Installation
TYCO Model ESFR-17 Early Suppres-
sion, Fast Response 16.8K Pendent
Sprinklers must be installed in accor-
dance with this section.
General Instructions
Avoid damage to the fusible Link
Assembly during installation by using
only the Frame arms to handle the
sprinkler (i.e., do not apply pressure
to the fusible Link Assembly), and by
using the appropriate sprinkler wrench.
Failure to do so can lead to an unstable
link assembly and premature activation
of the sprinkler. Damaged sprinklers
must be replaced.
A leak-tight 3/4 inch NPT sprinkler
joint should be obtained by apply-
ing a minimum-to-maximum torque of
10 to 20 lbs.-ft. (13,4 to 26,8 Nm).
Higher levels of torque can distort the
sprinkler inlet with consequent leakage
or impairment of the sprinkler.
Note:
Install the Model ESFR-17
Pendent Sprinkler in the pendent posi-
tion (Ref. Figures 3 and 4).
Step 1.
With pipe-thread sealant
applied, hand-tighten the sprinkler into
the sprinkler fitting. Do not apply pres-
sure to the Link Assembly, and handle
the Model ESFR-17 Sprinkler only by
the Frame arms.
Step 2.
Wrench-tighten the Model
ESFR-17 Sprinkler using only the
W-Type 2 Sprinkler Wrench or the
W-Type 30 Sprinkler Wrench (Ref.
Figures 3 and 4), and by fully engag-
ing (seating) the wrench on the sprin-
kler wrench flats (Ref. Figures 1 and 2).
Step 3.
After installation, inspect the
Link Assembly of each Model ESFR-17
Sprinkler for damage. In particular,
verify that the Link Assembly and Hook
are positioned as illustrated in Figures
1 and 2, and that the Link Assembly
is not bent, creased, or forced out of
normal position in any way.
Replace
damaged sprinklers.
