6. ELECTRICAL CONNECTION
The length of the power cable limits the maximum depth of pump immersion.
Follow the indications on the technical data plate and technical specications on page 3.
7. START-UP
Automatic operation (A):
1) Insert the plug of the power cable in a 115 – 120V power socket.
2) The pump will start up; ensure that it is immerse in the liquid to be pumped.
Attention: The pump will not automatically switch off once it reaches the minimum level.
It must be switched off manually by the user, either by taking the power out of the socket.
The maximum suction level is reached only during manual operation.
8. PRECAUTIONS
RISK OF FREEZING: when the pump remains inactive at a temperature lower than 32º F, 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 deposits, or with
water containing chlorine, rinse after use with a powerful water jet in order to avoid the
formation of deposits or coatings which would reduce the performance of the pump.
9. 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
power supply. When restarting the pump, ensure that the suction lter is always tted so as
not to create the risk or possibility of accidental contact with moving parts.
9.1 Cleaning the suction grid
(Fig. 3)
• Switch off electric power to the pump (a).
• Drain the pump.
• Unscrew the screws on the lter (b).
• Remove the suction grid (c).
• Clean and reassemble the suction grid.
9.2 Cleaning the impeller
(Fig. 4)
• Switch off electric power to the pump (a).
• Drain the pump.
• Unscrew the screws on the lter (b).
• Remove the suction grid (c).
• Wash the pump with clean water to
remove possible impurities between
the motor and the pump jacket (d).
• Clean the impeller (d).
• Check that the impeller can turn freely.
• Reassemble parts in inverse order of disassembly.
