2. Safety Instructions
WARNING: Failure to follow these safety instructions may result in injury, fire, or damage to the equipment.
- Electrical Safety: Ensure the furnace is connected to a grounded AC110V power supply. Do not operate with wet hands or in damp conditions. Disconnect power before any maintenance or cleaning.
- High Temperature Hazard: The furnace operates at temperatures up to 1100°C. Always use appropriate heat-resistant gloves and protective eyewear when handling materials near or inside the furnace. Allow the furnace to cool completely before opening the chamber or performing maintenance.
- Flammable Materials: Keep all flammable materials away from the system perimeter. Never place combustible items within the furnace chamber's radiation range.
- Ventilation: Operate the furnace in a well-ventilated area to dissipate heat and any fumes produced during the heating process.
- Stable Placement: Install the furnace on a stable, heat-resistant surface with a minimum of 25cm clearance from walls and other objects to ensure proper airflow and prevent heat transfer. Avoid direct sunlight exposure.
- Automatic Door Closing Detection: The furnace will not initiate heating until the furnace door is confirmed to be tightly closed. Ensure the safety door latch is engaged before operation.
- Overheating Protection: The integrated cooling fan and heat emission holes effectively dissipate excess heat. Do not obstruct these vents.
- Temperature Precautions: If the ambient temperature is below 15°C (e.g., after transport), allow the unit to sit at room temperature for at least 30 minutes before startup.

5. Setup
Proper setup is crucial for the safe and efficient operation of your furnace.
- Placement Requirements:
- Install the furnace in a dry indoor environment.
- Ensure a minimum of 25cm (approximately 10 inches) clearance from walls and other objects on all sides to allow for adequate heat dissipation.
- Avoid direct sunlight exposure, as this can affect temperature readings and component lifespan.
- Place the furnace on a stable, level, and heat-resistant surface.
- Temperature Precautions:
- If the ambient temperature is below 15°C (e.g., after transport or storage in a cold environment), allow the furnace to acclimate at room temperature for at least 30 minutes before startup. This prevents condensation and potential damage to electronic components.
- Heat Resistance Precautions:
- Ensure the mounting surface has adequate heat resistance. While heat radiation and thermal effects are within safe limits, prolonged use may cause slight discoloration on furniture surfaces or veneers if not properly protected.
- Power Connection:
- Connect the provided power cable to the furnace's power input socket (AC 110V) located at the rear.
- Plug the other end into a grounded AC110V electrical outlet.
- Ensure the main power switch on the rear of the unit is in the OFF position before connecting to power.
6. Operating Instructions
Follow these steps for operating your BEILOCKERY Resistance Furnace:
- Power On:
- Ensure the furnace is properly set up and all safety precautions are observed.
- Flip the main power switch on the rear of the unit to the ON position. The intelligent touch screen control panel will illuminate.
- Program Selection and Setting:
- The control panel features an intuitive interface. Use the touch screen to navigate through the menus.
- You can select between single-curve mode or double-curve mode. The double-curve mode is specifically designed for a complete crystallization process for glass ceramics.
- Set your desired temperature, holding time, heating rate (up to 100°C/min), and vacuum level (0-80%). The furnace supports 99 programmable custom configuration files.
- The ultra-precise temperature control system maintains actual temperature fluctuation within ±1°C.
- Loading Materials:
- Carefully open the furnace door using the handle.
- Place your materials inside the chamber. Ensure they are suitable for high-temperature processing and do not exceed the chamber dimensions (3.1"x3.1"x1.9").
- Close the furnace door securely and ensure the safety door latch is engaged. The furnace will not start heating if the door is not properly closed.
- Starting the Process:
- Once the program is set and the door is closed, press the START button on the control panel.
- The furnace will begin its rapid heating cycle. The built-in vacuum pump will activate if a vacuum level is set, creating an environment up to -90kPa (80%) for fine sintering.
- Monitoring and Completion:
- Monitor the process via the control panel.
- Upon completion of the program, the furnace will signal the end of the cycle.
- Allow the furnace to cool down sufficiently before attempting to open the door and retrieve materials. Use heat-resistant gloves.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your furnace.
- Cleaning:
- Always ensure the furnace is powered off and completely cooled before cleaning.
- Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Carefully clean the interior chamber to remove any residue or debris. Use a soft brush or vacuum cleaner for loose particles. Avoid scratching the internal surfaces.
- Heat Emission Holes:
- Periodically check the heat emission holes on the rear and sides for any dust or obstructions. Clean them gently to ensure proper airflow and prevent overheating.
- Door Seal:
- Inspect the furnace door seal for any signs of wear or damage. A compromised seal can lead to heat loss and affect vacuum integrity. Replace if necessary.
- Vacuum Pump:
- While the vacuum pump is built-in, ensure its intake/exhaust ports are clear. Refer to specific pump maintenance guidelines if available in a separate document.
