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 recommended precaution.

To remove the system from service,

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
recommended 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 repaired and returned to
service immediately.  Inspect the

entire system for damage and replace
or repair as necessary.  Sprinklers
that did not operate but were sub-
jected 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.

Guarantee:  Central Sprinkler

Company  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
