• Place the coffee filter (C3) or (C4) in the filter holder (C1)
• Attach the filter holder (C1) complete with filter to the appliance.
• To attach correctly, align the filter holder handle with “INSERT”  then turn the handle to the right until it is aligned in the “CLOSE” position;
• Place a container under the filter holder and steam wand (A9);
• Press the OK button (B6). Delivery begins;
• When delivery has finished, press the steam button (B9)  and deliver steam for a few seconds to rinse the steam circuit. For best results, repeat 3 or 4 times.
• The purpose of this procedure is to purge any water from the circuit before using steam to prepare a beverage.

The appliance is ready for use.
Please note: We also recommend rinsing the internal circuits if the appliance is not used for a long period. The first time you use the appliance, you need to make 4-5 cups of coffee before the appliance starts to give satisfactory results. Pay particular attention to the quantity of pre-ground coffee in the filter ((C3) or (C4)) (see instructions in section “4.1 Step 1 – Grinding”). Proceed as described in the section “The “perfect dose

MAKING COFFEE

Step 1 – Grinding

• Put coffee beans in the container (A3)  It is best to grind only a quantity of beans sufficient for immediate use, so that the coffee will always be fresh.
• The default grinding setting is 5 (medium ground). If this is too fine or too coarse, adjust the level according to personal taste and the type of coffee used (adjust only when the coffee mill is in operation
• Place one of the coffee filters (C3) or (C4) in the filter holder (C1). Press (B5) to select preparation of 1 or 2 cups. This also doubles the quantity of espresso delivered.
• Set the quantity by adjusting the dial (B4), starting from the minimum position
• The first time you use it, leave the dial in the Min. position. In the beginning, it is normal to make a few attempts before finding the optimal setting.
• We suggest you start with the default values, then modify them if necessary following the suggestions in section “Adjusting the quantity of ground coffee in the filter”.
• Attach the dosing and tamping guide (C2) to the filter holder: 1 press; 2 rotate to lock
• Insert the filter holder in the coffee mill outlet (A13)
• Press the filter holder until you hear a “click” then release. Grinding starts and stops automatically

Adjusting the quantity of ground coffee in the filter
Different varieties of coffee bean give different results when ground: consequently, the initial adjustment of the dosage requires special care. This illustration shows how to regulate the dosage, based on the roast colour: this should be taken as a general guide, given that in practice, the final adjustment can vary according to the composition of the beans

• Set the quantity (to the raised mark inside the coffee filter), starting from the minimum position.
• The numbers on the dial are a handy reference to note down once the quantity in the filter is ideal.
• The numbers do not correspond to the coffee mill settings, measurement units (g/oz) or grinding time.
• Looking at the roast colour of your particular beans, turn the dial slowly to find the right adjustment

Step 2 – Tamping

• After grinding, remove the filter holder
• Tap the dosing and tamping guide (C2) to level the ground coffee.
• (Certain models only): rest the filter holder in the housing on the pressing mat (C12)
• Press the coffee using the presser (C11)
• Remove the dosing and tamping guide by turning it anticlockwise and pulling upwards and check that the quantity is correct (see “The “perfect dose””).
• Attach the filter holder to the coffee outlet (A10)

The “perfect dose”

• The perfect quantity corresponds to the raised line inside the coffee filters;
• Make sure the coffee is at the right level after tamping. It might be necessary to adjust the level a few times using the dial (B4) before the ideal dosage is achieved.
• If the coffee is extracted too strongly or too weakly even at the ideal dosage, this can be corrected by grinding the beans more finely or more coarsely (see “4.1 Step 1 – Grinding”).
• To correct over-extraction (coffee released too slowly), select a coarser setting. To correct under-extraction (coffee released too quickly), select a finer setting

Step 3 – Brewing

• Select the temperature (fig. 20) (see “Coffee preparation temperature”).
• Select the desired beverage (fig. 21). If the beverage has been programmed (see section “6. Programming beverage quantities”), the beverage light flashes briefly.
• Press OK (B6) to start brewing (fig. 22) (pre-infusion and infusion). Delivery of the coffee will stop automatically.

Coffee preparation temperature
The water temperature is controlled during the entire preparation process to ensure its stability during the extraction step. The Specialista Arte has 3 infusion temperatures* in a range between 92 and 96 °C. The temperature effectively utilized will depend typically on the variety of been and the roast: Robusta beans require a lower temperature, and Arabica beans a higher temperature. The same applies for dark roasted beans or for light roasted beans, respectively.

MAKING MILK BEVERAGES

Frothing the milk

• Fill the jug (C8) with the amount of milk to be warmed/ frothed, bearing in mind that the milk doubles or triples in volume .
  For a denser and more evenly distributed froth, best results will be achieved using whole cow’s milk at refrigerator temperature (about 5 °C

• Place the jug under the steam wand and press the steam button (B9)

• To froth the milk, rest the steam wand (A9) on the surface of the liquid. This mixes air with the milk and steam.

• Keep the steam wand in contact with the surface, taking care not to let in too much air and create excessively large bubbles.

• Immerse the steam wand below the surface of the milk, this creates a vortex in the liquid.

