Potter IntelliGen
™
Nitrogen Generators are designed to provide maintenance alerts that ensure the long life of the nitrogen
generator. These alerts also ensure that the unit runs at peak efficiency. The IntelliGen
™
Nitrogen Generator has an internal
maintenance timer that monitors how long the unit has been operating since it has been serviced. Normal scheduled maintenance
should be done every 1,000 compressor operating hours, or during the annual inspection of the unit, whichever comes first.
When the system needs maintenance, the amber maintenance light on the IntelliGen
™
Display will turn on. If connected to
the internet, you will receive an e-mail notification as well. If maintenance on the nitrogen generator is not done within 250
compressor operating hours, the nitrogen generator will show a trouble condition.
To reset the maintenance timer and get the maintenance alert to reset, go to the IntelliGen
™
Display.
1. Press "MAINT" on the IntelliGen
™
Display keypad.
2. Enter passcode "0000".
3. Select “Std. Maintenance” and press "ENTER".
4. The menu will then display the count down hour log on the Maintenance Timer. Press "ENTER" on the keypad to clear
Maintenance Timer. Press "ENTER" to confirm.
5. The amber Maintenance LED will turn off.

Clean all external parts of the compressor and motor.
•
Manually test safety relief valves.
•
Inspect system for leaks.
• Tighten fittings, nuts and screws as required.
•
Check the pressure settings.

Maintenance and Part Replacements
All pressure must be relieved from the entire nitrogen generator system BEFORE servicing. To avoid system damage
and/or personal injury, the nitrogen generator should be isolated from the sprinkler system and the generator system fully
depressurized before any maintenance or service is performed. All maintenance and troubleshooting activities for the Potter
Nitrogen Generator should be performed by qualified personnel using reasonable care. Before servicing, isolate all risers by
closing all Air Maintenance Device valves and relieving all system pressure from the Potter Nitrogen Generator. Failure to
do so could result in serious injury or death. Ensure power is turned off at the electrical disconnect.
