9.3.1 Mainlter
Replace the whole main lter after approximately 6,000 hours of operation and at least every
3 years.
To replace the main lter:
1. Remove the main lter according to Figure 16.
2. Put the old lter in a large plastic bag, or wrap it in plastic foil, see Figure 13.
NOTE! Avoid dust spreading.
3. Install the new main lter.
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lterbags
Replacing individual lter bags is possible, but we recommend replacing the whole lter
package, including the lter panel and locking rings, as it is quicker and causes less spreading
of dust.
Individual lter 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 lter bag, but a new locking ring is to be
used to secure the new lter, see Figure 15.
NOTE! Never re-use an old locking ring!
