4. Machine Operation and Coffee Preparation

1) Starting the espresso machine

a) Filling the boilers with water

Once the installation procedures have beencompleted,itisnecessarytofillthe boiler tanks with water. Complete the following procedure to properly fill the boiler tanks:

• Coffee boiler

The water flows inside the coffee boiler directly, as soon as the water system and water filter/softener taps (if present) are opened. Since the inflow of water will compress the air in the boiler it will be necessary to remove or “bleed” the air from the coffee boiler. All air must be removed in order to completely “saturate” the coffee boiler/ group assemblies. To remove the air from the boiler, “bleed the groups”, it will be necessary to remove the group cover from the top of the machine. First removethegrouptrayfromthetopofthe machine exposing the cup tray. Remove the screws securing the group cover and then remove it. Once removed the top of the groups will be exposed.

Loosen the bleed screws one at a time (see fig.4) to allow air to escape until water flows from below the screw head.

11

Fig.4

Tighten the screw to stop the water from flowing. Over tightening can cause damage to the sealing washer and the group cover. Repeat this procedure for all groups. Once all air is removed from thecoffeeboiler,reinstallthegroupcover by following the removal instructions in reverse.

• Steam boiler

Turn the main switch (item 1 in Fig. 1) to position “1” or ON, the automatic steam boiler level gauge will be switched on, activatingtheauto-fillsolenoidvalveand the motor pump. This will fill the steam boiler to a predetermined level and will shut off when full.

Note: It may happen that the air inside the steam boiler builds up pressure (which may be detected through the pressure gauge - item 2, fig. 1) when the

water is allowed to flow in; this “false” pressure must be eliminated by opening the steam valves (item 8, Fig. 1).

b) Turning the espresso machine on

Once you have completed these procedures, check the display. Press enter to confirm that the preceding procedures are complete.

The installation is now complete and the espresso machine should be heating to theoperatingtemperatures.

2) Waiting for the espresso machine to heat to operating temperature

During this time, it may happen that the pointerofthecoffeeboilerpressuregauge reaches as high as 14-15 bar. This may happenanytimethattheheatingelement is in the on condition. In this case it is necessary to adjust the expansion valve (Fig. 3) in such a way that the pressure may never exceed 11-12 bar. In normal operating conditions, the coffee boiler pressure gauge can read anywhere from 0-12bar.

Whenbrewing,thepressureshouldbeset to9bar.

When the steam boiler reaches operating temperature,thelightontheTeadispense buttonwilllight.

When the espresso machine is ready to operatealllightsonthekeypadswilllight.

3)Brewing after first installation

Once the first installation procedures are finished,beforeproceedingwithbrewing coffee, hot water and steam, please follow these steps:

-Engage the portafilters by inserting them into each group, brew water through each group for at least two minutes.

-Being careful to avoid burns, turn on eachsteamwandforatleastoneminute.

-Turn on the hot water valve for the time necessary to allow the following quantities of water to be brewed:

At least 1 liter for a 1/2 group machine At least 2 liters for a 3 group machine At least 3 liters for a 4 group machine

4) Installing the portafilters

Install the portafilter(s) by inserting them intothegroupandrotatethehandlefrom left to right. When the portafilters are inserted properly, you can press any of brew buttons to start the flow of water through the portafilter. You should allow hot water to pass through the empty portafilter(s) for a few secondseach time, inordertopre-heattheportafilter.

Note: It is important to leave the portafilters installed in the espresso machine when not in use. The portafilter must remain heated for the brew process tofunctioncorrectly.

5) Water pump

Whenever you are brewing coffee, and you can adjust the pump pressure by turningtheby-passscrew(belowtheplug located on the side to which the pump power supply is connected) clockwise to increaseandcounter-clockwisetoreduce pressure. Adjust pressure only when at least one group is brewing coffee.

Note: When the heating element in the coffee boiler is energized, the water will expand increasing the start-up pressure. Once the maximum pressure is reached, the expansion (safety) valve should start working by discharging a few drops of water, in order to prevent such pressure from exceeding 11-12 bar.

In case the pressure exceeds 12 bar, you must adjust the expansion valve by unscrewing the cap slightly. If this is not sufficient, remove the valve and clear awayanycalciumdeposits.Thisremedyis valid also in case the valve remains open in the drain position (i.e. the pressure cannot increase to 8 bar approx.).

6) Brewing coffee

It is now possible to remove one of the portafilters to make an espresso beverage. Place some ground coffee in the filter itself: 1 dose (approximately 6-7 g) for the small filter, 2 doses (2 approximately 12-15 g) for the larger filter. Press down on the ground coffee with the supplied tamper and install the filter holder up again to the bottom of the group and then press a button (AV model) to begin the brewing process, or move the paddle lever (MP model).

Note: Some baristas believe it is important to press the brewing button prior to installing the portafilter to allow the water to flush any remaining coffeeEN

12

oils and particles from the group. Some also flush just after brewing coffee for the same reason. Please experiment to find the best possible procedure for you.

