remaining adjustment can be used to
compensate for the possible manufac-
turing variations in take-out of the fit-
ting, as well as in the make-in of the
sprinklers (as permitted by
ANSI
B1.20.1).
Step B.
After installing the F700
Mounting Plate over the sprinkler
threads, hand tighten the sprinkler into
the sprinkler fitting.
Step C.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
10 Recessed Sprinkler Wrench (Ref.
Figure D). With reference to Figure A,
the W-Type 10 Recessed Sprinkler
Wrench is to be applied to the sprinkler
wrenching flanges.
Step D.
After the ceiling has been in-
stalled or the finish coat has been ap-
plied, slide on the F700 Closure over
the Model F916 Sprinkler and push the
Closure over the Mounting Plate until
its flange comes in contact with the
ceiling.
CARE AND MAINTENANCE
Model F916 Sprinklers must be main-
tained 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 protection sys-
tem 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 which are found to be leak-
ing or exhibiting visible signs of corro-
sion must be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
tures will exceed 100°F/38°C and they
must never be painted, plated, coated,
or otherwise altered after leaving the
factory. Modified or over-heated sprin-
klers must be replaced.
Care must be exercised to avoid dam-
age to the sprinklers - before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed.
Frequent visual inspections are rec-
ommended to be initially performed for
wax and/or lead coated sprinklers, af-
ter the installation has been com-
pleted, to verify the long term potential
integrity of the sprinkler coatings.
Thereafter, annual inspections per
NFPA 25 should suffice; however, in-
stead of inspecting from the floor level,
a random sampling of close-up visual
inspections should be made, so as to
better determine the exact sprinkler
condition and the long term integrity of
the wax and/or lead coating, as it may
be affected by the corrosive conditions
present.
