Temperature Setting
The delivered temperature of the valve varies depending on the temperature of the supplied hot water. The
valve is factory set at a supplied temperature of 149°F under balanced pressures. Depending on your
preferred hot water temperature setting, it may be necessary to adjust the calibrations of the valve. The
limit override button is preset at 100°F and can be adjusted as described below.
1. Select 100°F on the control handle.
2. Without turning the handle, remove the handle by unscrewing the screw and pulling off (screw may
be concealed and/or fastened with set screws).
3. Use a thermometer to check the delivered temperature on one of the outlets.
4. Adjust water temperature to 100°F by hand turning the cartridge stem slowly left or right.
5. Ensure that the temperature limit stop-ring is installed with red dot at 12 o’clock position.
6. Install the handle back on the valve with the push button at the 12 o’clock position.

Removal and Maintenance of Cartridge(s) (see Diagram 6)
This thermostatic cartridge has screens to prevent dirt and unwanted particles from damaging the valve.
Clogged screens can cause reduced flow and inefficient temperature mixture by the valve. You can easily
clean the screens by following the instructions below.
1. Remove the trim by following the Trim Installation steps above in reverse.
2. Shut off the water inlets by tightening the two screws at the two check stop valves.
3. Unscrew Thermostatic Cartridge (2) with a 30mm socket wrench or other adjustable wrench in a
counter-clockwise direction and gently pull out.
4. Clean the screens and rinse with water. If necessary, soak in a 50/50 mix of white vinegar/ water or
a de-scaling agent until all dirt is dissolved. Grease the o-rings with a silicone based grease and wipe
the housing with a wet cloth before reassembling.
5. Reassemble the valve by reversing these instructions. Make sure the red dot on the temperature
limit stop ring and push button on the handle are both aligned in the 12 o’clock position.
NOTE: Temperature may need to be reset as per instructions above.
NOTE: To prevent the handle from accumulating mineral build up which can cause the handle to “lock
up,”the handle must be turned on an occasional basis.
