All work involving the 240 volt mains electricity
supply must be carried out by a qualifi ed electrical
contractor with full knowledge of the relevant safety
regulations.
The vacuum cleaner will not start
Thermal protector
The vacuum cleaner has a thermal cut-out that trips if the
vacuum cleaner becomes overheated.

Supreme 250 / Performer 250
If this happens - unplug the main power cord to reset the
vacuum cleaner. Wait 5-10 minutes to allow the machine to
cool down. While you are waiting, check the hose, dust bag
and fi lter to be sure that nothing is blocking the fl ow of air
through the machine. The vacuum cleaner should now start
again. If the cut-out trips again, you need to get a service
fi rm to remedy the fault.

When the overheat symbol in the display on the cleaner is
activated (models with display) the cleaners' thermal cut-out
has tripped. For more information regarding thermal cut out,
see Overheat indicator.
Other troubleshootings
• Are you using the correct hose?
Only the original hoses fi t correctly.
• Does the vacuum cleaner start when you try a different
vacuum socket? If so, there is a fault in the electrical con-
nection to the fi rst socket. Unscrew the socket and check
the connection at the back.
• Is the power supply connected to the vacuum unit?
• Is there power at the socket?
• Is the low-voltage lead connected to the vacuum unit?
• The batteries to the radio remote control (wireless version
of vacuum cleaner) may have been discharged. Replace
the batteries with new ones, type 1.5V AAA.
The vacuum cleaner will not stop
• Has a metal object become lodged in one of the vacuum
sockets causing the pins to become fused?
Poor suction power
• Are all the vacuum sockets closed properly?
• Has something become jammed in one of the vacuum
sockets?
• Is the container lid closed properly?
• Is the gasket between the container and the lid in place?
• Is it damaged?
• Is the pipe system blocked?

Supreme LCD Display

Speed level
When the start button is pushed or the hose is connected to
the wall socket, the display will turn on and show the speed
level.
Dust bag/bag fi lter indicator
When the dust bag/fi lter symbol starts to fl ash during opera-
tion, the cleaner tells you that it is almost time to clean the
bag fi lter and replace the dustbag. When it is time to do so,
symbol will be lit continuously. The dust bag/fi ler symbol will
be lightened after every 20 operation hours of the cleaner. If
the symbol is lit, do like this: Turn off the cleaner by the hose
handle (remote versions) or remove the suction hose from
the wall inlet or by pushing the on/off switch on the display.
Then check if the bag fi lter/dustbag is clogged. Replacement
is described in chapters
7.1, 7.2, 7.3 and 7.4.
Reduced airfl ow indicator - lit
The reduced airfl ow symbol on the display indicates that
the airfl ow through the vacuum cleaner is reduced. After 30
seconds of operation with reduced airfl ow, the vacuum motor
will be shot down in order to prevent damage to the motor. If
the reduced airfl ow symbol is lit and the motor has been shut
down, do like this: Check the bag fi lter and dust bag (see
chapters
7.1, 7.2, 7.3 and 7.4)
the airfl ow. Remove the material causing the reduced air fl ow
symbol to indicate.
Service indicator
When the service symbol starts fl ashing, the motor will run
for one more hour before it stops/will not start. The purpose
of the service symbol is to inform you that it is time to order
service of the cleaner. When the symbol is continuously lit,
the run time counter in the cleaner has counted that the al-
lowed amount of run time has passed. You must now contact
an authorised service workshop and let them perform a ser-
vice of the cleaner and to reset the run time counter.
Overheat indicator - fl ashing
The overheat symbol indicates that the cleaner has become
overheated. The cleaner stops automatically. Unplug the
main power cored to reset the vacuum cleaner and wait 5-10
minutes to allow the machine to cool down. While you are
waiting, check the hose, dust bag and fi lter to be sure that
nothing is blocking the fl ow of air through the machine.
Signal indicator - fl ashing
When the symbol is fl ashing, the hose handle is out of range
and there is no connection to the cleaner. The cleaner will
automatically stop after 30 min. if the hose handle or the
cleaner has not been activated.
