Trouble Possible Cause Corrective Action
The suction does not start
even though the electronic
device is connected to the
extraction unit.
• The switch-on threshold for the
automatic operation mode is set too
high�
• Malfunction due to another device
using the same power circuit�
• Re-set the switch-on threshold for the automatic mode
(see chapter 5�5)�
• Connect the extraction unit and the device causing
interference to different power circuits (phases)�
The suction suddenly
stops during automatic
operation, even though the
device connected at the
appliance socket is still in
use. The signal for auto-
matic operation (20, Fig. 2)
is still on.
• Malfunction due to another device
using the same power circuit�
• Connect the extraction unit and the device causing
interference to different power circuits (phases)�
In the automatic operation
mode, the suction starts af-
ter an unusually long delay
time.
• Malfunction due to another device
using the same power circuit�
• Connect the extraction unit and the device causing
interference to different power circuits (phases)�
The suction does not start
after long transportation or
after change of turbine.
• The connection plug behind the
serviceap(13,Fig.1)isnotcom-
pletely inserted�
• Opentheserviceap(13,Fig.1)andpushthecon-
nection plug fully up to the top�
When the unit is switched
on, not all of the displays
light up.
• The display which does not light up
is defect�
• Contact Renfert / Service�
The fuse is released when
a connected electronic
device is switched on.
• The total capacity for the connected
devices is too high�
• Observe the max� connected capacity (see chapter 8)�
The suction process in the
continuous operation or
automatic operation stops
abruptly and the rele-
vant displays are still on
(20 / 22, Fig. 2).
• The suction turbine is overheated�
• The suction turbine is defect�
• Switch the unit off and allow to cool down for at least
60 min�
• Check whether the suction tube is blocked� Eliminate
blockage�
• Switchtheunitoffandthenonagain,sothatthelter
cleaning process can be carried out�
Changethenelter(seechapter6.3)(ifthelter
cleaning function does not improve the suction perfor-
mance)�
• Change the suction turbine�
