The suction pipe dimensions in the table are only valid for suction pipes not
longer than 5 m.
With longer pipes the flow resistance increases and suction is impaired. Danger
of cavitation is also increased. Make sure that the suction line is not leaky,
otherwise the pump will prime insufficiently or not at all.
The transparent lid must be screwed on tightly and the suction/intake line
should be as short as possible. This will reduce priming time, which is depen-
dent on the air volume in the intake line. If the intake line is very long this may
take up to 12 minutes. If possible the intake line to the pump should be installed
below the liquid level. Whenever the pump is installed above the liquid level it is
recommended to install a foot valve in the intake line. Thus the suction pipe
cannot drain itself when the pump has been turned off. This keeps priming
times short e.g. after having cleaned the strainer basket (143).

Electrical: All electrical connections should be performed by a qualified
expert only!
Before carrying out any electrical work or maintenance, the electricity supply to
all parts must be switched off.
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.
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 sup-
ply circuit has to be protected with a fault current contactor with a nomi-
nal fault current of I
ΔN
≤ 30 mA.
According to the norm, electrical wiring H05RN – F, H07RN – F 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.

Initial Start-up
6.1
Loosen the ring nut (160) above the strainer basket (143). Slowly fill the pump
with clean water until the water level reaches the inlet connection.
