K&A - Monthly Compressor Maintenance Procedure

This procedure ensures proper function, efficiency, and longevity of the compressor by performing basic monthly maintenance: checking and refilling oil, draining water, and inspecting the air filter. Please refer to this VIDEO for further help.

It is recommended that a Monthly Compressor Maintenance Log is kept and updated or a machine tag is kept on the compressor:

🔧 Tools & Supplies

  • Lint-free wipes

  • Oil (approved type from manufacturer)

  • Crescent wrench

  • Allen wrench (for filter assembly)

  • Flashlight (optional, for visual inspection)

  • Maintenance log

⚠️ Warnings

  • Always power off and depressurize the compressor before maintenance.

  • Orange or very dirty water may indicate a major internal issue—report this immediately.

  • Do not overfill oil past the halfway point of the sight bubble.

✅ Step-by-Step Instructions

  1. Note the Compressor Pressure
    • Note the current compressor pressure at both the instrument gauge and the compressor gauge itself to ensure there are no anomalies
             
    • Typical ranges at instrument: 0.30 -.040MPa (43-58 psi) 
    • Typical ranges at the Compressor: 0.41 MPa-0.55MPa (60-80 psi)

      Note: The compressor must always supply more pressure than the instrument is demanding otherwise it will behave as if it has a leak in the compressor air system.

  2. Run SHUT DOWN Sequence 

    • In the software go to the Manual Control Screen

    • Follow all on-screen prompts until the liquids are in their respective bottles.

    • Double check to make sure no fluid remains in the liquid lines or waste lines.

    • Once the lines are dry, close the Argon and Compressor Pressure turn Valves.

      WARNING: FAILURE TO DO THIS CORRECTLY COULD LEAD TO CROSS CONTAMINATION OF REAGENTS. NEVER TURN OFF COMPRESSOR PRESSURE UNTIL ALL BOTTLES HAVE BEEN DEPRESSURIZED

  3. Power Down and Vent System

    • Turn off the compressor using the main switch.

    • If needed, open the manual ventilation valve to release trapped pressure.

  4. Check Oil Level

    • Locate the oil sight bubble (usually on the compressor’s right side in North American builds).

    • The oil should be at the halfway mark of the bubble.

    • If low, continue to the next step

  5. Add Oil (If Necessary)

    • Use the compressor oil that came with the Compressor if available but standard air compressor oil from a hardware store will suffice.

    • Remove the oil cap and slowly add oil using a clean funnel or tubing.

    • Watch the bubble closely—stop filling once halfway full.

    • Close the oil cap and secure it.

  6. Drain Water Trap

    • Locate the water trap release valve

    • Place a container to collect any water or residue under the tube connected to the valve

    • Open the drain valve to release any water or residue into the collection vial

    • Close the valve once fully drained.

    • Inspect the drained water:

      • Clear or slightly cloudy – Normal

      • Orange, rusty, or sludgy – Flag this in the log and notify service immediately because if it is excessive you will likely need a new compressor.

             

  7. Inspect Filter and Tubing

    • Visually check the air filter for dirt or damage. The filter should be either white or green. Replace if you see discoloration.

    • Inspect compressor tubing for clogs, damage, or improper positioning.

      Consider replacing the tubing if the compressor filter was very discolored as particulates or oil may have gotten into the tubing

       

  8. Record & Report

    • Log oil level, water condition, and filter status in the monthly maintenance log.

    • Note any issues or anomalies and alert Sierra BioSystems
