7. System Operation
7.1. General
The nitrogen generator uses valve sequencing to produce nitrogen. The design meets specifications of
a fire protection system. Consult with South-Tek System for written approval before performing any field
changes or customization. Unauthorized changes void all warranties and may cause damages or
malfunctions to the system.
This section describes the major control functions and instrumentations associated with the nitrogen
generators. All programs are proprietary, and password protected from the factory. Do not alter any
controls or instrumentations. Changes without South-
Tek Systems’ written consent voids the
performance specifications.
Note: This section does not include the controls for supporting equipment, such as an external
compressor or
dryer. Consult the original manufacturer’s manual for further information.
