Supplies recommended for installation

• Lockable shut-off on the outlet if tempered water is supplied to one or more emergency fixtures

• Lockable shut-off on the inlets/supplies

• (6) 3/8" wall anchors and fasteners for surface-mounted cabinet

• (4) 1/4" fasteners (and wall anchors, if necessary) for recess-mounted cabinet

• Unions on all connections to facilitate removal of valve

Tools required for temperature adjustment

• 5/32" Allen wrench

• Blade screwdriver

Install Optional Cabinet (If not installing cabinet, skip to Step 2)

1

Recessed Cabinet:

1. Rough-in wall opening 24-1/2" W x 28-1/2".

2. Insert the cabinet and secure to wall with four 1/4" fasteners
properly anchored (supplied by installer.)

3. Install two anchors and screws through the valve bracket in
back of the cabinet into a secure brace (supplied by installer) or
into wall. This will support the valve.

4. Install the valve nipples and one-half of the union ball valve
using pipe sealant or tefl on tape. Install the other half of the
union ball valve onto inlet and outlet pipe.

5. Insert the valve into the bracket in the cabinet (right side goes
in fi rst). Continue with the valve installation procedure.

6. Position the wall fl ange tight to the wall and caulk in place.

Surface-Mounted Cabinet:

1. Measure and mark the cabinet mounting hole locations
at the dimensions shown on next page. Install six 3/8" wall
anchors (supplied by installer).

2. Position the cabinet onto the wall and secure into place
with six 3/8" wall fasteners (supplied by installer).

3. Install the valve nipples and one-half of the union ball
valve using pipe sealant or tefl on tape. Then install the
other half of the union ball valve onto the inlet and outlet
piping.

This device must be checked for fi nal temperature and adjusted as
necessary. The standard preset factory temperature setting is 85°F
(29°C). [the range of the valve is 65°F – 95°F (18°C – 35°C)]. 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 fl ow. If the cold water is fl owing 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 fl ow has shut down. If hot water is shut down, reopen cold water supply. Test unit
weekly for proper function and desired set temperature.

DO NOT SKIP THIS STEP!!!

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

1. Turn off the recirculating pump and turn on the water supply at emergency fi xture (a water fl ow 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 fi xtures 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

Stop/Check Valve

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-connectio ns or leaking
stop/check valves

• Water heater output is at least 15° 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.

No hot water fl ow (cold

Limited water fl ow The inlet shut-off valve may be partially closed

Temperature fl uctuation
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 signifi cant 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 10 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 (S65-177).

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. 2-5/8").

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 (S65-178).

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 (S65-179).

Clean Stop and Check Valves as described above.

Enlarge the supply line size, reconfi gure the supply line or regulate
the supply usage.

Troubleshooting: Piston Disassembly and Cleaning

To prevent injuries, use proper protective equipment for
eyes and skin when using a propane torch.

Remove the valve’s top cap and pull out the
push rod and then the thermostat. You may use a

A

needle-nose pliers to remove the thermostat from
the valve body if desired.

Insert a 7/16" dia. rod into the valve and into the
piston overheat chamber. Mark the length of the

B

rod inside the valve. Push the rod until the piston
stops and mark the new length.

Top Cap

with Pushrod

Thermostat

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

C

D

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).

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 S65-180).
