Fig. 6
Fig. 3 Fig. 4 Fig. 5
The machine is connected with the suction pipe in the uppermost position and the exhaust pipe in the lower position.
This connection should not be glued but can be taped when the unit is serviced at a later date. The suction pipe socket can be
fitted to two different points depending on the direction in which you would like to install
the pipe system.
To relocate the suction pipe socket, you need to do the following:
1. Release the suction pipe socket by unscrewing the four combination Torx screws with a
Torx T20 or an ordinary screwdriver, Fig. 3.
2. Pull the socket out of the machine, see Fig. 4.
3. Loosen the plug blanking off the outlet to which you intend moving the suction pipe
socket. Unscrew the four combination Torx screws. Remove the blanking plug from the
machine.
4. Adapt (move) the suction pipe socket to the new outlet. NB! The socket is marked
”Up”.
Make sure the socket is fitted with ”Up” uppermost. Fasten the socket by fitting and tightening the four screws, Fig. 5.
5. Fit the blanking plug to the outlet previously occupied by the suction pipe socket. Use the four screws to hold it in place. The
exhaust pipe must be firmly attached to the wall to ensure its connection with the socket does not loosen. Remember that
you will need to be able to turn the bent pipe in different directions to ensure a suitable pipe layout. Then connect up the
exhaust pipe and muffler, Fig 6. Fit the central vacuum cleaner so that the exhaust pipe is as short as possible, max. 5 metres.
Take the surroundings into consideration when positioning the exhaust. For this reason, you should always fit a muffler.
For additional information concerning the assembly and installation of the pipe system and low-current lead, if
any, please refer to the separate assembly instructions supplied with the pipe package.
2.1 Fitting the wall bracket
2.3 Connecting the machine
Position the holder so that there is plenty of space above
and below the place where the vacuum unit is to be located.
Make sure there is a minimum of 500 mm free space above
the container. Mark the positions for the four screw holes
with a pen or similar. Then select appropriate screws and,
if necessary, wall plugs for the type of wall surface to which
the bracket is to be attached. Drill the four holes for the
wall bracket. The diameter of the screw holes in the holder
is 5 mm. Fit the wall bracket with the large opening pointing
upwards, see Fig. 1. Tighten the screws so that the holder is

The machine is controlled wirelessly from the hose handle of
the vacuum cleaner. In this case you do not have to mount
a low voltage cable between the vacuum socket and the
machine.
On/off hose
Handle on hose with on/off button starting and stopping the
vacuum cleaner.
Manual hose
The vacuum cleaner starts and stops automatically when the
vacuum hose is connected to a vacuum socket. The metal
ring on the end of the hose closes the control circuit and the
vacuum cleaner starts up. When the hose is removed from
the vacuum socket, the vacuum cleaner stops.
Dustpan by the floor
Dustpan for mounting in a plinth under a cabinet will start and
stop the vacuum cleaner when opened and closed.
3.2 Servicing
If suction is poor, it indicates that the flow of air through the
machine is restricted. This may be due to the following:
•The dust bag is full and should be replaced.
•The filter is clogged and should be cleaned.
Thermal cutout
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. The vacuum cleaner should now start again. If the
cut-out trips again, you need to get a service firm to remedy
the fault.

Indicator for dust bag/bag filter
When the dust bag/filter symbol starts flashing
during operation, the cleaner tells you that it is
almost time to clean the bag filter and replace the dust bag/
empty the container. When it is time to do so, symbol will be
lit continuously. The dust bag/filter symbol will be lightened
after every 20 operation hours of the cleaner at the latest.
Reduced airflow indicator - lit
The reduced airflow symbol on the display indicates
that the airflow through the vacuum cleaner is
reduced. After 30 seconds of operation with reduced airflow,
the vacuum motor will be shot down in order to prevent
damage to the motor. If the reduced airflow symbol is lit and
the motor has been shot down, do like this: Check the bag
filter and dust bag (see Sections 7.1, 7.2, 7.3 and 7.4) to see
if anything is blocking the airflow. Also check that nothing is
blocking suction hose and/or vacuum sockets. Remove the
material causing the reduced airflow symbol to indicate.
Service indicator
When the service symbol starts flashing, 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 allowed amount of run time
has passed. You must now contact an authorised service
workshop and let them perform a service of the cleaner and to
reset the run time counter.

