This hot water tempering valve is designed to be installed at or near the boiler or water heater. They are not
designedtocompensateforsystempressureuctuationsandshouldnotbeusedwhereASSEstandard1016,
1069 or 1070 devices are required. These valves should never be used to provide “anti-scald” or “anti-chill”
service.
The components of the system must be of materials with a construction capable of withstanding the high limit
output temperatures of the water heating source.
Need for Periodic Inspection and Yearly Maintenance:Periodicinspectionandyearlymaintenancebya
licensed contractor is required. Corrosive water conditions, temperatures over 200°F, unauthorized adjustments
or repair could render the valve ineffective for service intended. Regular checking and cleaning of the valve’s
internal components and check stops helps assure maximum life and proper product function. Frequency of
cleaning and inspection depends upon local water conditions.
