Installation
NOTES
Damage to the fusible Link Assembly
during installation can be avoided by
handling the sprinkler by the frame
arms only and by using the appropriate
sprinkler wrench. Do not grip or apply
any force to the Fusible Link Assem-
bly. Damaged sprinklers must be re-
placed immediately.
A leak tight 3/4 inch NPT sprinkler joint
should be obtained with a torque of 10
to 20 ft.lbs. (13,4 to 26,8 Nm). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
The Model EC-17 Pendent Sprin-
klers must be installed in accordance
with the following instructions:
Step 1. The EC-17 Sprinkler must be
installed in the pendent position.
Step 2. With pipe thread sealant ap-
plied, hand tighten the sprinkler into
the sprinkler fitting. Do not apply any
force to the Link Assembly, and handle
the EC-17 Sprinkler only by the Frame
arms.
Step 3. Wrench tighten the EC-17
Sprinkler using only the W-Type 3
Sprinkler Wrench (Ref. Figure 3) and
by fully engaging (seating) the wrench
on the sprinkler wrench flats.
The Model EC-17 Recessed Pendent
Sprinklers must be installed in ac-
cordance with the following instruc-
tions.
Step A. After installing the Style 30
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. Wrench tighten the EC-17
Sprinkler using only the W-Type 24
Sprinkler Wrench (Ref. Figure 4) and
fully engaging (seating) the wrench on
the sprinkler wrench flats.
Step C. After the ceiling has been in-
stalled, slide the Style 30 Closure over
the Model EC-17 Sprinkler and push
the Closure over the Mounting Plate
until its flange comes in contact with
the ceiling.

painted, plated, coated, or otherwise
altered after leaving the factory. Modi-
fied or over-heated sprinklers must be
replaced.
Care must be exercised to avoid dam-
age - before, during, and after instal-
lation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage,
or the like, must be replaced.
The owner is responsible for the in-
spection, testing, and maintenance of
