levels of torque may distort the sprinkler inlet with conse-
quent leakage or impairment of the sprinkler.
The O-ring seal for pendent sprinklers must be installed
to prevent possible dripping of spray onto the fusible link,
due to clearance between the shield mounting hole and
the threaded end of the sprinkler.
1. Upright sprinklers must be installed only in the upright
position and pendent sprinklers must be installed only in
the pendent position. The centerline of the sprinkler
must be vertical.
2. Upright sprinklers are shipped preassembled, and pen-
dent sprinklers are to be field assembled. Refer to Fig-
ure 1 or 2, as applicable, for proper orientation of parts
for the pendent sprinkler. The speednut is installed by ro-
tating it clockwise over the sprinkler pipe threads, and
the O-ring is rolled over the sprinkler pipe threads.
When properly installed, the O-ring and speednut will be
slightly compressed, thereby firmly holding the shield in
its proper position.
3. With pipe thread sealant applied to the pipe threads,
hand tighten the sprinkler into the sprinkler fitting.
Wrench tighten the Sprinkler using only the W-Type 11
Sprinkler Wrench (Ref. Figure 3). The wrench recess of
the W-Type 11 is to be applied to the sprinkler wrench-
ing area (Ref. Figure 1 or 2, as applicable).
CARE AND MAINTENANCE
The 5.6 and 8.0 K-Factor, SuperNova S120 Sprinklers
must be maintained and serviced in accordance with the
following instructions:
NOTE
Before closing a fire protection system main control valve
for maintenance work on the fire protection system which
it controls, permission to shut down the affected fire pro-
tection systems must be obtained from the proper authori-
ties and all personnel who may be affected by this action
must be notified.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered after leaving the factory. Modified or over-heated
sprinklers must be replaced.
Care must be exercised to avoid damage - before, dur-
ing, and after installation. Sprinklers damaged by drop-
ping, striking, wrench twist/slippage, or the like, must be
replaced.
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 appli-
cable standards of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the standards of any
other authorities having jurisdiction. The installing contrac-
tor or sprinkler manufacturer should be contacted relative
to any questions.
It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.
