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 fire protection system and devices in
operation.
WRENCH DESCRIPTION
The Sprinkler Wrench is a tool specifically 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 flow rate at the sprinkler. Check for the
proper model, style, orifice 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
Cover Plate - To install the conceal cover plate, align it
with the sprinkler and slowly turn clockwise for the cover
plates and sprinkler to lock in. Make sure the cover plate is
securely locked in, fail to do so may cause the sprinkler to
malfunction.
INSTALLATION SEQUENCE
Step 1. The unit must be installed in the Pendent position
for the Concealed Sprinkler.
Step 2. Use only a non-hardening pipe joint compound or
tape seal. Apply only to the male
threads.
Step 3. Hand tighten the sprinkler into fitting.
Step 4. For Concealed Sprinklers, use a standard wrench.
Tighten the unit into the fitting. A lead-tight joint requires
only 7 to 14ft.-lbs(9.5 to 19.0Nm) of torque. A tangential
force of 14 to 28ft.-lbs(62.3 to124.5N) delivered through
a 6”(150mm) handle will deliver adequate torque. Once
torque level reach over 21ft.-lbs(28.6Nm) it may distort
the orifice 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 caps are used to protect its bulb and deflector.
Please have cap on at all times during transportation and
interior decorating.
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
suffice.
Inspection and maintenance of fire 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.
