EXCAVATING FOR SKIMMER
Refer to Fig. 1 - 3 for rough-sizing the hole for the skimmer. Be sure
the bottom of the hole is heavily compacted to prevent settling. It is
important to have the general pond layout finalized at this time with
an overall idea of the final desired water level. The pond water level
can be determined by using a string level at various locations in the
excavated pond. The desired water level should be located 4" below
the top edge of the protruding surface on the skimmer (Fig. 4). The
weir cover plate has two water-level marks on the front to indicate the
proper pond water level for optimum skimming.
It would be recommended to cut the hole in the side of the skimmer
for the plumbing of the pump discharge (Fig. 5).
IF USING A BOTTOM DRAIN, IT IS IMPORTANT TO ADDRESS
THE LAYOUT DURING THIS PHASE OF THE INSTALLATION.
OPTIONAL BOTTOM DRAIN KIT
Installation of a bottom drain kit transforms the skimmer into a
dual-flow pre-filter, allowing it to automatically draw dirty water from
the bottom of the pond in addition to skimming the water surface.
FOLLOW THE INSTRUCTIONS SUPPLIED SEPARATELY WITH
THE BOTTOM DRAIN KIT, LOCATING THE DRAIN IN THE DEEP-
EST PORTION OF YOUR POND.
INSTALLING AND BACKFILLING SKIMMER
Place the empty skimmer vault in the excavated hole and check for
clearance around the skimmer on all sides before backfilling.
1. Install the PVC pipe support rod(s). Model SK2.5 uses only one
suppport rod; install it on the larger set of protrusions nearest
the brush rod. Models SK5 and SK10 use two support rods, one
upper and one lower. The short rod is the lower support and the
longer rod is the upper support. These are designed to perma-
nently fit on the protrusions inside the skimmer.
2. Check to make sure the vault is level from side to side and front
to back.
3. Check to make sure the discharge port is accessible on the side
being used. The opposite side, not being used, can be covered
with soil. Do not backfill so high that the lid does not fit on top.
4. Check to make sure the desired water level of the pond matches up
with the mark on the weir cover plate (Fig. 4).

5. Backfill soil directly under the skimmer entrance. Try to compact
the soil so that it is nearly flush with the front face of the skimmer.
This should be done to provide a solid surface for the pond liner
so that it isn't forced into the excavated space.
6. Backfill with soil around all surfaces on the skimmer.
ATTACHING LINER AND WEIR
NOTE: By this time the skimmer should be backfilled and the liner
can be attached.
Allow about 12" of slack in the liner (below the skimmer) to minimize
strain. This reduces strain on the liner as the pond is being filled with
water, and could be advantageous if the liner requires being re-cut.
Before beginning this portion, familiarize yourself with the weir cover
plate (Fig. 6), which is used to install the liner. The front portion of the
weir is flat. The reverse side of the weir cover plate has a protruding
feature that will be used to locate the liner.
1. Pull approximately 6 - 8" of liner up and lay it over the top of the
skimmer.
2. Lay the weir cover plate over the liner, approximately 6" down from
the edge of the liner. From the front side of the weir cover plate,
make two diagonal cuts from corner to corner, stopping the cut
about 1/4" from the corner.
3. Lightly stretch the liner and slide it over the edge of the weir cover
plate. Pull the liner up until it is held in place against the back.
Make sure that the liner lays flat against the plate.
4. Cut away the excess liner on the back side of the weir cover
plate and install the plate (with installed liner) onto the front of
the skimmer. Check to make sure the plate fits flush to the skim-
mer weir opening.
5. Apply RTV silicone (included) onto the front face of the skimmer
(Fig. 7).
6. Install the weir cover plate (with installed liner) onto the face of
the skimmer. Apply pressure so that the silicone is evenly com-
pressed and distributed on the sealing surface
7. Using a sharp point, pierce through the liner into each of the four
corner holes in the weir cover plate.
8. Install a 1/4"-20 bolt with washer into each of the four corner
holes (where the liner was pierced through) and hand-tighten
them.
