9.2.FLOAT SWITCH SETTING
By lengthening or shortening the stretch of cable between the float and the fixed point (Float
locking) it is possible to regulate the level at which the pump switches off. Ensure that the float
switch can move freely when the pump is operating.
Make sure the stop level does not uncover the filter.

10 PRECAUTIONS
•The suction filter must always be present when pump is operating.
•The pump must not be started more than 30 time in one hour so as not to subject the motor to ex
cessive thermal stress.
•DANGER OF FROST: When the pump remains inactive at temperatures of less than 0°C, it is
necessary to ensure that there is no water residue which might freeze, and cause cracking of the
pump components.
• If the pump has been used with substances that tend to deposit, rinse it after use with a powerful
jet of water so as to avoid the formation of deposits or scale which would, tend to reduce
the pump characteristics.

11 MAINTENANCE AND CLEANING

In normal operation the pump does not require any type of maintenance, thanks to the oil bath
lubricated seal and to the greased-for-life bearings.
The electropump can only be dismantled by skilled and qualified personnel, in possession
of the technical qualifications required by the specific regulations in force.

In any case, all repair and maintenance jobs must be carried out only after having disconnected
the pump from the power mains, once made sure that it cannot suddenly begin working.During
dismantling it is necessary to pay great attention to sharp parts which may cause injury.The cutting
edge flange of the electropump is provided of aspiration fans. It is advisable, every now and then,
to clean these fans to avoid a loss of efficiency. Best cleaning is obtained through a throw of water.
Sand and other abrasive materials cause precocious wear and tear, as well as loss of performances.
