:
Model D-1 Sprinkler Guards can be
retrofitted onto sprinklers that have
already been installed on the system.
However, it is recommended to install
the guard onto the sprinkler prior to
installing the sprinkler on the system
and prior to applying any pipe-joint
compound or tape to the external
threads of the sprinkler. Consider or-
dering the guard factory installed on
the sprinkler used.
a: Loosen the screws in the brack-
ets at the base of the guard.
b: Spread and hold the two bracket
halves (at the base of the
guard) apart just enough to
place the guard over the deflec-
tor and wrench boss of the
sprinkler.
c: With the sprinkler inside the
guard, position the guard so the
two halves of the bracket grip the
sprinkler just below the wrench
boss but above the threads.
IMPORTANT! Orient the guard
so the screw openings in the
base of the guard are located at
the ends of the sprinkler
wrench boss (where the sprinkler
frame arms contact the wrench
boss). See Figure 1.
d: Thread both screws into the open-
ings provided in the opposite
bracket half and tighten to secure
the base of the guard to the sprin-
kler.
e: Apply a small amount of pipe joint
compound or tape to the external
threads only, taking care not to
allow a build-up of compound in
the sprinkler orifice.
f: Install the sprinkler on the piping
using the special sprinkler
wrench. DO NOT use the guard
to start or thread the sprinkler into
the fitting.
2: Installing Dry Sprinkler Guard:
Dry sprinklers must be installed on
the system prior to installing the
guard onto the Dry Sprinkler.
Note: When installing the Dry Sprin-
kler Guard on recessed Dry Pendent
or recessed Vertical Dry Sidewall
sprinklers the E-1 Escutcheon Cup
must be removed and the sprinkler
centered in a minimum 2-1/8" (54
mm) diameter hole prior to installa-
tion of the Dry Sprinkler Guard.
a: Remove the retaining ring from the
Dry Sprinkler Guard.
b: Spread and hold the two "C"
shaped halves of the bracket (at
the base of the guard) apart just
enough to place the guard over
the deflector and wrench boss of
the sprinkler.
c: With the sprinkler inside the
guard, position the guard so the
"C" shaped bracket halves of the
guard grip the sprinkler in the slot
provided just below the wrench
boss.
IMPORTANT! Orient the guard
so two of the four guard wires
align with the frame arms of the
sprinkler. See Figure 2
d: Push the retaining ring over the
guard toward the base of the
sprinkler until the ring snaps firmly
into the depression provided on
each of the four wire members of
the guard.
e: For recessed Dry Pendent or re-
cessed Vertical Dry Sidewall
Sprinklers, re-install the E-1 Es-
cutcheon Cup.
8. MAINTENANCE
For maintenance instructions, refer to
