Information for Operators
Using these operating instructions as a
starting point, instruct all operators of the
unit with regard to the area of application,
the possible hazards during operation, and
the proper operation of the dust extractor.
Please have these operating instructions readily
available for the operators.
Additional information can be found in the Section,
“InformationforOperators”,
at the end of these instructions.
Operating Instructions
1. Setup and
Commissioning
1.1 Setup
Remove the unit and all accessories from the ship-
ping package.
Inspect the delivery for completeness (refer to the
“StandardDelivery”Section).
The unit is fully operational upon delivery.
Select a setup location for the Silent TS
where the exhaust air vent is not blocked.
Where the unit is to be installed in a cabinet, an
opening with the following minimum dimensions must
be provided:
• Circular opening: Diameter at least 120 mm
• Rectangular opening: At least 170 x 65 mm.
The Silent TS is a free-standing unit intended to be
setupontheoor(e.g.,underaworkbench).
Particularly after installation of the roller
set (refer to the accessories list), the dust
extractor may only be operated if it is
standing on the oor.
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-
tionttingonthedustextractor(g.1).
• Connect the suction hose to the desired extraction
point (e.g., Dustex master plus, extractor clamp,
etc.).
With the aid of an extractor switch or a Y-junction it is
possible to connect up to two suction points, or if nec-
essary, use a universal adapter for connector tubes
(seeaccessories).
Never operate the Silent TS without a suc-
tion 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.
Arrange conducting parts (mains outlets, plugs and
couplings)andinstallextensioncordsuchthatthe
protectionclass(IP)isretained.
• Unroll the power cord.
• PresstheOFFswitch(g.2A).
• Plugthepowercordintothewalloutlet(g.3).
The Silent TS is now ready for continuous
operation.
1.4 Connecting electrical
equipment
Electronic equipment (electrical dust-generating
equipment)canbeconnectedtotheSilent TS at the
couplersocketatthebackofthemachine(N,g.4).
In the automatic mode, extraction starts automatically
when a connected electric device is switched on.
Section D.2 at the end of these instructions offers
information concerning electrical systems employing
different power plug designs.
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 devic-
es to be operated in conjunction with the
dust extractor.
The unit power outlet is live once the Silent
TS has been connected to the power supply
– even when the Silent TS is switched off.
This allows connected devices to be operat-
ed without extraction for brief periods.
Power consumption of all devices connect-
ed to the unit power outlet may not exceed
the rated value printed next to the unit pow-
er outlet.

1.5 External Exhaust Air Route
Anexternalexhaustairroute(seeaccessories)al-
lows the extracted air to leave the laboratory.
The installation details are supplied with the external
exhaust air route.
When the extraction unit is used in conjunc-
tion with an external ventilation system, a
signicant quantity of air is extracted from
the room per hour.
This can create negative pressure within
the room which, when using an air depen-
dent naked ame fed by gas, liquid or solid
fuel, can cause poisonous gasses (e.g.
carbon monoxide) to be drawn into the
working area.
It is therefore essential to ensure that the
fresh air supply is sufcient and that the
environmental air pressure is maintained,
this should then be monitored by an autho-
rized specialist (e.g. a certied Gas Service
Engineer).

Silent TS continues to run for approx. 5 sec., then
stops automatically.
2.6 Adjusting the Automatic
Start Feature
In the automatic mode, the Silent TS is switched on
and off by an automatic start system.
This automatic start feature reacts to the current con-
sumed by an electronic equipment plugged into the
unitpoweroutlet(N,g.4).
If the current exceeds the activation threshold set at
the Silent TS, extraction starts. If the current drops
below this activation threshold, extraction stops.
The factory set parameter for the start-up
threshold enables the Silent TS to react cor-
rectly for most electrical dental equiment.
Should this not be the case for a particular
piece of equipment (eg. a handpiece), then
the start-up threshold can be adjusted ac-
cordingly.
To change the activation threshold:
1. Switch Silent TS on.
2. Press and hold for 3 sec.;
- LED and ash.
- A“0”ashesonthedisplay.

Information for Operators
The following information is intended to assist you,
the operator, in safely working with the Silent TS in
your laboratory.
Using these operating instructions as a
starting point, instruct all operators of the
unit with regard to the area of application,
the possible hazards during operation, and
the proper operation of the dust extractor.
Please have these operating instructions readily
available for the operators.
A.Application Area
The Silent TS is a workbench extractor used to ex-
tract dusts such as occur in laboratories, e.g., dental
labs.
It is solely intended for commercial use in laboratories
and not for private, household use.
The Silent TS can be operated both manually as well
as in conjunction with connected, electric, dust-gener-
ating equipment.
It is possible to connect one or two suction points
to the extractor. The second suction point can be
connected with a Y-adapter which is available as an
accessory(seechapter„accessories“).
In order to protect the health of persons
working in a dental laboratory, the law re-
quires that specialised dust extractors must
be used.
National regulations state the MAK value
- maximum concentration of suspended
particles in the air.
Find out about the legal national threshold
value and the type of dust generated in
your laboratory.
A.1 Proper Use
Proper use implies the extraction of dry, non-explo-
sivedusts.Fire-promoting,easilyammable,amma-
ble, or explosive materials may not be extracted with
the Silent TS.
The extraction of liquids, smouldering, or burning
materials is prohibited.
Anyotheruseisnot„asintended“.Themanufacturer
shall not be liable for any damages resulting from any
such other use.
