Wilo EMU FA+HC20.1 Series Installation And Operating Instructions Manual page 29

A suspension unit must be installed for wet installation. This must be ordered separately from the
manufacturer. The pipeline system on the discharge side is connected to this. The connected pipe-
line must be self-supporting, i.e. it should not be supported by the suspension unit. The operating
area must be laid out so that the suspension unit can be installed and operated without difficulty.
For maintenance and/or repair work, the machine must be taken out of the operating area. The
suspension unit makes this possible at any time.
The machine must be completely submerged in pumped liquid up to the
top edge of the pump housing.
- Install the suspension unit in the operating area (Only use a suspension unit produced by the
manufacturer. Information about installation is located in the appendix of this operating
manual.).
- Prepare the machine for operation on a suspension unit.
- Check that the suspension unit is firmly fixed and functions properly.
- Have an expert connect the machine to the power supply and check the direction of rotation
in accordance with chapter 6.
- Lower the machine slowly onto the guide pipes in the operating area. Hold the electric power
cables slightly taut when lowering. When the machine is connected to the suspension unit,
make sure that the electric power cables are secured adequately against falling and/or
damage.
- For new installation: Flood the operating area and bleed the discharge pipe.
- Start the machine in accordance with chapter 6.
