Setting the Thermostatic Mixing Valve

NOTICE

The thermostatic mixing valve controls the outlet hot water temperature deliv- ered to the faucets.

WARNING

POTENTIAL SCALD HAZARD The mixing valve must be installed on the PERFORMANCE PLUS. Removal of the mixing valve will create a potential scald hazard resulting in severe personal injury or death.

-Use a L-Key to remove the set screw securing the knob to the valve.

-Remove the knob and lock ring from the valve.

-Replace the knob and adjust the set temperature of the valve to the desired temperature.

NOTICE

To calibrate the outlet temperature, allow the water to run for approximately 2 minutes and measure the water with a thermometer. To adjust the valve setting, rotate the knob clockwise to decrease the water temperature or counter-clockwise to increase the water temperature.

-Once the desired temperature is achieved, remove the knob and refit the lock ring onto the valve aligning the ring indicator mark with the valve’s “Mix” marking.

-Locate the tab on the inner face of the knob into the retainer in the locking ring. Secure the knob with setscrew.

-Record the valve performance on the Installation Record included in this manual.

DANGER

For proper operation of the thermostatic mixing valve, the manual valve on the U- tube assembly MUST remain open to avoid a potential scald hazard.
