An 110VAC power connection should be installed per local code by a qualified
electrician. See the wiring diagram for specifics. Optionally a standard
110VAC power cord can be installed on the system by a qualified electrician.
Warning: Secure the N

Nitrogen Generator to the wall at the top
and bottom flanges. Failure to do so could cause damage or bodily injury.

INSTALLATION (FOR N

-BLAST
®
NITROGEN GENERATOR)
The installation layout drawings are provided with your system in the
documentation package of the system. For electronic copies, please contact your
local distributor. Review and make sure the setup installations are followed per the
installation layout drawings. Ensure that you follow the correction installation
drawing per your system’s design. In some cases, a nitrogen bypass system for pre-
filling is required in the installations to meet NFPA (National Fire Protection
Association) code.
If your system requirements are more complex, please consult your sales
representative or equipment installer for more detailed installation instructions.
1.
The N

-BLAST
®
Nitrogen Generator is designed with ½” inlet/outlet
connections. Use Teflon tape or similar on fittings to prevent leakage.
2.
Install the “Supply Line” coming from the air compressor to the N

Nitrogen Generator Air Inlet.
3.
Connect the N

-BLAST
®
Nitrogen Generator to the storage tank and then
to the systems Air Maintenance Device(s).
4.
Once connections are made and the air compressor has been started
up, slowly open the System’s On/Off Valve.
a.
Air will start rushing through the nitrogen generator
b.
If there is a leak or bad connection, shut valve off, depressurize the
line, and fix the issue.
c.
If a leak within the unit, remove top cover and locate the issue.
Only use factory parts supplied from your distributor or South-
Tek Systems. Consult the factory for any questions.
5.
Once the N

-BLAST

Nitrogen Generator
fills the nitrogen storage tank
to t h e c u t - o u t p r e s s u r e ( ~ 80 PSIG), the system will enter standby -
green light on the control panel will turn off and orange (standby) light
will turn on. This will stop the air flow through the generator and
eventually stop the air compressor once it reaches the cutout pressure.
a.
This will save air and time on the compressor’s motor.
b.
This also prolongs life of nitrogen generator’s media and filter life.
i.
Lesser quality systems have a constant purge flow
through their systems which decreases system life and
increases the need for maintenance.
6.
When you draw nitrogen
from the system and the tank pressure falls
below cut-in pressure (approximately 72 PSIG), the pressure switch will
trigger the system back into run mode and refill nitrogen into the storage
tank automatically. The pressure switch is preset at the factory – no field
