Setup
- Prepare Your Cup: Ensure your compatible WACACO insulated cup (Octaroma, Cuppamoka, or Pipamoka) is clean and ready for use.
- Open the Lid: Before attaching, press the push-button on the EXAFLOW lid to the open position. This is crucial for proper sealing and function.
- Attach the Lid: Carefully screw the EXAFLOW lid onto your insulated cup until it is securely fastened. Do not overtighten.
- Fill the Cup: Pour your desired hot water or beverage into the cup. Important: Never overfill the cup. The maximum fill level is 1 cm (½ inch) below the step line inside the cup.


Operating Instructions
General Use (Drinking):
- Open: Press the central button on the lid to open the drinking spout.
- Drink: Tilt the cup and drink directly from the spout. The integrated handle provides a comfortable grip.
- Close: Press the central button again to close the spout, ensuring a leak-resistant seal.

Pour-Over Coffee Preparation:
The EXAFLOW lid is ideal for precise pouring during pour-over coffee brewing.
- Heat Water: Heat water to your desired brewing temperature.
- Fill EXAFLOW: Pour the hot water into your compatible WACACO cup with the EXAFLOW lid attached (ensure the lid button is in the open position before filling).
- Prepare Pour-Over Setup: Place your pour-over dripper and filter onto your serving vessel or another compatible WACACO cup (e.g., Cuppamoka).
- Pour: Use the EXAFLOW lid's precision spout to slowly and steadily pour hot water over your coffee grounds. The controlled flow mimics a gooseneck kettle, allowing for even saturation.
