WARNING
Failure to comply with proper installation and maintenance instructions could contribute to the valve failure
resulting in severe bodily injury including scalding, chilling, and/or death depending upon system water
pressure changes and/or supply water temperature changes.
Use this Thermostatic Mixing Valve in accordance with ASSE standard 1070. This valve does not provide
protection from pipe freezing.
Output temperature of the valve must be checked and adjusted at initial installation and on a quarterly basis.
Make sure that all water supply lines have been flushed and then completely turned off before beginning
installation. Debris in supply lines can cause valves to malfunction.
NOTICE
Regular checking and cleaning of the valve’s internal components is necessary for maximum life and proper
product function. Periodic inspection and yearly maintenance by a licensed contractor is required. Corrosive
water conditions, and/or unauthorized adjustments or repairs could render the valve ineffective for its
intended service. Frequency of cleaning and inspection depends upon local water conditions.
IMPORTANT
Read this entire installation manual to ensure proper installation. When finished with the installation, file
this manual with the owner or maintenance department. Compliance and conformity to local codes and
ordinances is the responsibility of the installer.
Consult local building and plumbing codes prior to installation. Should these codes differ from the
information in the Manual, follow the local codes. Inquire with governing authorities for additional local
requirements.
Separate parts from packaging and make sure all parts are accounted for before discarding packaging
material. If any parts are missing, do not begin installation until you obtain the missing parts.
Product warranties may be found under “Products” on our web site at bradleycorp.com.

This valve is NOT factory preset. Upon installation, the temperature of this valve must be checked and adjusted
to ensure delivery of a safe water temperature. Water in excess of 110°F (43°C) may cause scalding.
Loosen cap screw about
1/4" (4-6 turns) and lift up

Shut the hot water inlet off by closing hot water inlet valve. While the hot water supply is turned off, check to make
sure the cold water flow is reduced. If the cold water is reduced properly, reopen the hot water supply.
Shut the cold water inlet off by closing the cold water inlet valve. While the cold water supply is off, check to make

Thermostatic Mixing Valve Troubleshooting
Before attempting to troubleshoot the valve or disassemble the components, check for the following conditions:
• If stop valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no crossconnections or leaking stop valves.
• Check the hot water heater output to make sure that it is at least 10° F above the set temperature.
Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen the valves after
inspection and repair is complete.
Problem Cause Solution
External leaks. Damaged cartridge or O-rings. Replace cartridge with part number 269-1927
Improper water temperature
or temperature fluctuation.
Hot water supply is not 10° above desired set
point.
Valve temperature is not properly set. Adjust the temperature as shown on page 3 step 2.
Increase hot water supply temperature
Limited water flow. Dirt and debris have built up in the valve or
strainer.
