A.2 Ambient Conditions
(in accordance with DIN EN 61010-1)
The unit may only be operated:
• Indoors;
• Up to an altitude of 2,000 m above sea level;
• At an ambient temperature range between
5 - 40ºC [41 - 104ºF] *);
• At a maximum relative humidity of 80% at 31ºC
[87.8ºF], dropping in a linear manner to 50% rela-
tive humidity at 40ºC [104ºF] *);
• With mains power where the voltage fluctuations
do not exceed 10% of the nominal value;
• Under contamination level 2 conditions;
• Under over-voltage category II conditions;
*) Between 5 – 30°C [41 – 86°F], the unit can be operated at
a relative humidity of up to 80%. At temperatures between
31 – 40°C [87.8 – 104°F], the humidity must decrease
proportionally in order to ensure operational readiness (e.g., at
35°C [95°F] = 65% humidity; at 40°C [104°F] = 50% humidity).
The unit may not be operated at temperatures above 40°C
[104°F].
B. Hazard and Warning
Information
Only intended for indoor use. the unit is
only designed for dry applications and may
not be operated or stored outdoors or
under wet conditions.
the Silent laboratory dust extractor is an
electric device and, as such, carries with it
a certain inherent potential hazard. the unit
may not be taken into service until any re-
quired alterations to comply with regionally
specific power plug configurations have
been made. Such alterations may only be
performed by a qualified electrician.
the unit may only be operated if the infor-
mation on the nameplate conforms with the
specifications of your local mains power
supply.
Do not extract health-hazardous dusts with
an MAK value of < 0.1 mg/m³.
Please note EN 60335-2-69, Appendix AA,
or initiate appropriate enquiries with your
trade association or the responsible
authorities.
When extracting hazardous materials,
always refer to the relevant safety data
sheets.
Always wear protective gear when extract-
ing hazardous materials.
Regularly inspect connecting lines and
hoses (e.g., the power cord) for damage
(e.g., kinks, cracks, porosity) or signs of
aging.
Units exhibiting damaged connecting lines,
hoses, or other defects must be taken out
of service immediately.
Always unplug the unit from the wall outlet
before beginning any work on the unit's
electrical components.
Never operate the unit without the complete
filtration system (dust bag, fine particle
filter, exhaust air filter, electronics filter).
Make sure the dust drawer is fully closed
during extraction.
Never operate the unit without the suction
hose.
Never extract flammable or explo-
sive gases, vapours, dusts.
Never extract liquids.
Never extract hot materials.
the unit may not be operated without
supervision.
All required tools must be appropriately
cleaned prior to use when the unit is
employed for medical purposes or in con-
junction with medicinal materials.
If the dust extractor is employed to extract
hazardous materials, appropriate personal
protective gear must be worn and steps
must be taken to ensure that the exhaust
air is properly ventilated. Please refer to the
associated safety data sheets for specific
requirements.
c. Authorised Individuals
Only properly trained individuals may operate and
service the Silent.
Minors or pregnant women may only operate and
service the Silent if they are wearing appropriate
protective gear, particularly if the unit is being used to
extract hazardous materials.
Any repairs not specifically described in these operat-
ing instructions, in particular the inspection of the suc-
tion turbine outside the unit, may only be performed
by a qualified electrician.
D. Preparations Prior to
Starting
D.1 Connecting the Dust
Extractor
The unit is supplied with a power cord and two-con-
tact plug with a ground contact (either DIN 49441 or
NEMA, depending on the particular model in ques-
tion).
The unit may not be taken into service until any
required alterations to comply with regionally specific
power plug configurations have been made.
Such alterations may only be performed by a quali-
fied electrician.
The unit may only be connected to wall outlets con-
nected to a ground circuit system.
Before operating the unit, make sure the voltage in-
formation on the nameplate corresponds to your local
power supply.
