6. Install the Waterway

Insert the escutcheon into the opening.
If any of the leak shields makes contact with an elbow: Enlarge

the hole in the back of the leak shield to 1-1/4″ (32 mm).
Thread the adapter onto the nipple using the provided 11 mm bit,

11 mm or 7/16″ socket, extension and socket wrench. Use
masking tape to hold the bit in place, as the bit could fall off and
cause damage.

IMPORTANT! The escutcheon should sit loosely at this point. If it
is tight against the wall, use a longer pipe nipple.

Align the groove in the waterway with the double ribs on the
leak shield.

Press the waterway into place over the adapter. Secure the
waterway to the adapter with the screw provided.

Verify that the escutcheon does not turn or shift.
