Oasis FilterFalls Installation
BULKHEAD INSTALLATION (BF1600)
It is a good idea to install the bulkhead fitting and 1 ½” MTA (included) before
setting the BF1600. If 2” flexible PVC is being used for the supply line, replacing
the 1 ½” HA1550 bulkhead with an Atlantic 2” HA2000 bulkhead (not included)
is recommended.
Remove the retaining nut and plastic friction washer, leaving the rubber
gasket on the body of the bulkhead fitting. (Note: the retaining nut is reverse
threads. Turn clockwise to loosen).
From the inside of the FilterFalls, insert the threaded end of the bulkhead
into the hole on the back of the enclosure. This will sandwich the rubber gasket
between the flange of the bulkhead and the inside wall of the enclosure. Slip
the friction washer over the threaded end of the bulkhead on the outside of
the enclosure and install the retaining nut. Tighten the retaining nut by hand
and then finish off with ½ turn from a wrench. (Note: the retaining nut is reverse
threads. Turn counterclockwise to tighten).
SETTING THE BF1600
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

PLUMBING THE PS3900
The PS3900 Skimmer has pump discharge
step fittings molded into each side of the
skimmer enclosure. The step fittings are
labeled for 1 ½” or 2” PVC pipe and have
cut lines molded in for each size. Choose
the step fitting on the side of the skimmer
that will be best suited to exit based on this
installation. Using a PVC saw or standard hack
saw, remove the end of the step fitting (making sure to follow the molded cut
line) for the size pipe used for this water feature. Once completed, push one end
of the PVC supply line through the step fitting allowing approximately 10” of
pipe to enter the skimmer enclosure.
It is recommended that you install a TR215CV Triton Check Valve between the
pump and the supply line. This valve will prevent the FilterFalls from draining
when the pump is off, which keeps the beneficial bacteria alive and any debris
that the FilterFalls has collected from back flowing into your pond. Refer the
Triton Check Valve installation instructions on page 10 for further details.
A drill point is provided on both sides of your Oasis Skimmer to show the
proper location for the installation of an AF1000 Auto-fill valve (not included).
See the Auto-fill installation instructions on page 12 for more information.
There is a drill-point provided on the back of Oasis Skimmer to show the proper
location and elevation for the installation of an overflow (not included). See the
Overflow installation instructions on page 12 for more information.

Remove the spring clips and pull the liner away from the face of the enclosure.
Make sure that the front of the FilterFalls and the back side of the liner are clean
and free of debris. Apply a consistent bead of Atlantic fish-safe silicone to the
face of the FilterFalls along the center line of the threaded inserts (fig. 2).
