FastFalls Installation

It is a good idea to install the bulkhead fitting and proper hose adaptor (not included) before setting the FastFalls. The SP1400 comes pre-drilled for a 1 ½” bulkhead fitting while the SP2500,3600,4800 come pre-drilled for a 2” bulkhead fitting. Refer to the bulkhead installation instructions on page 8 & 9 for more detail.

SETTING THE FAST-FALLS

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 pond’s 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

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, approx. 2” below the spillway. Once completed, return the liner to its dry-fit position and hold it in place with the provided spring clips.

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

Be extremely cautious when tightening the screws.You can use a cordless drill to start the screws; however, it is strongly recommended that you fi nish tightening them with a hand held screwdriver. Over tightening the screws could strip out the enclosure or crack the liner fl ange. The screws need only to be snug for the silicone to make a seal.
