• The pump must only be used when it is immersed in water. If the water runs out, the pump must be stopped
immediately by removing the plug from the power supply.
• Pay careful attention when the pump is operated in manual mode.
• The pump must be placed in a stable position inside a collection pit or in the lowest part of the place where
it is installed.
• The float must be able to move freely while the pump is in operation, so the recommended dimensions for
the trap are 40x40 cm.
• It is absolutely essential to prevent any risk of the pump freezing. In the event of freezing temperatures, remo
ve the pump from the liquid, empty it and keep it in a place where it cannot freeze.
Overload protection
The pump has a thermal overload safety device. In the event of any overheating of the motor, this device au-
tomatically switches off the pump. The cooling time is roughly 15 to 20 minutes, then the pump automatically
comes on again. If the overload cutout is tripped, it is essential to identify and deal with the cause of the overhe-
ating. See Troubleshooting.
5. TROUBLESHOOTING
Before taking any troubleshooting action, disconnect the pump from the power supply (i.e. remove
the plug from the socket).
If there is any damage to the power cord or pump, any necessary repairs or replacements must be
handled by the manufacturer or his authorized customer support service, or by an equally qualifi
ed party, in order to prevent all risks.
Fault
Possible causes
Solutions
The motor does not start or
makes no noise.
A. Make sure the motor is powered.
B. The pump is not enabled by the float.
B. - Make sure the float can move
freely.
- Increase the depth of the trap.
The pump delivers no water.
A. The suction grid or piping are clogged.
B. The impeller is worn or stuck.
C. The required head is too high for the
characteristics of the pump.
A. Remove the obstruction.
B. Replace the impeller or remo-
ve the obstruction.
The pump does not stop.
A. The pump is not disabled by the float.
A. Make sure the float can move
freely.
The flow rate is too low.
A Make sure the suction grid is not partial-
ly clogged.
B. Make sure the impeller or delivery pipe
are not partially clogged or fouled.
A. Remove any obstructions.
B. Remove any obstructions.
The pump stops after a
brief period of operation.
A. The thermal cutout stops the pump.
A. - Make sure the fluid being
pumped is not too dense, causing
the motor to overheat.
- Make sure the temperature of
the water is not too high.
- Make sure there is no solid
body obstructing the impeller.
