1) General description

The machine is built in 2, 3, and 4 coffee group versions and is essentially composed of the following parts:

• Steam Boiler (produces steam and hot water);

• Coffee (“saturated”) boiler;

• Brewing groups;

• Exterior Cover;

• Water pump.

2) Description of the various parts

• Steam Boiler

The Steam Boiler consists of a cylindrical tank, of varying length according to the number of coffee groups, which is made of AISI 300 series stainless steel. Each unit is subjected to a hydraulic test, at a pressure of 6 bar, and has an operating pressure of 1.3-

1.5 bar. The following is a list of effective

volumes and power ratings according to the number of groups installed:

2 groups 7 liters 3 groups 11 liters 4 groups 15 liters

Covers are welded at either end of the cylindrical tank and on one of them there is a housing for the water heating element, which allows the steam boiler to reach operating pressure within approximately 25 minutes.

Operating pressure is maintained

by an electronic temperature probe with a PID controller various ttings used for safety devices, for supplying hot water and steam, and for the

heating element.

• Coffee boiler

The Coffee Boiler consists of a cylindrical tank, of varying length according to the number of coffee groups, which is made of AISI 300 series stainless steel. Each unit is subjected to a hydraulic test, at a pressure of 18 bar, and has an operating pressure of 9 bar. The following, table is a list of effective volumes and power ratings according to the number of groups installed:

2 groups 3.4 liters 3 groups 5 liters 4 groups 6.8 liters

Covers are welded at either end of the cylindrical tank and on one of them there is a housing for the water heating elements. The temperature of the coffee boiler is maintained by an electronic temperature controller (PID capable) with an accuracy of 0.2°C. The brewing groups are installed on the boiler.

• Brewing groups

They consist of a precision casting made of stainless steel. The brewing group

. The steam boiler has

accepts the portalter used to hold the ground coffee; the espresso ows through the brewing group, through the portalter basket, through the portalter spout, and into the cup(s) after the brewing button has been pressed.

• Exterior cover

The exterior consists of painted and stainless sheet steel panels. To provide good aesthetics, to optimize ergonometrics for the operator and to reduce the chance of damage to a minimum.

• Water pump

The rotary vane pump, is installed on the water supply tubing and is set up to operate anytime the coffee groups are activated, and through an autoll system whenever the water boiler needs to be replenished.

• Sound pressure

The weighted sound pressure level of the machine is lower than 70dBA.

• Water inspection window

The position of this device enables to verify only water presence inside the steam boiler. The water level in the window provides a reference about the water level in the steam boiler, but doesn’t represent it in a directly proportional way, 1/3 of the windows is equal to approximately 1/2 of the boiler.

3) Water test kit

In order to enable you to check if your water supply is within the suggested ranges, La Marzocco machines will be equipped with two units of a quick water test kit (see image below) including 6 test-strips and instruction

cards.

The parameters that you can measure are Total Hardness, Total Iron, Free Chlorine, Total Chlorine, pH & Total Alkalinity, Chlorides. Ideally, you should perform a test on the water BEFORE the water treatment system and again AFTER the water system in order to verify if this is actually matching our suggested ranges. Once the test has been performed, learn which treatment system is most appropriate for your particular water supply by lling out

the online water calculator on our website: LA MARZOCCO WATER CALCULATOR (http:// www.lamarzocco.com/water_calculator/).

4) Water supply connection

In order to connect the machine up to the water mains proceed according to the indications given in the chapter about Installation and in compliance with any local/ national safety standards of the location in which the machine is being installed. To guarantee a correct and safe functioning of the machine and to maintain an adequate performance level and a high quality of the beverages being brewed it is important that the incoming water be of a hardness greater than 7°f (70ppm, 4°d) and less than 10°f (100ppm, 6°d), pH should be between 6.5 and 8.5 and the quantity of chlorides be less than 50mg/l . Respecting these values allows the machine to operate at maximum efciency. If these parameters are not present, a specic ltration device should be installed, while always adhering to the local national standards in place regarding potable water. Then connect the inlet of the water lter/ softener (if present) to the drinking water supply using one of the supplied stainless steel braided hoses. Before connecting the lter to the water pump, ush the water supply line and the ltration system in order to eliminate any residual particles which could otherwise get stuck in taps or valves

thus preventing them from working properly.

4. Machine Operation and Coffee Preparation

1) Starting the espresso machine

a) Filling the boilers with water

Once the installation procedures have been completed, it is necessary to ll the boiler tanks with water. Complete the following procedure to properly ll the boiler tanks:

• Coffee boiler

The water ows inside the coffee boiler directly, as soon as the water system and water lter/softener taps (if present) are opened. Since the inow 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 remove the group tray from the top of the 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 g.4) to allow air to escape until water ows from below the screw head.

Fig. 5 - AV Version

Fig. 6 - MP Version

Tighten the screw to stop the water from owing. 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 the coffee boiler, reinstall the group cover 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, activating the auto-ll solenoid valve and the motor pump. This will ll 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, g. 1) when the water is allowed to ow 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 conrm that the preceding procedures are complete. The installation is now complete and the espresso machine should be heating to the operating temperatures.

