How much space do I need around the air fryer for proper operation?

You must provide at least 6 inches (15.25 cm) of space above and on all sides of the appliance for proper air circulation during operation. Do not place the appliance near the edge of a worktop during use, and do not cover the air intake vent or air outlet while the unit is operating, as this will prevent even cooking and may damage the unit or cause it to overheat.
