TEMPERATURE LIMIT ADJUSTMENT

8

Remove Handle and Dial Cap as shown in 

STEP 7

.

The maximum hot water temperature setting adjustment 
(Temperature Limit Stop (TLS)) of the valve has been 
factory set at 110° F. Important- Check each valve 
installation with a thermometer to make sure the 
maximum hot water temperature is set to the 
recommended setting of 110° F maximum. To lower the 
limit of the maximum hot water temperature the valve 
delivers, adjust the valve’s temperature limit stop (TLS) 
plate.

1) Slip the retaining O-ring and the TLS plates towards 
the end of the spindle.

(2) With the water supplies on, rotate the valve spindle 
clockwise to the maximum desired hot water 
temperature. 

(3) Position the bottom TLS plate so it contacts the upper 
side of the bonnet post and therefore restricts the 
clockwise rotation of the spindle.

(4) The top TLS plate should be adjusted so that it comes 
in contact with the lower side of the bonnet post when 
the valve is rotated counter-clockwise to the “OFF” 
position.

(5) Slip the retaining O-ring back into the groove of the 
spindle to hold the TLS plates in place.
