Operating Instructions
The NWOUIIAY Electric Milk Frother offers 4 modes for various milk preparations. Always ensure the frother is on its power base before operation.

Image Description: This image illustrates the different modes of the milk frother. For "Hot Milk Foam" and "Cold Milk Foam", the maximum capacity is 160ml, with completion times of 80-120 seconds and 65 seconds respectively, both reaching approximately 65°C. For "Hot Milk" (without frothing), the maximum capacity is 350ml, with a completion time of 120-160 seconds, also reaching approximately 65°C.

Image Description: An internal view of the frother jug with clear measurement markings. It shows a "MAX: 350ML" line for heating milk, a "MAX: 160ML" line for frothing milk, and a "MIN: 100ML" line for the minimum filling level. These lines are crucial to prevent spillage and ensure proper operation.
General Operation Steps:
- Pour the desired amount of milk into the frother jug. Observe the internal MAX/MIN fill lines:
- MAX 160ml: For frothing milk (hot or cold foam).
- MAX 350ml: For heating milk without frothing.
- MIN 100ml: Minimum filling level for all operations.
- Place the lid securely on the frother jug.
- Press the On/Off button once to turn on the frother. The indicator lights will illuminate.
- Press the On/Off button repeatedly to cycle through the available modes. Each press will select a different mode, indicated by the corresponding light.
- Once the desired mode is selected, the frother will begin operation.
- The frother will automatically shut off when the process is complete, and the indicator lights will turn off.
- Carefully remove the lid and pour the frothed or heated milk.
Specific Modes:
- Hot Milk Foam (Thick/Thin): Use the frothing whisk (with spring). Fill milk up to the 160ml MAX frothing line. Select the appropriate hot foam mode. The milk will be frothed and heated to approximately 60°C (140°F) in 80-120 seconds.
- Cold Milk Foam: Use the frothing whisk (with spring). Fill milk up to the 160ml MAX frothing line. Select the cold foam mode. The milk will be frothed without heating in approximately 65 seconds.
- Hot Milk (No Foam): Remove the spring from the whisk or use the whisk without the spring (if provided). Fill milk up to the 350ml MAX heating line. Select the hot milk mode. The milk will be heated to approximately 60°C (140°F) in 120-160 seconds.
Note: For best results, use cold milk (around 4-6°C) and ensure the frother jug is clean and dry before each use.
