What to look for if:
Flow of water is less than desired...
1. Checkstops or supply to N170 or LFN170 valve not fully open.
2. Clogged checkstop strainer screens.
3. Accumulation of lime deposits around plunger.
4. Low supply pressure.

3. Loss of either hot or cold
water supply pressure.
Discharge temperature varies...
1. Very large restriction in outlet flow.
2. Very large drop in inlet pressure.
3. Very large fluctuation of hot
water supply temperature.
4. Minimum flow requirement

WARRANTIES, EXPRESS OR IMPLIED. THE COMPANY HEREBY SPECIFICALLY DISCLAIMS ALL
OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
The remedy described in the first paragraph of this warranty shall constitute the sole and exclusive
remedy for breach of warranty, and the Company shall not be responsible for any incidental, special
or consequential damages, including without limitation, lost profits or the cost of repairing or replacing
other property which is damaged if this product does not work properly, other costs resulting from labor

shall be invalidated by any abuse, misuse, misapplication, improper installation or improper maintenance
or alteration of the product.
Some States do not allow limitations on how long an implied warranty lasts, and some States do not allow
the exclusion or limitation of incidental or consequential damages. Therefore the above limitations may
not apply to you. This Limited Warranty gives you specific legal rights, and you may have other rights
that vary from State to State. You should consult applicable state laws to determine your rights. SO

uada, o mantenimiento adecuado o alteración del producto.
Algunos Estados no permiten limitaciones en la duración de una garantía implícita y algunos Estados no permiten
la exclusión o limitación de daños accidentales o indirectos. Por lo tanto, es posible que las limitaciones anteriores
no sean aplicables en su caso. Esta garantía limitada le da derechos legales específicos; usted podría tener tam -
bién otros derechos que varían según el Estado. Usted debe consultar las leyes estatales aplicables para deter -
minar sus derechos. EN LA MEDIDA EN QUE SEA CONGRUENTE CON LAS LEYES ESTATALES APLICABLES,

WARNING !
Read this Manual BEFORE using this equipment.
Failure to read and follow all safety and use information can result in death,
serious personal injury, property damage, or damage to the equipment.
Keep this Manual for future reference.
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 temperatures of the water heating source.
WARNING !
WARNING !
Need for Periodic Inspection and Yearly Maintenance: Periodic inspec-
tion 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.
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 additional local requirements.
WARNING !
