Operating Instructions
The Spacekey Milk Frother offers four distinct functions: Hot Dense Foam, Hot Airy Foam, Cold Foam, and Milk Heating.
General Operation:
- Pour milk into the pitcher. Observe the MAX and MIN fill lines inside the pitcher.
- For frothing (Hot Dense, Hot Airy, Cold Foam): Do not exceed the lower MAX line (150 ml / 5 oz).
- For heating (Milk Heating): Do not exceed the upper MAX line (300 ml / 10.1 oz).
- Ensure milk is above the MIN line (100 ml / 3.4 oz) for frothing.
- Place the lid securely on the pitcher.
- Place the pitcher onto the power supply base.
- Press the power button once to activate the frother. The indicator lights will illuminate.
- Select your desired mode by pressing the power button repeatedly until the corresponding light is illuminated.
- The frother will automatically shut off when the process is complete.
Specific Modes:
1. Hot Dense Foam (for Cappuccinos)
Use the spring paddle. Fill milk up to the lower MAX line (150 ml / 5 oz). Press the power button once to select this mode (red light for dense foam). The frother will heat and froth milk to a rich, dense consistency.

4. Milk Heating
Remove the spring paddle and use only the heating paddle (flat whisk). Fill milk up to the upper MAX line (300 ml / 10.1 oz). Press the power button to select this mode (red light for milk heating). The frother will warm the milk to approximately 140°F (60°C) without frothing.

Maintenance and Cleaning
Proper cleaning ensures the longevity and optimal performance of your Spacekey Milk Frother.
- Immediate Cleaning: After each use, unplug the frother and allow it to cool down.
- Rinse Interior: Rinse the interior of the pitcher with warm water. Use the provided cleaning brush to gently scrub any milk residue. The non-stick coating makes cleaning easy.
- Wipe Dry: Wipe the interior and exterior of the pitcher with a soft, damp cloth. Ensure all parts are completely dry before storage.
- Paddles and Lid: Wash the paddles and lid with warm soapy water, rinse, and dry.
- Important: Do not immerse the power supply base or the bottom of the pitcher in water. This can damage the electrical components. The frother is not dishwasher safe.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Frother does not turn on. | Not properly connected to power base or outlet. | Ensure the pitcher is correctly placed on the power base and the power base is securely plugged into a working outlet. |
| Milk not frothing or heating properly. | Incorrect paddle used, milk level too high/low, or type of milk. | Ensure the correct paddle is installed for the desired function. Check milk levels against MAX/MIN lines. Whole milk (fat content >3%) is recommended for best frothing results. |
| Burnt smell or residue. | Milk residue left from previous use or overheating. | Clean the pitcher thoroughly after each use. The built-in heating paddle and non-stick coating help prevent burning, but ensure proper cleaning. |
| Frother stops unexpectedly. | Automatic shut-off activated or overheating protection. | This is normal operation. The frother automatically shuts off when the cycle is complete or if it detects overheating. Allow it to cool down before next use. |
