2. Placement: Position the oil bath on a stable, level, and non-combustible surface, ensuring adequate clearance (at least 10 cm) on all sides for ventilation.
3. Power Connection: Connect the unit to a grounded power outlet (230V, 50/60Hz) using the provided power cord. Ensure the power supply matches the unit's requirements.
4. Filling the Bath: Fill the working chamber with a suitable heat transfer oil. Ensure the oil level is between the minimum and maximum fill lines, typically covering the heating elements. Do not overfill.

Operating Instructions

1. Power On: Press the main power switch, usually located on the control panel or rear of the unit. The display will illuminate.
2. Setting Temperature: Use the control panel buttons to set the desired operating temperature. Refer to the specific control panel interface for detailed instructions on navigation and value adjustment.
3. Heating Process: The unit will begin heating the oil to the set temperature. The display will show both the set temperature and the current actual temperature.
4. Monitoring: Monitor the oil level and temperature during operation. The unit features visual and acoustic signals for low fluid levels or overtemperature conditions.
5. Power Off: To switch off the unit, press the main power switch. Allow the oil to cool down before handling.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Memmert ONE 22-230V oil bath.

• Cleaning: Disconnect from power. Allow the unit to cool completely. Drain the oil. Clean the working chamber and exterior surfaces with a mild detergent and a soft cloth. Do not use abrasive cleaners or solvents.
