WARNINGS
The SHIELD Sprinklers must be installed and maintained
in compliance with this document. Depressurize and drain
the piping system before attempting to install, remove,
or adjust any Sprinklers. Failure to do so may impair the
performance of these sprinklers. The owner is responsible
for maintaining the re protection system and devices in
operation.
WRENCH DESCRIPTION
The Sprinkler Wrench is a tool speci cally designed for
installing SHIELD Sprinklers. These special wrenches must
be used to provide the proper leverage when tightening the
sprinkler and to minimize slippage during installation. Any
other wrench may damage the sprinkler.
INSTALLATION
All SHIELD Sprinklers must be installed according to
NFPA 13 Standards. Deviations from these requirements
and standards or any alteration to the sprinkler itself will
void any warranty made by manufacturer. In addition,
installation must also meet local government provisions,
codes and standards as applicable.
The system piping must be properly sized to insure the
minimum required ow rate at the sprinkler. Check for the
proper model, style, ori ce size and temperature rating
prior to installation. Install sprinklers after the piping is in
place to avoid mechanical damage, replace any damaged
units. 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
task, remove the unit, apply new pipe joint compound or
tape, and reinstall.
ADDITIONAL
Recessed Sprinkler - To install the escutcheon plate,
align with it and push or thread over the sprinkler body
into the upper support piece, until the outer edge of the
escutcheon meets the mounting surface.
INSTALLATION SEQUENCE
Step 1. The unit must be installed in the upright position for
the Upright Sprinklers, and in the Pendent position for the
Pendent Sprinkler, Pendent Recessed Sprinkler.
Step 2. Use only a non-hardening pipe joint compouind or
tape seal. Apply only to the male threads.
Step 3. Hand tighten the sprinkler into tting.
Step 4. For Conventional Sprinklers, use a standard
wrench. Tighten the unit into the tting. A lead-tight joint
requires only 7 to 14ft.-lbs (9.5 to 19.0Nm) of torque. A
tangential force of 14 to28ft.-lbs (62.3 to 124.5N) delivered
through a 6”(150mm) handle will deliver adequate torque.
Once torque level reach over 21ft.-lbs (28.6Nm) it may
distort the ori ce seal, resulting in leakage. For exposed
piping systems, the sprinkler should be oriented so the
frame arms are parallel with the branch line pipe.
CAUTION
Do not over-tighten or under-tighten the sprinkler to
compensate for inaccurate escutcheon plate adjustment.
Protection clips are used to protect its bulb. Please have
clip on at all times during transportation.
MAINTENANCE
Sprinklers must never be altered after manufacture. Any
alteration such as painting and coating will directly harm
the sprinkler and cause malfunctions. Sprinkler in contact
with corrosive products should be replaced if they cannot
be cleaned completely.
Visual inspections are recommended after installation.
After installation, a close-up inspection annually will
suf ce.
Inspection and maintenance of re protection system is
the responsibility of the owner. It is recommended that
automatic sprinkler system be inspected and tested
according to local and/or national regulations.
