3. Setup

Proper setup is crucial for the safe and effective operation of your convection oven.

3.1 Unpacking and Inspection:

• Carefully remove the oven from its packaging.
• Inspect the unit for any signs of damage incurred during shipping. Contact your supplier immediately if damage is found.
• Ensure all included components are present: 1 Convection Oven, 1 English Manual.

3.2 Placement:

• Place the equipment on a dry, stable platform or ground.
• Maintain a minimum distance of 50cm (approximately 20 inches) from any walls or other obstructions to ensure proper ventilation.
• Ensure the bottom anti-slip feet are securely positioned to maintain stability and prevent scratches on surfaces.

3.3 Electrical Connection:

• Connect the power cord to a grounded electrical outlet. The oven operates on 110V, 60Hz.
• As a safety measure, install an external grounding device.
• Ensure the power supply matches the equipment's requirements and install a leakage protection device for safety.

4.3 Fan Operation:

• The oven features a fan speed control switch. Select the desired fan speed (I, II, III) or turn it OFF.
• For uniform heating and to avoid large temperature deviations, it is recommended to keep the fan running during operation, unless specific experimental conditions require it to be off.

4.4 Timing Function:

• The digital controller includes a timing function. Set the desired operation duration as per your experimental requirements.

4.5 Monitoring:

• Monitor the temperature and process through the large double-layer tempered glass observation window.
• The digital display shows current (PV) and set (SV) values.

5. Maintenance

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

5.1 Cleaning:

• Always turn off the power and unplug the oven before cleaning.
• Allow the oven to cool completely before cleaning.
• Wipe the exterior surfaces with a damp cloth and mild detergent. Avoid abrasive cleaners.
• The stainless steel lining is easy to clean. Use a non-abrasive cleaner suitable for stainless steel.
• Keep the oven dry and clean when not in use.

5.2 General Care:

• Regularly check the power cord for any signs of damage.
• Ensure the ventilation openings are not blocked.
• Inspect the silicone sealing tape for wear or damage.

6. Troubleshooting

This section addresses common issues you might encounter with your oven.

6.1 Oven Not Powering On:

• Check if the power cord is securely plugged into a functional electrical outlet.
• Ensure the main power switch on the oven is in the 'ON' position.
• Verify the circuit breaker or fuse for the outlet has not tripped.

6.2 Temperature Not Reaching Set Point:

• Confirm the set temperature is within the oven's operating range (+10-300 ℃).
• Ensure the oven door is properly closed and the silicone seal is intact.
• Check if the fan is operating correctly. The fan ensures uniform heating.
• Avoid overloading the oven, which can affect heating efficiency.

6.3 Overtemperature Alarm:

• If the overtemperature alarm activates, immediately check the set temperature and the actual temperature displayed.
• Reduce the set temperature if it is too high or if the oven is overheating.
• If the issue persists, power off the oven and contact customer support.

6.4 Uneven Heating:

• Ensure the fan is turned on and operating at an appropriate speed.
• Distribute items evenly on the racks to allow for proper air circulation.
• Avoid blocking the air vents inside the chamber.
