at least once per year or more as service conditions warrant.
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 and external components helps assure maximum life and
proper product function.
WARNING
!
Freeze sensor solely provides alerts about a possible freeze event
and cannot prevent a freeze event from occurring. User action is
required to prevent freeze conditions from causing product and/
or property damage.
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.
LF007 with Freeze Sensor
Series 007 and LF007 small-diameter backflow preventers are
designed for installation at referenced cross-connections to prevent
the backflow of polluted water into the potable water supply. Both
series include a freezer sensor to signal building/irrigation management
systems when temperature hits the freeze thresholds.
NOTICE
An add-on connection kit is required to activate the freeze sensor.
Without the connection kit, the sensor is a passive component that
does not communicate with any other device. (The kit can also be used
to retrofit existing installations. For ordering details, see "Add-on Sensor
Connection Kit.") BMS/IMS only.
NOTICE
Use of freeze sensor 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 or the failure
of alerts due to connectivity issues, power outages, or improper
installation.
