Installation and electrical connection
DANGER
Risk of explosion due to incorrect installation!
Ensure the connection made between the motor plate and support structure is gas-
tight. If gases can escape, there is a risk of explosion! This work must only be carried
out by customer service or approved qualified specialists!
CAUTION
Material damage due to excessive bending stresses!
If the mixer shaft is not installed perpendicularly, it may be subjected to high bend-
ing stresses. These bending stresses can damage the mixer shaft and the gear. To
ensure perpendicular installation of the mixer shaft, install the motor plate precisely
using equalisation sheets.
Affix the drive unit, with the mixer shaft and hub mounted, to a suitable support struc-
ture. Once the mixer has been installed, attach the propeller blades.

1. Fasten the hoisting gear to the attachment points.
2. Slowly lift the mixer. CAUTION! Material damage! Place a soft surface under-
neath the mixer while lifting.
3. Position the mixer over the support structure.
4. Slowly lower the mixer. CAUTION! Material damage! Do not impact the support
structure heavily while lowering!

⇒ Make precise positioning adjustments by hand while lowering.
5. Lower the mixer until the motor plate rests completely on the support structure.
⇒ Check perpendicular alignment of the mixer shaft. If necessary, adjust the mo-
tor plate with equalisation sheets.
6. Affix the motor plate to the support structure. Tightening torque according to as-
sembly drawing!
7. Detach hoisting gear.
▶ Mixer is installed. Prepare and attach propeller blades.
Adjusting the setting angle
The setting angle of the propeller blades can be adjusted to adapt the mixer to the re-
quirements of the respective system. The following union inserts are included in the
scope of delivery for this purpose:
▪ Union insert for a setting angle of 30/45°
▪ Union insert for a setting angle of 35/40°
NOTICE
Different setting angles can cause malfunction
Attach all propeller blades with the same setting angle. Different angles may lead to
malfunctions.
