2. SAFETY GUIDELINES
The following section outlines the basic safety considerations about installation and operation of the
N2BLAST® FPS-1650, FPS-3250, and FPS-5000. For other equipment used with the nitrogen
generator, such as air compressors, and dryers, refer to the manufacturer’s safety guidelines.
2.1 General
Using the FPS-1650, FPS-3250, and FPS-5000 correctly is important for safety and trouble-free
operation. Wrong use can cause damages to the system or can lead to incorrect gas supply. The
nitrogen generator produces nitrogen at a low flow rate, which quickly dissipates into the air. Nitrogen
is not poisonous, but do not directly inhaled, since high concentrations, can cause asphyxiation.
Install the unit in a well-ventilated room, unsealed off from normal living space air changes.
Read carefully and act accordingly before installing, operating, or repairing the unit:
• Operator must use safe working practices and rules when running the nitrogen generator.
• The owner is responsible for always keeping the unit in safe working conditions.
• Always use approved parts when performing maintenance and repairs. Make sure that
replacement parts meet or exceed the original parts’ specification.
• Only competent individuals, train and authorized, can install, operate, perform maintenance,
and repair.
• Isolate incoming and outgoing pressures to the generator, and depressurize the service or
repair section before performing any mechanical work, including changing the filters. Vent the
nitrogen generator’s exhaust gas outside or to a large, well-ventilated room to avoid
suffocation due to lack of oxygen.
• Wear safety glasses if the cabinet door is open while the machine is running.
• Use ear protection when the equipment is running.
WARNING: Components may experience pressure during operation. Pressurized gases are
dangerous and may cause injury or death if handled or used inappropriately.
• Never allow pressurized gas to exhaust from an unsecured hose. An unsecured hose may
present a whipping action, which can cause serious injury. If a hose burst during use,
immediately close all isolation valves if safe and turn off the unit.
• Never disable or bypass any safety relief valves.
• Always disconnect the nitrogen generator the supply power prior to performing electrical work.
NOTE: Always following local and site safety regulations in conjunction with this manual. Correct use
of the nitrogen generator is important for personal safety. Incorrect safety practices can cause damage
to the individual and equipment.
Follow safe working practices, OSHA, and local health and safety regulation when installing and
maintaining the N2BLAST® FPS-1650, FPS-3250, and FPS-5000.

4. SITE AND UTILITY REQUIREMENTS
4.1 Air Supply (for FPS-3250 and FPS-5000 Models Only)
(Note: N2BLAST® FPS-1650 models have integrated compressor with acceptable air filtration.)
Keep the nitrogen generator’s air supply between 40-100° F (4-38° C) and a water dew point less than
40° F (4° C). Exceptions are available for custom designed units. Air supply that does not meet these
requirements may cause damages not covered by warranty. Other equipment, such as the air dryer
and pressure vessels, must meet minimum design specifications to function properly. Contact South-
Tek Systems or the local installer for any questions about air supply requirements.
The nitrogen generator’s incoming minimum and maximum air pressure is 100 PSIG and 125 PSIG,
respectively, unless otherwise configured. Set the incoming air pressure at the design air in pressure
to meet purity and flow specifications. Operation at other pressures may result in unwanted
performance and damages to the generator’s components. Air consumption depends on nitrogen
product purity and flow rate. Please consult South-Tek Systems for specific details.
4.2 Additional Piping and Hosings
Sourcing and installing piping and hosing components are by others. They must meet the max feed
air at system’s pressure, which can be up to 3 times the specified average feed air flow-rate. Consider
all incoming feed air flow-rate references on the nitrogen generator as average feed air unless
otherwise noted. If piping length from the air receiver is greater than 50 feet, consult with a piping
contractor for proper line size.
4.3 Electrical Requirements
The N2BLAST® FPS-1650, FPS-3250, and FPS-5000 requires 120-240VAC / 50-60hz / 1ph. The FPS-
1650 draws < 8A, the FPS-3250 and FPS-5000 draws < 5A. They have a built in 20A over-current
protection device and comes with a standard 3-prong US power cord for the electrical connection
(unless otherwise specified). They comes with UL 508A ICP certification, and the electrical schematic
are available upon request.
4.4 Site Specifications
Unless designed otherwise, install in a nonhazardous indoor location with temperatures between 40-
100°F (4°- 38°C). For ease of maintenance, troubleshooting, and minimizing pressure drop, install the
equipment in the same area. Leave enough space around the generator and other equipment for
routine maintenance.

