Introduction
Congratulations on the purchase of the worlds first
prosumer, computer controlled pressure profiling
Vesuvius using and E61 group. This advanced
espresso machine uses true pressure profiling via
the FG304 gear pump and speed controllable
brushless motor. Currently there is no other
prosumer machine available with these functions, so
some of the techniques for using the Vesuvius are
slightly different to other espresso machines
The pump and pressure settings can be set up in
many ways, so many, that the owners manual is just
a starting point for your journey.
Paolo Cortese (Designer, Director)
Antonio Nurri (Director & Head of marketing)

Product Safety Notice
This manual is an integral and essential part of the
product and is to be delivered to the user. Carefully
read all warnings as they provide important
information required to install, use and maintain the
Vesuvius
Inspection and unpacking
After having removed the packaging, make certain
that the Vesuvius is not damaged in any way. If you
have any doubts, do not use the Vesuvius and
contact a professionally qualified person or your
dealer. Always keep all packaging including any
plastic bags, internal packing screws, and rubber
transit feet etc.). All packing materials should be
kept out of reach of children and disposed of
responsibly in accordance with your countries
recycling and disposal arrangements.
General Installation precautions
Before switching on the Vesuvius make certain
that the rating indicated on the label matches the
available power supply. The serial number and
rating label is located behind the drip tray.
Installation should be in line with the standards and
laws within the of the country where it is being
installed, following any manufacturer's specific
instructions and checks.
Properly skilled personnel should install when
connected to the rising main. The manufacturer
cannot be held responsible for any damages
incurred if the system is not electrically grounded, or
by water leaks when connected to the rising main.
For electrical safety, this machine requires a ground
or earth. If in any doubt contact a technically certified
electrician who must check that the electrical outlet
used has adequate capacity for the current draw of
the machine and that it is properly grounded.
The use of extension leads, adaptors or any other
equipment between the Vesuvius and the mains
supply socket is not recommended. If for any reason
this type of equipment must be used, you should
consult a qualified electrician. Different countries
have different regulations for plumbed in
machines. Before plumbing in the Vesuvius, you
should consult with a qualified plumber and/or
ensure all in county regulations are followed.
Always ensure the portafilter is locked in
correctly
Failure to do this can result in the portafilter coming
undone, with the risk of scalding or breaking any
cups below. Please lock to the 6:00 position or
further for safe operation

Unpacking the Vesuvius
The Vesuvius comes in a special protective wooden
case, this item has been designed to not only protect
the Vesuvius, but when disassembled folds flat to
allow the Vesuvius to be repackaged for
transportation at any time. To remove the Vesuvius
from the case the following unpacking procedure
should be used.
1. All 4 screws securing the lid should be
removed. There are 1 on each side shown
by the arrows, 4 in total. Note: they are
NOT on the top.
2. The sides of the crate are secured by 4
metal clips, each held in place by a screw
that should be removed.
3. Remove the clips
The sides of the case can now be lifted away from
the base and the sides folded flat for storage.
The Vesuvius is secured to the base using rubber
transit feet with bots on the bottom that protrude
through the case and are secured with 4 wing nuts,
these must be undone. .
Once the wing nuts have been undone, the machine
will lift away from the base and will have 4 soft
rubber transit feet attached. These feet should be
removed.

