No. Approval Representative Series LF825Y Reduced Pressure Zone Assemblies r y ; MI ��3/411 _211 FEBCO Series LF825Y Reduced Pressure Zone assemblies are used to protect against high hazard (toxic)fluids in water services to industrial plants, hospitals, morgues, mortuaries, and chemical plants.Applications also extend to irrigation systems, boiler feed, water lines, and other installations requiring maximum protection. The series features Lead Free*construction to comply with Lead Free*installation requirements. The series includes a flood sensor to detect excessive water discharges from the relief valve.The sensor is installed on the LF825Y-FS assembly exterior and does not alter assembly functions or certifications.The sensor relays a signal that triggers notification to facility personnel for corrective action, thus limiting flooding Operation and costly damage. In a flow condition the check valves are open with the pressure between the checks, called the zone, being maintained at least 5 psi lower than the inlet pressure and the relief valve is maintained closed. An add-on connection kit is required to activate the sensor. Should abnormal conditions arise under no flow or reversal of Without the connection kit,the sensor is a passive component flow, the differential relief valve opens and discharges to maintain that has no communication with any other device. (For more the zone at least 2 psi lower than the supply. information download RP/IS-F-825Y.) When normal flow resumes,the differential pressure in the zone Features resumes and the relief valve closes. • Ultimate mechanical protection of potable water, against hazards of cross-connection contamination EVITITM • Meets all specifications of AWWA,ASSE, and CSA Use of the flood sensor does not replace the need to comply with • Approved by the Foundation for Cross-Connection all required instructions, codes, and regulations related to instal* Control and Hydraulic Research at the University of lation, operation, and maintenance of this product, including the Southern California need to provide proper drainage in the event of a discharge. • Modular relief valve for ease of maintenance Watts°is not responsible for the failure of alerts due to • Simple service procedures connectivity or power issues. • All internal parts serviceable in line • Low head loss SUITTIMM • Spring loaded "Y"type check valves • Internal relief valve pressure sensing passages The information contained herein is not intended to replace the • Replaceable seat rings on all sizes full product installation and safety information available or the • End connection—NPT ANSI/ASME 131.20.1 experience of a trained product installer.You are required to thoroughly read all installation instructions and product safety • Sensor on relief valve for flood detection information before beginning the installation of this product. • Flood alerts feature activated with add-on sensor Inquire with governing authorities for local installation connection kit, compatible with BMS and cellular requirements. communication 'The wetted surface of this product contacted by consumable water contains less than 0.25%of lead by weight.
