FPS-10000, FPS-16500, and FPS-22500 Installation and Startup

This article applies to South-Tek Systems N2-BLAST FPS-10000, FPS-16500, and FPS-22500 fire protection nitrogen generators.

Use this article as a general installation and startup guide for the FPS-10000, FPS-16500, and FPS-22500. Always review the project-specific installation package and any applicable system drawings before installing or energizing the unit.

Before installation

• Confirm the exact model number on the unit nameplate.
• Verify the installation location is indoors, nonhazardous, and within the required ambient temperature range.
• Confirm adequate space is available for service access, piping, and electrical connection.
• Confirm incoming power matches the intended unit configuration.
• Confirm incoming air meets the required temperature, dew point, and pressure conditions before startup.
• Keep all gas lines dry before hookup.

Receiving and preparation

• The unit ships upright in a wooden crate.
• Open the side labeled Open Side and inspect the system for visible damage before installation.
• Unbolt the unit from the crate before moving it.
• Use appropriate lifting equipment to remove the unit and place it in its final location.
• Save the crate if the unit may need to be returned for factory service.

Installation requirements

• Install the system indoors in a nonhazardous area.
• Provide adequate clearance for maintenance, troubleshooting, and access to piping and controls.
• Install the generator and associated equipment in the same general area when possible to reduce pressure drop and simplify service access.
• Follow the project-specific layout and panel/gas connection arrangement for the system.

Electrical connection notes

• These systems require hard wiring.
• Power cords are not included.
• Final electrical connection should be completed by a qualified electrician in accordance with local and site requirements.
• Verify voltage and frequency match the intended unit configuration before energizing the system.

Air supply notes

• Incoming air should be maintained between 40°F and 100°F.
• Water dew point should be less than 40°F.
• Incoming air pressure is typically 100 PSIG minimum and 125 PSIG maximum, unless otherwise configured.
• Incoming air should be set to the design air-in pressure to achieve expected system performance.

Piping and connection checks

• Confirm all gas and piping connections are installed in the correct locations before startup.
• Inspect all fittings and connections before pressurizing the system.
• Use an appropriate thread sealant on fittings where required to help prevent leaks.
• Confirm associated air treatment and pressure vessel equipment are installed and operating correctly before startup.

Startup procedure

1. Complete all installation, piping, and electrical work.
2. Verify the nitrogen storage tank and associated piping are connected correctly.
3. Confirm incoming air supply is available and set correctly.
4. Energize the system.
5. Allow the generator to begin operating and building nitrogen storage pressure.
6. Monitor the unit during the initial run and confirm it builds tank pressure as expected.
7. Once the storage tank reaches cut-out pressure, the system should enter standby.
8. Verify the system remains stable in standby and does not immediately restart without demand.
9. Open the downstream nitrogen path as required by the system arrangement and monitor for proper operation.

Leak checks during startup

Leak checking is an important part of startup. Leaks can cause excessive run time, nuisance alarms, and unnecessary wear on the system.

• Check all external piping and fittings for leaks during startup.
• If tank pressure drops unexpectedly while the unit is in standby, isolate sections of the system to narrow down the leak location.
• If a leak is found, shut down the affected section, relieve pressure safely, and correct the issue before restarting.
• If an internal leak is suspected, inspect the cabinet and associated tubing carefully and use only approved replacement parts.

Important notes

• Improper installation can affect performance and may void warranty coverage.
• Do not energize the system until piping and electrical connections have been verified.
• Do not proceed with startup if the installation environment, incoming air, or power conditions are outside the required range.
