3.1 Starting the machine
The control current outlet (low voltage) should be connected
to a control current lead running the length of the pipes.
Both ends of the low-voltage lead should be connected to
the connection panel on the vacuum cleaner. One lead to
each outlet.
The central vacuum cleaner's power cable must be con-
nected to a 120 volt mains socket. The appliance is double-
insulated and does not need to be grounded.
The vacuum cleaner starts and stops automatically. When
the vacuum hose is connected to a vacuum socket, a metal
ring on the end of the hose closes the control circuit and
the vacuum cleaner starts up. 7. When the hose is removed
from the vacuum socket, the vacuum cleaner stops. You
should allow the hose to empty of dust and dirt before swit-
ching the vacuum cleaner off.

If you use a hose with an on-off switch, you can start
and stop the vacuum cleaner using the switch on the
handle, Fig. 8.

3.2 Servicing
Always unplug the power cord before doing
any service work!
If suction is poor, it indicates that the fl ow of air through the
machine is restricted. This may be due to the following:
• The dust bag is full and should be replaced.
• The fi lter is clogged and should be cleaned.
The vacuum cleaner has a thermal cut-out that trips if the
vacuum cleaner becomes overheated. If this happens - un-
plug 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.
NOTE! The CV 10 cleaner must only be operated with
the dust bag and the fi lter installed.
