Watts N170 CSUT - Manual

Series N170
Hot Water Master Tempering Valves
Watts Series N170 hot water master tempering valves are
especially designed for use on larger hot water supply systems
for mixing hot and cold water for a variety of applications to
extend the hot water supply. This series uses paraffin-based
thermostat to sense and adjust outlet temperature.

Watts Hot Water Master Tempering Valves cannot be used for
tempering water temperature at fixtures. Severe bodily injury (i.e.,
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 MMV, USG, and L111 valves should be used at fixtures to
prevent possible injury.
The Watts Hot Water Tempering Valves are designed to be installed at
or near the boiler or water heater. 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” service.
