Note:
To reset alarm, turn power off and close the nitrogen tank valves. Turn the
power back on. If the unit goes into “Stand-By” mode and shows an orange
light, the generator is operating properly and you have a leak downstream.
Correct the leaks and resume operation. Contact your distributor or the mfg.
as necessary. This is a safety feature designed to provide a safer operating
environment and to prevent equipment damages or failure
the pipe lines, loose fittings, faulty connection, etc. These leaks are potential safety
hazards, they can cause the nitrogen to deplete quickly, and could cause your N
