17. Fix the power cable to the lifting wire by a cable
clamp approximately 0.8 m above the mixer. This
prevents 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 a snap hook. See
fig. Attaching the power cable to the lifting wire.
Attach the power cable to the lifting wire by cable
clamps placed at 1 m intervals.

Mounting the lifting wire in the drum
At least three turns of wire must always
remain on the drum. Otherwise, the
wire may break loose from the drum
fixation.
Follow the separate installation and op-
erating instructions for cranes.
19. Lift the complete mixer, motor bracket with motor,
using the crane and slide it over the column
profile.
20. Slowly lower the mixer into the tank and down to
its position on the depth blocker.
21. Mount the cable sock (18) to the top fixation
bracket using the shackle and pull the power
cable through it to the desired position. See fig.
Top fixation bracket with lifting and safety wires
and cable sock. The power cable must be slightly
tightened.

The fixation of the propeller blades is en-
sured by the pressure of the clamping jaws
which are tightened by the bolts (3) and
the nuts (5). The function of the pin (1) is
to position the blades in the right angle be-
fore tightening the clamping jaws.
1. Check the premounted pins (1). They are used
only for positioning.
2. Tighten the screw (2) to widen the opening of the
clamping jaws.
3. Insert the blade from above. Turn it slightly and let
it rest on the pin. Turn the blade back until the
blade slides down and is flush with the hub.
4. Remove the screw (2).
5. Put Loctite 243 on the thread of the bolts (3).
6. Mount bolts, washers and nuts (3, 4 and 5) in both
holes and tighten by hand.
7. Tighten the two nuts (5) with a torque wrench to
100 Nm (A4-80).
8. Make sure that the blade corresponds to position
A in fig. SFG.xx.180/230.
9. Apply silicone to the joint between the blade and
the hub.

5.3.7 Mounting the propeller blades of SFG.xx.150
The fixation of the propeller blades is en-
sured by the pressure of the clamping jaws
which are tightened by the screws (3). The
function of the set screw (2) is to position
the blade in the right angle before tighten-
ing the clamping jaws.
The blade can be placed in three different angles.
Choose the right angle depending on the stirring
power and liquid density. When in doubt, use the
middle position.
The propeller blades must be mounted in
the same position to avoid the propeller as
well as the installation to be loaded un-
evenly.
