  • Page 6 3) Overheating protection mechanism - The machine automatically stops when the roasting temp reaches the MAX temp to prevent overheating. The gas and power supply are stopped as well. - Do not change the setting temperature due to danger of overheating. 4) Overflowing voltage protection system (Circuit Breaker) - To prevent electrical accidents or injuries the machine is equipped with a circuit breaker that shuts off the power if necessary.
  • Page 7 3. Installation * When installing an afterburner: Do not install it near a fire source! Duct made of heat- resistant material is required. Duct Work (Exhaust facility) Combustion occurs in this equipment and it should be installed in a dry place with good ventilation as close as possible to a wall so that a shorter exhaust pipe can be used.

  • Page 15 Step2 Turn the OPERATION switch to the ON position after checking that the control box lights up. (Note: you should be able to observe a whirring sound after turning on the operation switch.) Make sure that the drum is moving and the exhaust fan is working.
  • Page 16 Step4 Open the access door to the roaster body and open the gas valve inside. *Roaster internal gas valve Step5 Turn the BURNER switch to the ON position after opening all of the gas valves of the roaster (previous steps). (Turning on the burner switch causes ignition that will spark after 15 seconds and the pilot burner will be ignited)
  • Page 17 Step6 Start the warm-up process by adjusting the flame. It is recommended that you preheat the drum sufficiently with low heat evenly as preheating with a strong flame may damage the drum. Please ensure that the drum is rotating before applying heat.
  • Page 18 Step7 Once the machine is sufficiently warmed up and you’ve reached your optimal beginning roasting temperature you will be ready to roast. At this time place the green beans in the Hopper. Please note that some heat transfers from the roaster into the hopper and therefore you should not put the green beans into the hopper until you are ready to begin your roast.
  • Page 19 Step9 Start roasting after feeding the green coffee into the drum. Note: please turn on the timer and ensure that the temperature displays are functioning. • The roast can be adjusted by the Damper which controls volume of the the exhaust air flow during roasting.
  • Page 20 Step10 Once the roast is complete, turn on the cooling motor and the cooling fan before discharging roasted beans. - Cooling motor should be operating in advance to minimize the smoke generated during discharge. Step11 Ensure that the cooler and cooling motor are on and then discharge the roasted beans by open the discharging handle.
