Filter Shaft; Preparing The Filter Vessel - Steinbach Classic 250N Original Owner's Manual

Filter shaft

A filter shaft is required if the pool is partially or entirely installed in the
ground so you can place the pump of the filter system below the pool's
water level.
- Make sure that the filter shaft cannot be flooded and that ambient and rainwater can
drain away easily.
You can do so by installing a gravel layer at the bottom of the shaft. An optional
immersion pump with a float switch that is connected to a canal or drain additionally
protects your filter system from rising water inside the shaft.
- Ensure sufficient natural ventilation of the shaft to prevent condensation.
- Design the size of the filter shaft so that you can carry out work on the filter system.
