Watts reserves the right to change or modify product design, construction, specifications, or materials with-out prior notice and without incurring any obligation to make such changes and modifications on Watts products previously or subsequently with governing authorities for local installation requirementsThe information contained herein is not intended to replace the full product installation and safety information available or the experience of a trained product installer.

4 You are required to thoroughly read all installation instructions and product safety information before begin-ning the installation of this Hot Water Master Tempering Valves cannot be used for tempering Water temperature at fixtures. Severe bodily injury ( , scalding or chilling) and/or death may result depending upon system Water pressure changes and/or supply Water temperature changes. ASSE standard 1016, 1069 or 1070 listed devices such as Watts Series LFMMV, LFUSG, or LFL111 valves should be used at fixtures to prevent possible Watts Hot Water Tempering Valves are designed to be installed at or near the boiler or Water heater.

5 They are not designed to compensate for system pressure fluctuations and should not be used where ASSE standard 1016, 1069 or 1070 devices are required. These Watts valves should never be used to provide anti-scald or anti-chill ! * The wetted surface of this product contacted by consumable Water contains less than of lead by weight. ** With Equal Pressure** Low Limit cannot be less than the cold Water temperature. For best operation, hot Water should be at least 5 F (3 C) above desired set Capacity at 50-50 mixed Less CheckstopsPressure Drop Across ValveModelInlet / Outlet (NPT)Min.
