•
Pay careful attention when the pump is operated in manual mode.
•
The pump must be placed in a stable position inside a trap 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,
remove 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
automatically 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
overheating. See Troubleshooting.

6. 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-qualified party, in order
to prevent all risks.
