The owner is responsible for the proper
operating condition of all fire protection
devices and accessories. The NFPA
Standard 25 entitled,
“Inspection Testing
and Maintenance of Water-Based Fire
Protection Systems”, contains guidelines
and minimum maintenance requirements.
Furthermore, the local
Authority Having
Jurisdiction may have additional regula-
tions and requirements for maintenance,
testing, and inspection that must be
obeyed.
It is advisable to have sprinkler systems
inspected regularly by a qualified inspec-
tion service. Length of time between such
inspections can vary due to accessibility,
ambient atmosphere, water supply, and
site activity.
Do not attempt to reassemble or
otherwise reuse a sprinkler that has
operated. Replace any sprinkler exhibiting
corrosion or damage; always use new
sprinklers of the same type and tempera-
ture rating as replacements.
Do not attempt to replace sprinklers
without first removing the fire protection
system from service. Be certain to secure
permission from all
Authorities Having
Jurisdiction, and notify all personnel who
may be affected during system shutdown.
A fire watch during maintenance periods is
a recommended precaution.
To remove the system from service
mode, first refer to the system operating
guide and valve instruction. Drain the
water and relieve pressure in the pipes.
Remove the existing unit and install the
replacement, using only the special
sprinkler wrench. Be certain to match
model, style, orifice, and temperature
rating.
A fire protection system that has been
shut off after an activation should be
returned to service immediately. Inspect
the entire system for damage and
replace or repair as necessary. Sprin-
klers that did not operate but were
subjected to corrosive elements of
combustion or excessive temperatures
should be inspected, and replaced if
need be. The
Authority Having Jurisdic-
tion will detail minimum replacement
requirements and regulations.
Guarantee: Central Sprinkler Company
will repair and/or replace any products
found to be defective in material or
workmanship within a period of one year
from the date of shipment. Please refer
to the current Price List for further details
of the warranty.
Wet pipe systems must be protected
from freezing.
Upon completion of the installation, the
system must be tested per recognized
standards.
In the event of a thread leak, remove
the unit, apply new pipe joint compound
or tape, and reinstall.
Installation Sequence
Step 1. The unit must be installed in the
upright or pendent position.
Step 2. Use only a non-hardening pipe
joint compound or Teflon* tape. Apply
only to the male threads.
*Teflon is a trademark of the DuPont Corp.
Step 3. Hand tighten the sprinkler into
the fitting. Use a Central ELO Sprinkler
Wrench, to tighten the unit into the fitting.
A leak-tight joint requires only 7 to 14 ft.-
lbs. of torque; a tangential force of 14 to
28 lbs. delivered through a 6" handle will
deliver adequate torque. Torque levels
over 21 ft.-lbs. may distort the orifice
seal, resulting in leakage.
The sprinkler shall, per NFPA, be
oriented so the frame arms are parallel
with the branch line pipe.
