Issue: The INS-PV measured nitrogen level is below 98%.
- Check to ensure that ball valve between INS-PV and sprinkler system is open.
- Ensure the nitrogen generator is in Nitrogen Generating Mode. This can be checked by using a portable nitrogen analyzer. The N2 level % leaving the membrane should be 98% or greater. Note the nitrogen generator needs to be running for accurate nitrogen reading. Call technical support if nitrogen leaving membrane is not 98% or greater.
