This document describes the Ariete 1450 automatic coffee machine.
Function Description
The Ariete 1450 is an automatic coffee machine designed to prepare coffees and cappuccinos. It also features a hot water dispensing function for teas or infusions. The appliance is intended for private, household use and is not suitable for industrial or commercial purposes.
The machine offers three operating modes: default, ECO, and fast mode. The ECO mode is designed to save energy, while the fast mode allows for quicker beverage preparation. It includes a pre-infusion feature that moistens coffee beans with a small amount of water before full extraction, increasing pressure inside the brewer for a fuller, more intense taste.
Users can select between strong or mild coffee and can program a favorite beverage setting to save a preferred coffee type and dispensed amount. The machine automatically performs internal circuit cleaning cycles upon startup (unless turned off for a short period) and after prolonged inactivity.
Important Technical Specifications
The identification data for the appliance, including manufacturer, CE marking, model (Mod.), serial number (SN), power supply voltage (V), frequency (Hz), and electrical power consumption (W), are located on a plate under the base of the appliance. This information is crucial for any service requests.
The appliance is equipped with an automatic shut-off system that activates after 10-30 minutes of inactivity, depending on the selected operating mode, to comply with energy consumption regulations.
