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.

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.

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.

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.
