N2-GEN™ HPC Deployable — Installation & Startup – South-Tek Systems

Applies to: N2-GEN™ HPC Deployable (HPC-01DD-A)

This article covers receiving, site selection, electrical connection, and first startup of the N2-GEN™ HPC Deployable. Contact South-Tek Systems to schedule commissioning before operating the system for the first time.

Receiving and Unpacking

The HPCD ships strapped to a wooden pallet with plastic wrap around the hard case. Upon receipt, remove the plastic wrap and strapping and inspect all parts for damage. Report any findings to the carrier and to South-Tek Systems' service department. If there is significant damage to any shipping materials, note it on the bill of lading before signing.

Open the storage compartment on top of the case and confirm the following items are present before proceeding:

High-pressure fill hoses
20 ft electrical power cable (IEC 60309 connector)
Product documentation (O&M manual and Quick Start Guide)

Read all documentation fully before continuing with installation or operation.

Site Selection and Positioning

Select a site that meets the following requirements:

Ambient temperature between 40–104°F (4–40°C)
Relative humidity no greater than 90%
Elevation no greater than 4,500 ft — nitrogen output decreases above this elevation
No more than 5 degrees off level
Reasonably clear of dust, debris, and solvents
At least 2 feet of clear space on all sides of the hardcase for ventilation and access

⚠ WarningNever place or stack objects on top of the HPCD. The case top must remain in place during operation to prevent foreign objects, rain, dust, and dirt from entering the system. The top should only be removed to retrieve accessories or perform maintenance.

Electrical Connection

The HPCD requires a 208–240 VAC / 50–60 Hz / 1 Phase outlet. A 20 ft power cable is supplied with the unit. The cable has an IEC 60309 twist-locking receptacle on one end and flying leads on the other. If hardwiring to the electrical cabinet is preferred, use the supplied electrical schematic and have the work completed by a certified electrician.

⚠ WarningConfirm the main power toggle switch is in the OFF position before connecting the power cable. A certified electrician must review all electrical connections before system operation. Do not use a generator or power supply that does not match the specified voltage, frequency, and amperage.

Schedule Commissioning

Once the system is positioned and connected to power, contact South-Tek Systems to schedule an in-person or remote commissioning before first operation. The system should not be started without completing this step.

ℹ NoteContact South-Tek Systems at (910) 415-1880 (dial 1 for callback) or submit a ticket at support@southteksystems911.zendesk.com to schedule commissioning.

Pre-Startup Checks

Before powering on the system for the first time or after any period of storage, complete the following checks in order:

Open all six ventilation ports on the case using the thumb screws. This must be done before every fill cycle.
Confirm both pressure gauges read zero. If either gauge shows pressure, wait until all pressure is fully relieved before proceeding.
Verify the fill selector ball valve on the control panel is set to the desired fill pressure (2200 or 3500 PSIG).
Visually inspect all high-pressure hoses and CGA fittings for damage, wear, or loose connections. Actuate each ball valve to confirm freedom of movement.
Confirm the cylinder to be filled is properly secured upright and its valve is closed.
Verify that the cylinder and all connected equipment are rated for the selected cut-off pressure.

⚠ WarningAll six ventilation ports must be open before starting. Operating with the ports closed will cause components to overheat and may result in permanent damage to the system.

Powering On

Once all pre-startup checks are complete and the cylinder is attached and secured, toggle the main power switch to the ON position. The green Operate light will illuminate confirming power is connected correctly.

After the switch is turned on, there is a 2-minute startup delay before the compressors begin running. During this delay, no action is required. Once the delay is complete, the compressors will start and begin pressurizing the internal storage tank. The air inlet pressure gauge will move to approximately 100–105 PSIG, which is the normal operating pressure of the internal compressors.

ℹ NoteOnce the internal storage tank reaches and maintains approximately 50 PSIG, the electric booster will start and begin filling the cylinder. During the first hour of operation, periodically check the gauges to confirm the cylinder is filling as expected.

Purging High-Pressure Lines

After the system starts and before closing the cylinder valve to begin filling, open the T-handled valve near the cylinder head for approximately two minutes. This purges any elevated oxygen concentrations from the booster and high-pressure lines. Always exercise caution when opening valves on high-pressure components.

▲ AttentionAllow the system to purge through the T-handle valve for at least two minutes before closing the valve and beginning the cylinder fill. When draining pressure higher than 100 PSIG, open and drain slowly — the muffler may burst if flow is not regulated.

Once purging is complete, close the T-handled valve and open the cylinder valve to begin filling. For detailed step-by-step cylinder filling procedures, including 2200 PSIG and 3500 PSIG fill sequences, refer to the N2-GEN™ HPC Deployable — Cylinder Filling Operation article.
