AIR BYPASS SETUP (OPTIONAL)
The Air Bypass Option ensures that nitrogen is the only supervisory gas
entering the FPS. It safeguards your installation all while providing piece of
mind knowing the FPS is being filled with nitrogen vs any other gas. It will
alarm if the N2-Blast Generator is being bypassed by the air compressor. It
safeguards against a maintenance technician from inadvertently leaving the
“air bypass” open or the N2-Blast being powered in the off position. It will
provide a visual alarm when it is in alarm mode. See wiring diagram and
installation drawing included with this package. For electronic copies, please
contact your local distributor.
START-UP PROCEDURES
It is necessary to use caution when working with pressurized gas, making
sure that all fittings and gas lines are installed correctly. Always leak check
(see
Checking for Leaks section) every line before using the system.
Note: Line leaks will cause the N
2
-BLAST
®
to run excessively, shortening
its life and cause excess wear on the compressor.
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 installation is
completed per the installation layout drawings. Ensure that you follow the
correct installation drawing per your system’s design. In some cases, a N
2
Bypass system for pre-filling is required in the installations to meet code.
If your system requirements are more complex, please consult your sales
representative or equipment installer for more detailed installation
instructions.
