Class 1. The ambient temperature must not exceed max. 40°C. Pumps with
three-phase motors require the installation of a correctly adjusted motor over -
load 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 supply circuit has to be protected with a fault current contactor with a
nominal fault current of I
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
CAUTION
Loosen the ring nut (160.2) above the strainer basket (143) by turning
anticlockwise, if necessary one can use the opening device (577). Place the
opening device according to the letters (A, B or C) which are to be found at the
opening device as well as at the ring nut (160.2), see drawing 1. Place the
opening device onto the ribs of the ring nut, as shown on drawing 1, until it
catches. Loosen the ring nut by turning anticlockwise, see drawing 2. Remove
the transparent lid (160.1). Slowly fill the pump with clean water until the water
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, do not use force. Otherwise the pump will prime
insufficiently or not at all. Never let the pump run dry, not even for the pur-
pose of checking the direction of rotation!
6.2
CAUTION
Before starting the pump, make sure the shut-off valve on the pressure side is
half closed! Only after reaching full speed, slowly open the shut-off valve and
adjust it to the operation point.
