9-1 Fill the System with Water
9-2 Turn On the Water Feature
Water should return to the Filter Tank before all the water is pumped out of the tank. If you run out of water this indicates you are short on containment. If you intend to turn the system off regularly, additional water storage should be added (T40SP Side-Pod).
9-3 Adjust the Fixed Skimmer as Needed
Adjust the Skimmer Height
Trim or lower the skimmer as needed to accommodate the pumping volume. You do not want the operating water level flowing over the top of the liner. The operating water level should be no closer than 2" from the top of the liner.
To Lower the Skimmer
The Fixed Skimmer is designed to be lowered in two ways. The Eccentric Coupling can be rotated to lower the operating water level (A), and for high flows the Fixed Skimmer opening can also be cut down (B). Either or both of these adjustments will lower the operating level of the vanishing pool.
To Raise the Skimmer
To raise the skimming depth, simply rotate the Eccentric Coupling.
9-4 Final Tasks
Finish placing rock around the Fixed Skimmer. The Fixed Skimmer can be hidden with natural elements or finished with a Stainless Steel Grate (use the riser kit if there will be leaves falling into the stream).
Things to check:
10-1 Install the Auto-fill, Pump Shut-off, and Accessories
If you are installing an Auto-Fill device and a Pump Shut-off, make sure the Auto-Fill is positioned above the Pump Shut-off level so water can be added before the pump switch turns the pump off. If the Auto-Fill is positioned too low it will never have a chance to
add water.
For installation instructions refer to instructions included in each kit.

Make sure the intake pipe has been backfilled. If you are installing an optional Auto-Fill or Pump Shut-Off, these should be positioned (see section 10) before adding water. Fill the system to the bottom of your overflow and turn the pump on.

Things to check:
- Make sure all stainless steel clamps have been tightened before backfilling.
- Make sure all water flowing down the stream is contained within the liner.
- Make sure there is at least 2" between the top of the liner and the operating level of the Vanishing Pool. If not, raise the liner accordingly, shorten the height of the skimmer, or reduce the pumping volume.
- Make sure that the system can be turned off and then turned back on without having to add water.
- Make sure that the terrain around the Filter Tank is graded so surface water does not collect around it.
