D. When replacing existing sprinklers, the system must be removed from service. Refer to the appropriate system description and/
or valve instructions. Prior to removing the system from service, notify all Authorities Having Jurisdiction. Consideration should
be given to employment of a fire patrol in the affected area.
E. Remove the system from service, drain all water, and relieve all pressure on the piping.
F. Using the special sprinkler wrench, remove the old sprinkler and install the new unit. Care must be taken to ensure that the re-
placement sprinkler is the proper model and style, with the correct orifice size, temperature rating, and response characteristics.
A fully stocked spare sprinkler cabinet should be provided for this purpose.
G. Place the system back in service and secure all valves. Check the replaced sprinklers and repair all leaks.
H. Sprinkler systems that have been subject to a fire must be returned to service as soon as possible. The entire system must
be inspected for damage and repaired or replaced as necessary. Sprinklers that have been exposed to corrosive products of
combustion, but have not operated, should be replaced. Refer to the Authorities Having Jurisdiction for minimum replacement
requirements.
