All electrical connections should be performed by a qualified expert only!
The use of pumps for swimming pools and the restricted area around them is only permitted if
pumps are installed in accordance with DIN/VDE 0100 part 702. The supply circuit has to be
protected with a fault current contactor with a nominal fault current of I

30 mA.
Please make sure that the electrical installation has a disconnecting device, which allows
disconnecting from the power supply with a minimum of 3 mm contact gap at each pole. According
to the norm, electrical wiring H05RNF, H07RNF respectively must be used. In addition to that
the permissible minimum cross section must be adapted to the motor power and to the cable
length. Pumps with A.C. motors are equipped with a built-in thermal cut-out in the windings.

6. Maintenance
Caution
Slowly fill the pump and the suction line with water.
Never let the pump run dry, not even to
verify the direction of rotation!
Ensure that the valves installed on the suction and pressure
lines are completely open. Before initial start-up and after extended periods of downtime make
sure the pump shaft turns freely.
Before carrying out any maintenance work, the electricity
supply to the pump must be switched off. Close the shut-off
valves on the suction and on the pressure side. The strainer
basket must be periodically emptied. A full or dirty strainer will
impair the pumps flow rate and the filtration. The pump is to
be thoroughly drained and cleaned prior to the unit not being
in use for a longer period of time.

If there is a risk of freezing, the pump must be drained
ahead of time. For this purpose open the drain plug in order
to drain off all liquid. Also drain all pipes subject to freezing.
Before doing any maintenance work, switch off the pump
and disconnect it from the power supply.
