When you are satisfied with the placement of the
FastFalls, remove the unit and install the liner and
underlayment, being careful not to disturb the
level base. Place the FastFalls on top of the liner
in its original position. Check the unit for
level to ensure that nothing has changed.
FastFalls Liner and Plumbing
Attachment
Hold the liner up against the flat panel on the back of the
FastFalls enclosure. Leave some excess slack in the liner below
the inlet. This will help alleviate any future strain on the liner connection. Make sure the
back surface of the FastFalls, and the back side of the liner is 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 Silicone Sealant in a
continuous, consistent bead
along the center of the threaded
inserts. Once completed, return
the liner to its dry-fit position.
Attach the supplied flange to
the FastFalls, starting with the
top screw first, working around
the flange. If needed, use an awl
or nail to pierce the liner before
inserting the screws. Do not fully
tighten any screws until all of
the screws have been installed.
Once completed, trim away the
liner on the inside of the flange
to expose the threaded inlet.
Tighten flange screws with a hand held screwdriver only. Over tightening the screws
could strip out the inserts or crack the liner flange. The screws need only to be snug
for the silicone to make a seal.
Apply silicone on the threads of the Male Thread Adaptor (MTA). Screw the MTA into the
inlet until tight. Use PVC Glue (not included) to glue the PVC flex hose into the MTA. Once
the FastFalls is sealed to the liner, level and positioned correctly, place a couple of large
stones on top of the FastFalls to ensure it does not move when backfilling.