Attaching the feet
Remove the 4 transit feet and store in the accessory
case. The machine comes supplied with 4 feet in the
accessory case. 2 small and 2 large. The large are
placed on the rear mounting holes and the 2 small
ones are placed in the very front mounting holes.
The extra holes near the middle are only used for 2
of the 4 transit feet.
The Accessory Tray
The machine comes with a wooden accessory tray,
that has a lid. All supplied accessories will be in this
tray. It also functions to store screws clips and
transit feet, should the machine ever need to be
repacked into it's protective shipping case.
Mains Water Connection
The Vesuvius is supplied ready for a mains water
connection or internal tanked operation. As the
Vesuvius only uses the mains water connection
to fill it's internal tank and the pump always
draws from the internal tank. A pressure reducer
is not required when plumbing in. Use the flexible
hose provided with the machine, connect it to a
connection hose 3/8” male with a shut off valve. The
use of a water softer or filtration system, is advised.
The drip tray can be plumbed to the waste or left
unplumbed.
To plumb to the waste use the flexible hose provided
and remove the rubber stopper in the pipe at the
rear of the tray. The mains water connection is
underneath the machine towards the back.
The internal tank
The internal tank is accessed by opening the left
side panel using the opening latch.
Remove the tank and wash in warm soapy water
before first use. Ensure all tubes are replaced in the
tank. The longer of the 2 tubes must reach all the
way to the bottom of the tank (this is the pump inlet),
make sure the small particulate filter is in place. The
shorter tube is the vent tube from the safety release
valve and need not reach the base of the tank.
Routing the safety pressure release vent valve to the
water tank, protects both you and the machines
electronics if a fault causes any high pressure
venting of steam from the safety valve.
Electronic selection -Tanked or mains
plumbed
There is a switch under the machine at the rear,
after connecting to the water main, this needs to be
switched on...the switch will light when in the on
position.

Operation with Internal Tank
If operating with the internal tank, ensure the mains
water/tank switch underneath is off (not lit). Access
and clean the internal tank as described in the mains
water connection section. The only difference is the
tank must be manually filled with water. Decalcified
water, or water suitably treated for espresso
machines should be used.
Even if the switch is accidentally placed in the mains
plumbed position (illuminated), when running
tanked. The Vesuvius will still work perfectly
normally and not leak water, as a blanking cap is
fitted to prevent water leaking from the mains inlet
pipe. This of course needs to be removed if running
plumbed.
Preparing the Vesuvius for operation
The machine has been correctly installed as per the
previous guidance and is ready to be filled for the
very first time. You can think of this process as
bringing your machine to life. Be watchful during this
time for anything abnormal and to ensure everything
is working correctly. The portafilter should not be
locked into the group yet.
Filling the Vesuvius for the first time
There are 2 boilers in the Vesuvius, the Service
Boiler (Steam & Hot water) and the Brew boiler, for
coffee brew water only. The Service boiler has a
water level probe and will not switch on it's heating
element until the water level reaches the probe. The
brew boiler does not have this probe and does not
know whether the water level is low or not. This
makes some simple precautions important during
the first time fill.
Usually the brew boiler will be full of water from
factory testing, but if for any reason it has been
emptied prior to shipping the following procedure is
advised,
1. Open the side panel and observe the water
level in the tank.
2. Switch on the machine at the mains and
once the firmware has loaded, turn the
machine on from the front panel. Within a
few moments, the pump may start to run
3. Lift the brew lever, always do this!
4. the water level in the tank should fall and
within a short time water should flow from
the group within approx 90s. Lower the lever
when water exits the group.
5. If the pump continues to run, you should
open the steam valve to aid the filling of
the service boiler (only open this once
the brew boiler is full, see 4 above). The
level of water in the tank should continue to
drop when the pump is running and the
service boiler will stop filling automatically.
If water does not appear from the group within 90s
and the tank level is not going down when the pump
runs, check for a blockage, kinked pipe, or other
obvious problem. Wait approximately 1 minute and
try again.
If the service boiler continues to fill with the lever
down, again check the level of water in the tank is
reducing. If not, switch the machine off, check for a
kinked hose or other blockage. Then switch on and
try again.
If the service boiler is filling, the water level is
dropping in the tank, but the pump does not stop
filling due to a fault. You will notice water exiting
from the steam wand (if open), this is a warning to
switch the machine off.. Please contact your dealer
for advice.
Flushing the Vesuvius before using
Although the machine is tested at the factory, we
always advise that you flush before first use. This
removes any stale water and manufacturing
residues from the machine. The following procedure
should be used.
1. Lift the lever and draw 1 litre through the group in
200ml amounts pausing for 15 seconds each time.
2. Switch on the steam boiler, under the eco option
in the main menu (see page 10). Once the steam
boiler has come up to temperature. Switch the
steam boiler off, then switch the machine off and
with a jug under the hot water tap, open the hot
water tap and drain as much water off as possible.
The pump should not run during this process. Switch
the Vesuvius on, allow the service boiler to refill and
repeat this process.
These procedures will remove any stale water and
residues. Any "new machine" taste, will correct itself
in a week or so.

