2.3 General safety precautions
This operating manual contains important instruc-

must be observed by the owner. As a result, it is
absolutely necessary to turn over the entire docu-
mentation to the specially trained personnel of
the owner or to make it available at the operating
location prior to installation and commissioning.
Prior to installation and commissioning, the entire
operating manual must be carefully read by the
specially trained personnel and then kept in a
safe place. Failure to observe the safety precau-
tions can result in a serious hazard for the per-
sonnel, the pressure vessel or the environment.
Observe the chapter “Manufacturer’s information”
on page 1-1 of this operating manual.
The following safety precautions only refer to the
NK 31 screw compressor module and not to the
entire compressor system.
The applicable national safety and occupational
safety regulations of the respective country in
which the system is operated must be complied
with.
The manufacturer of the compressor system is
responsible for including the necessary safety
regulations for the operation of the compressor
system in the operating manual of the compres-
sor system.

may only be carried out by authorized, trained
and qualified personnel.
The operating personnel is expected to safely
use the working technology and follow all ap
-
plicable local operating safety regulations and
provisions.
The owner bears the responsibility for always
keeping the machine in safe operating condition.
Limits (pressures, temperatures, time settings,
etc.) must be permanently marked.
Should a regulation contained in this list, espe-
cially with regard to safety, not comply with legal
regulations, then the safer of the two applies.
