No people or animals are allowed in the water where the pump is operating.
Operation of the pump is prohibited if the insulation of the power cable or the float
switch cable is damaged. If this is the case, contact the guarantee company to have the
cable replaced. Mechanical damage is not subject to free of charge warranty repairs.
Operating the pump with damaged cable insulation will result at best in water damage
to the motor and at worst may cause an electrical shock
Before starting the pump, it is essential to check the voltage at the end of the cable.
Note that as the length of the cable increases, the supply voltage at the end of the cable
decreases. The permissible voltage drops for the motors used are ±6%.
In order to protect against excessive voltage drop, the correct choice of cable must be
observed, depending on the type of power supply (single or three-phase), motor power
and cable length. Below is a table to help you make the right choice of cable:
