Do not place roaster - Near a hot gas or electric burner or heated oven. - In direct sunlight. - Near water or liquid - In an unventilated area.
9 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 1st and 2nd 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 1st crack temperature. In auto-mode, you can roast 1kg and 1.2kg. If the weight is not exact, the roasting result may quite different. In manual mode, you can roast from 100gr at rates of 100gr. 4. Bean Type is divided in 7 levels according to its color. (‘dark green’, ‘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 1st and 2nd crack temperature and last temperature according to this color information. Coffee beans roasted by PRO1 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.
10 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. Opening & Closing the Chaff Drawer Grab both chaff drawer knobs with both hands, and turn to the counterclockwise at once to open them. (Clockwise for Closing) 3. Opening & Closing the Hopper Grab the knob under the hopper and pull forward to open door. Hopper door is tightly fixed to the machine to make smoke does not leak through the hopper door. If you want smooth door opening and closing, loosen 4 bolts around hopper using hexagon wrench. ========================= ================= If green beans are ready in the hopper during preheating, some beans get hot and this may cause inaccurate roasting. Do not load beans on the hopper until ‘POUR BEANS’ message is displayed. ================================ ===================== Remark ② ①

Lower the temperature a little when you want dark roasting and a lot when you want light roasting.
17 ③ Roast : As Roast Color is selected, the basic temperature settings(1st crack temperature, 2nd crack temperature, last temperature) are calculated by the computer. These temperature settings also can be adjusted by user during setting and roasting. In case you set the new temperature, use buttons. ⓐ The coffee roasting theory IMEX adapted is to measure the bean temperature when crack sounds and decide the roasting method upon the bean temperature change. ⓑ Even though the bean species is same, crack temperature is different depend on the moisture and hardness of beans, preheating temperature, roasting environment condition and storage temperature etc. ⓒ Just with the proper crack temperature and time setting, you can roast your own specific tasted beans. Generally high crack temperature setting makes coffee with good body taste(oily) and low crack temperature setting makes coffee with clean taste. ① 1st crack : 1st crack temperature(ex.178 ℃ ) is set taking in a consideration of the time from 1st crack(ex.175 ℃ ), and this tip can be your roasting secret. Press buttons and set 1st crack temperature. ② 2nd crack : 2nd crack is the bean temperature after making it lower after 1st crack. Proper 2nd crack temperature is 10~12 ℃ higher than 1st crack temperature. Set the 2nd crack temperature using buttons. Remark Remark Press after Roast Color selection to change screen to Save Mode. 6. New Setting Mode – Bean Temperature Mode ① ② ③ Last bean temperature largely affects whole coffee taste.