Understanding the display & programming
functions
The Vesuvius dot matrix display is capacitive
sensing and only has to be touched to elicit a
response, no pressure is necessary. The display
may appear not to respond, because some functions
have a programmed delay. In these cases the area
should simply be touched for the appropriate time
e.g. entering the advanced menu has a 10s delay, to
reprogram a profile has a 5s delay.
The display above shows the Vesuvius on standby.
Touching the area marked with a red circle,
switches the machine on and the "home screen"
is shown (below).
The display is split into 3 Horizontal zones. The top
zone shows brew pressure (when brew lever
activated), Steam boiler temperature and pressure.
The next Zone shows what pressure profile is being
used and this is a sideways scrolling display.
The third zone has a tank water level indicator,
which actually only shows full and empty. The
time and day of the week and on the right the brew

Turning the Steam (Service boiler on or off)
The service boiler provides both steam and hot
water. The steam and hot water wands operate only
when it is switched on. To switch the service boiler
on, you enter the ECO menu by the following
sequence
Please note that the steam on/off function is
completely independent of ECO mode. So Eco
Steam (above) might be highlighted, but if the steam
function is not switched on, nothing happens and the
steam boiler will not heat. The Vesuvius will not
enter ECO mode, as the "Eco Steam function"
only operates when the steam boiler is on.
Eco Mode + Eco Steam can be left enabled to work
automatically whenever you switch the steam boiler
on (fast access main menu screen). You don't
longer have to enter advanced menu to
enable/disable Eco mode, unless you want to
change the number of minutes before the machine
enters Eco mode ("Time Economy" function page
12 and 20).

Eco Mode Explained
Eco mode, reduces power consumption and
temperatures inside the machine for longer
component life. It does this by selectively reducing
the temperature of the brew and/or steam boilers,
based on the Eco time set ("Time Economy"
function in the advanced menu).
The Internal Eco timer starts counting down to 0
when there are no operations of the touch screen, or
anything causing the pump to run. Once it reaches
0, Eco mode is triggered The Vesuvius immediately
come out of ECO mode, if the brew lever is lifted, or
the display screen is touched, if not yet in Eco mode,
then the Eco countdown timer is reset.
ECO mode only operates if the "Time Economy"
option on page 20 is set to a number of minutes
greater than 0. This option is accessed via the
advanced menu.
Eco mode reduces the temperature of the brew
and/or steam boiler by the value set in the
advanced menu option "Economy DT". If a value
of 80 is set, boiler temperatures will be reduced by a
value of 80C from their set point. Values larger than
80 cannot be set.
If full ECO mode and not just the steam boiler (eco
Steam) is selected, with a typical "Economy DT" of
67 the brew boiler might reduce from 94C, to a brew
temperature of 27C. this would mean the boiler is
effectively switched off. Economy mode is of very
little use on a brew boiler (home environment),
as the group would cool down and require
significant time to warm up again.
In full eco mode (both boilers), the display switches
to green when it enters ECO mode
ECO setting is most useful when restricted to
operate on the Steam boiler only. Touch to highlight
"Eco Steam" as below.
If the steam (service) boiler is set to 127 and in the
advanced menu, "Economy DT" is set to 67, with
an Economy time ("Time Economy" value) of 4. After
4 minutes of inactivity, the steam boiler temperature
will reduce to 60C.
By setting the steam boiler to run this way, you can
walk away after steaming, knowing that the
temperature will automatically reduce after 4
minutes. This keeps the Vesuvius cooler and gives a
very rapid warm up to full steaming temperature.
60C provides optimum energy efficiency and a warm
up time reduced by 50%. This would allow the
boiler to be ready for steaming in under 3
minutes instead of nearly 6 minutes.
The Steam boiler will come out of ECO mode, when
the brew lever is lifted, the pump runs, or the display
is touched.
There is a further economy setting in the
advanced menu called. "Time to off". This setting
will switch the machine to standby in whatever
number of minutes has been set (max value 999),
after the machine enters economy mode. This can
be useful in a number of circumstances.
If you don't use the daily on/off timers and want the
machine to switch off if it's not being used
Or
You wish the machine to be on before you get up
and go to work, but your work pattern varies. You
can for example, set the machine to come on at 7am
with no off time and on again at 7pm and off at
11pm. You then might set a "Time to off" of 2 hours
If you are in all day and using the machine it will stay
on. If you have to suddenly leave for a meeting, the
machine will switch off after 2 hours and then switch
on again in the evening at 7pm.

