Installation and Maintenance Instructions
Installation Instructions for Valve
CAUTION: If optional cabinet is to be used, the cabinet must be mounted before the valve
is installed. If using the S19-2000, please refer to the cabinet mounting
instructions on pages 4-5. If using the S19-2000EFX, please refer to the
mounting instructions supplied with the cabinet.
Note: Flush the supply lines before beginning
installation.
Note: When the stop/check valves are in the closed
position, the stem for the stop/check will be 1/4" above
the stem nut (see Figure 1). When the stop/check valves
are in the open position, the stem will extend out
approximately 1/2" (13 mm) from the stem nut.
1. Connect the hot and cold valve supply inlets to the
appropriate hot and cold supply piping.
2. Connect the mixed valve supply outlet from the
valve to the tempered supply piping.
3. Pressurize the thermostatic mixing valve and check
for pipe leaks.
4. Slowly open the outlet valve to fill the piping system.
5. Check the temperature when approx. 3-5 GPM
water flow is reached (equivalent to one eye wash
or face wash) and adjust if necessary (the range of
the valve is 65°F–95°F (18°C–35°C). To adjust the
temperature, follow the procedure below:
• remove the top screw to expose the set screw
• using a 5/32" hex-head Allen key, turn the set
screw counterclockwise to increase the
temperature or clockwise to decrease the
temperature.
Note: The standard preset factory temperature setting is
85°F (29°C). Consult proper medical and/or safety
authorities for the optimum temperature recommended
for your particular application.
6. Shut the hot water inlet off by closing either the hot
water check valve or inlet valve. While the hot
water supply is turned off, check to make sure the
cold water is flowing properly. If the cold water is
flowing properly, reopen the hot water supply.
7. Shut the cold water inlet off by closing either the
cold water check valve or inlet valve. While the
cold water supply is off, check to make sure that the
hot water flow has shut down.
8. Test the system weekly (turn on the water supply
and check for constant control of the desired set
temperature).
