Installation
The Model ESFR-25 Pendent Sprin-
klers are to be installed in accordance
with the following instructions:
NOTE
Damage to the fusible Link Assembly
during installation can be avoided by
handling the sprinkler by the frame
arms only (i.e., do not apply pressure
to the fusible Link Assembly), and by
using
the
appropriate
sprinkler
wrench. Damaged sprinklers must be
replaced.
A leak tight 1 inch NPT sprinkler joint
should be obtained with a torque of 20
to 30 ft.lbs. (26,8 to 40,2 Nm). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Step 1.
The ESFR-25 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 pres-
sure to the Link Assembly, and handle
the ESFR-25 Sprinkler only by the
Frame arms.
Step 3.
Wrench tighten the ESFR-25
Sprinkler using only the W-Type 1
Sprinkler Wrench (Ref. Figure 2) and
by fully engaging (seating) the wrench
on the sprinkler wrench flats.
Step 4.
After installation, inspect the
Link Assembly of each ESFR-25
Sprinkler for damage. In particular,
verify that the Link Assembly and Hook
are positioned as illustrated in Figure
1, and that the Link Assembly has not
been bent, creased, or forced out of its
normal position in any way.
Damaged sprinklers must be replaced.
Care and
Maintenance
The Model ESFR-25 must be main-
tained and serviced in accordance
with the following instructions:
NOTE
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection systems must
be obtained from the proper authori-
ties and all personnel who may be
affected by this action must be notified.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
ture will exceed 100°F/38°C and they
must never be painted, plated, coated,
or otherwise altered after leaving the
factory. Modified or over-heated sprin-
klers 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
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative to
any questions.
It is recommended that automatic
spr inkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
