n Install VALVE at indicated height and depth. Make sure the “TOP” marking
on the PLASTER GUARD is up.
n Connect the hot and cold water supplies. Assemble all connecting pipes.

Reinstall it at the desired notch as indicated in the diagram to limit the
maximum mixed water temperature to 104 F or 112 F.
n For 100 F adjustment, turn the water supply on. Turn KNOB MOUNT until the
