Vacuum system SC820G / SC840G
Working with
combustible me-
dia and explo-
sive atmosphere
Translation of Originial Operating Instruction, KNF 339416-339418 02/23
When pumping hazardous media, follow the safety regula-
tions that apply for working with these media.
Note that the vacuum system is only suitable for pumping ex-
plosive atmosphere according to its designation (see type
plate) and must not be set up in potentially explosive atmos-
pheres.
Make certain that the temperature of the medium is always
sufficiently below the ignition temperature of the medium so
as to prevent ignition or explosion. This also applies for ab-
normal operating situations.
At the same time, note that the temperature of the medium
rises as the pump compresses the medium.
Therefore, make certain that the temperature of the medium
also remains sufficiently below the ignition temperature of the
medium even when it is compressed to the maximum permis-
sible operating pressure of the vacuum system. The maxi-
mum permissible operating pressure of the vacuum system is
given in Chapter 5 Technical data [} 25].
Make certain that the permissible ambient temperature (see 5
Technical data [} 25]) is not exceeded.
Where applicable, also take into account external energy
sources (such as radiated heat sources) that might heat the
medium further.
In case of doubt, contact KNF Customer Service.
3.6 Use
3.6.1 Proper use
The vacuum systems are intended exclusively for delivering
gases and vapors.
The vacuum systems are intended exclusively for operation in
indoor areas and in non-explosive atmospheres. The Ex des-
ignation is valid only for the pumping chamber (media-con-
tacting area).
Vacuum systems with ATEX designation do not always
conform to the regulations governing potentially explo-
sive atmospheres in countries outside the EU.
