V. OPERATION
5.1- Intended use
1. Submersible pumps are intended for domestic use around the house and garden.
They should be used only for drying out flooded premises or for pumping water out of wells or
cellars.
2. This pump is designed to suck up clear or slightly dirty water with particles in suspension that are
less than [see table 1] in diameter.
3. The pump is fully submersible: the immersion depth must not exceed [see table II - technical
characteristics].
4. The pump should not be used for sucking up liquids or materials that are corrosive, combustible
or explosive; fats, oils, heavily dirty water and waste water from toilet, food liquids...
5. The temperature of liquids sucked up should not exceed 35°C.
6. Any other use, other than that described in the instructions, is likely to damage the pump and to
put the user in serious danger.

5.2- Operation

5.2.1- In automatic functioning mode,
Connect pump to mains power.
Lower the float switch (4) to "auto" position (see Fig.4).
The pump will start and stop as soon as the float switch reaches the pre-set heights (see 4.3)
5.2.2- In manual functioning mode
Raise the float switch (4) to "MAN" position (see Fig.4).
To operate the pump, connect plug to mains socket.
Note: in this case, the minimum pumping water height may be reduced.
5.2.3- Warning!
Never operate the pump without water (dry running).
The pump is not designed for continuous operation! (e.g. continuous water circulating operation).
The submersible pump must be immersed before switching on.
Place pump into water, then let it purge the air (air bubbles) then only you can connect it.
In automatic functioning, the filling-up time before float switch operates is enough to purge the air.
Check the water level frequently while in operation, to see whether it is lowering and the pump shall
not be out of water while running.
5.3- Operating hints
1. if discharge stops although the pump continues to function, switch it off immediately.
Unplug the pump from the mains and check to see what is causing the problem.
Never attempt to remove the turbine when the pump is still connected to the power supply.
2. The pump is fitted with a motor protected by a thermal safety with auto reset. In the
event of overheating, the motor stops automatically. As soon as the temperature returns to
normal, the motor restarts.
Never place hands anywhere near the turbine during this phase. If remedial action is necessary,
always unplug the pump from the power supply first.
3. The pump is also fitted with an automatic bleed device to evacuate any air that might have got into
the suction circuit.
When the water level drops below the vent located in the middle of the pump body, water is
evacuated by this hole so as to automatically bleed the circuit: this is not a fault, but corresponds to a
normal function of the pump.
4. After having pumped dirty water, water containing sand or other abrasive material, the pump
should be rinsed with clear water.
