Information
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 wise precaution.
To remove the system from service
mode, first refer to the system
operating guide and valve instruction.
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 an activation
should be returned to service immedi-
ately. Inspect the entire system for
damage and replace or repair as
necessary. Sprinklers that did not
operate but were subjected to corro-
sive elements of combustion or
excessive temperatures should be
inspected, and replaced if need be.
The
Authority Having Jurisdiction will
detail minimum replacement require-
ments and regulations.
Guarantee: Central Sprinkler Com-
pany will repair and/or replace any
products found to be defective in
material or workmanship within a
period of one year from the date of
shipment. Please refer to the current
Price List for further details of the
warranty.
