How do I set the adjustable rotational limit stop on my bath or shower?
Watch this how-to video or follow these steps:
Let the water run until both hot and cold water is fully mixed.
Rotate the handle fully counterclockwise to the hottest position.
Place a thermometer in a plastic tumbler, and hold the tumbler in the water stream.
If the water temperature is above what is allowed by your local plumbing code (110º F or 120º F), remove the handle on 1300/1400 series or temperature knob on 1700/1800 series, and rotate the rotational limit stop:
a. Counterclockwise if you have a Monitor® 1300 or 1400 series model (handle controls the temperature only, not the volume). For every tooth the rotational limit stop is rotated counterclockwise, the maximum water temperature will decrease approximately 6º F. NOTE: If water temperature is too cool, rotate the limit stop clockwise.
b. Clockwise if you have a Monitor 1700 or 1800 series model (handle controls volume; temperature knob controls temperature). For every tooth the rotational limit stop is rotated clockwise, the water temperature will decrease approximately 2º F. NOTE: If water temperature is too cool, rotate the limit stop counterclockwise.
For 1300/1400 series: Replace the handle. After verifying the water outlet temperature, secure the handle with the screw. Do not over tighten. For 1700/1800 series: After verifying water outlet temperature, snap temperature knob into place.
MAKE SURE COLD WATER FLOWS FROM THE VALVE FIRST. MAKE SURE WATER (AT THE HOTTEST FLOW) DOES NOT EXCEED THE TEMPERATURE ALLOWED (see steps 1-4 above).
Note: Consumer safety is our number one concern. If you do not have experience with plumbing repairs, we recommend that you contact a licensed plumber for tub/shower repairs.
