4. PRACTICAL ADVICE

IMPORTANT!

Before first use, after prolonged periods of non-use or after descending, the appliance must be cleaned as described in the paragraph: "FIRST USE"

Remember to release the filter holder while pressing the "EJECT" button lightly before removing it from the appliance (fig. 1a).

To obtain an espresso with an intense aroma, we recommend that you use freshly ground special espresso coffee that is suited to the delicate preparation of this type of coffee, as well as cups that are not bigger than 50ml
- Keep the ground coffee in the refrigerator, it will conserve its aroma for longer.
- Do not fill your filter holder to the top, use the measuring spoon (1 spoonful for 1 cup, 2 spoonfuls for 2 cups). Remove any excess ground coffee from

the edge of the filter holder.

• If the appliance is not used for more than 5 days, empty and rinse the water tank.
• Before removing the tank to fill or empty it, always remember to switch off the appliance.
• Always ensure that the appliance is placed on a flat, stable, heat-resistant surface.

5. FIRST USE

Rinsing before first use

Before using your coffee machine, clean all of the accessories in water and washing up liquid then dry them.

• Fill the tank with cold water and fit it onto the appliance, ensuring that it is fitted correctly (fig. 1b).
• Switch on the appliance by pressing the ON/OFF button d2 ①.
• The temperature light flashes then remains lit. The appliance is ready for use (fig. 2).
• Insert the filter holder (without ground coffee) into the appliance: turn it towards the right as far as possible (fig. 3).
• Place a container with a volume of over 12 litre under the filter holder. Turn the switch d1 to the "coffee" position (fig. 4, 5, 6), then press on the two cup position several times if necessary.
• If the water doesn't run off (pump priming), repeat the process from the beginning.
• Let the water run from the tank. To stop the flow of water, turn the selector d1 to the position loq (fig. 7) and unplug the appliance.
• Remove the tank, empty it and rinse it carefully and fit it back onto the appliance (fig. 1b and 8).

6. PREPARING AN ESPRESSO

IMPORTANT!

If the espresso machine is being used for the first time, the appliance must be cleaned as described in paragraph 5 "FIRST USE".

With ground coffee

The type of ground coffee that you use will determine the strength and taste of your espresso: the finer your coffee is ground, the stronger the espresso.

• Before removing the removable tank, place the selector d1 in the position (fig. 7).
• Fill the tank with cold water and fit it back onto the appliance (fig. 8).

• Switch on the appliance by pressing the ON/OFF button d2 ①.

• The LED flashes while the machine is warming up, then remains lit. The appliance is then ready for use.

• Release the filter holder by pressing the button lightly and turning it towards the left (fig. 9). Using the measuring spoon, place the ground coffee into the filter holder: one measuring spoon (filled to the top) per cup for a good espresso (fig. 10a).
• Remove the excess ground coffee from the edge of the filter holder (fig. 10b).
• Insert the filter holder into the appliance tightening it by turning it towards the right as far as possible (fig. 12).
• Place a cup on the grill of the drip tray under the filter holder (fig. 13).
• Turn the selector d1 to the position (coffee) (fig. 4).
• Press either the d3 button for 1 cup or the D4 button for 2 cups.
  After a few moments, the coffee stars to flow.
• When the cups are full, the coffee stops flowing automatically. Move the selector d1 back to the position (fig. 7).
• Remove the cup.
• Release the filter holder: press the button lightly while turning the filter holder towards the left and remove it from the appliance. Throw away the used coffee using the ejection system by pressing the "push" button on the handle fully (fig. 16). Wash the filter holder under running water, while pressing the "push" button to eliminate the remains of ground coffee (see also paragraph 8.B for deeper cleaning). It is normal that each time the control selector d1 returns to the position [m] there is a low noise of running water or steam, due to a specific device which eliminates the pressure from the circuits.

