locations.
Predrill the holes.
Secure the valve with the washers and screws. Do not overtighten!
IMPORTANT! When routing piping, the number marked at each valve outlet must correspond to the appropriate shower
fitting for preprogrammed or custom showering experiences to function properly. Refer to the Homeowners Guide for
more information.
Route the piping from the valve outlets to the appropriate shower fitting following the recommended pipe fitting sizes
listed.
Connect the hot and cold supply lines to the appropriate valve inlets. Hot is red and marked with "HOT," cold is blue
