Always use liquid medium in the front tank. Ensure the liquid level is at least 30mm below the workboard to prevent heater damage when powered on. 2. Choose the appropriate liquid medium based on working temperature: - For 5–85°C, water is typically used. - For 85–95°C, a 15% glycerol aqueous solution is recommended. - For temperatures above 95°C, oil is preferred. The flash point of the selected oil should be at least 50°C higher than the operating temperature. 3. Power supply must be 220V 50Hz, with sufficient capacity and a reliable grounding system. 4. Place the instrument in a dry, well-ventilated area, keeping a clear space of at least 300mm around it. 5. Avoid opening the top cover when the bath is at high temperatures to prevent burns. 6. After use, turn off all switches and disconnect the power. 7. Regularly clean the work surface and control panel to maintain hygiene. 8. Monitor the liquid level in the tank regularly. If it becomes too low, replenish the medium promptly. For tanks operating above 100°C, internal circulation is required for safety. If external circulation is requested, ensure all connections are secure to avoid leaks and potential hazards.
