Operating instructions Supreme 150 / Supreme 250 / Supreme LCD
6.1 Starting the machine
The control current outlet (low voltage) is 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 unit. One lead to each
outlet.
The central vacuum cleaner’s power cable must be
connected to a 120 volt mains socket. The appliance is
double-insulated and does not need to be earthed.
Start/stop button
All models have a start/stop button on the front to start
and stop the power unit, Fig. 19. The start/stop button can
also be used when/if you want to use a Nilfi sk utility inlet
to vacuum direct from the machine (if you do not have a
Nilfi sk hose with remote control) or for testing and demos.
Manual 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. 20. When the hose
is removed from the vacuum socket, the vacuum cleaner
stops.
5.4 Utility
inlet
If you need an extra inlet on the machine, you can attach
the utility inlet directly to the inlet on the vacuum cleaner
and attach the fl exible hose to the utility inlet.
The utility inlet can be used with both Manual, On/off and
Wireless hoses. Just connect the vacuum hose to the inlet
and push the on/off button on the cleaner to start vacuum
cleaning.
If the lid is not fully closed when detaching the hose, it will
automatically close next time the cleaner is started.
On/Off hose
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. 21
Wireless handle
If you use a hose with a wireless handle, you can start and
stop the vacuum cleaner using the switch on the handle,
Fig. 22. Wireless handles have also the feature of adjusting
the suction power of the cleaner, using buttons at the hose
handle.
6.2 Servicing
Always unplug the power cable 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 of dust.
Thermal protector
The vacuum cleaner has a thermal cut-out that trips if the
vacuum cleaner becomes overheated.
