1.1 Information about this manual
This manual describes the installation and maintenance of Oxeo inert gas extinguishing systems
Oxeo PR LCP with a pressure reducer (also referred to hereinafter as “system”). Information about
fire detection and electrical control is not part of this manual. Qualified knowledge of the extin-
guishing agent used and the technical details of Oxeo inert gas extinguishing systems Oxeo PR
LCP with a pressure reducer are prerequisites for working with this manual.
This installation and maintenance manual contains neither detailed information concerning proj-
ect planning of the system, nor detailed information concerning operation. For this, observe the
design manual and the operating manual. This manual can be obtained through authorized deal-
ers.
This manual is intended for the installer of the fire extinguishing system.
