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 connected
to a 230 volt mains socket. The appliance is double-insulated
and does not need to be earthed.
Standard hose
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. Fig. 7. When the hose is removed from the
vacuum socket, the vacuum cleaner stops.
On/Off hose
Some models have an hose with remote control (on/off function)
for the vacuum cleaner. The hose for these models are to be
connected as shown in Fig. 7 above. NOTE! The plate at the
hose inlet must be turn upwards, so that the hose inlet will be
locked to the wall inlet by the two notches at the wall inlet.
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 - 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.
The model Bronze/Sopra 100 should only be operated with
a dust bag and fi lter installed.
