Caution: Special care must be taken
when installing with a CPVC system
to ensure that no primer or cement
accumulates within the sprinkler.
Special care must be taken when
installing with a copper system.
Sprinklers must be installed only after
the inside of the sprinkler drop and
associated fittings have been wire
brushed to remove any flux.
Residual flux can cause corrosion
and in extreme cases can impair
proper sprinkler operation.
qualified inspection service. Length
of time between such inspections can
vary due to accessibility, ambient
atmosphere, water supply, and site
activity.
Do not attempt to reassemble or
otherwise reuse a sprinkler that has
operated. Replace any sprinkler
exhibiting corrosion or damage;
always use new sprinklers of the
same type and temperature rating as
replacements.
Because the discharge pattern is
critical to protection of life and
property, nothing should be hung or
attached to the sprinkler unit that
would disrupt the pattern. Such
obstructions must be removed. In the
event that construction has altered
the original configuration, additional
sprinklers may need to be installed to
maintain protection level.
Do not attempt to replace sprinklers
without first removing the fire protec-
tion system from service. Be certain
to secure permission from all
Authori-
ties Having Jurisdiction
, and notify all
personnel who may be affected
during system shutdown. A fire watch
during maintenance periods is a
recommended precaution.
To remove the system from service
mode, first refer to the system
operating guide and valve instruc-
tions. Drain water and relieve
pressure in the pipes. Remove the
existing unit and install the replace-
ment, using only the special sprinkler
wrench. Be certain to match model,
style, orifice, and temperature rating.
A fire protection system that has
been shut off after activation should
be returned to service immediately.
Inspect the entire system for damage
and replace or repair as necessary.
Sprinklers that did not operate but
were subjected to corrosive elements
of combustion or excessive tempera-
tures should be inspected, and
replaced if need be. The
Authority
Having Jurisdiction
will detail mini-
mum replacement requirements and
regulations.

Care &
Maintenance
Sprinklers must be handled care-
fully. They must not be transported

been dropped or visibly damaged.
Sprinklers must never be painted,
coated, plated, or altered in any other
way from manufactured condition or
they may not function properly. Any
sprinklers altered in such a manner
must be replaced.
