18. Fix the power cable to the lifting wire by means of a cable
clamp approx. 2.6 ft (0.8 m) above the flowmaker. This will
prevent the cable from falling down and becoming entangled
in the propeller during operation. Connect the cable clamp to
the lifting wire above the wire clamp by means of a snap hook.
See fig. 22. Attach the power cable to the lifting wire by means
of cable clamps placed at 3.3 ft (1 m) intervals.

19. Position the crane in the foot, and mount the lifting wire in the
drum of the winch.
Always leave at least three turns of wire on the drum.
Otherwise the wire may break loose from the drum
fixation.
Follow the separate installation and operating
instructions for cranes.
20. Lift the complete flowmaker and the motor bracket with motor,
using the crane and slide it over the column profile.
21. Slowly lower the flowmaker into the tank and down to its
position on the depth blocker.

22. Mount the cable sock (18, fig. 23) to the top fixation bracket
using the shackle, and pull the power cable through it, to the

tightened.

Remove the lifting wire from the crane before starting
the flowmaker.
23. Remove the lifting wire from the winch and fit it to the wire
clamp (20) on the top fixation bracket.
24. Use the lifting wire as a relief for the power cable. For this
reason, always tighten the lifting wire. See fig. 22.
25. Check the distance between the propeller and the wall and the
propeller and the bottom of the tank when the motor bracket is
resting on the depth blocker. The flowmaker must under no
circumstances touch other installations, the bottom or the
wall.
DANGER
Electric shock
Death or serious personal injury
- Before making any electrical connections, make
sure to remove the fuses or switch off the main
switch. Make sure that the power supply cannot
accidentally be switched on.
26. Connect the power cable to the terminals in the control
cabinet.
