CAUTION
Please make sure that the installed shut-off valves in the suction and pressure
lines are completely open. The pump must never run with shut-off valves closed.

Maintenance and Repair
7.1
CAUTION!
Series BADU FA :
The suction strainer in the lint catcher must be cleaned periodically. If the strainer
is full or clogged, the pumpʼs rate of flow will diminish and filtration will be insuffi-
cient. Furthermore, there is danger of cavitation which may cause severe dam-
age to various parts of the pump.
Cleaning the strainer:
1. Shut down pump.
2. Close shut-off valves.
3. Open ring nut (160.2). Remove strainer basket (143), clean and replace it.
Close lid (see points 6.1 and 6.3)
4. Open shut-off valves.
5. Restart pump.
7.2
CAUTION
When the pump is shut off by the thermal security in the windings or by the motor
overload switch, the power supply must be cut off and one must check whether
the pump can still turn unobstructed. To do so try rotating the motor shaft at the
fan side with a screwdriver or other tool that will do. If rotating the motor shaft
requires considerable force, the pump must be checked by an expert. If it rotates
easily, remove your tool and restore the power supply. As soon as the motor has
cooled down, the thermal security in the windings will reactivate itself, respec-
tively the motor overload switch can be pressed down. This only may happen
one more time. Please check the current consumption! If the pump still shuts off
because of the thermal security in the windings or because of the motor overload
switch the cause of the malfunction is to be determined by an expert (e.g. block-
ing of the pump due to impurities or sand swept up while vacuuming the bottom
of a pool). Check current supply and fuses.
7.3
CAUTION!
If the pump seizes, it has to be cleaned. Repeated starting of a blocked pump
may cause damage to the motor. In that case any guarantee is voided!
