Installation
The Series EC-5 Extended Coverage
Pendent Sprinklers must be installed
in accordance 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 bub-
ble should be present. The diameter of
the air bubble is approximately 1/16 in.
(1,6 mm).
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7
to 14 ft.-lbs. (9,5 to 19,0 Nm). Higher
levels of torque may distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in an Escutch-
eon Plate by under- or over-tightening
the Sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Step 1. The sprinkler must be in-
stalled with the deflector parallel to
the mounting surface. Pendent sprin-
klers must be installed in the pendent
position.
Step 2. After installing the Style 50
mounting plate (or other escutcheon,
as applicable) over the sprinkler pipe
threads and with pipe thread seal-
ant applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 3. Wrench tighten pendent sprin-
klers using only the W-Type 6 (End A)
Sprinkler Wrench. Wrench tighten the
recessed pendent sprinklers using
only the W-Type 7 Sprinkler Wrench.
The wrench recess of the applicable
sprinkler wrench (Ref. Figure 3 and 4)
is to be applied to the sprinkler wrench
flats (Ref. Figure 1).
Care and
Maintenance
The Series EC-5 Extended Coverage
Pendent Sprinklers must be main-
tained and serviced in accordance
with this section.
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 au-
thorities 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
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb. (Ref. Installa-
tion Section).
Frequent visual inspections are rec-
ommended to be initially performed
for corrosion resistant coated sprin-
klers, after the installation has been
completed, to verify the integrity of the
corrosion resistant coating. Thereaf-
ter, annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating as it may
be affected by the corrosive condi-
tions present.
The owner is responsible for the in-
spection, testing, and maintenance
of their fire protection system and de-
