Cleaning / Maintenance

The device does not contain any internal parts that require maintenance.
Opening the device other than described in the instructions is not permitted!
6.1 Cleaning
To clean the device wipe only with a damp cloth�
Do not use and solvent-based or abrasive cleaning agents�
6.2 Empty Dust Drawer
After reaching the set time interval (see Chapter 5�5�2), the dust drawer is requested to be emptied:
♦ An acoustic signal sounds 3 x�
♦ Display dust drawer (26, Fig� 2) lights up�
♦ The display (24, Fig. 2) shows a container filling up.
Before removing the dust drawer, a filter cleaning function should
be performed:
⇒ Press Enter key (27, Fig� 2) for 2 seconds�
♦ The filter cleaning function is performed.
♦ The counter for recording the time interval is reset�
After the filter cleaning has finished:
⇒ Unlock the dust drawer with the clamp fastener (4a)�
⇒ Pull the dust drawer (4) forward and empty�
⇒ Replace the dust drawer again until it locks into place�
⇒ Close the clamp fastener (4a)�
If the dust drawer has been emptied without prior filter cleaning,
the counter must be reset separately to record the time interval�
⇒ Press the Enter key (27, Fig� 2) (counter for recording the time
interval is reset)�
♦ Acoustic signal acknowledges the information�
♦ Dust drawer display (26, Fig� 2) is deleted�
If the dust drawer is not emptied, the dust drawer (26, Fig. 2) display will continue to light up. After
switching the device off and on again, a 3 x acoustic signal is used to indicate the emptying of the
dust drawer.
6.3 Change Fine Filter
The effectiveness of the filter cleaning is determined by monitoring the flow rate (internal pressure sen-
sor)�
If a filter cleaning is required several times in succession after less than 2 hours, this means that the fine
filter is so highly clogged that the filter cleaning does not show sufficient effect and the fine filter has to be
changed�
This is indicated as follows:
♦ "F" in display (24, Fig� 2)�
♦ For a period of 15 min�, 2 long beeps are sounded for 3 min at a time�
The error message can be switched off by switching off the suction�
If requested to change the fine filter or the suction performance does not improve substantially
despite repeated cleaning or only for a short period, the fine filter must be changed soon.
Further operation can lead to damage to the device.
When replacing the fine filter, pay attention to the correct fit, otherwise leaks will occur. Please refer to the
assembly instructions at the end of the manual, which are also included with the new fine filer.
