Quality standards
and safety
Products from are subject to
stringent quality testing with regard to safety and operation.
Each product undergoes a comprehensive test program prior to
delivery.
Observe the instructions for all actions as specified in this man-
ual.
No special protective clothing is required to operate the vacuum
pump. Observe instructions issued by the operator for your
workplace.
During cleaning, maintenance and repair work, we recommend
wearing chemical-resistant protective gloves, protective clothing
and protective goggles.
ðWhen handling chemicals, wear your personal protective
equipment.
Safety precautions ðUse your vacuum equipment only if you have understood its
function and this manual.
ðReplace defective parts immediately, e.g., a broken power
cord, faulty hoses or faulty flasks.
ðUse only original accessories and components which are
designed for the vacuum technology, such as a vacuum
hose, separator, vacuum valve, etc.
ðWhen handling contaminated parts, follow the relevant reg-
ulations and protective measures; this also applies to equip-
ment sent in for repair.
Prior to returning any product to our Service Depart-
ment for repair, contamination from hazardous substances
needs to be excluded. Therefore, send us the carefully com-
pleted and signed Health and Safety Clearance certificate be-
fore sending your product for repair.
Safety information
20901118_EN-US_PC301x VARIO select Serie_V1.3_100720 17
During aspiration, hazardous, toxic substances at the
outlet can get into the ambient air.
ØObserve the relevant safety regulations for safe han-
dling of hazardous substances.
ØPlease note that residual process media may pose a
danger to people and the environment.
ØInstall and use suitable separators, filters or extrac-
tion devices.
Pumping different
substances
Pumping different substances or media can cause the sub-
stances to react with one another.
Working materials which get into the vacuum pump with the gas
flow can damage the vacuum pump. Hazardous substances can
be deposited in the vacuum pump.
Protective mea-
sures, depending
on application
ðPurge the vacuum pump with inert gas or air before chang-
ing the medium to be pumped.
ðUse inert gas to dilute critical mixtures.
ðPrevent the release of hazardous, toxic, explosive, corro-
sive fluids, gases or vapors or those that are harmful to
health or the environment, for example, through suitable
laboratory facilities with a fume hood and ventilation control.
ðProtect the inside of the vacuum pump from deposits or
moisture, e. g, through the provision of a gas ballast.
ðBe aware of interactions and possible chemical reactions of
the pumped media.
ðCheck the compatibility of the pumped substances with the
wetted materials of the pumping unit.
ðContact us if you have concerns about using your vacuum
pump with certain working materials or media.
Safety information
18 20901118_EN-US_PC301x VARIO select Serie_V1.3_100720
Observe vacuum
pump design
Particles, liquids and dust must not get inside the vacuum pump.
ðDo not pump any substances which could form deposits in-
side the vacuum pump.
ðInstall suitable separators and/or filters upstream of the in-
let. Suitable filters are chemical-resistant, clog-proof and
have a reliable flow rate, forexample.
ðReplace porous vacuum hoses without delay.
Note mechanical
load capacity
The high compression ratio of the pump may result in a higher
pressure at the outlet than the mechanical stability of the system
allows.
ðAlways ensure that the outlet line is clear and non-pressur-
ized. The outlet must not be blocked to ensure that gases
can exit freely.
ðPrevent uncontrolled overpressure, e. g, due to a locked or
blocked piping system, condensate or clogged outlet line.
ðAt the gas connections, the connections for the inlet IN and
outlet EX must not be mixed up.
ðBe aware of the max.pressures at the inlet and outlet of the
pump as well as the max. admissible differential pressure
between the inlet and outlet, according to the technical
data.
ðThe system to be evacuated as well as all hose connections
must be mechanically stable.
ðFix coolant hoses to the hose nozzles such that they cannot
inadvertently become loose.
Prevent backup in
the outlet line
Condensate can damage the pump head. Condensate must not
flow back into the outlet and pump head through the hose line.
Liquid must not accumulate inside the exhaust gas hose.
ðAvoid condensate return by using a separator. Condensate
must not enter the inside of the housing via the hose lines.
ðPreferably route the exhaust gas hose with a fall from the
outlet, i.e.,running downward so that no backup can form.
Safety information
20901118_EN-US_PC301x VARIO select Serie_V1.3_100720 19
ðIncorrect measurements due to a blocked vacuum line, e.g.,
condensate in the vacuum line, can distort the measure-
ments taken by the vacuum sensor.
ðAvoid overpressure in the suction line (>/1060mbar
[>/795Torr]).
Observe hazards
during venting
Depending on the application, explosive mixtures can form or
other hazardous situations can arise in systems.
Possible residual
energy
After the vacuum pump has been switched off and disconnected
from the power supply, there may still be dangers due to resid-
ual energy:
nThermal energy: motor waste heat, hot surface, compres-
sion heat.
nElectrical energy: the installed capacitors have a discharge
time of up to 3minutes.
Before any action:
ðAllow the vacuum pump to cool down.
ðWait until the capacitors have discharged.
Surface tempera-
tures
The surface of vacuum pumps can reach temperatures >70°C
during operation, in particular when pumping out heated media.
ðAvoid direct contact with the surface.
ðUse protection against accidental contact if the surface tem-
perature is regularly elevated.
ðAllow the vacuum pump to cool down before performing
maintenance work.
Overheating The vacuum pump can be damaged due to overheating. Possi-
ble causes include insufficient air supply to the fan and/or failure
to maintain minimum distances.
ðWhen installing the device, ensure that there is a minimum
distance of 5cm between the fan and adjacent parts (such
as the housing, walls, etc.).
ðAlways ensure a sufficient air supply; if applicable, provide
external forced ventilation.
Safety information
20 20901118_EN-US_PC301x VARIO select Serie_V1.3_100720
ðPlace the device on a stable surface. A soft surface such as
a foam rubber sound absorber can impair and block the air
supply.
ðClean polluted ventilation slots.
ðRemove the cover used as transport protection from the de-
vice before operating it.
ðAvoid excessive heat input due to hot process gases.
ðObserve the maximum permissible media temperature ac-
cording to the technical data.
Labels and signs Keep any signs affixed to the device in an easily readable condi-
tion:
ðConnection labels
ðWarning and information signs
ðMotor data and rating plates
Overheating protec-
tion, blockage pro-
tection
The pump motor has a temperature sensor on the circuit board
as overload protection. In the event of excessive temperature or
if the motor is blocked, the vacuum pump switches off.
Procedure for
switching back on
If the vacuum pump is switched off due to these safety precau-
tions, the error must be cleared manually: Disconnect pumping
unit from power supply -> Eliminate cause of error -> Restart
pumping unit.
The user is responsible for assessing the risks posed by the
equipment in such a way that any safety measures necessary
for installation and safe operation can be implemented.
ATEX approval only applies to the internal, wetted parts of the of
of the device, not to its surroundings.
