The single-phase motors are equipped with built-in thermal overload protection and can be connected directly to the mains. NB: if the
•
motor is overloaded it stops automatically. Once it has cooled it starts again automatically without requiring any manual intervention.
Do not damage or cut the power supply cable. If this should occur, have the repair or replacement carried out by specialised,
•
qualified personnel.
The length of the power cable on the pump limits the maximum depth of immersion in use of the pump.
8. START-UP
The pump has an adjustable electronic level sensor for operation in automatic (Fig.7, page 2) or manual mode (Fig.8, pag.2).
By shifting the cursor (in 10 mm steps) to one of the available positions on the ON-AUTOMATIC SCALE (Fig. 7) it is possible to choose the water
level at which the pump is to be started.

By shifting the cursor to manual position (Fig. 8) the pump starts/stops when the plug is inserted/removed from the socket.
9. PRECAUTIONS
RISK OF FROST: when the pump remains inactive at a temperature lower than 0°C, it is necessary to ensure that there is no water
•
residue which could freeze, causing cracks in the plastic parts.
If the pump has been used with substances that tend to form a deposit, rinse it after use with a powerful jet of water in order to avoid
•
the formation of deposits or encrustations which would reduce the characteristics of the pump.
Ensure that the float switch does not touch the walls of the trap during operation.
•
Ensure that the OFF level is not too close to the suction grid, minimum height below the filter 60/70mm.
•
10. MAINTENANCE AND CLEANING
In normal operation the pump does not require any type of maintenance. The pump may not be dismantled except by skilled and qualified
personnel, in possession of the qualifications required by the specific regulations on the subject. In any case, all repair and maintenance work
must be carried out only after having disconnected the pump from the supply mains.
When restarting the pump, ensure that the suction filter is always fitted so as not to create the risk or possibility of accidental contact with moving
parts. If the pump has been used with substances that tend to form a deposit, rinse it after use with a powerful jet of water.
10.1 Cleaning the suction grid

11. MODIFICATIONS AND SPARE PARTS
Any modification made without prior authorisation relieves the manufacturer of all responsibility. All the spare parts used in repairs must
be authentic and all accessories must be authorised by the manufacturer, in order to ensure maximum safety of the machines and of
the systems in which they may be installed.
If the power supply cable of this appliance is damaged, the repair must be carried out by specialised personnel to prevent all risks.
