Tips for milk preparations
• The best results are achieved with cold, fresh cow’s milk that is not UHT sterilised.
• If you do prefer to use sterilised milk, full-fat or evaporated milk would be best. These generally result in a fuller foam with more ?avour than skimmed milk.
• Skimmed milk is easy to froth, but the foam quickly becomes too airy because the formed bubbles are large. This also causes the foam to quickly collapse, making it poor quality.
• Keep the milk tank with milk in the fridge between preparations. Avoid leaving it out too long to prevent spoiling.
Never pour leftovers from the milk tank back into the milk carton or bottle.
PREPARING HOT WATER
1. Adjust the height of the coffee spout and place a cup under the spout.
2. Press the hot water button briely.
3. The appliance will dispense 200 ml of hot water. If you need less water, press the EXIT button to stop the ?ow as soon as you have the desired amount of water. If you need more water, press the hot water button again and then the EXIT button as soon as the desired amount of water is obtained.
DUAL PREPARATION
Press the x2 button to brew two cups of coffee in succession. This can be done both prior to brewing the coffee and while the coffee is brewing. The icon will light up on the display. While lit, the appliance will always brew 2x the selected preparation in consecutive order. Press the x2 button again to turn off this function.
RINSING
1. Adjust the height of the coffee spout and place a container under the spout.
2. Press and hold the RINSE button for 3 seconds to start the rinse function of the espresso machine. This function uses about 60 mI of water and ends automatically after cleaning is completed. It is used to remove possible coffee residues in the pipes.

ADJUSTING THE GRIND SETTINGS
The grind settings can be adjusted using the dial on the coffee bean hopper
Do this only when the grinder is turning; otherwise, the grinder may get damaged.
The default setting on the dial is the coarsest setting. We recommend that you do not change this setting for the first 100 cups.
• If the coffee is dispensed too slowly during brewing (powder is too fine), turn the grind dial clockwise until the grind setting is coarser.
• If the coffee is dispensed to quickly and looks too diluted (coffee powder is too coarse), turn the grind dial counterclockwise until the grind setting is less coarse.
Tips
• Only adjust the grind settings if the coffee tastes too bitter or too sour, and all other settings (quantity of ground coffee, water volume, and water temperature) have been tested. If the appliance dispenses a nice steady stream and the flavour is balanced, no adjustment is needed.
• A coarser grind means more sour flavours. Using a finer grind produces more bitter flavours.
• Do not overfill the coffee bean hopper and don’t leave the coffee beans in the hopper for too long, so they don’t take on too much moisture and lose their freshness (especially on humid days). Moisture affects the grinding, brewing, and flavour of the coffee.
• If the coffee beans are wet, empty the hopper, dry it using a soft cloth and fill with fresh coffee beans for a better flavour. Set the grind settings to maximum first and try to grind the coffee beans. If the coffee machine is working correctly, return the dial to its original setting.
• If the coffee beans are not ground properly, the coffee beans may be too wet, or there may be too much coffee bean oil in the grinder. If the latter is the case, add grind cleaner to the coffee bean hopper and follow the instructions on the packaging of the coffee grinder cleaner.
CLEANING AND MAINTENANCE
It is recommended that steps 1-7 are carried out daily. Daily maintenance is important to extend the life of the espresso machine and achieve better results.
1. Place a cup under the spout and rinse (see “Rinsing” under “Use”).
2. Turn the appliance off and remove the plug from the socket.
3. Disconnect the milk supply hose. Clean the milk tank, lid, pipe and supply hose using warm water and a mild detergent. Rinse thoroughly under running water.
4. Remove the milk connector from the coffee spout. Rinse with the fine brush under running water.
To clean the internal milk line, you can also fill the milk tank with clean water and run it through the system using the MILK function.
5. Remove the drip tray. Empty the coffee grounds collection tray. Using clean water, clean the drip tray, the grate, the tray. Dry thoroughly.
6. Open the side panel. Remove the brewing unit by pressing the button on the side of the brewing unit and pulling the brewing unit towards you. Rinse the brewing unit thoroughly under running water and dry. Make sure all the coffee residue is removed.
Never clean the brewing unit in the dishwasher!
7. Use the cleaning brush to remove coffee residue in and around the internal ground coffee channel.
8. Clean the outside and the inside of the housing and the control panel using a soft, damp cloth.
9. Rinse the water tank under running water every 3 days.
10. Clean the coffee bean hopper weekly. Remove the leftover coffee beans from the hopper (or clean when the hopper is empty) and wipe clean using a soft cloth.
If you experience problems when grinding coffee beans, thorough cleaning of the grinder may be required. To do this, use a coffee machine grinder cleaner and follow the instructions on the packaging.
11. Place all parts back in their original position. If a part is not (properly) installed, the appliance will indicate this on the display (see ‘Indicator lights and warnings’).
