4. Setup

4.1 Unpacking and Inspection

• Carefully remove the oven from its packaging.
• Inspect the unit for any visible damage incurred during transit. Report any damage to the carrier immediately.
• Verify that all accessories and components listed in the packing list are present.

4.2 Placement

• Place the oven on a stable, level, and non-combustible surface.
• Ensure there is adequate clearance (at least 10-15 cm) around all sides of the oven for proper ventilation and heat dissipation.
• Avoid placing the oven near heat sources, flammable materials, or in direct sunlight.
• The operating environment should be free from corrosive gases and excessive dust.

4.3 Electrical Connection

• Confirm that the local power supply voltage matches the oven's requirements (220V or 380V, depending on the model).
• Connect the oven to a dedicated, properly grounded electrical outlet. Do not use extension cords or adapters.
• Ensure the power cord is not damaged, pinched, or routed through high-traffic areas.

5. Operation

5.1 Initial Power-On

• After ensuring proper setup, turn on the main power switch.
• The display (if digital) or pointer (if analog) will illuminate.

5.2 Setting Temperature (Digital Controller)

• Press the "SET" button to enter temperature setting mode.
• Use the up/down arrow buttons to adjust the desired temperature (SV value).
• Press "SET" again to confirm and exit the setting mode. The oven will begin heating to the set temperature.

5.3 Setting Temperature (Pointer Controller)

• Rotate the temperature knob to the desired temperature indicated on the dial.
• Ensure the "POWER" and "HEAT" switches are in the ON position.
• The oven will begin heating to the set temperature.

5.4 Loading Samples

• Once the oven reaches the desired temperature, carefully open the door.
• Place samples evenly on the shelves, ensuring not to overload or block the airflow.
• Close the door securely.

5.5 Monitoring and Completion

• Monitor the internal temperature via the display or pointer.
• Use the double-layer glass observation window to check on samples without opening the door.
• Once the drying process is complete, turn off the heating element and allow the oven to cool down before carefully removing samples.

6. Maintenance

6.1 Cleaning

• Exterior: Wipe the exterior surfaces with a soft, damp cloth and mild detergent. Avoid abrasive cleaners.
• Interior: For the stainless steel interior, use a non-abrasive cleaner. Ensure all cleaning agents are thoroughly rinsed and dried before next use.
• Glass Window: Clean the observation window with a glass cleaner.
• Always ensure the oven is cool and disconnected from power before cleaning.

6.2 Regular Checks

• Door Seal: Periodically inspect the high-temperature resistant silicone door seal for any signs of wear, cracks, or damage. A damaged seal can lead to heat loss and inefficient operation.
• Electrical Cord: Check the power cord for fraying or damage.
• Ventilation: Ensure the vent holes are clear of obstructions.
• Shelves: Clean and inspect shelves for any residue or damage.
