Operating Instructions

1. Preparing Milk for Frothing

For best results, use cold milk. Fill your cup or pitcher with the desired amount of milk. Do not overfill, as milk volume will increase significantly during frothing.

2. Frothing Process

  1. Submerge the frother head into the milk, ensuring it is fully immersed but not touching the bottom of the container.
  2. Press the Power Button to start frothing.
  3. Adjust the speed using the Speed Lever: push up for fast speed (10,000 r/min) or push down for slow speed (8,000 r/min).
  4. Move the frother gently up and down, keeping the whisk just below the surface to incorporate air, then deeper to create a consistent texture.
  5. Froth until the milk reaches your desired consistency and volume. This typically takes 15-30 seconds.
  6. Press the Power Button again to stop the frother.

3. Using the Smart Silicone Ring

The included silicone ring can be used for hands-free frothing or as a stand.

  • Hands-Free Frothing: Slide the silicone ring onto the frother body and adjust its height to rest on the rim of your cup or pitcher. This allows the frother to operate independently while you prepare other ingredients.
  • Stable Stand: After use, the silicone ring can be positioned to allow the frother to rest horizontally, keeping the whisk head elevated and clean.
