ASSE 1017 model 5231 series high fl ow thermostatic mixing valves for
centralized systems are designed to be installed at the hot water heater
(point of distribution) and cannot be used for tempering water temperature
at fi xtures as a point-of-use valve. They are not designed to provide scald
protection and should not be used where ASSE 1070 devices are required.
Wherever a scald protection feature is required, ASSE 1070 model mixing
valves must be installed. For safety reasons, it is advisable to limit the
maximum mixed water temperature to 120°F. Series 5231 thermostatic
mixing valves can also be used for regulating the fl ow temperature in radiant
panel heating systems, to which it assures a constant and accurate control
with ease of installation.
