Setup
- Install Batteries: The NanoFoamer V2 requires 2 AA batteries (not included). Unscrew the bottom cap of the frother and insert the batteries according to the polarity indicators. Securely reattach the cap.
- Attach NanoScreen: Select either the Fine or Superfine NanoScreen based on your desired foam texture. Align the NanoScreen with the impeller shaft and click it into place.
- Prepare Milk: Heat your milk to approximately 60 degrees Celsius (140 degrees Fahrenheit). Avoid exceeding 70 degrees Celsius (158 degrees Fahrenheit) as this can break down milk proteins and affect frothing quality. Ensure you have at least 3.8 cm (1.5 inches) depth of milk in your frothing jug for optimal results.

Operating Instructions
Follow these steps to create microfoamed milk:
- Choose NanoScreen: For beginners, the Fine NanoScreen is recommended as it is easier to achieve good results. The Superfine NanoScreen produces thinner microfoam.
- Churn Milk: Submerge the NanoFoamer V2 into the warm milk. Press the digital on/off switch to activate. Start in the middle of the milk to incorporate air, then move the frother towards the side of the jug for a perfectly consistent blend. Continue for approximately 20-30 seconds.
- Pour: Once the desired microfoam consistency is achieved, turn off the NanoFoamer V2. Gently swirl the milk in the jug to homogenize the foam before pouring it over your espresso or coffee.

Maintenance & Cleaning
The NanoFoamer V2 is designed for easy cleaning:
- Rinse After Each Use: Due to its IP4 waterproof rating, you can rinse the frother directly under running water immediately after each use. This prevents milk residue from drying and becoming difficult to remove.
- Remove NanoScreen: Periodically remove the NanoScreen and impeller for a more thorough cleaning. Wash them with warm, soapy water and rinse thoroughly.
- Storage: After cleaning and drying, place the protective hood over the impeller and NanoScreen. You can store your NanoFoamer V2 in a drawer or use the adhesive wall mount for convenient access.

Troubleshooting
- Poor Foam Quality:
- Ensure milk is at the correct temperature (around 60°C).
- Verify sufficient milk depth (at least 3.8 cm).
- Check that the NanoScreen is correctly attached and not damaged.
- Replace batteries if the frother's speed seems low.
- Frother Not Turning On:
- Check battery installation and ensure they are fresh.
- Ensure the digital on/off switch is pressed firmly.
- Excessive Splashing:
- Ensure the impeller is fully submerged in the milk before activating.
- Use a taller frothing jug if necessary.
