Place the supplied flange under the spillway, against the face of the enclosure, on top of the
liner. The holes of the flange should be approximately 2” below the spillway so they line up
with the silicone bead. Using the stainless steel self piercing screws, attach the liner flange to the
FastFalls. Be sure to seal the back of each screw with a dab of silicone on the inside of the
enclosure (Figure 14).

SETTING THE FASTFALLS
It is always recommended that the FastFalls be placed on undisturbed soil if possible. If the
installation calls for the FastFalls to be elevated above existing grade, it is critical to compact the area
thoroughly. This will ensure that the FastFalls will not settle out of level over time.
The FastFalls can be placed adjacent to the basin edge to create a single waterfall, or pulled away
from the pond to create a streambed effect.
Once you have placed the unit, make sure it is level from side-to-side and check the level from
front-to-back. FastFalls should always be installed tilted slightly forward about ¼”. This will ensure that
water never leaks out over the back of the enclosure.
LINER ATTACHMENT
(SP1400, SP2500, SP3600, SP4800
)
Dry fit the liner. Hold the liner up against the flat panel of the FastFalls enclosure underneath
the spillway. Leave some excess slack in the liner below the spillway opening. This will help
alleviate any future strain on the liner connection. Make sure that the front surface of the
FastFalls, and the back side of the liner, are clean and free of debris. Once you are satisfied
with the position of the liner, lower it down and prepare to apply the silicone sealant.
Apply fish-safe silicone sealant in a consistent bead across the face of the FastFalls,
approximately 2” below the spillway. Once completed, return the liner to its dry-fit position
and hold it in place with the provided spring clips. (Figure 14).
Be extremely cautious when tightening the screws. You can use a cordless drill to start
the screws; however, it is strongly recommended that you finish tightening them with
a hand held screwdriver. Over tightening the screws could strip out the enclosure or
crack the liner flange. The screws need only to be snug for the silicone to make a seal.
