7. ELECTRICAL CONNECTION
The length of the power cable on the pump limits the maximum depth of immersion in use of the pump.
Follow the indications on the technical data plate and in this manual, table 3.
8. START-UP
1)
Insert the plug of the power cable in a 230 V power socket.
2) When the float reaches the ON level the pump will start and will continue operating until it reaches the OFF
level.
Automatic operation (A):
3) The integrated float switch starts and stops the pump automatically when the indicator (2) is positioned on “A”.
Manual operation (M):
4) To start the pump, lift the knob (3) positioning the indicator (2) on “M”. In these conditions the suction level of the
pump will be down to 2-3 mm
5) In order to check the correct working and clean the float switch open the cover (1) positioning the knob (3) on
“O”
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, or with water containing chlorine, 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.
10. MAINTENANCE AND CLEANING
In normal operation the pump does not require any type of maintenance. 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.