• Once the milk is heated to the desired temperature, press the steam button again and wait for the flow of steam to stop completely before removing the milk jug from the machine

Barista tips:

• Fresh milk is best. Always use fresh milk straight from the fridge.
• For best results, always replace the milk jug in the fridge when not in use.
• Whole milk ensures optimum results. The appearance and texture of froth depending on the nature of the dairy milk or vegetable beverages utilized.
• After frothing the milk, eliminate unwanted bubbles by swirling the jug gently.

Cleaning the steam wand

• Following use, always wipe the steam wand (fig. 25) with a cloth to remove residual deposits of milk.
• The recommended procedure for in-depth cleaning is to use Eco MultiClean: this product ensures maximum hygiene by removing milk proteins and fats, and can be used for cleaning the entire machine.
• Release steam for a few seconds to clean the wand (fig. 8). Wait until the steam wand has cooled down.
• To ensure the wand works efficiently over time, use the special cleaning mtool (C10) to free the holes (fig. 26) of any obstruction.

PROGRAMMING BEVERAGE QUANTITIES

• Prepare the appliance to deliver 1 or 2 cups of the beverage you want to make, as far as attaching the filter holder (C1) complete with the (C3) or (C4) filter and ground coffee.
• Turn the dial (B8) to select the beverage being programmed.
• Press and hold the OK button (B6) until the machine delivers the desired quantity. The OK button light flashes orange to confirm you are in programming mode.
• When the desired quantity has been reached, release the OK button. The quantity is programmed

SETTINGS MENU

Reset default settings
The OK light (B6) flashes briefly to confirm the reset.

CLEANING THE APPLIANCE

Important!

• Do not use solvents, abrasive detergents or alcohol to clean the coffee machine.
• Do not use metal objects to remove encrustations or coffee deposits as they could scratch metal or plastic surfaces.
• Should the machine remain idle for more than a week, it is advisable to carry out a rinse cycle before preparing any beverages.

CLEANING THE COFFEE MILL

• Clean the attachment area with the brush (C9)
• Use the brush to clean the coffee guide .

Efficient grinding
The burrs are subject to wear over time. As time goes by, to achieve the perfect quantity, you need to turn the dial (B4) towards the highest numbers. When you reach a setting of between 30 and 40, you need to set the extra grinding range (see section “7. Settings menu” – “Extra grinding range”). When the quantity of ground coffee becomes less than expected, contact a service centre to have the burrs replaced. With the new burrs fitted, adjust the coffee mill by accessing the settings menu and selecting the first range of the “extra grinding adjustment” setting. Next, turn the ground coffee quantity dial (B4) to the Min position and set the quantity as for first-time use (see “La “dose perfetta)

WATER HARDNESS
The descale light (B3) comes on following a predetermined period of operation that depends on a water hardness setting. The machine can also be programmed according to the actual hardness of the local water supply, in which case descaling may be required less frequently (see section “7. Settings menu”).

• Remove the “TOTAL HARDNESS TEST” indicator paper (C5) from its pack.
• Immerse the paper completely in a glass of water for about one second
• Remove the strip from the water and shake lightly.
• Set the machine accordingly, as indicated in the section “7. Settings menu”.

HOW TO USE SOFTBALLS (CERTAIN MODELS ONLY)
Softballs (C7) are an innovative treatment system that prolongs the life of the machine, without altering the properties of the water, while ensuring consistently creamy and aromatic coffee. To optimize the effectiveness of the treatment, leave Softballs in the water overnight before use.

• * Take the sachet of Softballs from the wrapper 

  • Rinse the sachet of Softballs under running water.

• Immerse the sachet in the water tank (A7)

DESCALING

• When the indicator light (B3) comes on, you need to descale the appliance. You can start descaling at any time.
• Remove and empty the drip tray (A19), then reposition it in the machine.
• Empty the water tank (A7). (If present, remove the softballs and place in a glass of water until they can be re-inserted at the end of the descaling process.)
• Pour the descaler into the water tank (C6) up to the level A marked on the inside of the tank (corresponding to the contents of one 100ml pack) .
• Add water (1 litre) up to level B. Now reposition the water tank in the machine.
• Turn the dial (B8) to  The OK light turns orange and the light flashes
• Make sure the filter holder (C1) is not attached. Position a container under the coffee spouts (A10) and hot water spout (A11) and another under the steam wand (A9)
• Press the hold the OK button (B6) for at least 3 seconds. The OK light flashes.
• The descaling programme starts and the descaler liquid comes out of the spouts.
• The descale programme removes limescale deposits from inside the appliance by automatically performing a series of rinses and pausesuntil the tank is empty.
• Descaling ceases and the OK light turns white. This means that a rinse cycle must be carried out:
• Empty the containers used to collect the descaler solution and reposition them under the spouts.
• Remove the water tank, empty out any residual descaler solution, rinse under running water and fill with fresh water up to the MAX level  Put the tank back in its housing.
• Press the OK button. The rinse cycle starts.
• When rinsing is complete, delivery stops. The light flashes red and the OK light goes out.
• Empty the recipient used to collect the rinse water.
• Remove and empty the drip tray (A19), then reposition it in the machine.
• Remove the tank, fill with fresh water and reposition in the machine. (If present, rinse the softballs with running water and put back in the tank).
• Turn the function selection dial (B8) to one of the beverages. The machine is now ready for use.
