Electrical: All electrical connections should be performed by a qualified
expert only!
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. This pump is built according to Protection Class 1.
The ambient temperature must not exceed max. 40°C. Pumps with three-phase
motors require the installation of a correctly adjusted motor overload switch.
Observe the data on the rating plate. Non-compliance will void any warranty in
case of motor failure. Pumps with A.C. motors are equipped with an overload
protection switch as standard.
The motors are built according to thermal class F, the ribs may achieve tempe-
ratures up to 70°C.
Caution: 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. Please consult your licensed electrician!
The supply circuit has to be protected with a fault current contactor with a
nominal fault current of I

≤
30 mA zu schützen.
The electrical wiring used (HO5RN – F for inside, HO7RN – for outside) must

Initial Start-up
6.1
Loosen the ring nut (160.2) above the strainer basket (143) by turning
anticlockwise, if necessary one can use a closed folding ruler as opening
device by placing it between the cams of the ring nut. Remove the transparent
lid (160.1). Slowly fill the pump with transported medium until its level reaches
the inlet connection. Put on the transparent lid (160.1) and make sure that the
o-ring seal (412.1) is well in the housing groove. Tighten the ring nut (160.2) by
hand. Otherwise the pump will prime insufficiently or not at all.
Never let the
pump run dry, not even for the purpose of checking the direction of
rotation!
6.2
Make sure pump and motor turns freely, especially after extended periods of
downtime. To do this put a screwdriver into the slot at the fan end and turn it by
hand in the direction of rotation (see directional arrow). If necessary remove the
fan cover and turn the fan by hand. Make sure the mechanical seal doesn’t
leak.
