- This User Manual
4. Setup
Follow these steps to set up your radiator for first use:
- Placement: Place the radiator on a firm, level surface in the room you wish to heat. Ensure there is at least 1 meter of clear space around the top and sides of the radiator for proper air circulation. This model is suitable for rooms approximately 24-28 m².
- Power Connection: Plug the power cord directly into a grounded 220V-240V AC electrical outlet. Do not use extension cords or power strips.
- Initial Odor: It is normal for the radiator to emit a slight odor during its first few hours of operation. This is due to the burning off of manufacturing residues and will dissipate quickly. Ensure the room is well-ventilated during this period.

5.1 Powering On/Off
- To turn the radiator on, ensure it is plugged in and press the power button on the control panel. The digital LED display will illuminate.
- To turn the radiator off, press the power button again.
5.2 Adjusting Heat Settings
The radiator offers 3 heat settings to suit your comfort needs:
- Low: For gentle, continuous warmth.
- Medium: For moderate heating.
- High (2000W): For rapid heating of larger spaces.
Use the dedicated button or rotary knob on the control panel to cycle through these settings.
5.3 Using the Mechanical Thermostat and Digital LED Display
- The digital LED display shows the current room temperature and your set temperature.
- Rotate the thermostat knob to set your desired temperature. The radiator will automatically turn on and off to maintain this temperature.
- The Mill Heat Boost Technology ensures that the hot air rises through the fins more rapidly, leading to faster and more efficient heat distribution once the desired temperature is set.
5.4 Day/Night Program
The Day/Night program allows you to set different temperatures for day and night periods, optimizing energy consumption by up to 25%.
- Consult the detailed instructions in the full manual (if available) or on the manufacturer's website for specific programming steps for the Day/Night function.
- Typically, you will set a higher temperature for the 'Day' period and a lower, energy-saving temperature for the 'Night' period.
6. Maintenance
Regular cleaning and proper storage will ensure the longevity and efficient operation of your radiator.
- Cleaning: Always unplug the radiator and allow it to cool completely before cleaning. Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents. Do not immerse the radiator in water.
- Storage: If storing the radiator for an extended period, ensure it is clean and dry. Store it in a cool, dry place, preferably in its original packaging, to protect it from dust and damage.
7. Troubleshooting
If you experience issues with your radiator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator does not turn on. | Not plugged in; power outlet not working; power button not pressed; tip-over switch activated. | Ensure plug is fully inserted. Test outlet with another device. Press power button. Check if radiator is upright on a stable surface. |
