You are required to consult the local building and plumbing
codes prior to installation. If the information in this manual is
not consistent with local building or plumbing codes, the local
codes should be followed. Inquire with governing authorities for

WARNING !
WARNING !
Flush all pipes thoroughly before installation. Installation and
field adjustment are the responsibility of the installer.
WARNING !
Need for periodic inspection and Yearly Maintenance:
Periodic inspection and yearly maintenance by a licensed con-
tractor is required. Corrosive water conditions and/or unauthor-
ized 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.

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.
