Safety

Note the safety precautions in chapters 6. Installation and connection, and 7. Operation.
The pumps are built according to the generally recognized rules of technology and in accordance with the
occupational safety and accident prevention regulations. Nevertheless, dangers can result during their use
which lead to injuries to the user or others, or to damage to the pump or other property.
Only use the pumps when they are in a good technical and proper working order, in accordance with their
intended use, observing the safety advice within the operating instructions, at all times.
Personnel
Make sure that only trained and instructed personnel or specially trained personnel work on the pumps. This
especially applies to assembly, connection and servicing work.
Make sure that the personnel has read and understood the operating instructions, and in particular the
"Safety" chapter.
Working in a safety-conscious manner
Observe the accident prevention and safety regulations when performing any work on the pump and during
operation.
Do not expose any part of your body to the vacuum.
Open housing parts with notice sticker (see fig. 1) only after separating
mains plug from power source.
Handling dangerous media
Fig. 1: Notice sticker
When transferring dangerous media, observe the safety regulations
when handling these media.
Handling flammable media
Be aware that the pumps are not designed to be explosion-proof.
Make sure the temperature of the medium is always sufficiently below the ignition temperature of the
medium, to avoid ignition or explosion. This also applies for unusual operational situations.
Note that the temperature of the medium increases when the pump compresses the medium.
Hence, make sure the temperature of the medium is sufficiently below the ignition temperature of the
medium, even when it is compressed to the maximum permissible operating pressure of the pump. The
maximum permissible operating pressure of the pump is stated in the technical specifications (see chapter
4).
If necessary, consider any external sources of energy, such as radiation, that may add heat to the medium.
In case of doubt, consult the VWR customer service.
Environmental protection
Store all replacement parts in a protected manner and dispose of them properly in accordance with the
applicable environmental protection regulations. Observe the respective national and international
regulations. This especially applies to parts contaminated with toxic substances.
