. SAFETY INSTRUCTIONS
2.
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.
⊲ Consider all hoses and pipes to be pressurised.
⊲ 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.
2.1 Warning symbols
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 labels (see Figure 2.1) are attached to the filter to warn personnel and
act as a reminder to keep hands and fingers away from the filter’s moving parts.
2.2 CE marking
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 extend to any components that are not approved by Hydrotech AB
and that are used in conversion/reconstruction of the equipment.
The warning symbols and CE marking must be attached in such a way that they are fully visible. If
any part of 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
In order to avoid personal injury and damage to the equipment, service and maintenance
may only be carried out by personnel that have been trained to use the equipment and are
conversant in local regulations. 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 main-
tenance and set-up before operation.

2.5 Emergency stop
The filter is equipped with an emergency
stop and a main 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 unintention-
ally 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 I.
The filter tank must be connected to earth,
see section6.4 in the "Reception & Installa-
tion Manual".
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 or HAND mode using the mode selector located on the front of the electrical cabinet.
The filter stops if the mode selector is turned to the 0 (OFF) position.
NB See instructions in section 4.1.
Turn the main power switch to the OFF (0) position and lock it with a padlock before perform-
ing any work on the filter.
Access to the filter by unauthorised 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.

Two drum lifters are supplied unassembled for each installation, see Figure 3.4. These are only
used when servicing drum bearings. The supplier should be contacted when servicing bearings.

. START UP AND OPERATION
4.
4.1 Check procedures during start-up
1. Check that the drive unit cover is installed correctly.
2. Set the pump switch to the 0 (OFF) position, see Figure 4.1.
3. Set the main power switch to the 1 (ON) position.
4. Set the mode selector to HAND mode.
5. Open the water supply partially so that water slowly flows into the filter drum. Make sure
that the difference in water level between the inside and outside of the filter drum does
not exceed 450 mm (see section 4.2.1). If the filter cover becomes clogged, it may be nec-
essary to fill the filter tank with water from an external source or to remove a filter panel
and allow unfiltered water to fill the filter tank.
A difference in water level between the inside and outside of the filter drum greater than
450mm will damage the filter.
6. When the water level inside the filter tank is above the pump suction pipe (or the pump if
a CRK or MTR pump is installed), the pump must be started by turning the pump switch
to the 1 (ON) position.
NOTE Also read section 2.7 (Safety instructions).
The backwash pump must not be started until the water level has reached the suction pipe
(or pump if a CRK or MTR pump is installed), otherwise the pump will run dry and fail.
7. If the water level inside the filter tank reaches the overflow wall, set the mode selector to
the AUTO position (see section 4.2).
8. Fully open the water supply.
The filter is now run in the mode for automatic level control. It may be necessary to adjust the
level sensor so that the filter can be run optimally.
