A. Application Area
The Silent is a workbench extractor used to extract
dusts such as occur in laboratories, e.g., dental labs
(e.g., as generated by dry trimmers or on dust boxes).
The employed filter system shows a precipitation ef-
ficiency of 99.9%. This corresponds to dust category
"M" (according to DIN EN 60335-2-69).
Possible cause
• Dust extractor not switched on.
• Dust-generating device not
plugged into the unit power outlet
on the Silent.
• Wrong operating mode selected.
• Automatic start feature's threshold
value too high.
• Device fuse has blown.
• Automatic start feature fails to
detect the attached device's
operation.
• Automatic start feature's threshold
value too low.
• Dust-generating device not
plugged into the unit power outlet
on the Silent.
• Wrong operating mode selected.
• Activation threshold too low.
• Some older handheld instruments
do not generate a sufficiently
strong signal for the automatic
start feature.
• Activation sensitivity too low.
• Lock bolts dirty.
corrective action
• Switch the dust extractor on (Sec. 2.2).
• Connect the dust-generating device to the Silent
(Sec. 1.4).
• Select the automatic mode (Sec. 2.5).
• Adjust the automatic start feature (Sec. 2.6).
• Check the fuse, replace as required.(Sec. 3.4)
• Some older handheld instruments do not generate
a sufficiently strong signal for the automatic start
feature. Switch the dust extractor to the continuous
mode.
• Adjust the automatic start feature (Sec. 2.6).
• Connect the dust-generating device to the Silent
(Sec. 1.4).
• Select the automatic mode (Sec. 2.5).
• Adjust the automatic start feature (Sec. 2.6).
• Switch the dust extractor to the continuous mode.
• Adjust the automatic start feature (Sec. 2.6).
• Clean the lock bolts and lubricate them slightly, if
required.
It is solely intended for commercial use in laboratories
and not for private, household use.
The Silent can be operated both manually as well as
in conjunction with connected, electric, dust-generat-
ing equipment.
One or more extraction points can be connected to
the dust extractor. Suction switches – available as
accessory equipment (refer to the "Accessories" Sec-
tion) – are employed to connect multiple extraction
points.
A.1 Proper Use
Proper use implies the extraction of dry, non-explo-
sive dusts.
Fire-promoting, easily flammable, flammable, or
explosive materials may not be extracted with the
Silent.
The extraction of liquids, smouldering, or burning
materials is prohibited.