With an E.S.E espresso pod

"ESE" for "Easy Serving Espresso" is a pod (44 mm in diameter) of 7g of coffee that has been selected, ground and compacted between two filter papers especially designed to make Italian style espresso ("ristretto" short coffee). This system permits easy, simple, clean and comfortable use of your machine.

• Before removing the removable tank, remember to place the selector d1 in the position (fig. 7).
• Fill the tank with cold water and fit it back onto the appliance (fig. 8).
• Switch on the appliance by pressing the ON/OFF button d2 ①.

• The LED flashes during preheating, then remains lit.
  The appliance is then ready for use.

• Release the filter holder by pressing the button lightly and turning it towards the left (fig. 15). If required, remove the paper around the pod following the dotted lines (fig. 11). Place the E.S.E pod with the red writing facing downwards (fold the corners of the filter paper back). Ensure that the paper is placed inside the filter, otherwise this could cause leaks. For creamier and thicker froth, the E.S.E pod must be positioned correctly. The pod is designed to make one cup of coffee. The use of 2 E.S.E pods on top of one another is not recommended.

• Insert the filter holder into the appliance tightening it by turning it towards the right as far as possible (fig. 12).
  To prepare your espresso, follow the same procedure as for the preparation of an espresso with ground coffee.

With a soft pod

Your machine is also compatible with soft pods (generally 60~mm in diameter). As this type of pod is not specifically designed for espresso machines, you will obtain a weaker espresso than with an E.S.E. pod.

• Before removing the removable tank, remember to place the selector d1 in the position loq (fig. 7).
• Fill the tank with cold water and fit it back onto the appliance (fig. 8).
• Switch on the appliance by pressing the ON/OFF button d2 ①.
• The LED flashes during preheating, then remains lit. The appliance is then ready for use.
• Release the filter holder by pressing the button lightly and turning it towards the left (fig. 15). Place a soft pod into the filter holder. The pod is designed to make one cup of coffee. The use of 2 pods on top of one another is not recommended.
• Insert the filter holder into the appliance tightening it by turning it towards the right as far as possible (fig. 12).
  To prepare your espresso, follow the same procedure as for the preparation of an espresso with ground coffee.

7. INDIVIDUAL PROGRAMMING OF THE VOLUME OF COFFEE:

To change the pre-programmed amount of water, proceed as follows:

• Fill the water tank and turn the machine on (fig. 1 abc, 2, and 4).
• Put a spoonful of coffee in the filter by using a measuring spoon or use an E.S.E. or soft pod.

EN

• Put the filter holder in place and lock it by turning it to the right as far as it will go, up to the stop (fig. 12).
• Place a cup under the filter holder.
• Hold down the "1 cup" button (>3 sec) until the "1 cup" light flashes quickly. The coffee flows out.
• When the desired amount of espresso is obtained, press the "1 cup" button. This amount will be saved automatically.
• The next time when you press the "1 cup" button, you will obtain the most recently recorded amount. Programming for 2 cups uses the same method, by pressing the "2 cups" button (>3 sec).
• If you turn off the device, the volumes will need to be reprogrammed the next time you use it.

8. STEAM FUNCTION

Steam is used to foam milk (for example to make a cappuccino).

To produce steam, turn the switch d1 to the position (fig. 17) (to obtain more steam, the temperature needs to be higher than when making coffee).
- The ON/OFF button LED flashes again then remains lit. The appliance is then ready for use.
- Put the milk into a container. For best results, we recommend you use a container with a small opening (small jug for example).
- Plunge the steam nozzle into the liquid.
- Turn the switch d1 to the position m (steam) (fig. 18): the steam comes out into the milk.
In order to give the milk plenty of froth, move the appliance in a circular direction from top to bottom (fig. 19), making sure that the steam nozzle remains upright at the centre of the container. (figs. 21c). The pump operates intermittently, this is normal.
- To obtain a good froth on your milk, we recommend that you use fresh cold pasteurised semi-skimmed milk, skimmed milk or UHT milk.
- During operation, it is normal for the temperature light of the ON/OFF button to light up and then extinguish.
- When frothing is completed, stop the appliance device (switch d1 in position).
- When the selector d1 is in the position , the appliance cools down automatically. During the cooling down phase, the LED of the ON/OFF button flashes, and hot water runs into the drip tray. When the optimal temperature for preparing an espresso is reached, the LED remains lit.

