Improper Use; Safety - VWR VP 8 Vac Manuel D'instructions

English
Only transfer gases which remain stable under the pressures and temperatures occurring in the pump.
High performance condenser
The high performance condenser must be installed on the outlet side of the pump; if it is installed on the inlet
side there is a danger of implosion.
Observe the correct usage of the gas- and cooling liquid-connections on the high performance condenser.
Inlet and outlet connections for the gas are not interchangeable.
Accessories
Laboratory equipment or additional components connected to a pump/system have to be suitable for use
with the pneumatic capabilities of the pump (see chapter 4).
2.2

Improper use

The pump/system may not be operated in an explosive atmosphere.
The pump/system is not suitable for transferring dusts.
The pump/system is not suitable for transferring liquids.
The vacuum system must not be used if the entry of air or gas into the vacuum system during venting
(safety vent valve) could result in the creation of reactive, explosive or otherwise hazardous mixtures (e.g.
with the medium).
The pump/the system must not be used to create vacuum and overpressure simultaneously.
An overpressure must not be applied to the suction side of the pump/the system.

Safety

Note the safety precautions in chapters 6. Installation and connection, and 7. Operation.
The pump/system is 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/system or other property.
Only use the pump/system when it is in a good technical and proper working order, in accordance with its
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
pump/system. 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/system 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 pump/the system is 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).
