Electrical Connection; Adjusting And Displaying The Extraction Force - Renfert Silent 230 Mode D'emploi

1.2 Connection to the
Extraction Point
Use the included suction hose to connect the unit to
the extraction point.
• Push the suction hose onto the extractor connec-
tion fitting on the dust extractor (Figure 1).
• Connect the suction hose to the desired extraction
point (e.g., sandblasting unit, dry trimmer, extractor
clamp, etc.).
Using extractor switches, several extraction points
can be connected to a single dust extractor, if neces-
sary, with the aid of hose fitting adapters (refer to the
accessories list).
Never operate the Silent without a suction
hose.
Avoid steep pitches or hanging points
along the hose path. Never kink the hose
and make sure it is never stretched or
under tension when connected.

1.3 Electrical Connection

Before connecting the unit to the wall
outlet, make sure the voltage information
on the nameplate corresponds to your local
power supply.
• Unroll the power cord.
• Press the OFF switch (Figure 2a) to make sure the
dust extractor is switched off.
• Plug the power cord into the wall outlet (Figure 3).
the Silent is now ready for
continuous operation.
1.4 Connection of Electric,
Dust-Generating
Equipment
When connecting electrically operated
equipment to the dust extractor, please ob-
serve the operating instructions and safety
information provided with the equipment.
the unit power outlet is to be used only for
connecting electric, dust-generating de-
vices to be operated in conjunction with the
dust extractor.
the unit power outlet is live once the Silent
has been connected to the power supply
– even when the Silent is switched off. this
allows connected devices to be operated
without extraction for brief periods.
Power consumption of all devices con-
nected to the unit power outlet may not
exceed the rated value printed next to the
unit power outlet.
The Silent can be operated in either the continuous or
automatic mode.
In the automatic mode, extraction starts automatically
when a connected electric device is switched on.
For this, the dust-generating device is connected to
the unit power outlet on the back of the dust extractor
(Figure 4a).
Section D.2 at the end of these instructions offers
information concerning electrical systems employing
different power plug designs.

2.2 Switching the Unit
ON / OFF
The Silent is switched on at the ON switch (B)
(Figure 2b), and off at the OFF switch (A) (Figure 2a).
Extraction starts and stops in conjunction with the
selected operating mode (continuous operation or
automatic operation).
The operating mode selected when the unit
is switched off is saved if the unit was run-
ning in the selected mode for longer than
approx. 5 sec. When the unit is again swit-
ched on, it automatically starts in the saved
mode.
2.3 Adjusting and Displaying
the Extraction Force
The Silent can be adjusted to provide 9 levels of
varying extraction force. This permits the unit's per-
formance to be precisely matched to different types of
materials being extracted.
The extraction force setting is shown on the display
(G) (displayed values from 1 to 9). The extraction
force can be increased or decreased with the adjust-
ment switches (F) and (H).
Increase the extraction force.
Decrease the extraction force.
