GPL 10000 Preventative Maintenance Schedule

Here is the recommended preventative maintenance for the GPL 10000 gas odorizer.

As with any equipment, it is imperative to follow the GPL Odorizers’ maintenance schedule. Failure to do so can void the manufacturer’s warranty.

  1. Check Odorizer Alarms
  2. Check the number of Auto Clears used. If half of the odorizer Auto Clears have been used, identify and troubleshoot the issue using the troubleshooting guide.
  3. Verify that all settings are correct (gas input, alarm levels, injection rate, etc.) and that the unit is odorizing to the desired level.
  4. Ensure that the odorant pump is showing efficiency of 85% (0.85) or greater. If the odorant pump has low efficiency, a hydraulic prime is required.
  5. Check the blanket gas pressure on the odorant tank to ensure that it is at the correct pressure (15-20 PSI).

Monthly Odorizer Check

  1. Download odorant injection logs and audit trail information to ensure that the odorizer is operating correctly. The end-user is responsible for determining when odorization logs are collected and submitted to regulatory authorities.
  2. Check odorant tank level to ensure that odorant volume is sufficient and does not require refilling. Also, ensure that the odorant float gauge is functioning properly.
  3. Check the number of solenoid cycles on the maintenance PLC/HMI screen or web page. If the cycles exceed 1,000,000, change the solenoid.
  4. Check the number of piston seal cycles. The seals will need to be replaced; however, the frequency will vary depending on the site conditions and performance history. When the unit reaches 500,000 cycles, call GPL [(303) 927-7683] to perform a seal life analysis check from the data. Depending on the application, seals can last anywhere between 700,000 to 1,000,000 cycles before re-primes are necessary.

Annual Odorization System Preventative Maintenance

  1. Replace the odorant filter and blanket gas filter. Follow the Pump Odorant Purge Procedure outlined in the Installation Operation and Maintenance Manual.
  2. Replace the odorant pump seals (quantity 2). Follow the Pump Removal and Piston Seal Procedures on page 21 of the Installation Operation and Maintenance Manual.
