INSTALLATION, USE AND MAINTENANCE MANUAL
7. MOST FREQUENT PROBLEMS
7.1 The main vacuum unit does not work…
• Check the 20 V power supply.
• Check that the low-voltage command is correctly connected to the black and red poles of the main unit,
in case of electrical connections to the sockets.
• Short-circuit the wires of the low-voltage command (black and red). If the main unit starts to operate,
all connections of the suction inlets must be checked.
• The overheating cut-out breaker has tripped. Wait for the motor to cool down to normal operating
temperature (about 2–0 minutes) and trace the cause of overheating (e.g. clogged filter, full dust
container, partial obstruction of a brush or flexible hose, etc).
IF THE MAIN VACUUM UNIT STILL OPERATES INCORRECTLY:
CONTACT THE AUTHORIZED ASSISTANCE SERVICE OR YOUR DEALER, INDICATING THE
SERIAL NUMBER AND MODEL OF YOUR SYSTEM.
7.2 Suction power is very low…
Check that…
• The other suction points are closed
• There are no foreign bodies trapped in the brush, flexible hose or curved joint
• The dust container is correctly installed and is not full
• The filter cartridge is correctly positioned and is clean
• The main vacuum unit is correctly connected to the suction pipe
• The suction pipe is blocked or has no leaks
IF THE MAIN VACUUM UNIT STILL OPERATES INCORRECTLY:
CONTACT THE AUTHORIZED ASSISTANCE SERVICE OR YOUR DEALER, INDICATING THE
SERIAL NUMBER AND MODEL OF YOUR SYSTEM.