Eco Mode Explained (cont.)
Note: Vesuvius will not enter ECO mode, when
the "Eco Steam function" is selected unless the
steam boiler is on, see page 10.
Tip: When in Eco steam mode, a touch on the
Eco (leaf) symbol will immediately put you in
ECO mode and take you back to the home
screen.
The tip above is for the times when you want to brew
a coffee and not necessarily steam milk. Once you
have finished, you may decide to put the Vesuvius
straight back into Eco mode. Again if it helps think of
this fairly quick procedure as:
• 2 touches on the lower right corner of the
display, followed by 2 touches on the top left
corner of the display.
It's a little difficult to understand why it works until
you try it and see that the options are positioned
directly "underneath" each other on the various
screens. When the Home screen is shown, you will
see the word ECO on the display instead of a
temperature.
This also works for full Eco mode (both boilers), but
in this case the display will turn Green.
If the steam boiler is
switched off in the ECO
menu, the display will
show "Off" instead of
steam temperature.
If Eco mode is active
and only the steam
boiler selected. The
home screen will show

achieve results as simple or complex as you care to
program. After you touch and hold a profile icon (P1)
for 5 seconds, you will enter this screen.
This screen tells us that for the 1st phase (of the 7
phases available), the Vesuvius will deliver a
pressure of 2.0 bar for 10s. A global Pump
acceleration parameter (page 20) affects how
quickly the pump responds and will affect the speed
at which any programmed pressure is reached.
• Touching the - or + icon will increase or
decrease the seconds, touching the "tick"
icon will, store the value in memory and
move you to the pressure value.
• The - or + icon will increase or decrease
pressure settings. touching the "tick" icon
saves the settings and displays the next
phase. The procedure is repeated to
program the next phase.
• If no changes are desired, simply touch the
"tick" icon twice to move to the next phase.

Programming/examining pressure profiles
(cont.)
Not all phases have to be used, enter a 0 time and
that phase will not be used. The screens that follow
show the rest of this example profile. Phase 7 is
unused shown by a value of 0 seconds. It is not
necessary to put 0.0 bar as well.
One useful tip, if just a small change is desired,
after touching the "Tick" Icon to save the value,
raising and lowering the brew lever returns you to
the Main menu screen.
Profile advice
The Vesuvius has advanced pressure profiling
capabilities but everyone's taste is different, so
some suggestions to get you started below
assuming a pump acceleration value of 400
(factory setting). Always remember, although you
have 7 phases for each profile, you don't have to
use them all.
Phase 1 Preinfusion times for the first low
pressure phase
You can choose to move straight to maximum
pressure, but the Vesuvius benefits from a
preinfusion phase. Note: the preinfusion chamber
within the E61 group has been disabled, as it's
operation interferes with pressure profiling.
Preinfusion, times shorter than 3 seconds will be
ineffective as this will mainly be lost in filling the
inactive preinfusion chamber in the E61 group and
the space above the coffee puck. The filling of the
redundant E61 preinfusion chamber also makes a
pre-flush unnecessary prior to pulling a shot.
Preinfusion times of 6 - 14 seconds have given good
results. With better grinders, even longer times may
be of benefit. Preinfusion pressures can be anything
you want, but not lower than 2 bar, testing has
mainly been with 2 bar preinfusion pressures. Early
testing did not show any benefits with pressure
lower than 2 bar due to low flow rates from the
pump.
One of the reasons the Vesuvius always supplies
the pump from it's internal tank, is to allow
preinfusion pressures lower than mains line
pressure (usually much higher than 2 bar).

