EFX 125/S19-2300 Installation
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 1071. Operation of emergency
thermostatic mixing valves and fixtures must be tested weekly per ANSI/ISEA Z358.1. 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.
If shut-off valves are installed for maintenance purposes, provisions shall be made to prevent unauthorized
shut-off.
NOTICE
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 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.
Valve shall be accessible for testing, adjusting and maintenance in the installed position.
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.

DO NOT SKIP THIS STEP!!!
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.

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 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.

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.

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. See next page for piston disassembly and cleaning directions.
o-rings, contact your Bradley representative and ask for O-Ring Seal Kit (S65-
289).
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. 2-3/4" 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 (S65-178).
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 (S65-212).
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
push rod and then the thermostat. You may use a
needle-nose pliers to remove the thermostat from
A
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
Push Rod
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 S65-288).
