the equipment with a warning symbol is replaced, a new symbol must be attached in the same position. Damaged symbols and CE markings must be replaced immediately.
2.4 Personnel requirements
Only personnel trained for the equipment and conversant with local regulations may perform service and maintenance, in order to avoid personal injury and damage to the equipment. Ser­vice and maintenance personnel may only handle those parts of the equipment they have been trained for.
The operator may need to work inside the safety barrier and in the safety zone during mainte­nance and set-up before operation.
2.5 Emergency stop
The filter is equipped with an emergency stop and a main power switch (see Figure 2.3).
In the event of a power outage, turn the main power switch to the OFF (0) position to prevent the filter drum from unintentionally starting when the power returns.
2.6 Electrical safety
Electrical installation must be carried out by a qualified electrician and in accordance with local regulations.
The filter tank or the frame must be connected to ground. Also see section 4.4.
The main power switch/emergency stop must be fitted in accordance with applicable regulations.

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. Refer to section 4.1 before lifting the equipment.
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 and the control panel touch screen.
⊲ 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, filters must therefore be unpacked immediately upon delivery.
