Note
When the motor is switched on for the first time or restarted, the top speed
(2830 rpm) is always activated.
When switching via the switches or via the external contacts, the previo-
usly switched speed is not reactivated until approx. 5 min. have lapsed.
If the external control is not required, the cable ends of the control cable must
be isolated.

Initial Start-up
6.1
Loosen the ring nut (160.2) above the strainer basket (143) by turning
anticlockwise. 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 purpose of checking the direction of rotation!
6.2
Make sure pump 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. If necessary remove the fan cover and turn the fan by
hand. After re-starting make sure the mechanical seal doesn’t leak.
6.3
Never operate the pump without the strainer basket (143) and its handle
(danger of the suction strainer bobbing up), otherwise the pump may get clog-
ged and blocked.
6.4
Please make sure that the installed shutoff valves in the suction and pressure
lines are completely open during operation, since the pump must never be allo-
wed to run with shutoff valves closed!
7.
Maintenance / Repair
The strainer basket (143) must be periodically emptied. A full or dirty strainer
will impair the pump’s flow rate and the filtration.
Water purifying agents, especially in tablet form, must not be placed in
the pump strainer tank!
