WARNING
!
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.
WARNING
!
The installation and maintenance of backflow assemblies should
be performed by a qualified, licensed technician. Failure to do
so may result in a malfunctioning assembly.
MasterSeries LF860-FS Large and LF866-FS are each equipped
with an integrated flood sensor that detects excessive relief
valve discharges and triggers notification of potential flood events.
An add-on sensor connection kit activates the alert system for use
with building management systems or cellular communication
networks. A retrofit sensor connection kit is available for existing
installations. See "Add-on and Retrofit Sensor Connection Kits,"
at the end of this document for qualifying series and valve sizes.
