Installation and electrical connection
9. Clean the fill opening screw plug, replace the seal ring and screw it back in. Max. tight-
ening torque: 8 Nm (5.9 ft·lb)!
10.Reapply corrosion protection: Seal screw plug, e.g. with Sikaflex.
The mixer is lowered into the basin using a lowering device. The lowering device's guide pipe
leads the mixer safely to the operating point. The resultant reaction forces are transferred
via the lowering device directly into the foundation. The foundation must be dimensioned
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 (lowering 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!