Profile Advice (cont)
Phase 2 and beyond - The maximum or
rising pressure phases
You can reach maximum brew pressure any way
you want. A rise in stages from 2 bar to 5 bar and
from 5 bar to 10 bar, or a single rise to 10 bar. It is
up to you to experiment.
You may want higher pump acceleration and a
faster response, moderating the pressure rise by
having two rising stages. Or you may keep the
acceleration at the factory settings and use 2 stages
for a very soft and gentle rise to full pressure. We
have had good results with a single rise to maximum
pressure, but a 2 phase rise may not give benefits
for some coffees/temperatures.
Pressures over 11.5 bar are not recommended, as
the results do not improve beyond this point. The
E61 group has a maximum limit of pressure based
on the Vent release valve spring tension. For most
E61 groups this is around 12.5-13 bar.
Note: the Vesuvius high pressure PTFE tubing and
fittings are rated for 25 bar pressure, well beyond
the capabilities of the pump.
Later phases after maximum pressure
Normally during the extraction process, the pour
starts to blonde and often it loses integrity. We feel
high pressure continually applied causes this and
progressively lowering the pressure as the pour
progresses will result in a better sweeter, more
rounded shot with improved body. This is probably
the reason for the good shots that many spring
lever machines produce, but we have a level of
repeatable control, well beyond that of any lever
machine.
How much you lower the pressure and how fast is
influenced by your taste, the coffee used and the
grinder you have. You need to experiment and share
information with other owners .
How the Vesuvius Controls pressure
The Vesuvius uses pressure transducer, commercial
valve system and PID algorithm to control pump
pressure. Although not perfect, it is better than a
simple on off control, which would be unable to
manage rapidly changing pressures.
You may notice brew pressures can overshoot the
set point sometimes, this mainly happens with
increasing pressures. High pump accelerations
increase this tendency as do different coffees and
grinds. As dynamic pressures approach the
static pressure potential in the system, pressure
changes happen very rapidly. The PID system
reacts very fast, but has a finite reaction time. If PID
settings are made very aggressive to damp this
response it can cause hunting lower down the
pressure ranges as the pressure falls.
These pressure overshoots are brief and have a
minimal effect on the shot, as it's mainly static
pressure showing rather than dynamic pressure.
The higher the pressures you ramp to e.g. 11 or 12
bar, or the faster the pump acceleration, the more
you might notice this.
You can fine tune the pump PID settings further, but
it's recommended to use the factory settings until
you become familiar with the machines operation.
Grinders.
The Vesuvius is not a cheap machine and the
temptation might be to use a grinder unsuitable for
the machine. To get the most benefit from this
advanced machine use a grinder costing from
approximately 25-50% of the machines value. To
give a real world example, a grinder such as the
Mazzer Super Jolly or similar class grinder
would be the absolute minimum required and
better results will be obtained with more expensive
grinders.
The Vesuvius is able to use a grind much finer than
standard espresso machines and the less expensive
grinders tend not to grind as well at the finer
settings.
Coffee
To do the Vesuvius any justice at all, coffee must be
fresh. You should know the roast date of the coffee
and only use quality coffee from good roasters.
Ideally the coffee should rest for at least 5 days from
the roast date before being used, Often even
longer. Use the time recommended by your roaster
for resting any specific coffee before use.
