Replace the whole main filter after approximately 6,000 hours of operation and at least every
3 years.
To replace the main filter:
Remove the main filter according to Figure 16.
1.
Put the old filter in a large plastic bag, or wrap it in plastic foil, see Figure 13.

3.
Caution! Risk of equipment damage.
It is important that no dust, objects or debris are allowed to fall down into the inlet of the side
channel fan.
9.3.2
Individual filter bags
Replacing individual filter bags is possible, but we recommend replacing the whole filter
package, including the filter panel and locking rings, as it is quicker and causes less spreading
of dust.
Individual filter bags which have been damaged may be replaced, see Figure 14. Use a robust
screwdriver to detach the plastic locking ring.
The coiled spring may be kept for use with the new filter bag, but a new locking ring is to be
used to secure the new filter, see Figure 15.
NOTE!
