3. Receiving the product
3.1 Transporting the product
The individual components of the pump must be
packed carefully to prevent any damage to the
surface protection during transportation.
All lifting equipment must be rated for the purpose
and checked for damage before any attempts to lift
the components are made. The lifting equipment
rating must under no circumstances be exceeded.
3.2 Inspecting the product
On delivery, the pump and any accessories supplied
with it must be checked for transport damage. This
also applies when the equipment is delivered to the
installation site.
If the pump or any accessories have been damaged
during transportation, contact your local Grundfos
company before continuing to install the equipment.
Do not dismantle a damaged new component for
further inspection, unless instructed by your local
Grundfos company.
The packaging material must be disposed of
according to local regulations.
3.3 Storing the product
The pump must be stored in a dry location in which
the temperature is not subject to major fluctuations.
If the pump has been stored for more than one year,
the gearbox oil must be changed. The oil must be
changed even if the pump has never been in use.
This is necessary because of natural aging of
mineral oil lubricants.
4. Installing the product
During installation, the pump must only be lifted
when using the suspension point.
The lifting equipment supplied with the pump as well
as the wire used for lifting and lowering the pump
into the tank must not be used as universal lifting
equipment.
4.1 Positioning
Correct positioning of the pump is essential to
ensure trouble-free operation and long life. The
following guidelines must be observed:
• If more pumps are installed in the same tank,
they must not generate opposite flows.
• The distance from the centre of the pump to the
tank bottom (Hmin) must be equal to the impeller
diameter. See fig. 1.
• The distance from the top of the pump rack to the
liquid surface (HABOVE) must fulfil one of the
following two requirements:
– For pumps with vortex shield, the distance
must at least be equal to the impeller diameter.
– For pumps without vortex shield, the distance
must at least be equal to 1.5 times the impeller
diameter. See fig. 1.

4. Drill the holes for the mounting screws for the top
fixation bracket in the concrete.
5. Mount the screws and fit the top fixation bracket.
6. Depending on the length of the column profile,
weld the turnable part of an intermediate fixation
bracket to the column profile.
Fig. 5 Top fixation
7. Position and align the column profile with the
profile section on the connection flange. Shorten
the column profile (pos. 2) to the correct length to
match the position of epoxy insulator (pos. C) at
the top fixation bracket. A gap of 5 to 10 mm
between collar of epoxy and column profile is
optimal. See fig. 5.
8. Remove the epoxy insulator and the turnable
metal part by removing the centre screw (pos. A)
and the two fixation screws (pos. B).
9. Adapt the outside of the square epoxy insulator
to the inside of the column profile. The epoxy
insulator must fit tightly inside the column profile.
10. Place the column profile on the profile section on
the connection flange and mount the top end with
the epoxy insulator and the turnable metal part
on the already installed top fixation bracket.
Tighten the three screws (pos. A) and (pos. B) in
the desired position. It is possible to adjust the
angle in steps of 7.5 °.
11. Fit an intermediate fixation bracket to the
turnable part welded on to the profile tube in step
6. Drill holes in the tank wall, fit screws in the
bracket and tightening the screws.
12. Drill the holes for the mounting screws for the
crane foot in the concrete.
13. Mount the crane foot and fit and tighten the
screws.
14. Mount the lifting wire on the pump rack using the
shackle. See fig. 6.
Fig. 6 Mounting of lifting wire on the pump rack
15. Mount the top end of the safety wire to the hole
(pos. 31, fig. 5) of the top fixation bracket by
means of a shackle. The other end of the safety
wire ends in a shackle through which the lifting
wire must run.
Fig. 7 Safety wire
16. Fix the power supply cable to the lifting wire by
means of a cable clamp approx. 0.8 m above the
pump. This will prevent the cable from falling
down and becoming entangled in the impeller
during operation. Connect the cable clamp to the
lifting wire above the wire clamp by means of a
snap hook. See fig. 8. Attach the power supply
cable to the lifting wire by means of cable clamps
placed at 1 m intervals.

22. Connect the power supply cable to the terminals
in the control cabinet.
4.4 Electrical connection
The electrical connections must be carried out by a
qualified electrician in accordance with local
regulations.
All national and local regulations relating to safety
and accident prevention must be observed.
The supply voltage and frequency are marked on the
pump nameplate. Make sure that the pump is
suitable for the power supply available at the
installation site.
The pump is supplied complete with a power supply
cable of 10 m (standard length, suitable for up to 7 m
deep tanks). Standard cable lengths are 10 and 15
m, longer cables are available on request. See
section 6.2 Identification.
The motor is marked either with a Y (star) or Δ
(delta). Make this connection in an external control
panel using conductors 1 to 6 of the power supply
cable.
Figure 10 shows a schematic drawing of these star
and delta connections. See also section 4.4.2 Wiring
diagrams.
If the pump is connected in delta during operation,
the pump can be started in a star-delta connection.
