LF007-NRS-IOT
Series LF007 large-diameter backflow preventer is designed for
installation at referenced cross-connections to prevent the backflow
of polluted water into the potable water supply. Series LF007 Model IOT
includes factory-installed pressure sensors.
NOTICE
An add-on monitoring connection kit is required to collect psi
measurements from the integrated pressure sensors. Without the
connection kit, the pressure sensors are passive components
that do not communicate with any other device. For BMS only.
(The connection kit and pressure sensors are also available for
existing installations. For ordering details, see "Add-on Monitoring
Connection Kits."
NOTICE
Use of integrated pressure sensors and monitoring connection
kit with Model IOT does not remove the need to comply with all
required instructions, codes, and regulations related to installation,
operation, and maintenance of the backflow preventer.
Watts is not responsible for data transmission failures due to
connectivity issues, power outages, or improper installation.
