Thermal Switch – Overheat Protection
The pump is equipped with an automatic thermal protection, which
prevents damage to the pump caused by overheating. If the pump
becomes too hot during operating, it will automatically switch off. Pull
the plug of the pump and allow the pump to cool down for approx.
30 minutes before operating again.
Running Dry
Absolutely avoid dry running of the pump!
Dry running is operating the pump without
water in the casing.
Vent Valve
The pump is equipped with a vent valve.
When inserting the pump into water the
pump will automatically ventilate.
Manual Operation
For manual operation you have to reposition the float switch at a higher
level or to keep the float switch up by hand. By doing this the water can
be pumped up completely. An automatic cutoff does not occur.
Do not operate the pump unsupervised during manual operation.
Disconnect the pump from power mains as soon as the water level falls
below 3.5 cm. Otherwise, the pump will run dry long and can be
damaged.
Maintenance, Cleaning, Storing and Transport
Unplug the power plug before undertaking any kind of maintenance
work or before cleaning.
The pump does not require maintenance apart from occasionally
cleaning the housing and the strainer.
