mate 1/16 inch (1,6 mm) diameter air
bubble should be present.
A leak tight 3/4 inch NPT sprinkler
joint should be obtained with a torque
of 10 to 20 ft.lbs. (13,4 to 26,8 Nm).
Higher levels of torque may distort the
sprinkler inlet with consequent leak-
age or impairment of the sprinkler.
The Model F898 Upright Large Drop
Sprinklers must only be installed in the
upright position. With pipe thread
sealant applied to the pipe threads,
wrench tighten the Model F898 by us-
ing only the W-Type 3 (End B) Sprin-
kler Wrench. The W-Type 3 is to be
applied to the sprinkler wrench flats
only.
CARE AND MAINTENANCE
The Model F898 Sprinklers must be
maintained and serviced in accord-
ance with the following instructions:
NOTE
Before closing a fire protection system
control valve for maintenance work
on the fire protection system which it
controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
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 sprinklers must be re-
placed. Sprinklers that have been ex-
posed to corrosive products of com-
bustion, but have not operated, should
be replaced if they cannot be com-
pletely cleaned by wiping the sprinkler
with a cloth or by brushing it with a soft
bristle brush.
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. Also, replace any sprinkler that
has a cracked bulb or that has lost
liquid from its bulb (ref. Installation
Section Note).
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any other
authorities having jurisdiction. The in-
stalling contractor or sprinkler manu-
facturer should be contacted relative to
any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service.
