Remove the TEMPERATURE LIMIT STOP (4) (H shaped Black Plastic part).

Reinstall it at the desired notch as indicated in the diagram to limit the maximum mixed water temperature to 104 F or 112 F.

For 100 F adjustment, turn the water supply on. Turn KNOB MOUNT (3) until the spout temperature is 100 F. Check that arrow marking A on the KNOB MOUNT (3) still points upward after adjusting the thermostat to 100 F. If not, pull out the RED LOCKING DEVICE (5).

Remove KNOB MOUNT (3) without turning by sliding out as indicated by the arrow.
