Operation and maintenance, Discfilter HSF2600 - 2,3 series with PFLC
6.7.3 Changing filter panels
It is important to maintain the balance of the
drum when changing filter panels. Remove/
refit every other filter panel. This prevents un-
intentional rotation of the drum and reduces
the load on the drive chain and gearbox.
NEVER remove or refit all the filter panels only on ONE side of the disc (see figure 6.23).
1. Turn the mode selector to “HAND” and lift the filter cover on the backwash pipe side, see sec-
tion 6.1.
2. Select “Service” on the operator panel, see Figure 6.24.
3. Select “Pump & Drum”, see Figure 6.25. Use the “Jog Fwd” and “Jog Bwd” buttons to set the
drum in the desired mode, see Figure 6.26.
4. Turn the main power switch to the OFF (0) position and lock with a padlock.
5. Undo the filter segment cover screw and re-
move the cover, see Figure 6.27.
6. Pull out the filter panel.
7. Insert a new filter panel and press in until it
touches the bottom.
The filter panels MUST be installed with the filter medium inwards and the frame outwards
as shown in Figure 6.28.
8. Re-fit the filter segment cover (see Figure 6.27) and tighten the screw.
Maximum tightening torque: 3 Nm.
9. Close the filter cover.
10. Start operation again as set out in section 4.1.
