To get your EF-05 running for the first time;

• Ensure the media is stocked all the way up to the top and completely fill it with water in order for it to run correctly. It is important that the lid is on air tight.
• Check that the impeller and shaft is seated correctly in its fitting. If this part is not inserted in the impeller fitting, the motor will not run.

If this has been done and your unit is still not working, please contact our Customer Services Team.
