Mobile application
In the case of an outdoor application always comply with the regulations acc. to DIN/VDE
0100 part 702. Make sure that the plug does not get wet.

able to switch it off in case of a breakdown. Clean the pump after operation (described in section 4).
Flat-pumping method (types STANDARD, S and SA only)
In manual operation the pump removes liquid down to a level of a few millimetres (see illustration next
page).
To procced remove the plug from the power supply. Place a suitable tool (e.g. screwdriver) into one of the
openings of the strainer and pull it off the pump casing (see illustration section 4).
The pump is now able to suck off the residual liquid in the vertical position.
A firm, flat surface is required for the flat-pumping method. Foils (e.g., pond under foils)
are not a suitable surface. Foils can be sucked into the pump and clog the opening.
Hazard caused by moving parts. After flat-pumping the strainer has to be remounted
immediately. In case of loss or damage it has to be replaced immediately.
