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
during the recirculating process.
1. Turn off the recirculating pump and turn on the water supply at emergency fixture (a water flow rate of 10-15 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.

Problem Cause Solution
External leaks in the system Either the NPT joints or the o-rings have been damaged. 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 (S65-173) .
No hot water flow (cold water
flow only) The thermostat has failed and, subsequently, the safety shut-off has engaged. Inspect Thermostat:
1. Remove the top cap and pull out the push rod and thermostat.
2. Insert a 7/16" dia. rod into the thermostat bellows.
3. Mark the length of the thermostat bellows (at room temperature, with 10
lb. of force, the bellows length should be approx. 1-3/16"—1-1/2" ).
4. If the thermostat bellows 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 (S65-174).
Limited water flow The inlet shut-off valve may be partially closed 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. Clean Stop and check Valves:
Remove the stop and checks, clean the screen and seat and reassemble
the valve. Do not remove the seat. The components may be scraped with a
screwdriver 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 (S65-337).
Temperature fluctuation or
improper Temperature The stop and check sections of the valve do not move freely. Clean Stop and Check Valves as described above.
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
10 PSI. The supply line size may not be large enough to
supply both the valve and the other appliances.
Enlarge the supply line size, reconfigure the supply line or regulate the supply
usage.
Recirculation is not balanced. Review recirculation set up on page 6.
Piston does not move freely and must be cleaned. See next page for piston disassembly and cleaning directions.
Before attempting to troubleshoot the valve or disassemble
the components, check for the following:
• Stop/check valves are fully open (the slotted stem
must be flush with the stop/check cap) 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-connections or
leaking stop/check valves
• Water heater output is at least 15° F above the
set temperature.

Troubleshooting Thermostatic Mixing Valve
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.

If the rod travels less than1/2", the piston is not
moving freely within the liner and they must be
cleaned:
1. Remove the control section assembly, top
cap and thermostat.
2. Unthread the liner from the cap (it is glued
together; the o-rings must be removed and
heat should be applied to melt the glue and
loosen the liner).
3. Clean the piston and liner with any cleaner
suitable for brass and stainless steel (400-
grit sandpaper may be used to polish and
hone the piston and liner). 7/16"

B
Insert a 7/16"dia. rod into the valve and into the
piston overheat chamber. Mark the length of the
rod inside the valve. Push the rod until the piston
stops and mark the new length.
D
Push the mechanism up and down several
times to make sure the piston moves smoothly
and consistently. If it is not consistent, repeat
Procedure C until it moves freely, or replace.
Contact your Bradley representative and ask for
Piston/Liner Kit (part number S65-175).
ARemove the valve’s top cap and pull out the
push rod and then the thermostat. You may use a
needle-nose pliers to remove the thermostat from
the valve body if desired. Pushrod
