The electric power cable (2) coming out from the vacuum
cleaner near the control panel is without plug.
The user must install a 63 Amps plug conforming to EEC
standards.
Connect the plug to a plug with identical amperage and
protected by a network switch.
This vacuum cleaner creates a strong air flow which is drawn
in through the inlet (5) and blows out through the outlet (6).
The vacuum cleaner is supplied with a remote control phase
reverser which enables the vacuum unit to be started in the
correct direction, preventing air and material from coming out
from the dust conteiner even if the phase connection to the
GB
motor does not comply with the correct sequence.
Before turning on the vacuum cleaner, fit the vacuum hose
into the inlet and then fit the required tool on to the end part.
Refer to the manufacturer's accessory catalogue or Service
Centre.
The Mod. "3997W - 3997WC" vacuum cleaner is not
provided with quick-fit coupling of the suction hose,
therefore the hose must be fixed to the Ø120 inlet
hose with a clamp.

Vacuum cleaner description

Figure 1
WARNING!
The diameters of the authorised hoses are given in the
technical specifications table.
This vacuum cleaner is equipped with a circumferential
inlet which subjects the vacuumed substances to a circular
centrifugal movement that makes them drop into the
container.
The vacuum cleaner is equipped with a primary filter which
enables it to be used for the majority of applications.
Different types of class L main filter for dust harmful to health
are available on models "3997 - 3997W"; models "3997C -
3997WC" are equipped with class M filter cartridges.
Besides the main filter which retains the more common types
of dust, the vacuum cleaner can be fitted with a downstream
absolute filter, with a higher filtering capacity for fine dust and
substances harmful for the health.

Optional kits

Various optional kits are available for converting the vacuum
cleaner:
■ lifting bracket
■ downstream absolute filter
■ grill and depressor with bag
■ grid
On request, the vacuum cleaner can be supplied with optional
kits already installed. However, they can also be installed at a
later date.
Please contact the manufacturer's sales network for further
details.
Instructions to install parts on request are included in the
conversion kit.
