5.2 Operation
After switching on, the suction unit is in standby mode�
If a suction channel is activated, the suction turbine switches on with the last set suction power level and
the associated pinch valve is opened�
If the second suction channel is then activated, the second pinch valve opens�
The opening / closing of the suction channels takes place:
• Automatically:
An electrical appliance connected to a device socket (8A / 8B, Fig� 1) is
switched on / off�
• Manually:
By pressing a suction channel key (29)�
The letters of the opened suction channels (28) are shown in the display�
If a connected device is switched on, the corresponding suction channel can NOT be closed manually
with the suction channel key, but only by switching off the electrical device�
If the suction to a connected electrical appliance does not react as required (e.g. does not acti-
vate, even though a connected device is in operation) then the switch-on threshold for automatic
operation has to be adjusted (see chapter 5.4.3).
5.2.1 Suction Power
The suction power for the suction unit can be set in 3 levels�
The current level is shown in the display (27)�
Change the suction power:
⇒ Press the [-] key (31)
♦ Reduce suction
⇒ Press the [+] key (33)
♦ Increase suction
The suction always starts with the last used suction level�
Adjustment of suction power:
The set suction level applies to all suction channels� Therefore, the power of the suction turbine is auto-
matically readjusted when a further suction channel is opened or closed, in order to reach the adjusted
suction power at the opened suction channels�
To disable the adjustment of the suction power:
In standby mode:
⇒ Press the [+] / [-] keys (33 / 31) at the same time for a duration of 3 sec�
♦ By pressing the [-] key (31), the display shows “OFF”�
The deactivated adjustment of the suction power is permanently indicated by the
“OFF” indicator above the [-] key (31)�
To activate the adjustment of suction power:
In standby mode:
⇒ Press the [+] / [-] keys (33 / 31) at the same time for 3 sec�
♦ The display will delete “OFF” in the display field above the [-] key (31).
If the suction performance is deactivated, the suction power at a suction channel can drop notice-
ably when the second suction channel is activated.
When suction level “3” and both suction channels are opened, only a reduced suction capacity is
available at the suction channels, since the performance of the suction turbine cannot be further
increased.
5.3 Filter Cleaning
In order to ensure maximum suction performance, the suction unit has a device for cleaning the fine filter
unit� The cleaning takes approx� 8 sec�
The cleaning is carried out:
• Automatically:
-After the unit is switched on;
- With insufficient suction power (flow velocity falls below an internal limit value);
-If the unit has been operated for more than 8 hours (turbine running time) without switching it off;
• Manually, e�g� before removing the dust drawer to empty it (see chapter 6�2)�
