Troubleshooting

---

If little or no air is coming through the diffuser, check the following:

• Check for pipe kinks or obstructions in the airline tubing.
   
• Inspect the diffuser to ensure it isn’t silted up or buried in sediment.
   
• Clean the diffuser pores. white vinegar is effective for removing mineral buildup.
   
• Check pump diaphragm performance. Diaphragms can wear over time and may need replacement.

 If unsure, contact SAS for service or replacement parts.

If you see large or uneven bubbles, this usually indicates an issue with the diffuser positioning or membrane integrity.

• Over time, the diffuser tray may have flipped upside down. Use a grappling hook and rope to gently turn it back into position.
   
• Check that the EPDM rubber membrane is intact. Tears or splits will allow excessive air to escape and reduce efficiency.

If the system fails to turn on or off according to the schedule:

• Reset the timer. Press the small recessed reset button (use a screwdriver tip or similar), then re-enter the current time and schedule.
   
• Check battery voltage. If below 11.5 V, the controller may shut down automatically during extended cloudy or anticyclonic weather.

Wait for a sunny period, and the system will automatically re-establish the timing cycle once recharged.
 

• Assess battery condition. Older batteries may show >12 V when idle but drop below 11.5 V under load, causing shutdowns.

 If this occurs, replacement batteries are recommended.

If your system shuts off earlier than usual:

• Check battery voltage. If below 11.5 V, reduced sunlight may have limited charge capacity.
   
• Allow recharge time. After several sunny hours, the system will resume full cycles automatically.
   
• Adjust the timer schedule for shorter run periods during extended cloudy spells.
