5.2 Suction Performance
The suction performance can be set at four different
levels. The current suction level is shown in the
display (38). To see the allocation of the suction level
to the suction channels, see section 5.4.1 Single Use
and section 5.4.2 Multi Use.
Setting the suction level:
• Key (48), to select higher suction level
• Key (46), to select lower suction level
The suction performance of a particular suction level
is automatically adjusted i.e. when a suction channel
is either closed or switched off and according to the
degree of dust in the filter.
The suction performance depends on the degree of dust in the filter, the selected suction level
and the number of open suction channels. If the extraction unit is running at its maximum level, it
may occur that one particular suction point does not achieve its full potential.
In this case, in order to increase the suction level at this particular suction point, it is necessary to
close one or more other suction channels.
5.3 Turbo Level
The suction channels’ efficiency can be increased to
an additional turbo level.
In this case the extraction unit runs at its maximum
performance.
The selected turbo level is shown with a fifth bar (39)
at the suction level display.
Switch turbo level on:
⇒ Press turbo key (49).
Switch turbo level off:
⇒ Press turbo key (49) again
♦ the previously used suction level will automatically
be resumed
or
⇒ press key (46)
♦ Ssuction level four will be set.
it is NOT possible to select the turbo level on a suction tube which has the favorite status (see
section 5.4.5).
5.4 Operation
It is only possible to change from single to multi use mode if all suction channels are closed! For
this reason, close the suction on all suction channels before changing.
5.4.1 Single Use
When in single use, the suction takes place at only suction point.
