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.
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.
Valve shall be accessible for testing, adjusting and maintenance in the
installed position.
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.
Product warranties may be found under “Products” on our web site at
bradleycorp.com.

Tempered Water
(to Fixture)
Check for leaks by pressurizing
unit SLOWLY.
Check the temperature when approx. 3-5 gpm water
flow is reached (equivalent to one eye wash or face
wash) and adjust if necessary.
When the check stops are in the fully open
(opera ting) position, the stem will extend
approximately 1/2" (13mm) from the stem nut.
Adjust Temperature with Water Running
3
Check the temperature when approximately 3 – 5 gpm
water flow is reached (equivalent to one eye wash).
No single emergency fixture supplied by this device
shall have a minimum flow rate less then 1.5 gpm.
This device must be checked for final temperature and adjusted as
necessary. The standard preset factory temperature setting is 85°F
(29°C) [the range of the valve is 65°F–90°F (18°C–32°C)]. Insert
Allen Wrench through the hole in the cap and into the set screw
to adjust. Consult proper medical and/or safety authorities for the
optimum temperature recommended for your particular application.

Shut the hot water supply off by closing hot water inlet valve or supply check valve. While the hot water supply is turned off,
check to make sure the cold water continues to flow. If the cold water is flowing properly, reopen the hot water supply.
Shut the cold water supply off by closing the cold water inlet valve or supply check valve. While the cold water supply is off,
check to make sure that the hot water flow has shut down to less then 0.5 gpm. If hot water is shut down, fully reopen cold
water supply.
Test the system weekly (turn on the water supply and check for constant control of the desired set temperature).
DO NOT SKIP THIS STEP!!!

Optional Water Recirculation Setup

Recirculating the water in the system provides constant regulation of the water temperature. Flush the supply lines thoroughly
after completing installation. Close off all fixtures and label them as not available for use durin g the recirculating process.

Recirculating Pump
1. Turn off the recirculating pump and turn on the water supply at emergency fixture (a water flow rate of 3 – 5 gpm is required).
2. Let the water run through the system until a consistent temperature is obtained. If you do not obtain the required temperature,
refer to step #3 on previous page for temperature readjustment.
3. As soon as the water reaches the proper temperature, turn on the recirculating pump (make certain the proper system
temperature has been achieved before proceeding).
4. Check the water temperature at the return pump. If the temperature exceeds the appropriate level by 2°F, adjust the temperature
high-limit switch (this will turn off the pump). Wait until the return water temperature is 5°F below the appropriate level and adjust the
low-limit switch (this will turn the pump back on).
5. Open the balancing valve completely.
6. Turn off all fixtures and make sure there is no water running through the system (the cold inlet pipe should feel warm to the touch).
7. Let the system run for 30 minutes or longer without water. If, after thirty minutes, the water temperature increases, you may
readjust the temperature by slowly closing the balancing valve until the appropriate temperature is reached.

Troubleshooting Thermostatic Mixing Valve
Before attempting to troubleshoot the valve or
disassemble the components, check for the following:
• Stop/check valves are fully open (the slotted stem
extends approximately 1/2" from the stem nut) and
that all inlet and outlet shut-off valves are open.
• Hot and cold inlet pipes are connected properly,
and that there are no cross-connectio ns or leaking
stop/check valves.
• Water heater output is at least 20° 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.

Temperature fluctuation
or improper Temperature
Either the NPT joints or the o-rings have been
damaged.
The thermostat has failed and, subsequently, the
safety shut-off has engaged.
or there has been a significant decrease in water
pressure.
Dirt and debris have collected on the check
screen or seat, limiting the movement of the stop
and checks.
The stop and check sections of the valve do not
move freely.
Thermostat is slowly failing. Check Thermostat as described above, or replace.
Inlet supply line to the mixing valve is being
shared by other pieces of equipment that are
used only periodically, such as laundry appliances
or washdown stations. It may reduce the inlet
pressure to the mixing valve to less than 3 PSI.
The supply line size may not be large enough to
supply both the valve and the other appliances.
Recirculation is not balanced. Review recirculation set up on page 5.
Piston does not move freely and must be cleaned. See next page for piston disassembly and cleaning directions.
Replace the NPT joints and/or o-rings where necessary. For
replacement of o-rings, contact your Bradley representative and ask
for O-Ring Seal Kit (S65-170).
Inspect Thermostat:
1. Remove the top cap and thermostat.
2. Insert the 5/16" dia. push rod into the thermostat bellows.
3. Mark the length the push rod extends into the bellows (at room
temperature, with 10 lb. of force. the length should be approx.
15/16" – 1-3/16").
4. If the push rod length is not in the proper range, the thermostat
must be replaced (it cannot be repaired). Contact your Bradley
representative and ask for Thermostat Kit (S65-171).
Clean Stop and check Valves:
Remove the stop and checks, clean the seat and reassemble the
valve. Do not remove the seat. The components may be brushed
with a small wire brush to remove debris. A pair of tweezers works
well for pulling debris out from the seat. If the stop and checks need
to be replaced, contact your Bradley representative and ask for
Check/Stop Kit (S27-102-Rough Brass, or S27-292A-Chrome).
Clean Stop and Check Valves as described above.
Enlarge the supply line size, reconfigure the supply line or regulate
the supply usage.

and lift out parts with a needle-nose pliers.
Dissamble and clean the piston assembly parts
D
with any cleaner suitable for brass and stainless
steel. (if necessary, use a 400-grit sandpaper to
polish and hone the piston and liner.)
Re-assemble the piston assembly. Push the
mechanism up and down several times to make sure
the piston moves smoothly and consistently. If it is not
E
consistent, repeat Procedure D until it moves freely, or
replace. Contact your Bradley representative and ask
for Piston/Liner Kit (part number S65-172).
