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 war-
rant. 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

WARNING
!
This device 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 sprinkler system, all
mechanical checks, such as alarm checks and backflow
preventers, should be flow tested and inspected internally in
accordance with NFPA 13 and NFPA 25.
WARNING
!
Do not impede or prevent sleeve movement by installing riser
cradle clamps or other obstructive elements on or around the
sleeve. Sleeve movement is required to service the backflow.
NOTICE
For Australia and New Zealand, line strainers should be installed
between the upstream shutoff valve and the inlet of the backflow
preventer.
C400-OSY-FS
Series C400, C500, and LFC500 each include a flood sensor on the
relief valve to detect excessive discharge and trigger notification of
potential flood events.
NOTICE
An add-on connection kit is required to activate the flood sensor.
Without the connection kit, the 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.

  • Page 2 Installation Guidelines • Most field problems occur because dirt and debris are present in the system at the time of installation and becomes trapped in check #1. The system should be flushed before the back- flow valve is installed. If the system is not flushed until after the backflow valve is installed, remove both check modules from the valve and open the inlet shutoff to allow water to flow for a sufficient time to flush debris from the water line.
