4.3 Starting and stopping
The automatic control starts and stops the pump when a defined level is reached.
The length of the float is set at the factory.
Never change this setting.
When changing the float, please observe this setting.
4.4 Starting frequency
To prevent engine overheating and excessive stress on the engine, seals and bearings, limit the
number of starts to 10 per hour.
4.5 Operations required for commissioning
Check the various points on the check-list (described in paragraph 3.6).
• Check the sump for cleanliness (no debris and foreign matter).
• Check that the discharge diameter is appropriate for the installation.
• Check that the power supply circuit is earthed and protected by a 30 mA differential circuit
breaker.
• Check that the power cable is not cut or damaged.
• Check that the connection is only used to supply the pump.
• Carry out a functional test (switching on/off).
• Check the freedom of movement of the float.
• Check the correct functioning of the non-return valve.
• Check that the gravity flow of wastewater into the sump is correct.
• Check the correct functioning and ease of operation of the shut-off valves.
• Check the flow at the discharge outlet.
• If the sump is sealed, ventilation must be installed so that it is always at atmospheric pressure.
Air must flow in both directions.
4.6 Decommissioning
1. Close the valves on the supply pipes.
2. Drain the tank.
3. Close the discharge valve.
4. Switch off the electrical power supply and record the installation.
➜ The power supply is not cut. Risk of electric shock.
➜ Unplug the plug or disconnect the electrical conductors and take the
steps required to avoid inadvertent operation.
5. Inspect the hydraulic parts and shredding blades. Clean them if necessary.
6. Clean the tank.
