Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use information
can result in death, serious personal injury, property
damage, or damage to the equipment.
Keep this Manual for future reference.
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.
NOTICE
For Australia and New Zealand, line strainers should be installed
between the upstream shutoff valve and the inlet of the backflow
preventer.
Fittings such as end connectors intended to join alternative pipe
systems made from other materials (such as plastics) shall
also conform to the relevant dimensional and performance
requirements of the appropriate Australian, New Zealand, or joint
Australian–New Zealand Standard for the alternative pipe system.
LF860-OSY with Flood Sensor
Series LF860 and LF866 each include a sensor on the relief
valve to detect excessive discharge and trigger notification of a
potential flood event.
NOTICE
An add-on connection kit is required to activate the flood
sensor. Without the connection kit, the flood sensor is a passive
component that does not communicate with any other device.
(A retrofit sensor connection kit is also available for existing
installations. See "Add-on and Retrofit Sensor Connection Kits,"
for ordering details.)
NOTICE
Use of the flood sensor does not replace the need to comply with
all required instructions, codes, and regulations related to installation,
operation, and maintenance of this product, including the need to
provide proper drainage in the event of a discharge.
