Battery
The lifetime of the enclosed batteries in the bent end is
approximately three (3) years. If the battery capacity is to
low, the cleaner will then be shut off. If the cleaner would not
start or the power regulation via the hose handle does not
work, you must replace the batteries at the hose handle.
Replace to battery type 1.5V AAA. For more information and
trouble shooting see Section 10 in this instruction for use.
How to replace the batteries in the hose handle
1. Open the lid of the battery holder by sliding
the lid towards the front of the hose handle.
2. Replace the used batteries with two
new ones, type 1.5V AAA. Make sure
the polarity of the batteries is placed
correct at the bracket.
3. Slide the battery lid back until you
hear a click.
10 Troubleshooting
The vacuum cleaner will not start
Thermal protector
The vacuum cleaner has a thermal cut-out that trips if the
vacuum cleaner becomes overheated.
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 bag filter,
container/dust bag, suction hose and vacuum socket to
be sure that nothing is blocking the flow of air through the
machine. The vacuum cleaner should now start again. If the
cut-out trips again, you need to get a service firm to remedy
the fault.
On CVR 4000 the symbol for overheating will show in the
display of the vacuum cleaner.
Other troubleshootings
• Are you using the correct hose? Only the original hoses
fit correctly.
• Does the vacuum cleaner start when you try a different
vacuum socket? If so, there is a fault in the electrical
connection to the first 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 wireless hose handle 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?
• Is the dust bag full or clogged?
• Is filter clogged?
CVR 4000 Display
The CVR 4000 model has a display giving information about
the machine, Fig. 19.
All work involving the 240 volt mains
electricity supply must be carried out by a
qualified electrical contractor
!
WARNING!
Do not pull out the suction hose from the
cleaner while the cleaner is still running as
it will cause too little airflow through the
cleaner.
The machine has a safety shut off function
and a thermal protector which will stop the
machine but this will cause an unnecessary
abrasion on the motor
