INSTALLATION, USE AND MAINTENANCE MANUAL
5.1 Protection fuse
All main vacuum units are protected by a fuse that interrupts the power supply to the motor in case of
malfunctions or electrical problems.
To replace the fuse, unscrew the fuse-holder located above the power supply cable (see diagram on page
– item 2).
NB: the fuse replacement is an operation that only a service centre can perform. The service centre will
replace it with a short-burn fuse. Consult the chart in section 1. for technical characteristics.
5.2 Cut-out breaker against overheating
All main vacuum units are fitted with a thermal cut-out breaker that stops the motor in case of
overheating.
In case of unit stop due to thermal cut-out breaker, allow the motor to cool down to normal operating
temperature (about 2-0 minutes). Then trace the cause of overheating (e.g. clogged filter, full dust
container, partial obstruction of a brush or flexible hose, etc).
5. SAFETY COMPONENTS
The motor unit that drives the turbine and all other electrical components must
be opened only by a specialized technician or by an authorized service centre.
CAUTION: The main vacuum unit can suffer damages if restarted without
having removed or eliminated the cause for overheating.
