Page 3: Making Espresso
Summary Making Espresso Start the machine Push the power switch (1) to the right, and let it return to the middle position by loosening it. Connect the empty portaﬁlter immediately to the brew group (5). The machine and portaﬁlter will warm up now. After about 12 minutes the machine will be warm when only the top light indicator is on.

You can put the machine back in the original mode by repeating this procedure again. (1) You can also use the main power switch at the bottom of the Xenia to “disconnect” the Xenia from the mains supply  ...
Page 8 machine parts 2: Extraction Switch Single extraction Push the switch to the right, and let it return to the middle position. A 30 second extraction will start; the ﬁrst 5 seconds are to start up the pump slowly, then 25 seconds for coffee extraction.
Page 9 machine parts 3 - 4: Levers 3: Hot Water Lever Press the toggle lever either upward of downward to draw boiling water out of the boiler, for example to warm up the cups before an extraction. As the water is boiling, the water will have bubbles when it comes out.
Page 10: Brew Group
machine parts 5: Brew Group The brew group is the central entity that connects the portaﬁlter holder containing the coffee grind. The ﬁlter holder should be turned approx. 45° to the left, inserted with the wings in the brew group, and ﬁnally clamped counter-clockwise (the brew group can slightly move in the clamping direction).
Page 11 machine parts 6 - 7: Gauges 6: Boiler pressure gauge About 3 minutes after the start of the machine, you can hear a slight hissing and from the drain left down in the front some steam and water comes out. After a short time this ends and the pointer of the boiler pressure gauge on the left starts to move in a clockwise direction to approx.

machine parts 8: Signal indicators Machine On (default colour: white) The upper light indicates when the machine is enabled. It is off when the machine is stand-by or switched off by the main power switch at the bottom of the machine. Brew Group Heating (default colour: orange) Indicates when the brew group is heated.
Page 13 When sliding back the panel, be careful not to apply too much force at the end to prevent scratching the Xenia front housing. With an optional cup elevation, cups can be brought 3 cm closer to the portaﬁlter spout, to prevent spilling of coffee ﬂuids to the outer wall of the cups...
Page 14: Water Tank
machine parts 10: Water Tank The 2.4 liter water tank is the source of water for hot water, steam and coffee. It can be reached from the top (12) or from the side (10). The tank should be positioned correctly towards the sensor (on the right side at the back of the machine, see sticker), otherwise the machine assumes there is no water in the tank.

The Xenia espresso machine is a household machine that can be used to make espresso, cappuccino and similar drinks in conjunction with a suitable grinder. Professional use of the machine is not foreseen. INSTALLING Get GOING As with all devices connected to the mains and with heaters or a pressure vessel, care must be taken to avoid injury.

The original packaging (with the pads) should be kept for future use, as this special taken when using it to avoid injury. Therefore, you must read this manual thoroughly before packaging provides the best protection against impact during transport.
Page 19 installing Safety Notes: HEAT Caution: The red coloured parts of the machine may become very warm Caution: Steam is very hot and you have to make sure that you open the valve during operation or a long while after the machine has been turned only when the nozzle is immersed in milk so that you or other people off.
Page 20 installing Unpacking For unpacking, carefully cut the four corners sides. When cutting the carton or the adhesive strips, make sure that the knife does not dive too deep into the carton, otherwise the machine may be damaged. The original packaging (with the pads) must be kept for future use as this special packaging provides the best protection against impact during transport.

Page 23 USE CASES Starting UP Start up the machine by pull the power switch to the right side. The signal indicators will go on. The machine will be ready in ~13 minutes.  In the meantime, check if the drip tray is empty and clamp the portaﬁlter to the brew group (without coffee grind) so that it warms up together with the machine.
Page 24: Preparing Coffee
Use Cases Preparing Coffee After starting and heating up the machine, an extraction can be started. Depending on the amount of coffee required, a single or dual extraction can be started with the extraction switch. After the portaﬁlter is ﬁlled with ground coffee and tamped with a tamper, the ﬁlter holder should be clamped in the machine as soon as possible.
Page 25: Foaming Milk
For correct milk foaming hold the steam wand diagonally into the milk just below the surface (about 0.25 l for a 0.5 liter jug). Since the Xenia has no rigid steam wand, that's pretty easy. The goal is to mix only slightly sipping air under the milk when frothing.
Page 26: Pre-Heating Cups
Use Cases Pre-Heating cups The cup holder on top of the Xenia can be used to pre-heat coffee cups. It is With the hot water lever you can open the valve to the boiler to extract boiling heated by the radiation of the boiler inside the machine.
Page 27: Cleaning And Maintenance
When the brewing pressure has reached 8 bar, Xenia front housing. terminate the extraction by pushing the extraction switch. Water will leave the drain (followed by steam).
