Cleaning
Use a damp cloth to clean the outside of the unit.
Do not use abrasive or solvent-based cleaning agents.
Empty Dust Drawer
After having reached the previously set time interval a request appears to empty the dust drawer.
♦ An audible signal will be emitted 3 x.
♦ The display dust drawer (24) lights up.
Before removing the dust drawer, a filter cleaning procedure should be carried out.
⇒ Press the enter key (25) for 2 seconds.
♦ The filter cleaning procedure is carried out (duration approx. 8 seconds).
After the filter cleaning has finished:
⇒ Unfasten (4A) the dust drawer.
⇒ Pull the dust drawer forwards (4).
⇒ Remove the holder (14).
⇒ Close the disposal bag, remove and dispose of.
Observe the local waste regulation and accident prevention regulations when disposing of the
product! Wear the appropriate personal protection equipment according to the type of dust.
⇒ Insert a new disposal bag through the holder and fold the ends over the
holder ring.
⇒ Place the disposal bag with the holder into the dust drawer. The holder ring
is fixed in place in the dust drawer with magnets. Ensure that the disposal
bag:
- has contact with the side walls of the dust drawer;
- does not have contact with the seal surface.
⇒ Replace the dust drawer and slide in completely.
⇒ Close the fastening (4A).
⇒ Press the enter key (25) (the time interval counter is re-set).
♦ An audible signal confirms the drawer has been replaced.
♦ The dust drawer display (24) goes off.
If the dust drawer is not emptied, the dust drawer display (24) remains on. After switching the unit
off and on again, a 3 x audible signal indicates that the dust drawer must be emptied.
In case of heavvy materials (for ex. zirconium dust) we recommend to use 2 disposal bags for a
safe removal and a safe transport (bag in bag solution).
To set the time interval, see Fig. E at the start of this manual, or find information in the instructions for use
in the Internet.
Change fine filter
If the filter cleaning does is not sufficient (suction performance does not improve), then the fine filter
needs to be changed.
This is detected by the suction unit and indicated by the error display (26).
If a change of the fine filter is requested or the extraction force does not substantially improve
or only improves for a short time in spite of repeated cleaning, the fine filter must be changed
straight away.
Further operation may cause damage to the unit.
Carry out the automatic filter cleaning process before changing the fine filter.
► In general, the fine filter should be changed every 2 years.
When the new fine filter is inserted, check that it is fitted correctly as otherwise leaks may occur. See the
assembly instruction at the end of the instruction manual, which is also attached to the new fine filter.
