Series EC-5 Recessed
Sidewall Sprinkler
The Series EC-5 Recessed Sidewall
Sprinklers must be installed in accor-
dance with the following instructions.
Step A.
Horizontal sidewall sprinklers
are to be installed with their center-
line perpendicular to the back wall and
parallel to the ceiling. The word “TOP”
on the deflector is to face towards the
ceiling.
Step B.
After installing the Style 50
sprinkler threads and with pipe thread
sealant applied to the pipe threads,
hand tighten the sprinkler into the
sprinkler fitting.
Step C.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
7 Recessed Sprinkler Wrench (Ref.
Figure 4). With reference to Figure
1, the W-Type 7 Recessed Sprinkler
Wrench is to be applied to the sprin-
kler wrench flats.
Step D.
After the wall has been
installed or the finish coat has been
applied, slide on the Style 50 Closure
over the Series EC-5 Sprinkler and
push the Closure over the Mounting
Plate until its flange comes in contact
with the wall.
Care and
Maintenance
The Series EC-5 Sprinklers must be
maintained 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 system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Absence of an escutcheon, which is
used to cover a clearance hole, may
delay the time to sprinkler operation in
a fire situation.
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
damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced. Also, replace any sprin-
kler that has a cracked bulb or that has
lost liquid from its bulb. (Ref. Installa-
tion Section).
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards of
the National Fire Protection Association
(e.g., NFPA 25), in addition to the stan-
dards of any other authorities having
jurisdiction. The installing contractor or
sprinkler manufacturer should be con-
tacted relative to any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national code.
