1) General Description

The machine is built in 2 and 3 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 8,2 liters 3000 Watts

3 groups 11,8 liters 4000 Watts

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 temperature probe and PID controller.

The steam boiler has various ttings used

for safety devices, for supplying hot water

and steam, and for the heating element.

Composed of AISI 300 series stainless

steel tube. Heating is accomplished

through an immersion-type plated heating

element.

• Operating pressure of 1.3-1.5 bar,

controlled automatically through a

pressure switch or a temperature

probe, adjusted to open the heating

element supply circuit at 1.5 bar and

close it at 1.3 bar.

• The pressure is displayed by means of

a pressure gauge with a scale of 0 to 2

bar.

• Safety device, based on an expansion

type mechanical valve, with counter-

acting spring adjusted to 1.8 bar.

• Testing: hydraulic test at 4.5 bar

performed on ready-to-use small

boilers, at our factory.

• Coffee Boiler

The Coffee Boiler consists of a cylindrical

tank made of AISI 300 series stainless

steel. One each group (hot water generator

for brewing coffee).

Each unit is subject to a hydraulic test,

at a pressure of 18 bar, and has an

operating pressure of 9 bar. The following

is a list of effective volume and power

ratings according to the number of groups

installed:

2 groups 2 x 1,3 liters 2 x 800 Watts

3 groups 3 x 1,3 liters 3 x 800 Watts

Covers are installed at either end of the

cylindrical tank and on one of them there

is 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.

Composed of an AISI 300 series stainless

steel tube. Heating is accomplished

through an immersion-type plated heating

element.

• Operating temperature 95°C (adjustable),

controlled automatically by an electronic

temperature controller with an accuracy

of 0.2 °C. Operating pressure of 9 bar,

developed mechanically by a special

positive-displacement pump which

is activated automatically every time

coffee is brewed.

• Pressure is displayed through a pressure

gauge with a scale from 0 to 15 bar.

• Safety device, based on an expansion

type mechanical valve, with

ounteracting spring adjusted to 13.5

bar.

• Testing: Hydraulic test at 18 bar

performed on ready-to-use small boilers,

at our factory.

• Brewing groups

They consist of a precision casting made

of stainless steel. The brewing group

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

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) 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.

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).

Note: The water pump is a differential

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

• 220VAC 3 Phase 4-core cable with 4

mm2 cross section for 2 , 3 and 4 group

versions, secured to espresso machine via

a strain relief connector

• 380 VAC 3 Phase 5-core cable with

2.5mm2 cross section for 2, 3 and 4 group

versions, secured to espresso machine via

a strain relief connector.

b) Water pump motor power cord

This is the power supply for the water

pump motor. The internal electronics will

switch the pump motor on when needed.

• 3-core cable with 1.5 mm2 cross section

or 3-core AWG 16 (for UL version) secured

to espresso machine via a strain relief

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

4. Machine Operation and Coffee Preparation

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.

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).

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.

WARNING

This machine is designed only for

preparing coffee and hot drinks.

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 to

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

13.5bar.

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.

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.

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).

- Put a tablespoon of detergent powder

for coffee machines into the blind lter,

supplied with the machine, and tighten it

onto the group you want to clean by using

a normal lter holder.

- Turn the Paddle Valve on and off

approximately 10 times (10 seconds

intervals) on 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
