Adjustment of air damper (in combination with
plastic- and metal foil operation)
It is important that the bearings of the separator are
kept free of foil strips, as the strips will otherwise pack
around the bearings and eventually destroy the separa-
tor. The best way to prevent this, is to provide a con-
stant airflow, that pulls strips that are forced past the
rotor sealing segments, away from the inside of the
separator around the bearings. The separator is there-
fore provided with air intake holes under the bearings,
which ensure an air flow that pulls foil strips in the pipe-
line under the rotor shaft, and back into the material
inlet, whereby the strips will enter the separator again.
To reduce this flow, the opening of the air intake holes
can be adjusted with a sliding damper (see illustration).
The damper is adjusted according to table 1 at the back
of this manual, by loosening the two locknuts and mov-
ing the damper underneath both bearings. The value Y
is measured manually between the slide damper and
the side of the separator.

Electrical installation:
The circuit must be completed by a qualified electri-
cian. He must ensure the installation of overload pro-
tection (the motor must never be connected to power
without it). He must also ensure the installation of a
no-voltage release relay so that the motor can never
restart automatically after a power failure.
In addition to the start/stop function normally incorporat-
ed in a system control panel, a separate lockable start/
stop switch as well as an emergency stop button must
be installed no more than 3 m from each separator.
The first of these will prevent any unintentional start
during service. All local factory inspectorate regulations
must also be complied with.
The separator is supplied with unmounted motor,
as the direction of rotation must be checked before
starting.
When connecting the motor, proceed as follows:
1. The lid of the terminal box is removed and the mo-
2. The power is connected, and the direction of rota-
3. If the direction of rotation is OK, the motor is
4. Refit the terminal box lid
NB! It is very important that the motor is connected with
correct direction of rotation, as the rubber blades other-
wise fold the wrong way. Furthermore, there is a great
risk of deformation of the separator, if the rubber blades
are forced back in correct direction, by simply forcing
the rotor in proper direction of rotation. If the motor is
started in wrong direction of rotation, follow the instruc-
tions later in this section. The motor is therefore not
mounted upon delivery.
General notes regarding connection of 3 phase
asynchronous motors
If the power lines with phase sequences L2, L1 and
L3 are connected to the connection points U1, V1 and
Y
W1 as shown below, the motor rotates anticlockwise,
viewed from the shaft end. The direction of rotation can
be changed by switching between 2 phases.
