Carefully remove the espresso machine from its packaging. Place the machine on a stable, level, and heat-resistant surface. Ensure there is adequate space around the machine for ventilation and access to the water reservoir and drip tray.

2. Water Reservoir Filling

Remove the water reservoir from the back of the machine. Fill it with fresh, filtered water up to the maximum fill line. Reinsert the reservoir securely into its position.

3. Initial Startup and Priming

1. Plug the machine into a grounded 120V outlet.
2. Turn the main power switch to the 'ON' position. The machine will begin to heat up.
3. Once the machine reaches operating temperature (indicated by the pressure gauge), lift the brew lever on the E61 grouphead until water flows steadily from the group. This primes the pump and fills the boiler. Lower the lever once water flows consistently.
4. Open the steam wand valve briefly to release any air and allow steam to escape, then close it.

Before brewing, run a few ounces of hot water through the grouphead and steam wand to rinse any manufacturing residues. Allow the machine to heat for at least 20-30 minutes for optimal temperature stability.

2. Mmiri ara ehi na-eku ume

The Diletta Bello's heat exchanger boiler allows for simultaneous brewing and steaming.

1. Purge the steam wand by opening the steam valve briefly to release any condensed water, then close it.
2. Immerse the tip of the steam wand just below the surface of cold milk in a stainless steel pitcher.
3. Open the steam valve fully.
4. Stretch the milk by keeping the wand tip near the surface to incorporate air, creating a hissing sound.
5. Once the milk has expanded to the desired volume, submerge the wand tip deeper to create a swirling vortex, heating the milk to approximately 140-150°F (60-65°C).
6. Close the steam valve and immediately wipe the steam wand with a damp cloth. Purge the wand again to clear any milk residue.

3. Ịsa Mmiri Ọkụ

The hot water wand can be used to dispense hot water for americanos or tea. Open the hot water valve to dispense, and close it to stop.

4. Ọnọdụ Eco

The Diletta Bello features an optional 60-minute eco timer. This mode can be activated or deactivated via a switch located under the case of the machine. When active, the machine will enter a low-power state after 60 minutes of inactivity to conserve energy.