7)Controlling the brew process using volumetric programming (AV model only)

This espresso machine allows the volumetric programming of each of the first two buttons on each group (numbered left to right). Please consult the Software Programming Manual for further instructions.

8)General notes for coffee preparation

The portafilters must remain heated since they are at the lowest position of the group itself, and they are partially isolated due to the rubber gasket betweenthem.Thiscanbeaccomplished

by leaving the portafilters installed in the machine when not in use. The portafilters may also be actively heated. This procedure may be carried out by brewing some hot water through the

portafilter then turning off the water flow, before making coffee.

It is important to remember that coffee left over in the filters must be removed only when you need to prepare another cup, and only at that time should you place a new dose of ground coffee in the filter.

The size of the coffee granules is extremely important in preparing a good cup of coffee, other than the type of coffee mix used, quite obviously. The ideal grinding can be determined by makingvariouscoffeesusingtheamount ofgroundcoffeethatyouwouldnormally useforeachcup(werecommendatleast 6-7g). The best grinding is that which allows coffee to flow out from the filter holderspoutsneithertooslowly(dropby drop) nor too quickly (quick light brown flow). Ageneralruleisthatadoubledose should dispense approximately 25cc or 2 fluid oz. of espresso in approximately 25 seconds.

CAUTION

NEVER REMOVE THE FILTER HOLDER WHEN

WATER IS BEING DELIVERED.

THIS OPERATION

CAN BE EXTREMELY DANGEROUS SINCE THE HIGH PRESSURE BUILT-UP INSIDE THE BLIND FILTER WOULD SPRAY OUT HOT AND SLIGHTLY CAUSTIC WATER, WHICH MAY CAUSE SEVERE BURNS.

THE COFFEE BOILER CONTAINS WATER AT ELEVATED TEMPERATURE. WATER TEMPERATURE OVER 125°F / 52°C CAN CAUSE SEVERE BURNS INSTANTLY OR DEATH FROM SCALDING.

IMPORTANT

To improve the flavor of the espresso, the temperature of the water in the coffee boiler and therefore of the groups may eventually be raised or lowered via the digital display (please consult the Software Programming Manual for detailed instructions).

5. Dispensing Steam and Hot Water

1) Steaming milk or other liquids

In order to allow for any condensed waterinthewandtobereleasedALWAYS allow some steam to be discharged by turning on the valve before inserting the steam wand into the pitcher of liquid to

be heated.

Dip one of the 2 steam wands (part 7, fig. 1) which are connected to the steam valve, into the liquid to be heated, turn the steam knob (part 8, fig. 1) gradually until steam comes out at the end of the wand.

The steam will transfer heat to the liquid raising its temperature up to boiling point.

Be careful not to allow liquid to overflow in order to avoid severe burns.

In order to prevent the heated liquid from being sucked back into the steam boiler it is recommended before using thewandthatyoupurgethesteamvalve andsteamwandbyopeningthevalvefor a few seconds to allow steam to escape to the atmosphere from the end of the steam wand. Failure to do so can cause the heated liquid to transfer from the heated liquid container to the steam boiler (via vacuum created from cooling

brew water for 3 sec and repeat ten times for each group.

- Rinse the group using a normal filter, by running hot water through it several times

2) Cleaning filters

-Put 2 or 3 teaspoons of detergent powder for coffee machines in about 1/2 a litre of water inside a heat-resistant container and boil.

-Dip filters in the boiled solution and leave them fully submerged for about 30 minutes.

-Rinse thoroughly with clean water and run hot water through one group several times with the filters in place.

-Make one cup of coffee and discard in order to remove any unpleasant flavor.

3)Cleaning filter holders (portafilters)

Using the proper cleaning tool (brush) wash the filter holders under hot water, aneutraldetergentmayalsobeused.For extraordinarycleaningseethePortafilter Manual.

4)Cleaning the drain collector

Remove the drain tray grill at least twice a week and clean, pull out the water drain collector and clean it thoroughly. Inspect and clean also the drain box and remove any leftover grounds.

5) Cleaning the body

Wipe the stainless steel surfaces with a soft, non abrasive cloth in the direction of the glazing marks, if any. Do not use any alcohol or solvents whatsoever on painted or imprinted parts in order not to damage them.

6)Cleaning the hot water and steam nozzles

Steam nozzles must be cleaned immediately after use with a damp cloth and by producing a short burst of steam so as to prevent the formation of deposits inside the nozzles themselves, whichmayaltertheflavorofotherdrinks tobeheated. Hotwaternozzlesmustbe cleaned periodically with a damp cloth.

7)Cleaning the diffuser screen

-Duetofilterholderdischargeoperations (subsequenttocoffeebrewing),acertain amount of coffee grounds may slowly build-up on and obstruct, even partially, the diffuser screen. To clean it, you must firstremoveitbyunscrewingthediffuser screw.
