Position of the pump
When the pipe or hose has been connected, place
the pump in its operating position.
Position the pump so that the pump inlet will not be
blocked or partly blocked by sludge, mud or similar
materials.
In the case of permanent installation, the pit must be
cleared of sludge, pebbles, etc. before the pump is
installed.

For permanent installation, we recommend that you
fit a union, a non-return valve and an isolating valve
in the outlet pipe.
