S59-3130 Installation

IMPORTANT

WARNING! 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.

WARNING! Failure to comply with proper installation and maintenance instructions could contribute to
a 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.

This thermostatic mixing valve is designed to be installed at or near the boiler or water heater. It is not
designed to compensate for system pressure fluctuations and should not be used where ASSE standard
1016, 1069 or 1070 devices are required. These valves should never be used to provide "anti-scald" or "anti­chill" service. This valve does not provide protection from pipe freezing.

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.

Regular checking and cleaning of the valve's internal components and check stops 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 it's intended service. Frequency of cleaning and inspection depends upon local
water conditions.

Output temperature of the valve must be checked and adjusted at initial installation and on a quarterly basis.

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.

Product warranties may be found under “Products” on our web site at bradleycorp.com.

Flush the supply lines before
beginning installation.

When the check valves are in the
open (opera ting) position, the cover
screw for the stop/check stem will
be flush with the valve cap.

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 is significantly reduced. If the cold water is reduced 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. If hot water is shut down, reopen cold water supply. Test unit weekly for
proper function and desired set temperature.

Adjust Temperature with Water Running

Check the temperature when approximately
10 GPM water flow is reached (equivalent to
four standard showers).

This device must be checked for final temperature
and adjusted as necessary. The standard preset
factory temperature setting is 105°F (40°C). [the

range of the valve is 90°F – 120°F (32°C – 49°C)].

Consult proper medical and/or safety authorities
for the optimum temperature recommended for
your particular application.

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

1. Turn off the recirculating pump and turn on the water supply (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 #2 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 30 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 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.

Valve appearance may differ slightly.

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.

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.

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 (S65-215).

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. 2-25/35" to 3-1/4").

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 (S65-194).

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-

212).

Clean Stop and Check Valves as described above.

Enlarge the supply line size, reconfigure the supply line or
regulate the supply usage.

Troubleshooting: Piston Disassembly and Cleaning

WARNING! 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
thermostat and push rod. You may use a needle-

A

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
rod inside the valve. Push the rod until the piston

B

stops and mark the new length.

If the rod travels less than 9/16", 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

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).
