EUROMAC FLOW SP250 Manuel D'instructions page 13

If there is insufficient supervision of a pump that is functioning automatically, the pump may
break down despite the presence of the overheating safeguard. The user is always responsible
for supervising the device!
MAINTENANCE
Before you carry out checking or cleaning tasks on the pump you must switch it off and
remove the plug from the socket.
Your submersible pump is more or less maintenance-free. The only tasks you must carry out
are as follows:
 Carry out a regular visual inspection. Make sure the pump is not damaged. Check the
electrical cable, the plug, the float switch and the float cable for damage too. If you discover
damage, you must take the device to your supplier or an accredited professional. Never
attempt to carry out repairs yourself and never open the pump!
 Regularly check that the float switch is working effectively, particularly if you have set the
pump to work automatically.
 Regularly remove residues from the float with clean water.
 Regularly check (by putting your fingers into the suction openings) whether any dirt (fibres,
residues) has accumulated around the blade. Remove it if this is the case. If you cannot do
so, take the pump to your supplier or to an accredited professional to open the device and
remove the residue.
 If you regularly use the pump at different locations, you must rinse with clean water (inside
and out) after each use.
 Keep the base of the well (or the tile on which the pump is positioned) free from mud and
residue.
 Ensure that the pump does not freeze. Before winter sets in, run the pump dry and store it in
a frost-free location.
