V. OPERATION
5.1- Intended use
1. Cellar drainers are submersible pumps intended for domestic use.
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 and dirty water with particles in suspension that are less
than [see specifications in Table 1] in diameter.
3. The pump is fully submersible: the immersion depth must not exceed 5m (refer to the technical
characteristics table).
4. The pump should not be used for sucking up liquids or materials that are corrosive, combustible
or explosive; fats, oils, waste water from toilet...
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.
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,
Connect pump to mains power
Raise the float switch to start the pump, lower it again to stop the pump.
In this case, the minimum pumping water height may be reduced.
5.2.3- Warning!
Never operate the pump empty (without water).
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.
5.3- Advise for users
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 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.
