Trouble
Possible Cause
Corrective Action
The suction starts even
though the electronic de-
vice connected to the unit
is not being used.
•
The automatic switch-on function has
been set too low.
•
Malfunction due to another device
using the same power circuit.
•
Setting the automatic switch-on (calibra
-
tion).
•
Connect the extraction unit and the de
-
vice causing interference to different pow
-
er circuits (phases).
The suction does not stop
when the electronic device
is switched off.
•
The automatic switch-on function has
been set too low.
•
Malfunction due to another device
using the same power circuit.
•
Setting the automatic switch-on (calibra
-
tion) (see chapter 5.5).
•
Connect the extraction unit and the de
-
vice causing interference to different pow
-
er circuits (phases).
The suction does not start
even though the electronic
device is connected to the
extraction unit.
•
The automatic switch-on function has
been set too high.
•
Malfunction due to another device
using the same power circuit.
•
Setting the automatic switch-on (calibra
-
tion) (see chapter 5.5).
•
Connect the extraction unit and the de
-
vice causing interference to different pow
-
er 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-
)
is still on.
•
Malfunction due to another device
using the same power circuit.
•
Connect the extraction unit and the de
-
vice causing interference to different pow
-
er 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 de
-
vice causing interference to different pow
-
er circuits (phases).
The suction does not start
after long transportation or
after change of turbine.
•
The connection plug behind the ser
-
) is not completely
inserted.
•
Open the service flap (13,
Fig. 1
) and
push the connection 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
).
•
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.
•
Switch the unit off and then on again, so
that the filter cleaning process can be
carried out.
Change the fine filter (see chapter 6.3)
(if the filter cleaning function does not
improve the suction performance).
•
Change the suction turbine.
