3. Install the Rough Plumbing

IMPORTANT! Choose a fill spout which will provide a minimum 2" (5.1 cm) air gap above the basin rim
of the overflowing bath. In addition, if you plan to install a deck-mounted, hand-held shower, the diverter
vacuum breaker must maintain a minimum 1" (2.5 cm) air gap above the bathing well rim of the
overflowing bath.
Position the plumbing. Position the fill spout supply so the spout will reach beyond both the outer
rim and the bathing well rim. Water from the fill spout must be directed into the bathing well to
fill the overflowing bath. The overflowing bath should never be filled by directing water into the
overflow channel.
Cap the supplies, and check for leaks.

4. Prepare the Unit

Carefully lift the overflowing bath out of the carton.
Identify the box located inside the overflow channel. This box contains the metal suction screen, and
must be saved for use with this product.
Install the drain according to the drain manufacturer's instructions. Do not connect the trap at this
time.
Position a clean drop cloth or similar material in the bottom of the bath. Be careful not to scratch the
surface of the overflowing bath.
