3. Remove all packing materials from inside and outside the oven chamber.

4.2 Placement

• Place the oven on a level, stable, and heat-resistant surface.
• Ensure there is at least 6 inches (15 cm) of clearance around all sides of the oven for proper ventilation.
• Locate the oven in a well-ventilated area, away from flammable materials, liquids, or gases.

5.2 Setting Temperature

1. Ensure the oven is plugged in and the main power switch is ON.
2. Refer to the specific instructions for your digital temperature controller model to set the desired temperature. Typically, this involves pressing a "SET" button and using arrow keys or a knob to adjust the value.
3. Confirm the set temperature is displayed. The oven will begin to heat up to the target temperature.

5.3 Loading Material

• Always use heat-resistant tongs or gloves when handling materials to be placed in the oven.

• Close the door securely.

5.4 Heating Process

• Monitor the digital display to track the oven's current temperature.
• The oven will cycle on and off to maintain the set temperature.
• Do not open the oven door unnecessarily during the heating process, as this will cause temperature fluctuations and energy loss.

5.5 Unloading Material and Cooling

• Once the heat treating process is complete, turn the oven OFF using the main power switch.
• Allow the oven and its contents to cool down to a safe handling temperature. This can take several hours depending on the set temperature and ambient conditions.
• Use heat-resistant gloves and tongs to carefully remove the treated material from the oven.
• Keep the oven door closed during cooling to prevent rapid temperature changes that could damage the oven or its contents.
