* Do not operate without the water connected, the valve on, and the hose not kinked.
* Do not operate without water (this is permanently installed now so it should be fine.)
* Do not operate without the exhaust blower turned on.
* Beans above 300 F, without cooling air flow or not in motion in the roaster, can catch fire. Stopping the roast is therefore bad. A power outage during a roast is also bad. The roast should be allowed to complete.

* The roast can safely be stopped once bean temperature reaches the target, the cooling cycle engages, and the beans drop to 370 F. When this happens, the yellow Reset light will illuminate. Beans can be allowed to cool in the chamber, or the roast stopped with the Stop button and the beans then immediately dumped into the cooling hopper by using the lever. Fans on the tabletop in front of the roaster will blow cooling air over the roast beans. Beans will cool in the hopper via cooling fans within about 3-4 minutes after roast.

''Sweet Maria’s is great for the beginning roaster because they provide highly detailed cupping notes, suggestions on what level of roast to use, and their opinion on whether something would make good espresso. But the quality of the beans is a function of the grower, not the importer, and a big part of this adventure is discovery and experimentation. So I’d suggest eventually branching out and trying other importers once you have some experience under your belt. -Ryan''
