General description
The machine is composed by three main parts:
  • Electric motor speed reducer
  • Light alloy base with adjustable feet, and wheels
  • Support column
These three parts can be easily assembled and disassembled for transportation. The support steel column can be angled with respect to the base. The motor support is mounted on rollers and ball bearings. The aluminium base can be easily fit on site by anchors, by suitable holding column or by vacuum using the appropriate accessory (see accessories). The machine can be used at any angle within the horizontal position by the appropriate fixing making sure that flushing water does not drop directly onto the motor . For internal use we suggest the machine is fit with a water collector system (see accessories, 83-C0350/5 Water collecting ring).
