Installation
The TYCO Series TY-FRB, 5.6 K-factor,
Upright (TY313) and Pendent (TY323)
Sprinklers must be installed in accor-
dance with this section.
General Instructions
Do not install any bulb-type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm) for the 135°F (57°C) and 3/32
inch (2,4 mm) for the 286°F (141°C) tem-
perature ratings.
A leak-tight 1/2 inch NPT sprinkler
joint should be obtained by applying a
minimum to maximum torque of 7 to 14
ft.-lbs. (9,5 to 19,0 Nm). Higher levels
of torque can distort the sprinkler Inlet
with consequent leakage or impairment
of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in the Escutch-
eon Plate by under- or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Upright and Pendent Sprinklers
The Series TY-FRB Upright and
Pendent Sprinklers must be installed
in accordance with the following
instructions.
Step 1. Install Pendent sprinklers in the
pendent position. Install upright sprin-
klers in the upright position.
Step 2. With pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
6 Sprinkler Wrench (Figure 2). With ref-
erence to Figure 1, apply the W-Type 6
Sprinkler Wrench to the wrench flats.
Torque sprinklers 7 to 14 ft.-lbs. (9,5 to
19,0 Nm).
Recessed Pendent Sprinklers
The Series TY-FRB Recessed Pendent
Sprinklers must be installed in accor-
dance with the following instructions.
Step A. After installing the Style 15
or Style 20 Mounting Plate over the
sprinkler threads, and with pipe-thread
sealant applied to the pipe threads,
hand-tighten the sprinkler into the
sprinkler fitting.
Step B.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
7 Recessed Sprinkler Wrench (Figure
3). With reference to Figure 1, apply the
W-Type 7 Recessed Sprinkler Wrench
to the sprinkler wrench flats. Torque
sprinklers 7 to 14 ft.-lbs. (9,5 to 19,0
Nm).
Step C. After ceiling installation and
finishing, slide on the Style 15 or Style
20 Closure over the Series TY-FRB
Sprinkler and push the Closure over the
Mounting Plate until its flange comes in
contact with the ceiling.
