Installation with lowering device
The mixer is lowered into the basin using a lowering device. The lowering device’s guide
pipe safely guides the mixer to the duty point. The resultant reaction forces are trans-
ferred directly into the foundation via the lowering device. The foundation
must
be de-
signed to bear this load!
CAUTION! Material damage due to incorrect accessories! Due to the high reaction
forces, the mixer may only be operated with the manufacturer’s accessories (lower-
ing device and frame). If the mixer is ordered for installation with a lowering device,
the frame comes pre-assembled. If the mixer is delivered without a frame, order the
appropriate frame from customer service!
