What are the available temperature settings on the MD-31, and when should I use each one?

The MD-31 offers four temperature settings: Regular (for sturdy cottons or items labeled 'Tumble Dry'), Medium (for permanent press, synthetics, or lightweight cottons), Delicate (for heat-sensitive items labeled 'Tumble Dry Low' or 'Tumble Dry Warm'), and Air Fluff (tumbles without heat, for sensitive loads or items needing freshening). Note that using the Air Fluff setting will require a longer drying time. (Pages 4–5)
