S19-2000, S19-2000EFX 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.

Install Optional Cabinet (If not installing cabinet, skip to Step 2)
If installing S19-2000EFX into Dropdown Eyewash Cabinet S19294JB,
S19294JBT, please see mounting instructions supplied with cabinet.
Recessed Cabinet:
1. Rough-in wall opening 11-1/2" W x 13" H.
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 teflon 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 first). Continue with the valve installation
procedure.
6. Position the wall flange 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 teflon tape.
Then install the other half of the union ball valve
onto the inlet and outlet piping.
4. Insert the valve into the bracket in the cabinet
(right side of the valve goes in first). Continue
with the valve installation procedure.
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
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).
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.

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.
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.

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

supply both the valve and the other appliances.
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.
