Safety information
2.4 General safety instructions
Products from VACUUBRAND GMBH + CO KG are subject to
stringent quality testing with regard to safety and operation. Prior
to delivery each product has been tested thoroughly.
2.4.1 Protective clothing

wearing full protective gloves, protective clothing and protective
goggles.
When handling chemicals, wear your personal protective
equipment.
2.4.2 Safety precautions
Use the vacuum device only if you have understood its func‑
tion and this manual.
Replace defective parts immediately, e. g., a broken cable,
faulty ask or faulty hose.
Use only original accessories and components which are
designed for the vacuum technology, such as a vacuum hose,
separator, vacuum valve, etc.
When handling contaminated parts, follow the relevant regu‑
lations and safety precautions, this also applies to equipment
sent in for repair.

Safety information
2.4.3 Laboratory and working materials
DANGER
Hazardous substances could emit at the outlet.
During aspiration, hazardous, toxic substances at the
outlet can get into ambient air.
 Observe the national regulations for safe handling of
hazardous substances.
 Please note that residual process media may pose a
danger to people and the environment.
 Mount and use suitable separators, lters or fume
hood devices.
Risks due to various substances
Pumping different substances or media can cause the substances
to react with one another.
Working substances which get into the vacuum pump with the gas
ow can damage the vacuum pump. Hazardous substances can
deposit in the vacuum pump.
Possible safety precautions, depending on the application:
Flush the vacuum pump with inert gas or air before changing
the medium to be pumped.
Use inert gas to dilute critical mixtures.
Prevent the release of hazardous, toxic, explosive, corrosive
uids, gases or vapors or those that are harmful to health or
the environment, for example, through suitable laboratory facil‑
ities with a fume hood and ventilation control.
Protect the inside of the vacuum pump from deposits or mois‑
ture, e. g, through the provision of a gas ballast.
Be aware of interactions and possible chemical reactions of
the pumped media.
Check the compatibility of the pumped substances with the
wetted materials of the pumping unit.
Contact us if you have concerns about using your vacuum
pump with certain working materials or media.

Safety information
2.4.4 Eliminate sources of danger
Take mechanical stability into account
Due to the high compression ratio of the pump, pressure can de‑
velop at the outlet which exceeds that which the mechanical sta‑
bility of the system allows.
Always ensure that the exhaust gas line is clear and non‑pres‑
surized. To ensure unhindered emission of gases, the outlet
should not be blocked.
Prevent uncontrolled overpressure, for example, due to a
locked or blocked piping system, condensate or clogged
exhaust gas line.
At the gas connections, the connections for the inlet IN and
outlet EX should not be mixed up.
Be 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 8.1.1 Technical data
on page 71
The system to be evacuated as well as all hose connections
must be mechanically stable.
Fix coolant hoses to the hose nozzles such that they cannot
inadvertently become loose.
Prevent condensate reow
Condensate can damage the pump head. No condensate should
ow back into the outlet EX and pump head due to the hose line.
No liquid should accumulate inside the exhaust hose.
Avoid condensate return by using a separator. No condensate
must enter the housing interior via the vacuum hoses.
Preferably lay the exhaust gas hose such that it descends
from the outlet; that is, position it running downward so that no
backup forms.
Prevent backup in
the exhaust gas line
Note mechanical
load capacity

1920901334_EN_PC3000_VARIO_select_Serie_V1.0_050418
Safety information
Incorrect measurement due to an obstructed vacuum line, e.g.,
condensate in the vacuum line can distort the measurements of
the vacuum sensor.
Prevent overpressure > 1060 mbar (795 Torr) inside the suc‑
tion line.
Avoid foreign bodies inside the pump
Particles, liquids and dusts should not get inside the vacuum pump.
Do not pump any substances which could form deposits
inside the vacuum pump.
Install suitable separators and/or lters in front of the inlet.
Suitable lters are, e. g, chemically resistant, clog‑proof and
have a reliable ow rate.
Immediately replace porous vacuum hoses.
Risks during venting
Depending on the application, venting can cause explosive mix‑
tures to form or other hazardous situations to arise.
Risks due to residual energy
After the device has been switched off and disconnected from the
power supply, there may still be dangers at the plug‑in power sup‑
ply due to residual energy:
■Thermal energy: Motor waste heat, hot surface, compression
heat.
Allow the vacuum pump to cool off.
■Electrical energy: In capacitors on the electronics, they have a
discharge time of up to 3 minutes.
Wait for at least 3 minutes until capacitors have discharged.
Observe vacuum
pump dimensioning

Safety information
Risk of burns due to hot surface
The surface of the vacuum pump can reach operating tempera‑
tures higher than > 70 °C, in particualar when pumping heated
media.
Avoid direct contact with the surface.
Use protection against accidental contact if the surface tem‑
perature is regularly elevated.
Allow the vacuum pump to cool off before performing mainte‑
nance work.
The vacuum pump can be damaged due to overheating. Possi‑
ble causes include insufcient air supply to the fan and failure to
maintain minimum distances.
When installing the device, ensure that there is a minimum
distance of 5 cm between the cooling fan and adjacent parts
(such as the housing, walls, etc.).
Always ensure sufcient air supply; if applicable, provide
external forced ventilation.
Place the device on a stable surface; a soft surface such as
foam rubber as a sound absorber can impair and block the air
supply.
Clean polluted ventilation slots.
Remove covers from the device before operating it.
Avoid excessive heat input due to hot process gases.
Observe the maximum admissible media temperature
