Need for Periodic Inspection/Maintenance:
This product
must be tested periodically in compliance with local codes, but
at least once per year or more as service conditions warrant. If
installed on a fire suppression system, all mechanical checks,
such as alarms and backflow preventers, should be flow tested
and inspected in accordance with NFPA 13 and/or NFPA 25.
All products must be retested once maintenance has been
performed. Corrosive water conditions and/or unauthorized
adjustments or repair could render the product ineffective for
the service intended. Regular checking and cleaning of the
product’s internal components helps assure maximum life and
proper product function.
