5. Setup and Installation

Proper setup is crucial for safe and effective operation.

1. **Unpacking:** Carefully unpack all components and verify against the packing list.
2. **Placement:** Place the roaster on a stable, level surface in a well-ventilated area. Ensure sufficient clearance around the machine for airflow and maintenance.
3. **Electrical Connection:** Connect the roaster to a grounded electrical outlet (Single phase 220V/50 or 60Hz).
4. **Gas Connection (Gas Models):** Connect the gas supply to the roaster using appropriate fittings and hoses. Ensure all connections are secure and leak-free.
5. **Exhaust System:** Install the smoke evacuation pipe and connect it to an external ventilation system to safely exhaust smoke and odors.
6. **Chaff Collector:** Ensure the chaff bucket is correctly positioned and secured.
7. **Initial Inspection:** Before first use, visually inspect all connections, moving parts, and controls for any damage or loose components.

6. Operating Instructions

Follow these steps for a successful roasting cycle:

1. **Pre-heating:** Turn on the roaster and activate the 'Warm Up' function. Allow the drum to reach the desired charge temperature (typically 180-200°C, depending on bean type and desired roast profile). Monitor the temperature displays.
2. **Loading Green Beans:** Once the roaster is pre-heated, open the feeder funnel and carefully pour the measured quantity of green coffee beans (500g-3200g) into the drum. Close the funnel securely.
3. **Initiate Roasting:** Start the roasting process. Adjust the heat controls (gas valve for gas models, power for electric models) and airflow (manual dampers) according to your desired roast profile.
4. **Monitoring:** Continuously monitor the roasting process using the sight glass, burner window, and real-time temperature displays. Use the sampler spoon to periodically check bean development and color.
5. **Data Logging:** Connect your mobile phone via Bluetooth or computer via USB to use Artisan Software for data logging, tracking temperature curves and roast progression.
6. **First Crack:** Listen for the 'first crack' sound, indicating the initial stage of bean expansion. Adjust heat and airflow as needed.
7. **Second Crack (Optional):** For darker roasts, continue until the 'second crack' is heard.
8. **Discharge:** Once the desired roast level is achieved, quickly discharge the roasted beans into the cooling tray.
9. **Cooling:** Activate the cooling tray agitator and cooling air to rapidly cool the beans. This stops the roasting process and preserves flavor.
10. **Shutdown:** After cooling, turn off all heating elements, fans, and the main power switch.

7. Maintenance and Care

Regular maintenance ensures the longevity and optimal performance of your roaster.

Daily Maintenance:

• **Chaff Collector:** After each roasting session, clean the chaff collector to prevent buildup and maintain proper airflow.
• **Exterior Wipe Down:** Wipe down the exterior and control panel with a damp cloth.

Weekly/Bi-Monthly Maintenance:

• **Internal Surfaces:** Clean internal surfaces accessible without disassembly.
• **Drum Cleaning:** If the drum is removable, remove and clean it thoroughly.
