8. Start-up Procedures
8.1. Start-up Procedures
Use caution when working with pressurized gas and install all fittings and gas lines correctly. Always
leak check (see Checking for Leaks section) every line before using the system.
Note: Line leaks will cause the N
2
-Blast
®
FPS-500 to run excessively, shortening its life and possibly
causing excessive wear on the compressor.
The system documentation package comes with an installation layout drawing. For electronic copies,
please contact your local distributor. Review the complete installation layout drawings. Ensure that you
follow the correct installation drawing per your sy
stem’s design. In some cases, a nitrogen bypass
system for pre-filling is required to meet code.
If the system requirements are more complex, please consult the sales representative or equipment
installer for more detailed instructions.
Note: The N
2
-Blast
®
comes with 1/2” NPT Female inlet and outlet fittings. Use Teflon tape or similar on
all fittings to prevent leakage. When connecting an external air compressor, complete the startup
procedures per manufacturer before starting the nitrogen generator.
The following are standard installation instructions:
1. Complete the installation procedures in section 5.
2. Check the power connection is correct.
3. Turn the 3-
way ball valve on the generator’s left side to the “Nitrogen Out” position.
4. Open the inlet ball valve on the nitrogen storage tank.
5. Close the outlet ball valve on the nitrogen storage tank.
6.
Push the power button on the left side to the “On” position (up). The air compressor will start up if
the system is under pressurized until the cut-out pressure is reached. If neither the operate or
standby lights come on, check the wiring, and power supply to the generator unit.
7.
Once the system is running, close the tank’s inlet ball valve and monitor the pressure gauge on the
front lower left side of the generator. The pressure gauge will increase to 65-70 PSIG within 2
minutes or less.
a. Once it reaches 65-
70 PSIG, the system will enter “Standby” mode and automatically shuts
off the internal air compressor. Check the “Standby light” on the control panel.
b. Once in standby, note the pressure reading on the front panel. Monitor the pressure for the
next minute for any loss in pressure. If there is a pressure drop, check for leaks around
connection fittings, otherwise proceed to the next step.
8. Open the tank input ball valve and the system will turn on and fill nitrogen to the storage tank.
9. Completely fill the storage tank and allow the nitrogen generator to go into standby mode.
10. Once in standby mode, monitor the tank pressure gauge for 5 minutes and ensure no leaks are in
the tank. Open the tank upper ball valve after verifying that there are no significant leaks.
