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.
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.
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.
FEBCO Series 765 Pressure Vacuum Breakers are used to pro
tect against health hazard and non-health hazard backsiphonage
conditions in industrial plants, cooling towers laboratories, laundries,
swimming pools, and lawn sprinkler systems.
Series 765 includes a freeze sensor to indicate when temperature
nears the freezing point. The sensor relays a signal to building/irrigation
management systems when temperature crosses the preset threshold.
Freeze alerts are distributed according to BMS/IMS applications,
helping facility personnel take action to reduce or eliminate PVB
replacement or repair.

An add-on connection kit is required to activate the freeze sensor.
Without the connection kit, the sensor is a passive component that
has no communication with any other device. (The kit can also be
used to retrofit existing installations. For ordering details, see “Add-
on/Retrofit Sensor Connection Kit.”
Use of the freeze sensor and activation kit with FZ models does not
replace the need to comply with all required instructions, codes, and
regulations related to installation, operation, and maintenance of the
PVB assembly.
