available power supply;
•
there are no signs of damage to the pump or its power cord;
•
the electric connection is made in a dry place, protected against any risk of flooding;
•
the electric system is complete with a residual current circuit-breaker (I ∆n ≤ 30 mA) and an
efficient earthing connection;
•
Any extension cords must comply with the requirements of the DIN VDE standard 0620.
4. RECOMMENDATIONS
To ensure the proper operation of the pump, it is important to comply with the following
recommendations:
