3. Safety
The vacuum pump system is built according to the generally recog-
nized 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 vacuum pump system or other property.
Only use the vacuum 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.
Make sure that only trained and instructed personnel or specially
trained personnel work on the vacuum pump system. This
especially applies to assembly, connection and servicing work.
Make sure that the personnel has read and understood the opera-
ting instructions, and in particular the "Safety" chapter.
Observe the accident prevention and safety regulations when per-
forming any work on the vacuum pump system and during opera-
tion.
Do not expose any part of your body to the vacuum.
Open housing parts with notice sticker (see fig. 1) only after sepa-
rating mains plug from power source.
When transferring dangerous media, observe the safety regula-
tions when handling these media.
Be aware that the vacuum pump 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
vacuum pump system. The maximum permissible operating pres-
sure of the vacuum pump system is stated in the technical speci-
fications (see chapter 4, page 8).
If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
When ventilating the vacuum pump system with air or inert gas, be
sure to prevent formation of reactive or explosive media. The
system
maximum permissible operating pressure at the ventilation
connection (Fig 2/5, page 11) is 0.1 bar g.