6. SYSTEM DESIGN
6.1 Key Features
The N2BLAST® FPS-1650, FPS-3250, and FPS-5000 key features:
• Air compressor (for FPS-3250 only)
• Safety Relief Valves
• Air Filters
• Automatic Pressure Cut-in/Cut-out
• Programmable Logic Controller (PLC)
• N2 Tank
• Pressure Swing Adsorption Beds
• STS Patented Blast Off®
6.1.1 Air Compressor (for FPS-1650 Only):
An oil-less internal air compressor has an engineered dampening system reducing vibration and
noise throughout the cabinet. The air compressor has a pre-filter to catch small particulates that
can cause damage. The recommended replacement for the pre-filter is 1000 run hours or 1-year,
whichever comes first. Dirtier environments may need more frequent changes. Consult with the
supplier for a different filter maintenance schedule if installing in a dirty environment.
6.1.2 Air Filters:
The generators have two filters between the compressed air and O2 separation beds - the
particulate and coalescing. The FPS-1650 has an air inlet pre-filter, and the FPS-3250 and FPS-
5000 will have an additional absorbing filter. The 5 micron particulate filter catches the bulk
particles, and the 0.1 micron coalescing catches the remaining smaller particles. Both filters feature
an auto-drain that drains any water buildup within the filter housing. These FPS-1650 drain lines
are on the cabinet’s lower left side. The FPS-3250 and FPS-5000 drain lines are on the cabinet’s
bottom. Connect these drain lines to a safe location. The FPS-3250 and FPS-5000 absorbing filter
does not require drain plumbing because it does not have an auto-drain.
6.1.3 Programmable Logic Controller (PLC):
An integrated PLC within the cabinet, features smart and efficient coding to maximize the
generator’s performance. It controls the valve timing and sequencing to move compressed gas
throughout the system. It also has a smart feature to go automatically into different “modes” based
on the current run stages. It comes with a touchscreen with many display options. (See Chapter 7:
System Operation for more about the program’s functionality).
6.1.4 Safety Relief Valves:
The installed ASME safety relief valves adds additional safety to protect component failures.
6.1.5 Nitrogen Tank:
A nitrogen tank inside the cabinet comes with ball valves, safety relief, and a gauge. The outlet gas
connects to an external manual ball valve for easy plug and play connection.
6.1.6 Automatic Cut-In and Cut-Out:
The generator starts and stops based on an analog signal to the PLC from the built-in pressure
transducer. Do not adjust the factory preset cut-in and out pressure without first consulting with
South-Tek Systems.

6.1.7 Patented Blastoff® Leak Detection:
The “BlastOff® Leak Detection” is a patented feature which sends an alarm if it detects a possible
gas leak. The alarm signal can be an audible, visual, and dry contact connection to the “Building
Management System’s (BMS)”. Power cycle the unit to reset the alarm, but avoid doing this multiple
times without finding the cause as it will shorten the generator’s life.

7.4 Operation
The following images display the “Off”, “Standby”, and “Running”. A status icon on each equipment
indicates the status. The check mark [P] indicates the equipment working properly where a warning
symbol [^] indicates an issue. Gas flow animation with small white blips travels along the appropriate
path (Air = Blue; N2 = Green). After initial alarm, all alarm screens will time-out and revert to this
operation screen. Gray piping with no animation mean no moving gas. The alarm triggered is displayed
in the upper right corner “Status Bar”.

7.4.1 Bypass Alarm
During the 30-minute fire protection piping system fill test, or if the
generator is not functioning correctly, the “Bypass Alarm” triggers.
This generator automatically switches over to the external air
compressor. This bypasses nitrogen production until the fire
protection piping system no longer demands the increased gas
flow. Press the red bell icon to temporarily silence the buzzer. The
generator will automatically return to normal nitrogen operation.
7.4.2 BLASTOFF® Alarm
The system activates a BlastOff® Alarm when it detects potential
leaks or nitrogen being overdrawn. The operation screen will
appear and with a status notification in the upper right corner
flashing “BlastOff”. Press the red bell icon to temporarily silence the
buzzer. Inspect and test the system for leaks and component
failures. Contact South-Tek System or your local installer for further
troubleshooting.
7.4.3 Compressor Issue Alarm
When the nitrogen generator detects an issue with the air
compressor, it will jump to the operation screen and display a
warning symbol on the air compressor. Press the red bell icon to
temporarily silence the buzzer. Check the air compressor for power,
line leaks, or other equipment failures in order to get the nitrogen
generator running properly again. Contact South-Tek System or the
local installer if further troubleshooting.
7.4.4 Dryer Issue Alarm
When the nitrogen generator detects an issue with the air dryer, it
will jump to the operation screen and display a warning symbol on
the air compressor. Press the red bell icon to temporarily silence the
buzzer. Check the air dryer for power, line leaks, or other equipment
failures in order to get the nitrogen generator running properly again.
Contact South-Tek System or the local installer if further
troubleshooting.
