WARNING
The pump must never pump against a closed shut-off valve! Otherwise there is a
danger of explosion in the pump or the piping system.
WARNING
Dewatering activities will have an impact on the surrounding area in which water
is being extracted from the ground.
Settling of the ground occurs during groundwater extraction. This can result in
grains of sand moving closer together, which will have an impact on the ground.
This can cause cracks in buildings and pipes.
It can also result in rotting of
wooden foundation piles if the groundwater is kept at a low level for an extended
period of time.
Before starting a dewatering system, make sure a sound dewatering plan has
been prepared and that the impact on the surrounding area is clear.
8.2 Stopping (type2)
1. Turn the switch on the control panel to off position (1).
2. When you suspect that the liquid is beginning to freeze, drain the pump while the medium is still
in the liquid state.
3. Before the pump is shut down, check whether this has an impact on the dewatering system.
4. Close the shut-off valve (if present).
5. Close the suction shut-off valve.
6. Switch off earth switch (1)
WARNING
When there is danger of freezing, drain the pump completely.
