Changing the pre-filter mat:
1. Carefully remove the pre-filter insert frame (item 5.1) from the filter
section without whirling up dust particles.
2. The clamping bracket that fixes the pre-filter mat in place can now be
removed without difficulty.
3. Carefully, without whirling up dust particles, remove the soiled pre-filter
mat from the pre-filter insertion frame. Fold the pre-filter mat so that
the side covered in dust particles is facing inwards.
4. Place the soiled pre-filter mat in a waste disposal bag and seal it airtight
with a cable tie. Suitable disposal bags are available from the
manufacturer.
5. Now, insert a new pre-filter mat into the pre-filter insertion frame and fix
it again with the clamping bracket.
6. Reinsert the pre-filter insert frame into the product.
Changing the main filter:
1. Slightly lift the main filter (item 5.3) at the front using the grip straps in
order to separate the seal from the supporting surface. Pull it about two
thirds out of the filter housing so that the filter element with the bolt
remains on the side guide profiles.
2. At the rear, the main filter slides on side-mounted bolts on guide
profiles which causes it to be lifted. This means that the seal is not
damaged at the back.
