Suction mode:
When the pump is mounted above water level, a foot valve must be installed in
the suction line. Access to the pump for the purpose of filling the pump housing
and the suction line before start-up must be guaranteed at all times. The suction
capacity is drastically reduced by flow resistance inside the suction line (in the
case of longer or too narrowly dimensioned pipelines). Thus the suction line
should be as short as possible. If the suction line leaks, the pump cannot prime
properly.

CAUTION
Danger of clogging
Series BADU 21:
If the possibility of clogging (leaves, straw, grass etc.) cannot be excluded, a
strainer must be installed into the suction or intake line.
Series BADU FA 21:
Series BADU 21 comes with an intake strainer installed into the lint catcher.

Electrical: All electrical connections should be performed by a qualified
expert only!
Make sure all parts are free of tension before doing any maintenance work or
electricians work.
Please make sure that the electrical installation has a disconnecting device,
which allows disconnecting from the power supply with a minimum of 3 mm con-
tact 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. AC motors of series BADU 21-41.. and BADU FA 21-40/..
come with that type of motor protection switch or with a thermal cut-out; for all
other types of series BADU 21 and BADU FA 21 such a switch must be provided
by the user.
The motors are built according to thermal class F, the ribs may achieve temper-
atures 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
When connecting or changing electrical leads for motors of series BADU 21-40/..,
