2. Place the machine on a sturdy, level, and heat-resistant countertop or stand. Ensure there is adequate ventilation around the machine.
3. Ensure the power outlet is easily accessible and matches the machine's voltagrequisits electrònics (230 volts).

4.2 Boiler Filling

1. Ensure the machine is unplugged from the power outlet.
2. Locate the manual boiler water charge button.
3. Fill the boiler with fresh, filtered water using the designated filling method (refer to specific instructions in your machine's full manual for exact filling port location if not using the manual charge button for initial fill). For initial setup, it is crucial to fill the boiler to the appropriate level indicated by the sight glass.
4. Do not overfill the boiler. The water level should be visible within the sight glass, typically between the minimum and maximum marks.

4.3 Power Connection and Initial Heat-Up

1. Connecteu la màquina a una presa de corrent elèctrica amb terra.
2. Turn on the main power switch (usually located on the front or side of the machine).
