Extensions

If an extension cable is used, make sure it is suitable for the
power input and protection degree of the machine.
Max power (kW) 3
Minimum section (mm2) 2.5
Maximum length (m)
Cable
CAUTION!
ATEX variant: extensions,
devices and adapters cannot be used when vacuuming
flammable dust.
CAUTION!
Sockets, plugs, cable
installation of the extension cable must maintain the IP
protection degree of the machine, as indicated on the
data plate.
CAUTION!
The machine power socket must be protected by a
differential circuit-breaker with surge current limitation,
that shuts off the power supply when the current
discharged to the ground exceeds 30 mA for 30 msec.
or an equivalent protection circuit.
CAUTION!
Never spray water on the machine: this could be
dangerous for persons and could short circuit the
power supply.

Dry applications

[ NOTE ]
The supplied filters and the bag (if applicable) must be
installed correctly.
CAUTION!
Comply with the safety regulations governing the
vacuumed materials.

Vacuuming of liquids

CAUTION!
Comply with the safety regulations governing the
vacuumed materials.
CAUTION!
■ Make sure the liquid stop device is working
correctly before vacuuming liquids.
■
If foam forms, turn off the machine immediately
and empty the container.
■ Warning: switch off the machine immediately if
foam or liquid leaks out.
■
Regularly clean the liquid level limiting device
and check to make sure that there are no signs of
damage.
■ Dirty liquid vacuumed up by the machine must be
considered conductive.
CAUTION!
Do not use the machine if the liquid mechanical stop is
not installed!
If it's used without the float, the machine may be
seriously damaged.
CAUTION!
When vacuuming a mix of water and air, take care to
avoid overloading the motor of the vacuum unit.
The machine vacuums liquids and deposits them into the
container.
When the machine vacuums liquids it must be equipped with
liquid mechanical stop.
The liquid mechanical stop requires a special container with
relevant nozzle.
Before starting the machine, close the inlet on the filtering
chamber with the relevant plug and fit the vacuum hose in the
inlet on the dust container, then fit the required tool on to the
end part of the hose (refer to the manufacturer's accessory
catalogue or Service Centre).
The liquid mechanical stop stops the vacuuming operation (the
vacuuming units remain activated) when the liquid container is
full; it is then necessary to turn off the machine and empty the
liquid container.
The machine does not switch off automatically.
