During operation

• Open the gate valve in the inlet and discharge line!
• The maximum inflow is less than the maximum output of the unit.
• Do not remove the chamber cover!
• Ensure venting of the pump chamber!
• If the outside temperature remains below 0 °C for a prolonged period of time, there is a risk of frost in the pump chamber if the water exchange is insufficient:
• Provide insulation measures above the chamber cover.
• Decommission the pump chamber.
