Installation Instructions
When used on wet pipe systems, Reliable Model F3QR80
dry sprinklers may be installed in ductile or malleable cast iron
threaded tees, or CPVC tees and adapters upon verication
that the sprinkler inlet tting does not interfere with the interior
of the tting (see Figure 9).
When used on dry pipe systems, Reliable Model F3QR80 dry
pendent sprinklers MUST ONLY BE installed in the outlets of
ductile or malleable cast iron threaded tees on horizontal pipe
such that the inlet of the sprinkler protrudes above the bottom
level of the pipe.
When used on dry pipe systems, Reliable Model F3QR80 dry
sidewall sprinklers may be installed in ductile or malleable cast
iron threaded tees, or CPVC tees and adapters upon verica-
tion that the sprinkler inlet tting does not interfere with the inte-
rior of the tting (see Figure 9).
DO NOT install Reliable dry sprinklers into elbows or cou-
plings, welded outlets, mechanical tees, or gasket sealed
CPVC ttings.
Dry sprinklers connected to wet pipe systems must be in-
stalled as indicated in Figure 8 and as required by NFPA 13 with
the Exposed Minimum Barrel Length located in a heated area.
An orange protective clip is factory installed on the sprinkler
to protect the glass bulb thermal element from damage. The
clip should remain in place during installation of the sprinkler
and be removed when the sprinkler system is placed in service.
Use the following steps for installation:
1. Cut a hole in the wall or ceiling directly in-line with the
outlet of the tting. See the Installation Data table for the
recommended hole diameter based on the escutcheon
or cover plate option selected.
2. Apply pipe joint compound or PTFE tape to the male
threads of the sprinkler’s inlet tting.
3. Install the sprinkler in the tting using the installation
wrench specied in the Installation Data table. The
Model F3R wrenches are designed to be inserted into
the groves in the sprinkler’s wrench boss as shown in
Fig. 10. The Model XLO2 wrench is designed to t into
the cup and engage the wrench boss as shown in Fig.
11. Do NOT wrench any part of the sprinkler assembly
other than the wrench boss. When inserting or remov-
ing the wrench from the sprinkler, care should be tak-
en to prevent damage to the sprinkler. The sprinkler is
then tightened into the pipe tting to achieve a leak free
connection. The recommended minimum to maximum
installation torque is 22 - 30 lb-ft (30 – 40 N-m). Alter-
natively, where access to the outer tube of the sprinkler
is available, the Model F3QR80 Dry sprinkler may be in-
stalled using a pipe wrench. The pipe wrench shall only
be permitted to interface with the galvanized steel outer
tube portion of the sprinkler (Item #8 in Fig. 12). Do NOT
wrench any other portion of the sprinkler assembly. A
pipe wrench can install the sprinkler into the tting with a
large amount of torque; consideration should be given to
the need for future removal of the sprinkler because the
installation torque will have to be matched or exceeded
to remove the sprinkler. The recommended minimum
to maximum installation torque is 22 - 30 lb-ft (30 – 40
N-m).
4. Standard and Model HB escutcheons can be installed
by slipping the escutcheon over the can until the es-
cutcheon is seated against the ceiling or wall. The Mod-
el FP escutcheon is installed by pressing or threading
the escutcheon into the cup by hand; the escutcheon
can be tightened against the ceiling or wall by turning
the escutcheon in a clockwise direction and removed
by turning the escutcheon in a counter-clockwise direc-
tion. To install the Model CCP cover plate, rst remove
the protective clip. Install the Model CCP cover plate on
the sprinkler by pressing or threading the cover plate
into the cup by hand; the cover plate can be tightened
against the ceiling by turning the cover plate in a clock-
wise direction and removed by turning the cover plate in
a counter-clockwise direction.
5. Remove the orange protective clip when placing the
sprinkler system in service.
