The HydroGuard ® Lead Free * water tempering and recirculation loop is an eco-
nomical way to provide a safe, balanced system for stand-alone master tempering
valves The system monitors return line temperature and automatically directs
water to the cold side of the tempering valve (if within set point) or to the hot water
source (below set point) This is accomplished with Powers exclusive automatic
balancing valve (ABV), featuring paraffin-based, advanced actuation technology

TO ENSURE THE ACCURATE AND RELIABLE
OPERATION OF THIS PRODUCT, IT IS ESSENTIAL TO:
• Properly size each valve based on the individual
application
• Properly design the recirculation system to minimize
pressure and temperature variations
• Conduct an annual maintenance program to ensure
proper operation of all critical components
THIS VALVE MUST BE USED IN CONJUNCTION WITH
TEMPERATURE ACTUATED POINT-OF-USE DEVICES
THAT COMPLY WITH ASSE 1016, 1069, OR 1070.
FAILURE TO COMPLY WITH PROPER INSTALLATION
INSTRUCTIONS COULD CONTRIBUTE TO VALVE
FAILURE, RESULTING IN IN JURY OR DEATH.
WARNING !
*The wetted surface of this product contacted by consumable water contains less than 0.25% of lead by weight.
Please read and retain these instructions.
WARNING !
Need for Periodic Inspection: Periodic inspection by a licensed contractor is
recommended Corrosive water conditions, temperatures over 200°F, unauthor-
ized adjustments or repair could render the valve ineffective for service intend-
ed Regular checking and cleaning of thermostat assembly helps to assure
maximum life and proper product function Frequency of cleaning depends
upon local water conditions
