5. Electrical Connection
All electrical connections should be performed by a qualified expert only!
Make sure all parts are free of tension before doing any maintenance work or electrical work.
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
∆
N
≤
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. In accordance with norm
requirements an electrical cable type H05RN-F or H07RN-F must be used. Please ensure that the diameter
of the electrical cable used adequately accommodates for the power of the motor and the length of the
cable. Pumps with single-phase motor are equipped with a built-in overload switch.
6. Initial Start-up
Slowly fill the pump until the water level reaches the outlet connection.
Never operate the pump without
water even when checking the rotation direction of the motor!
Ensure that all valves in 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.
7. Maintenance
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 line.
The pump is to be thoroughly drained and cleaned after extended periods of storage or down-time.
If there is danger of freezing during prolonged periods, the pump
must be drained ahead of time. For this purpose remove the suction
hose in order to drain off all liquid. Drain all pipes subject to freezing.
Before doing any maintenance work, switch off the pump and
disconnect it from the power supply.
