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) Flowmeter safety removal

Before switch on, remove the clamp from the owmeter located inside the machine, as indicated by the adhesive label applied on the main switch. Also remove the label from the main switch.

Page 15

5) 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. Connect the water supply connection of the espresso machine to the water pump outlet using one of the supplied stainless steel braided hoses. Then connect the water pump inlet to the water lter/softener outlet (if present).

The water pump is a differential

Note:

pressure volumetric pump and has been designed to be used exclusively with cold water. Make sure that water is always present while the pump is operating, otherwise air can be introduced into the brew boiler causing an undesireable condition and the pump can be damaged.

6) Electrical connections a) Power supply cord

• This is the main power supply cable that provides power to the entire espresso machine. There are different types of cable based upon the electrical requirements of the espresso machine purchased:

• 200/220VAC 1 Phase 3-core cable with 4/6/10mm2 cross section or AWG 12/10/8 for 2,3 4 group versions, secured to espresso machine via a strain relief connector

CAUTION

Never remove the lter holder

when water is being delivered.

This operation can be extremely

dangerous since the high

pressure built-up inside the blind

lter 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.

WARNING

The machine must not be dipped

in, nor splashed with, water in order to clean it. For cleaning

operations, please follow the

instructions listed below very

carefully.

4. Machine Operation and Coffee Preparation

WARNING

This machine is designed only for

preparing coffee and hot drinks.

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).

1) Starting the espresso machine

a) Filling the boilers with water

Once the installaon 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 purier 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 boilers. All air must be removed in order to completely “saturate” the coffee boiler/

group assemblies. To remove the air from the boiler, or “bleed the groups”, it will be necessary to remove the plastic keypad from the top of the group.

Loosen the bleed screws one at a time to allow air to escape until water ows from below the screw head. 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 on all groups.

• Steam boiler

Turn the main switch to position “1” or ON, the automatic steam boiler level gauge

Page 18

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: Air inside the steam boiler may build up pressure (which may be detected through the pressure gauge). Once the pump stops, check the display, the message “Coffee Boiler Filled?”

should be displayed. Press conrm that the preceding procedures are complete. The installation is now complete and the espresso machine should be heating to 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 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 (see the picture below about the three coffee boiler expasion valves) in such a way that the pressure never exceeds 13 bar.

Expansion

Valve

In normal operating conditions, the coffee boiler pressure transducer, while brewing, can read anywhere from 0-12 bar when brewing. When the steam boiler reaches operating temperature, the light on the Tea dispense button will switch on.

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

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) Brewing coffee

Now you can brew an espresso. Disengage one of the portalters, ll the lter with ground coffee, tamp the ground coffee with the tamper supplied (exerting a force of 20 kg) and re-engage the portalter to the group. Press a button on the keypad to begin the brewing process.

Some baristas believe it is important

Note:

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.

6) 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.).

7) 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.

8) Cup Warmer

Press Cup Warmer Button for enabled or disabled the cup warmer. This function work in two modes continuous or timed (see the Software Programming Manual for further 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 8, page

7) which are connected to the steam valve, into the liquid to be heated, turn the steam knob 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.

TE'

You may dispense hot water by using the xed nozzle (part 6, page 7). To dispense hot water, press the tea water button.

This button commands hot water delivery. The temperature of the water may be adjusted by adjusting the mixing valve.
