protectors, be aware of the
risk of unexpected starts in
connection to overload. Do
not use such motors for
fire-fighting
and sprinkler systems.
NOTICE:
Only
use
motors with a half-sized key in the
shaft extension (IEC 60034-14) and
with normal vibration rate (N).
The mains voltage and frequency
must agree with the specifications on
the data plate.
In general, motors can operate under the following
mains voltage tolerances:
Frequency Hz
Phase ~
50

3
Use cable according to rules
(2+earth/ground) for single phase versions and with
4 leads (3+earth/ground) for three-phase version.
4.3 Install the pump
4.3.1
Mechanical installation
Check the following before installation:
Use a concrete of compressive strength
class
C12/15
requirements of exposure class XC1 to
EN 206-1.
The mounting surface must have set and
must be completely horizontal and even.
Observe the weights indicated.
Install the pump set
For examples of horizontal and vertical installations,
see Figure 12 on page 97.
Check that the foundation has been prepared in
accordance with the dimensions given in the outline
drawing/general arrangement drawing.

Position the pump set on the foundation and
level it with the help of a spirit level that is
placed on the discharge port. The permissible
deviation is 0.2 mm/m.
2.
Remove the plugs covering the ports.
3.
Align the pump and piping flanges on both sides
of the pump. Check the alignment of the bolts.
4.
Fasten the piping with bolts to the pump. Do not
force the piping into place.
5.
Use

6.
Tighten the foundation bolts evenly and firmly.
Note:
If the transmission of vibrations can be
disturbing,
supports between the pump and the
foundation.
4.3.2
Piping checklist
Check that the following are adhered to:
The suction lift line has been laid with a
rising slope, at positive suction head line
the
with a downward slope towards the
pump.
The nominal diameters of the pipelines
are at least equal to the nominal
diameters of the pump ports.
The pipelines have been anchored in
close
connected
stresses or strains.
CAUTION:
Welding
impurities in the piping damage the
of
pump.
Free the piping from any impurities.
If necessary, install a filter.
