Hold the drive unit firmly and align the drive unit with the weld plate. Apply the clamp ring without tightening it fully. The motor
must always be pointing upwards.

Adjust gear motor orientation in order for this to clear tank legs and according to section 8.8 Mounting angle. The motor must
always be pointing upwards. Tighten clamp ring according to section 8.9 Tightening torque for screwed connections.
Step 5
Ensure the upper part of the flange is flush with the lower side of the weld plate.
Step 6
CAUTION
Check for levitation!
Push the impeller downwards against the weld plate – possibly
using the lifting rod tool – the impeller should travel axially minimum
0.5 mm – otherwise it is not levitated correctly.
If not, ensure both bearings are installed correctly, flange is flush
against the bottom of the weld plate. Lubricate the bearings with
e.g. water and recheck levitation.
