2. SAFETY INSTRUCTIONS
Hydrotech Discfilters in the HSF2600 series are designed for safe operation provided that they are installed correctly and used in accordance with the enclosed instructions. The equipment must be installed correctly and adapted in accordance with local regulations. The machine equipment is intended for use by multiple operators. You must read the applicable chapters in this manual prior to using the equipment or performing maintenance.
⊲ Pay attention to all warning symbols that appear in this manual. If this information is ignored
it may result in serious personal injury and/or damage to equipment.
⊲ Assume all electrical equipment to be live.
⊲ Assume all hoses and pipes to be pressurized.
⊲ Before carrying out maintenance work, the main power switch (see Figure 2.3) must be turned
to the OFF (0) position and locked with a padlock.
⊲ Maintenance and service may only be performed by authorised personnel.
⊲ Adequate lighting should be used while operating the filter and when working in close prox-
imity to the filter.
2.1 Warning symbols
Figur 2.1
Warning symbols are used in this manual to draw attention to potentially dangerous situations:
Information that warns you of a potential risk of personal injury and/or damage to equip­ment.
Warning decals (see Figure 2.1) are attached to the filter to warn personnel and serve as a remin­der to keep hands and fingers away from moving parts of the filter.
2.2 CE marking
Figur 2.2
This equipment is CE marked (see Figure 2.2), which guarantees that the equipment is designed, manufactured and described in accordance with the requirements set out in the EU Machinery Directive.
2.3 Conversion
The CE marking does not include any components that are not approved by Hydrotech AB and which are used in conversion/reconstruction of the equipment.
The warning symbols and CE marking must be attached where they are fully visible. If any part of
6
Operation & maintenance manual, Discfilter HSF2600 - 1F series with PFLC
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 Demands on personnel
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 switch (see the markings in Figure
2.3).
In the event of a power outage, turn the main switch to the OFF position (0) 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. Also see Appendix A in the “Automation manual”.
The filter tank must be connected to earth.
The main power switch/emergency switch must be fitted in accordance with applicable regula­tions.

2.7 Safety instructions
The filter is activated by turning the main power switch to the ON position (1), then selecting AUTO, REMOTE or HAND mode using the operating mode selector located on the front of the electrical cabinet.
NOTE! See instructions in section 5.1.
Turn the main power switch to the OFF (0) position and lock it with a padlock before per-

forming any work on the filter.
Access to the filter by unauthorized persons is strictly prohibited. Outdoor installations must be fenced in.
The filter can start rotating without warning if automatic control is activated. Moving parts must not be touched.
Safety guards are fitted around the power transmission. Make sure these are secured and cor­rectly fitted.
The aerosols from the backwash water may contain harmful substances.
Measured noise levels from the filter are less than 74 dB(A). Personnel should use appropriate protection, when necessary, in accordance with local 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. 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 panel and the control panel touch screen.
⊲ If the filters are delivered inside plastic covered wooden crates, a special type of corrosion may
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.
