Skimmer Installation
This section describes the installation of the skimmer as part of a downwell system.
If the recovery well is much larger than the skimmer, we strongly suggest that a well
screen casing be used. This protects the skimmer from hanging up on the other hoses
in the well. A 2-inch skimmer will need a 2-inch casing an a 4-inch skimmer will need
a 4-inch casing. (PVC well casing can be used. Perforated stainless steel tubing can be
used if the PVC well casing will not fit)
STEP 1 - Remove the cable tie below the float. The cable tie prevents the float
from moving during shipping.
STEP 2 - Attach the Skimmer’s Quick-Connect to the inlet hose Quick-Connect
from any of the product pumps. ( See Figure 11)
STEP 3 -
Measure the thickness of the free product in the well
.
STEP 4 - Lower the skimmer and pump down the recovery well until the
midpoint of the skimmer’s guide tube(s) is located at the fluid level
in the well. This provides the skimmer with ample rise and fall
travel to accommodate reasonable fluctuation in the water table.
( See Figure 12)

,.
For a product thickness up to 6 inches, the midpoint of the guide
tube(s) can be positioned halfway into the product. For thicker
layers, the position can be calculated using the specific gravity of
the product.
i. Multiply the specific gravity of the product times the
product thickness.
ii Subtract the above results from the depth-to-water. Place
the midpoint of the guide tube at this point.
STEP 5 - Secure the support rope to the well cap eyebolt, if both are available .
