Maintenance
Carbon Dust Filter (Patent pending)
We recommend that you change this lter
once for every three maintenances of the dirt
receptacle (see page 26). For the DL300,
the integrated monitor will indicate when
to change this lter. These indications are
provided by an electronic timing board, only as
a reference guide.
To do so:
1. Unlatch the opening on the carbon lter
case and gently ip it upward (fi gure 22).
2. Remove the used lter, and discard
(fi gure 23).
3. Insert the new lter. When doing so, please
ensure that the arrow printed on the lter
itself points outwards (fi gure 24).
4. Close casing opening, and latch.
