5.5.3 Enforced cleaning
If it is not possible for the extraction unit to carry out the cleaning process during a work break, (see sec-
tion 5.5.2) an enforced cleaning procedure will take place as soon as the suction performance falls below
a fixed set value.
Enforced cleaning:
♦ The error “Err01” is shown in the display.
♦ An acoustic signal is sent 3 x.
♦ All suction channels are closed.
♦ The automatic cleaning process takes place.
♦ Suction channels which were previously open before cleaning, are then reopened.
5.6 Programming
The menu function enables various extractor settings to be preset and saved.
In order to set different parameter, press the menu key (30) repeatedly.
To confirm and save the adjusted settings press the enter button (45). An audible signal confirms that the
settings have been successfully saved.
If you do not wish to save the adjustments, press the menu key again (30) and the programming will be
aborted.
If the word “default” is shown in the display (47) press the buttons and (46, 48) together to revert to
the standard factory settings (see table in section 6.4).
5.6.1 Self Diagnosis
The diagnosis symbol (31) shows whether the self diagnosis has been activated or not:
When activated, the extraction unit carries out a self diagnosis immediately after having been switched
on.
The suction turbine is switched on and each suction channel is opened individually in order to remove
possible deposits from the suction tubes.
This process takes approximately 30 seconds.
If a fault is discovered during the self diagnosis, then this will be signalized with an error code (see sec-
tion 7.1). Please continue as described in section 7.1.
⇒ Press menu key (30) 1 x.
♦ The diagnosis symbol (31) blinks.
⇒ Switch the self diagnosis ON or OFF using the / buttons (46, 48).
⇒ Press the enter button (45).
