5. Operation
5.1 Automatic operation
When the plug of the electric cable is connected to the power supply, the pump
automatically switches on and off at the requested water level, see point 4.2.
5.2 Manual operation
By manual operation the pump is switched on when the plug of the electric cable is
connected to the power supply and the swimmer contact is in the top position.
6. Operation tips
The pump should not be idling and shall be switched off as soon as no more water
runs through it.
An inbuilt thermal cut-out switches the motor off when overheating. When the motor is
cooled off, it is automatically restarted (for further details see trouble shooting under
point 11).
Pull the plug not the cable when disconnecting the power.
Do not lift the pump in the electric cable and do not store the pump by hanging it in
the electric or swimmer cable. Tie a rope into the handle (2), when the pump is lifted
into a well or shaft
If the pump has been used for draining chlorine containing water from the swimming
pool or for pumping of other media which result in deposits, you shall rinse and clean
the pump with water.
Sand and other grinding material wears on the pump and reduces its capacity.
Avoid that the pump is idling for more than 10 min, this means that no water is
running through the pump.
By manual operation the pump can work with a water level of only 5 mm (see point 5).
The pump is equipped with a valve for automatic breathing of any air pockets which
are being formed when the water level in the pump has been below the level of the air
escape valve (4), When water again is flowing freely, a bit of water may force itself out
of the valve. If necessary disconnect the power supply for a moment and restart.
