Depending on the roaster size, you also may need a green coffee loading hopper with conveyance system.

If a problem should arise, is Tech Support available?

Yes, tech support is available and can be reached during our business hours.

We are getting an air failure light on the control panel and when we put air through the roaster, we can’t get it to light. Is there a sensor or something we need to check?

If you are seeing an air failure, you’ll want to start by cleaning the roaster and ducting, scrape down to metal and check the vacuum sensor tube, This tube senses air flow through the roaster.

Use a small tool to clean out any debris to clear the tube. DO NOT put a vacuum on it or blow compressed air through it. We will also want to ensure that the blower shroud, internal roaster pipes (back exhaust elbow) are all in place and doors are shut tightly.
