9. Turn power ON to the air compressor using the customer supplied electrical disconnect.
10. The air compressor will begin running and the pressure in the air tank and nitrogen tank will begin to rise. Start recording the
time it takes until the compressor turns off.
11. Once the nitrogen tank pressure reaches approximately 80 PSI the valves inside the cabinet will close.
12. Once the air tank pressure reaches approximately 175 PSI the air compressor will turn off.
13. If the nitrogen generator is isolated from the sprinkler system:
•
The air compressor of the INS-1500 and INS-2000 should take no longer than 10 minutes to pressure both tanks and turn
off.
•
If the air compressor is not turning off, or it is taking longer than expected, go to the Troubleshooting section in this
manual on page 40.
14. Once the two tanks are pressurized, the amber LED labeled "BYPASS" on the IntelliGen
™
Display will turn off and "Mode"
on the IntelliGen
™
Display will change to "N2
Mode". This indicates that the unit is now in Nitrogen Generating Mode.

Check all piping connections for leaks as pre-plumbed fittings may have loosened during shipment. Any pressure drop on the
tanks during this time could indicate a leak.
