The central vacuum cleaner must be connect<strong>ed</strong><br />

to a 220- 240 V mains socket. The machine starts<br />

and stops automatically. When the vacuum hose<br />

is connect<strong>ed</strong> to a vacuum socket a metal ring on<br />

the end of the hose closes the control circuit and<br />

the vacuum cleaner starts up. When the hose is<br />

remov<strong>ed</strong> from the socket the vacuum cleaner<br />

stops. You should allow the hose to empty of dust<br />

and dirt before switching the vacuum cleaner off.<br />

If you use a hose with remote control you<br />

can start and stop the vacuum<br />

cleaner using the switch<br />

on the handle.<br />

Servicing<br />

Always unplug the central unit before doing any service<br />

work! If suction is poor it indicates that the flow of<br />

air through the machine is restrict<strong>ed</strong>. This may be<br />

due to the following:<br />

The dust bag is full or clogg<strong>ed</strong> and should be<br />

replac<strong>ed</strong>.<br />

The filter is clogg<strong>ed</strong> and should be clean<strong>ed</strong> or<br />

replac<strong>ed</strong>.<br />

The pipe system is block<strong>ed</strong> by dust or some<br />

other object.<br />

If suction is poor: Check and rem<strong>ed</strong>y this imm<strong>ed</strong>iately,<br />

otherwise the motor may be damag<strong>ed</strong>.<br />

You may ne<strong>ed</strong> to replace the dust bag even if it is not<br />

full, as it could be clogg<strong>ed</strong> by fine dust. Always try<br />

cleaning the filter before you replace the dust bag. If<br />

cleaning or replacing the air filter and replacing the<br />

bag do not help, then check and, if necessary, clean<br />

the pipe system. Allways clear blockage before<br />

calling a service engineer.<br />

Vacuum valve<br />

In order to protect the motor the machines are fitt<strong>ed</strong><br />

with a vacuum valve. This valve is locat<strong>ed</strong> just below<br />

the exhaust outlet. When the air flow drops below the<br />

set level, for example if the nozzle becomes block<strong>ed</strong>,<br />

the valve opens to let in more air.<br />

NOTE! The vacuum valve must not be block<strong>ed</strong>.<br />
