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
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 A.C. motors are equipped with a built-in thermal cut-out in the windings.
6. Initial Start-up
Caution
Unscrew the ring nut and lift off the transparent lid. Slowly fill
the pump with clean water until the water level reaches the
inlet connection. Put on the transparent lid and tighten the
ring nut by hand. 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.
7. Maintenance
Caution
The strainer basket must be cleaned at regular intervals. A
full or dirty strainer will impair the pump's flow rate and the
filtration. For longer periods of downtime we highly
recommend to completely drain the pump and clean it.
Do not add water treatment agents, particularly agents in
tablet form, into the strainer basket!
Caution
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.
