SYSTEM USAGE
5.1
INSTRUCTIONS
The N
2
-BLAST
®
Nitrogen Generator is intended to be used to generate nitrogen
and provide nitrogen for the fire protection piping system. Follow the installation
instructions above and only use in an approved environment. The generator
generates enough nitrogen to maintain zone pressure requirements. Please consult
with your local provider for questions not answered in this manual.
The system is design for 24 hour operation, but routine maintenance on the filters
must be performed. See section “System Maintenance” for detail maintenance
instructions.
5.2
START-UP PROCEDURES
The system is shipped ready for power once the equipment line connections are
completed. Connect the pipe or hose to the nitrogen storage tank outlet using
Teflon tape or other pipe connection sealant. All valves should be open and ready
for gas to be distributed. Plug the N
2
-BLAST
®
Nitrogen Generator into a 110VAC
power outlet and turn on the rocker switch. The external air compressor will turn on
if the N
2
storage tank is not already pressurized. If the nitrogen storage pressure is
at or above the system cut-off pressure, the amber “Standby” light will be
illuminated. Once the pressure drops to the cut-in pressure, the nitrogen generator
will start replenishing the nitrogen into the storage tank. The “Operating” green
light will illuminate until the N
2
storage tank pressure reaches the cut-out pressure
(approximately 80 PSI) and the external air compressor will cut off once it reaches
its cut-off pressure.
Use caution when working with pressurized gas, making sure that all fittings
and gas lines are installed correctly. Always leak check (see
section) every line before using the system.
Note: Line leaks will cause the N
2
-BLAST
®
Nitrogen Generator
to run
excessively, shortening its life and cause excess wear on the compressor.
5.3
NORMAL OPERATING PROCEDURES
Once the generator has been started-up and the nitrogen storage tank has been
filled, the system should be left power on. The system will automatic start/stop as
the pressure in the nitrogen storage tank reaches the preset cut-in/out pressures. To
pause or bypass the nitrogen open/close corresponding valves as necessary.

ALARM NOTIFICATION
BlastOff™ - Leak Detection System Alarm
An optional feature that can be included with the system is the BlastOff™ - Leak
Detection System. It is a patented system when installed into the N
2
-BLAST
®
Nitrogen Generator, detects line leaks within the downstream gas lines from the
nitrogen generator to the FPS piping. Line leaks could be due to pin-hole leaks in
