WARNING !
Need for Periodic Inspection and Yearly Maintenance:
Periodic inspection and yearly maintenance by a licensed
contractor is required. Corrosive water conditions, and/or
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.
ATTENTION INSTALLER:
After installation, please leave this Instruction Sheet
for occupant’s information.
FAILURE TO COMPLY WITH PROPER INSTALLATION AND
MAINTENANCE INSTRUCTIONS COULD CONTRIBUTE TO THE
VALVE FAILURE.
This 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 should be used at fixtures to prevent possible injury.
These 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 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 tem-
peratures of the water heating source.