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

During this time, it may happen that the pointer of the coffee boiler pressure gauge reaches as high as 14-15 bar. This may

happen anytime that the heating element

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 0-12 bar. When brewing, the pressure should be set to 9 bar. When the steam boiler reaches operating temperature, the light on the Tea dispense button will light. When the espresso machine is ready to operate all lights on the keypads will light.

3) Brewing after rst installation

Once the rst installation procedures are nished, before proceeding with brewing coffee, hot water and steam, please follow these steps:

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

- Being careful to avoid burns, turn on each steam wand for at least one minute.

- 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 portalters

Install the portalter(s) by inserting them into the group and rotate the handle from left to right. When the portalters are inserted properly, you can press any of brew buttons to start the ow of water through the portalter. You should allow hot water to pass through the empty portalter(s) for a few seconds each time, in order to preheat the portalter.

Note: It is important to leave the portalters installed in the espresso machine when not in use. The portalter must remain heated for the brew process to function correctly.

5) Water pump

Whenever you are brewing coffee, and you can adjust the pump pressure by turning the by-pass screw (below the plug located

on the side to which the pump power supply is connected) clockwise to increase and counter-clockwise to reduce 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 sufcient, remove the valve and clear away any calcium deposits. This remedy is 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 portalters to make an espresso beverage.

Place some ground coffee in the lter itself: 1 dose (approximately 6-7 g) for the small lter, 2 doses (2 approximately 12-15 g) for the larger lter. Press down on the ground coffee with the supplied tamper and install the lter 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 portalter to allow the water to ush any remaining coffee oils and particles from the group. Some also ush just after brewing coffee for the same reason. Please experiment to nd 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 rst 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 portalters must remain heated since they are at the lowest position of the group itself, and they are partially isolated

due to the rubber gasket between them. This can be accomplished by leaving the portalters installed in the machine when not in use. The portalters may also be actively heated. This procedure may be carried out by brewing some hot water through the portalter then turning off the water ow, before making coffee.

It is important to remember that coffee left over in the lters 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 lter.

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 making various coffees using the amount of ground coffee that you would normally use for each cup (we recommend at least 6-7g). The best grinding is that which allows coffee to ow out from the lter holder spouts neither too slowly (drop by drop) nor too quickly (quick light brown ow). A general rule is that a double dose should dispense approximately 25cc or 2 uid oz. of espresso in approximately 25 seconds.

NEVER REMOVE THE FILTER HOLDER WHEN WATER IS

CAUTION

BEING DELIVERED. THIS OPERATION CAN BE EXTREMELY

DANGEROUS SINCE THEHIGH 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 avor 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 water in the wand to be released ALWAYS 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, g. 1) which are connected to the steam valve, into the liquid to be heated, turn the steam knob (part 8, g. 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 overow 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 the wand that you purge the steam valve and steam wand by opening the valve for 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 parts). This condition is undesireable and can cause contamination in the steam boiler. After use remember to purge the wand by opening the steam valve for a few seconds,

and then clean the outside of the wand itself with an appropriate cloth. In order to prepare milk for making cappuccino with the right amount of foam, go through the following steps:

• After purging the steam wand place the container half-full of milk underneath, carefully open the steam valve and raise the container so as to bring the wand end to a point just below the surface of the milk; at this point, move the container up and down just enough to dip the nozzle end in and out of the milk until you get the right amount of foam, bring the temperature of the milk almost up to 149/158°F or 65/70°C. You can then pour this milk into a cup containing warm espresso and you will end up with a fresh cup of cappuccino.

2) Preparing tea and other hot drinks

TEA

You may dispense hot water by using the xed nozzle (item 9 g 1). To dispense hot water, press the tea water button on the right most group. This button commands the hot water delivery.

The volume of water delivered may be adjusted via the display (see the Software Programming Manual for further instructions). The temperature of the water dispensed may be adjusted by adjusting the mixing valve under the right side cover of the espresso machine. (only on the models of espresso machine equipped with this accessory)

WATER TEMPERATURE OVER 125°F / 52°C CAN CAUSE

SEVERE BURNS INSTANTLY OR DEATH FROM SCALDING.

- For AV models: activate the automating rinsing (backushing) routine (see the Software Programming Manual for more detailed instructions). For MP models: brew water for 3 sec and repeat ten times for each group.

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

2) Cleaning lters

- 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 lters 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 lters in place.

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

3) Cleaning lter holders (portalters)

Using the proper cleaning tool (brush) wash the lter holders under hot water, a neutral detergent may also be used.For extraordinary cleaning see the Portalter 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, which may alter the avor of other drinks to be heated. Hot water nozzles must be cleaned periodically with a damp cloth.

7) Cleaning the diffuser screen

- Due to lter holder discharge operations (subsequent to coffee brewing), a certain amount of coffee grounds may slowly build-up on and obstruct, even partially, the diffuser screen. To clean it, you must rst remove it by unscrewing the diffuser screw.

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