2.3 Concrete Installation and

Modifications

For Sheer Descent, notch the bond beam 4-1/2 inches
(11.4 cm) deep and 1 inch (2.5 cm) longer than the
width of the unit. For FiberFalls, notch for unit length
plus 6 inches (15.2 cm) on the left to accommodate the
lens chamber and fiber cable, or 6 inches (15.2 cm) on
both sides for double-chambered units. FiberFall also
requires a 1 inch (2.5 cm) conduit stub-up in the beam
for the fiber cable(s). See Figure 4.
For vinyl and fiberglass pools, configure block to match
gunite beam installation.
After notching the beam (setting blocks), do the
following steps: (Refer to Figure 5.)
1. Determine waterfall installation level with bender
board.
2. Tack bender board at notch 1-3/8 inches (3.5 cm)
below bottom of coping.
3. Cement back of board.
