Usage Features

Operating the Siroca STC-401 involves a series of straightforward steps designed to simplify the coffee-making process.

Preparation:
- Begin by removing the main body lid.
- Place the mesh filter securely into the basket with the mill.
- Measure the appropriate amount of coffee beans or coffee powder according to the desired number of cups and coffee type (hot/iced or mug). The manual provides a detailed table for estimated usage:
  - Hot coffee/Ice coffee:

1 cup: 12g (Bean mode 1)
2 cup: 18g (Bean mode 1)
3 cup: 24g (Bean mode 2)
4 cup: 33g (Bean mode 2)
- Mug:
1 cup: 15g (Bean mode 1)
2 cup: 24g (Bean mode 2) * Once the coffee is added, attach the main lid, ensuring it is properly seated over the water supply pipe and water inlet. * Pour water into the water supply tank. The tank has a scale indicating levels for hot, mug, and ice coffee. It is crucial to note that water should not be poured directly into the fuel tank from the faucet, and the main body should not be exposed to water. Ensure the water level is above the minimum scale but not exceeding the full scale. * Close the lid of the water supply tank. * Place the coffee server (glass container) onto the heat retention plate. * Finally, plug the power cord into an outlet. It is important to use an outlet rated 15 V / AC 100 V only.

Brewing:
- Adjust the mode selector switch to the desired setting. The mode switch offers several options:
  - Off: Terminates the brewing process.
  - Ground coffee symbol: For dripping from coffee ground.
  - Bean mode 1 (01): For dripping from coffee beans (12/15/18g).
  - Bean mode 2 (02): For dripping from coffee beans (24/33g).
- Press the start button to begin brewing.
- Important safety notes during brewing: Do not drip while the feed water tank is empty. Do not open the lid of the main unit while dripping, and keep hands or mouth away from the steam mouth.
- Once the drip is finished, a sound will be heard, and the start button light will change from flashing to steady.
Serving and Post-Brewing:
- After brewing, set the mode selector switch to "OFF".
- Carefully pour the brewed coffee from the server. Avoid touching the hot parts of the server.
- To make iced coffee: Drip coffee following the same procedure as hot coffee. Transfer the brewed coffee to another container, allow it to cool, and then refrigerate it. Once chilled, pour the drip coffee into a glass with ice.
- After use, unplug the power plug from the outlet.
- Allow the body to cool sufficiently before taking out the basket with the mill and the mesh filter.
- Discard the used coffee beans or powder.
