switch to the OFF (0) position to prevent the filter drum from unintentionally starting to rotate when the power is reconnected.
2.6 Electrical safety
Electrical installation must be carried out by a qualified electrician and in accordance with local regulations. Also see Appendix D.
The filter tank or the frame must be connected to ground. Also see section 4.4.

3.1 Reception
Once the equipment has been delivered and received it must be checked for transport damage. Document any transport damage before further handling of the equipment.
The consignment note, manual and spare part kit are attached to the equipment.
Check all parts against the consignment note. Some parts may be delivered unassembled. Hand­le fragile parts with care. Before lifting the equipment, see section 4.1.
3.2 Storage
Some precautions must be taken to prevent damage to equipment if a long storage time is ne­cessary (several weeks or more):
⊲ The equipment should preferably be stored indoors, in a frost-free area.
⊲ The filter must be protected against direct sunlight if stored outdoors. Heat and UV radiation
can damage the filter panels.
⊲ If the filters are delivered inside plastic covered wooden crates, a special type of corrosion can
occur if stored outdoors, especially in coastal areas. The moisture inside the plastic acts as an anode and the exposed dry components as a cathode. In these areas, the filters must therefore be unpacked immediately upon delivery.
