It is a good idea to install the bulkhead fitting and proper hose adaptor (not included) before setting the FilterFalls. A 1-1/2" threaded bulkhead has been provided in the installation kit.
It is always recommended that the FilterFalls be placed on undisturbed soil if possible. If the installation calls for the FilterFalls to be elevated above existing grade, it is critical to compact the area thoroughly. This will ensure that the FilterFalls will not settle out-of-level over time. The use of cinder blocks or bricks under the falls to raise it up will help reduce the chance of settling. The FilterFalls can be placed adjacent to the pond 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. FilterFalls should always be installed tilted slightly forward about 1/4". This will ensure that water never leaks out over the back of the enclosure. When you are finished positioning the unit, it is a good idea to weigh it down with a few rocks to keep it in place while you backfill and make your liner connection. Do not completely backfill the FilterFalls until all of your plumbing connections are made and the liner has been attached.
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 FilterFalls, 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 flange under the spillway, against the face of the enclosure, on top of the liner. The holes of the flange 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 flange to the filter. Be sure to seal the back of each screw with a dab of silicone on the inside of the enclosure.