IMPORTANT!

Once the steam has been stopped, clean the steam nozzle immediately and thoroughly using a damp sponge (to avoid residues from sticking) and let a little more steam run through into free air to rinse the inside of the nozzle.

WARNING!

The steam nozzle is still hot! Be careful not to burn yours

9. MAINTENANCE AND CLEANING

A. The appliance

• Unplug the machine each time before cleaning and leave the appliance to cool down.
• Clean the outside of the appliance from time to time with a damp sponge. Wash the tank, the drip tray and its grill regularly and dry them.
• Rinse the inside of the tank regularly.
• When a fine white film obscures the tank, carry out a descaling operation. (see paragraph 10. DESCALING).
• Do not use alcohol or solvent based cleaning products.
• Once the appliance has been unplugged, clean the hot water grill and the seal regularly, using a damp sponge (fig. 16).
• Only clean with a damp cloth, do not use detergents or abrasive products.

B. The filter holder

The appliance that you have purchased is equipped with a removable ejecting filter holder, which allows you to maintain it in perfect working order. We recommend that you clean it each time after use.

These removal/fitting operations must be carried out when the machine has cooled down.

1. Removal of the filter holder:

2. Remove the filter holder from your machine.

3. Dispose of the used coffee or pod by pressing the "push" button (fig. 16).
   Rinse in clear water.
4. Remove the back of the filter holder by turning to the left, while pressing in the two brackets.

2. Cleaning and rinsing the filter holder:

The filter holder may then be cleaned using a household detergent and a scouring pad, but must be rinsed afterwards in clear water. For best results, you may press the ejection button several times while rinsing. We recommend shaking your filter holder vigorously in order to remove all water.

3. Fitting the filter holder:

Replace the bottom of the filter holder by rotating it anti-clockwise to lock.

C. The drip tray

When the drip tray full level is displayed, it must be emptied after removing the grid (fig. 20). The presence of water is normal, and does not mean there is a leak. If necessary, clean the drip tray and its grid with water and a little gentle washing-up liquid. Rinse and dry.

D. The steam nozzle (Fig 21 a, b)

This accessory consists of 2 parts: one part which is the plastic support and the other which is the metal protection cylinder.

• Before cleaning, unlock the nozzle from the articulated arm by turning it to the left.
• Then slide the metal cylinder along the plastic support.
• Clean these two parts with tap water and some mild washing-up liquid.
• Rinse and dry.
• Once the parts have been properly cleaned, put the metal cylinder back on the support.
• Make sure that you don't damage the silicone seal which makes the nozzle watertight.
• Insert the nozzle on the articulated arm then twist to the right.

10. DESCALING

• Regular descending of your appliance, as mentioned in paragraphs A and B for the coffee and steam functions, is the best guarantee of your machine's long life. The frequency of the descending operations must be adapted to suit the hardness of your water. Ask for advice from your local water authority.
• During the operation, do not stand your appliance on a marble surface. The descaler could affect it.
• To make this clearer, please find below a summary table of the frequencies of the descending operations according to the hardness of water and use:

DESCALING FREQUENCY
Av. number of coffees per week	Soft water (<19°Cth)	Hard water (19-30°Cth)	Very hard water (>30°Cth)
Less than 7	Once a year	Every 8 months	Every 6 months
From 7 to 20	Every 4 months	Every 3 months	Every 2 months
More than 20	Every 3 months	Every 2 months	Every month

If in doubt, we recommend carrying out a descending operation every month.

No repairs to your machine will be carried out due to:

• descending not being carried out,
• scale.
