Important Information　 As the water proportion and hardness of green beans changes, the color of green beans changes. Input of exact color information is the beginning of the accurate roasting. 1. Roasting can be started only after the drum temperature reaches to the preheat temperature which is set in the machine. For accurate roasting, drum’s preheating temperature should be reset by seasons and green beans storage temperature. 2. Basic components of new program are ① green beans weight ② green beans category(color) ③ roasted coffee color. By the selection of this information, computer calculates the basic values such as 1 st and 2 nd crack temperature and display on the screen. You can make your own specific programs just by modifying these values little by little. Just with adjustment each temperature setting 1~2℃, you can get distinctive roasting result. 3. Green beans weight is the basic information to set the 1 st crack temperature. In auto-mode, you can roast 1 kg and 1. 2 kg. If the weight is not exact, the roasting result may quite different. In manual mode, you can roast from 100 gr at rates of 100 gr. 4. Bean Type is divided in 7 levels according to its color. (‘dark green’, ‘light green’, ‘medium’, ‘light brown’, ‘brown’, and ‘dark brown’) As the category is selected by its color, computer in the machine automatically calculates each crack temperature and last temperature. 5. Roast color Select roasted bean color among ‘light’, ‘medium’, ‘dark’ and ‘pitch dark’, and computer calculates 1 st and 2 nd crack temperature and last temperature according to this color information. Coffee beans roasted by PRO 1 are with darker inside color than surface compared to coffee beans roasted by other machines. So it is not needed to roast in Pitch Dark color for special purpose. 6. Exact Bean Type and Roast Color selection is the basis for accurate roasting programming. 9

Basic Information on Operation For the safety, read below attention points before installation. 1. Taking out the cooling basket. Grab the knob on the front side of cooling slider and pull the cooling slider forward. 2.
