• Never touch the power plug with wet hands.
• Do not immerse the ONO and the power cable in water.

3 Preparation and Commissioning

Do not place the ONO and its individual parts in the dishwasher.

Before cleaning, remove the power plug from the socket. Always wipe the ONO with a damp cloth, never wet, and protect it from constant spray water. The ONO must not be cleaned with a water jet.

The ONO is not suitable for placement on a surface where a water jet could be applied.

Setting up the Appliance:

Observe the following points when setting up your ONO:

• Place the ONO on a horizontal surface that is resistant to water.
• Choose the location for your ONO so that it is protected from overheating.

First Commissioning:

WARNING: Risk of electric shock if operated with a damaged power cable.

• Never operate an appliance with damage or a damaged power cable.

CAUTION: Milk, carbonated mineral water, or other liquids can damage the water tank or the appliance.

Stand-by and "Ready" Mode:

As soon as the ONO is connected to the mains via the power plug, it is in stand-by mode. Press one of the buttons [function button], [espresso button] or [coffee button] to switch on the ONO. If the [espresso button] or [coffee button] lights up, your ONO has heated up and is ready.

Rotary Dial Positions and Operation:

• "Filling Position": In this position, fill the ground coffee into the insert funnel. When not in use, place the rotary dial in this position.
• "Brewing Position": In this position, pull the release lever and press the rotary dial down to press the ground coffee.

The rotary dial may only be pressed down in the "Brewing Position". Do not move the rotary dial while the pump is running.

Using Ground Coffee:

• Use exclusively (freshly) ground coffee, not beans or instant coffee.
• Never fill more than two level measuring spoons of ground coffee.
• Very finely ground coffee can clog the system and the coffee will only drip through slowly. In this case, use coarser ground coffee.

Filling the Water Tank:

If the [water tank symbol] appears during preparation, you can fill and reinsert the water tank within 5 minutes. Then press the [function button] to confirm. Coffee preparation will continue.

Espresso and Coffee:

Example: Coffee

Prerequisite: The rotary dial is in the "Filling Position".
