During operation

• Open the shut-off valve in the inlet and discharge line.
• The maximum inlet is less than the maximum output of the pumping station.
• Do not remove the chamber cover.
• Make sure that the pump chamber is sufficiently ventilated.
• If the outside temperature stays below 0 °C for a long time, there is a risk of frost in the pump chamber when the water exchange is not sufficient:
• Apply insulation measures above the chamber cover.
• Decommission the pump chamber.