9 Wireless communication - LED/LCD
9.1 Transmitter/receiver
Before you mount the transceiver box to the wall you should
always test if you have a signal between the transceiver box
and the hose handle in your entire home. Connect the box to
the cleaner and turn the cleaner on and off using the hose
handle from different places in your home.
Connecting the transmitter/receiver
To be able to use the wireless Flexit hose
handles, you must first connect the
transmitter/receiver to the cleaner. This is
done by using the 2 meter network cable
(RJ45) that comes with the transmitter/
receiver. Connect the cable to the
transmitter/receiver and the right socket in
the back of the cleaner.
Installing the transmitter/receiver
Mount the transmitter/receiver on the wall minimum 1
meter (if possible) away from the cleaner for best signal
between the transmitter/receiver and the hose handle. The
transmitter/receiver can be moved to different places in
your home for a better range by using an up to 30 meter
network cable. Cables can often be bought in your local
Electronics store.
The first transmission
The hose handle and the cleaner needs to have a first
communication before starting the cleaner. This is also valid
if the hose handle has been replaced (spare part) or if you
want to connect an extra hose. Do like this before starting
your wireless cleaner:
1. Unplug the main cord.
2. Plug in the cord again, and then push the on/off button at
the hose handle for approximately 10 seconds. This must
be done within 60 seconds after the cleaner has been
plugged in
3. The handle and the cleaner do now communicate.
9.2 Wireless hose handle
Instructions for use
The on-off function and power regulation is controlled by
radio technology.
Start and stop

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

Dust
container
Should be emptied
before the container is
3/4 full, depending on
use but normally 2-4
times a year.
Poor suction and
danger of creating
a blockage in the
pipe system.
Release the two handles clamping the dust container. The handles
are easily unlocked by lifting up the handles until they come to a
stop. When you pull the handles outwards away from the cleaner,
the container is released. Lift off the container. Lift out dust bag
and. Empty the container in a plastic bag and put in dustbin. Any
remaining dust or fluff can be removed manually.
Dust bag Should be replaced
before it becomes
completely full,
depending on use but
normally 2-4 times a
year.
Poor suction and

Filter Release the two handles clamping the dust container. The handles
are easily unlocked by lifting up the handles until they come to a
stop. When you pull the handles outwards away from the cleaner,
the container is released. Lift off the container. Do not remove the
filter from the container. Instead, give the filter a light shaking inside
the container to loosen dust from the filter and allow it to fall into
the container. Lift out the bag filter. If a dust bag is being used -
remove it. Then empty the dust from the container in a plastic bag
and put in dustbin.
Should be replaced
before it becomes
completely full,

normally 2-4 times a
year.
Poor suction and
danger of creating a
blockage in the pipe
system.
Dust bag Grasp the edge of the lid and open it by pulling upwards. Remove
the old dust bag by turning the cardboard stiffener to the right or
left so that the elevation on the nozzle penetrates the opening in
the cardboard. Now slide the bag off the inlet. Push the opening in
the cardboard over the elevation on the inlet and pull on the new
bag. Twist the cardboard to lock the bag in place. NB! The opening
in the card must be adjusted and pushed past the elevation on the
inlet before the cardboard can be locked into place with a twisting
action. Note: Never vacuum without a dust bag installed.
Filter in
bottom
Should be checked when
changing the bag.
Poor suction can
result. Dust can find
its way into
the motor.
10.1 Service/maintenance - CVR 1000
Remove the dust bag as described above. Remove the filter from
the bottom. The filter can be cleaned by shaking it or washing it in
water. NB! The filter must be completely dry before being reinstalled.
Replace the cleaned filter in the machine. Press the outer edge of
the filter down against the sides of the container so that the filter
bulges up slightly. Refit the dust bag and replace the lid. Check that
the lid is sitting firmly in place. Note: Never vacuum without a filter
installed.
