fourth screw should be loosened only to such a degree, that the terminal box
cover can be swung aside. The terminal box frame must remain attached to the
motor housing.
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.
The pumps are designed for permanent electrical connection.

First Start-up
6.1
CAUTION
Series BADU 21:
Slowly fill the pump with clean water up to the pressure connection. Never allow
the pump to run dry! Not even just to check the direction of rotation! Run-
ning dry will destroy the mechanical seal.
Series BADU FA 21:
Detach the cover of the lint catcher (160.3). Slowly fill the lint catcher/pump with
clean water up to the suction connection. Please make sure that the sealing sur-
faces on the cover (160.3) and in the filter housing (124) are clean. Afterwards
insert the o-ring (412.10) in the filter housing sealing groove. Then put the cover
(160.3) on straight and tighten the 4 palm knobs (925) uniformly, making sure
that tight contact is made. Otherwise the pump will not be able to suck at full
power.
Never allow the pump to run dry - not even in order to check the direction
of rotation.
6.2
CAUTION
Check pump for smooth running after a longer downtime or storage time by
inserting a screwdriver into the slot at the end of the motor shaft (fan side) and
turning by hand in the direction of motor rotation. Or, if necessary, remove the fan
cover and also turn the impeller by hand in direction of motor rotation. After start-
ing up, check that the mechanical seal is watertight.
6.3
CAUTION
Never operate the pump without the strainer basket (143), otherwise the pump
may get clogged and blocked.
6.4
When starting a pump with three-phase current motor for the first time, make
sure the motor turns in the direction of the affixed arrow (anticlockwise, seen from
the fan). If the motor rotates in the wrong direction, two phases must be switched
(by a licensed electrician only!).
