WARNING
!
FAILURE TO COMPLY WITH PROPER INSTALLATION
AND MAINTENANCE INSTRUCTIONS COULD
CONTRIBUTE TO THE VALVE FAILURE, RESULTING IN
INJURY AND/OR DEATH.
TO ENSURE THE ACCURATE AND RELIABLE OPERATION
OF THIS PRODUCT, IT IS ESSENTIAL TO:
• Properly design the system to minimize pressure and
temperature variations.
• This valve is not factory preset and can be adjusted
to deliver scalding temperatures. Check outlet tem-
perature to ensure it does not exceed 105°F (41°C).
Make sure temperature limit stop is properly re-set to
maximum 105°F (41°C) following valve maintenance or
repair. Tampering with limit stop in any way may result
in scalding temperature causing serious bodily harm
and/or death.
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 func-
tion. Frequency of cleaning and inspection depends upon
local water conditions.
WARNING
!
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
!
Flush all pipes thoroughly before installation. Installation and
field adjustment are the responsibility of the installer.

3. Route copper tubing or piping to fit valve dimensions.
4. For valves with PEX tailpieces see instructions on the
next page.
5. Remove tailpieces from the valve and make sure union nuts
are over the tubing/piping before connecting to the tailpiece.
6. Flush piping again, install valve using filter gasket on
hot and cold water inlets and fiber gasket on mixed
water outlet.
7. Turn on the cold and hot water. If any leaks are observed,
