the following parts:
• Steam Boiler (produces steam and hot
water)
• Coffee (“saturation”) 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 bench 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:

4 groups 15 liters
2000 or 3000 Watts
3000 or 4000 Watts
3800 or 5000 Watts
Covers are installed 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 a pressure switch or a
5
temperature probe. The steam boiler has
various ittings used for safety devices, hot
water, 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

1400 Watts
1600 or
1900 Watts
4 groups 3.4+3.4 liters 1400+1400 Watts
(2 Boilers Installed)
Covers are installed 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 accepts the portailter used to
hold the ground coffee; Hot water under
pressure lows through the brewing group,
through the portailter basket, through
the portailter spout, and into the cup(s)
after the brew button has been pressed
preparing espresso.
• Exterior cover
It consists of a stainless sheet steel
body for the GB/5 and painted plastic
for FB/80. The structure has been the
object of speciic studies to provide good
aesthetics, to lower ergonometric costs for
the operator and to reduce the chance of
damage to a minimum.
• Water pump
The water pump, is a differential pressure,
“positive-displacement” type installed
on the water supply tubing and is set-up
to operate anytime the coffee groups are
activated, and through an autoill system
whenever the steam boiler needs to be
replenished.
• Sound pressure
The weighted sound pressure level o f the
machine is lower than 70dBA.

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

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 ill the boiler
tanks with water. Complete the following
procedure to properly ill the boiler tanks:
EN
• Coffee boiler
The water lows inside the coffee boiler
directly, as soon as the water system and
water ilter/softener taps (if present) are
opened. Since the inlow 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 cup tray grates 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
ig.4) to allow air to escape until water
lows from below the screw head.
11
Fig.4
Tighten the screw to stop the water from
lowing. 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-ill solenoid valve and
the motor pump. This will ill 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, ig. 1) when the water is
allowed to low 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 conirm 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.
3) Brewing after irst installation
Once the irst installation procedures are
inished, before proceeding with brewing
coffee, hot water and steam, please follow
these steps:
- Engage the portailters 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 portailters
Install the portailter(s) by inserting them
into the group and rotate the handle from
left to right. When the portailters are
inserted properly, you can press any of brew
buttons to start the low of water through
also in case the valve remains open in the
drain position (i.e. the pressure cannot
increase to 8 bar approx.).
Filter Basket
Porta Filter
Note: It is important to leave the portailters
installed in the espresso machine when
not in use. The portailter must remain
heated for the brew process to function
correctly.
5) Water pump
Whenever you are brewing coffee, 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
suficient, remove the valve and clear away
any calcium deposits. This remedy is valid

6) Brewing coffee
It is now possible to remove one of the
portailters to make an espresso beverage.
Place some ground coffee in the ilter
itself: 1 dose (approximately 6-7 g) for
the small ilter, 2 doses (2 approximately
12-15 g) for the larger ilter. Press down
on the ground coffee with the supplied
tamper and install the ilter 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 see picture below).

reason. Please experiment to ind 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
irst two buttons on each group (numbered
left to right).
Please consult the
Software Programming Manual for further
instructions.
EN
8) General notes for coffee preparation
The portailters 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
portailters installed in the machine when
not in use. The portailters may also be
actively heated. This procedure may be
carried out by brewing some hot water
through the portailter then turning off the
water low, before making coffee.
13
It is important to remember that coffee left
over in the ilters 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 ilter.
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 low
out from the ilter holder spouts neither
too slowly (drop by drop) nor too quickly
(quick light brown low). A general rule
is that a double dose should dispense
approximately 25cc or 2 luid oz. of
espresso in approximately 25 seconds.
WARNING
DO NOT REMOVE THE FILTER HOLDER WHILE RELATIVE
GROUP IS BREWING HOT LIQUIDS. 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 lavor 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) 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,
ig. 1) which are connected to the steam
valve, into the liquid to be heated, turn the
steam knob (part 9, ig. 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 overlow in
order to avoid severe burns.
In order to prepare milk for making
cappuccino with the right amount of foam,
go through the following steps:
• Place the container half-full of milk under
the steam wand, open the steam valve and
heat the milk to desired temperature.
• Lower 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. 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
You may dispense hot water by using the
ixed nozzle (item 10 ig 1). To dispense
hot water, press the tea water button on
the right most group.
This button commands the hot water
delivery.
In order to prevent the heated liquid from
being sucked back into the steam boiler
it is recommended 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.
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.
