Vacuum Pump System SC 920G 

Translation of original Operating Instructions, English, KNF 121308-121311 07/18 

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. 

 

 

Ensure that the employees check that the hand terminal is the right 
one for this particular system before using a SC 920G vacuum 
pump system. Vacuum pump systems are equipped with a paging 
system for this purpose (see Actuating the vacuum pump system, 
page 29).

 

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.
