It is advisable to have sprinkler
systems inspected regularly by a
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 re-assemble 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
discharge 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 the
protection level.
Do not attempt to replace sprinklers
without first removing the fire protection
system from service. Be certain to
secure permission from all
Authorities
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 instructions.
Drain water and relieve pressure in the
pipes. Remove the existing unit and
install the replacement, 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.

extreme cases can impair proper
sprinkler operation.
