3 Document Scope – Caveats and Clarifications
This manual includes material that both duplicates and enhances the official LaSpaziale
S1 Mini Vivaldi Instruction Manual in key areas. However, it does not duplicate the
detailed and very important information covering machine certifications or ratings nor
does it repeat all the warning and safety information contained on the “lawyer” pages.
That information, as contained in LaSpaziale Instruction Manual Part # LSC 014-UK
Rev.00 or later, is considered included in this document by reference.
The official LaSpaziale S1 Mini Manual covers the Mini Vivaldi I and the Mini Vivaldi II
plus one option not currently offered or required in the consumer market. That option, as
well as material intended specifically for the Mini Vivaldi I, has been omitted from this
document.
This document solely covers the S1 Mini Vivaldi II plus options available and supported
by Chris Coffee Service and/or other vendors supplied by Chris Coffee Service through
its exclusive distribution agreements with La Spaziale S.p.A.
4 Basic Machine Operation
(BOLD = lamps, Reverse = buttons, numbers in parentheses reference to above table)
4.1 15Amp or20AmpOperation(READMEFIRST)
Please read this section first, especially if you purchased the 20A version of the
LaSpaziale VII Mini but do not currently have an available 20A outlet.
The LaSpaziale Mini VII can be purchased in 15A and 20A versions. In actuality, they
are both identical machines. There is an internal switch that selects the operating mode
and they have different power cords installed. The power cord is the easiest way to tell
which version you have. The 15A Mini VII has a standard 3-prong AC plug with two
parallel blades and a round ground pin. The 20A Mini VII has a 3-prong plug with two

S1 Mini Vivaldi II Owner’s Manual
Page 5
perpendicular blades and a round ground pin. The 20A version therefore requires a
20A circuit which has a special 20A outlet which accepts the 20A plug.
Most modern kitchens have 20A circuits. However, they often do not use 20A outlets
because multiple outlets may be on the same 20A circuit. If you have a 20A circuit with
a 20A outlet this most likely means that outlet has its own dedicated 20A circuit and is
safe to use with the Mini VII. A 20A circuit with normal 15A outlets probably means that
multiple kitchen outlets are on the one 20A circuit. Often this means the refrigerator
outlet. 20A Mini VII owners should contact their electrician if unsure how to proceed.
The internal switch which places the Mini VII in 15A mode does so by never allowing the
group boiler and the steam boiler to operate at the same time. When the thermostats
for both boilers try to turn on at the same time, the group boiler always has precedence,
and then the steam boiler operates in sequential fashion. A number of 15A Mini VII
owners note that they see little operational effect when running in this mode.
The 20A Mini VII allows both boilers to operate simultaneously. HOWEVER, it is
possible to place the 20A Mini VII into 15A mode by removing the top cover from the
machine and flipping the internal 20A/15A mode switch. This is often referred to as
“Economy Mode”.
Economy mode is a great option for those that really want the 20A machine but that do
not currently have a 20A circuit. In addition to flipping the mode switch from 20A to 15A
operation, this will require swapping out your standard 15A outlet with a 20A outlet.
These are readily available from most hardware stores. For a more temporary solution
there is an alternative such as this adapter cable available from Chris Coffee Service:
http://www.chriscoffee.com/products/home/espressoaccs/20t015adaptorplug. It is also
available elsewhere or you can make your own with a quick trip to your local hardware
store.
Note: new machines use a dual Solid State Relay (SSR) rather than the triac.
4.2 OptionalOn/OffTimerAccessory–OverviewandWARNING
The S1V2 has an optional On/Off Timer that can be purchased which provides the
capability for up to 3 On/Off cycles per day with a different program for all 7 days of the

S1 Mini Vivaldi II Owner’s Manual
Page 6
week, if so desired. Each new machine has the cable needed to plug this timer into
cable tied into place just behind the front panel. More information including the
installation manual can be found here:
http://s1cafe.com/s1v2/images/Vivaldi%20Timer%20Instructions.pdf
There is a switch labeled ON / OFF on top of the controller box adjacent to the 15A/20A
switch . This switch must be set to OFF if you do not have the Timer plugged in and it
must be set to ON when the timer is installed. Also, the state of this switch is only
sensed when the power cable is unplugged, then plugged back in. So if you need to
change this switch you will need to unplug the machine for at least 5 seconds after you
do so.
WARNING: If you do NOT have the Timer installed but you have the switch set to ON,
the pump will not come on when you try to pull a shot.
4.3 InitialInstallationBeforeConnectingPower
After removing the Mini VII from its packing carton and setting it on the counter, check
for additional installation instructions that may be included. You should also have all the
accessories shown in the photo below plus a rubber backflush disk (not shown).
Tip the Mini VII on its side. Twist all four rubber feet (3) hand tight as they may vibrate
loose during shipping. While performing that task, use a screwdriver to ensure that the
four screws on the bottom (two on each side between the rubber feet) which fasten the
two side panels (5) to the chassis bottom are tight. These steps will help ensure the
quietest possible operation of your Mini VII.
Important Tip: Your Mini VII dealer may request that you check that your water
hardness is below a certain level to ensure long life and trouble free operation.
Hardness test strips may be included for this purpose. If your water fails this

S1 Mini Vivaldi II Owner’s Manual
Page 7
test, contact your Mini VII dealer and discuss the available options. This test
should be done before using your machine. Water over 3 grains of hardness
needs to be softened or else consider using bottle water. Hard water will require
frequent descaling which is not a trivial procedure on this machine. Over time
use of very hard water could result in the need to replace the steam boiler heater
element. Since the VII Mini has a sealed boiler, replacement of the entire boiler is
required. This is not an inexpensive repair. Be forewarned. Use soft water.
4.4 FillingtheWaterTank
1) Remove the drip tray (1)
2) Remove the water tank (4) and fill with soft water to ensure against mineral
buildup in your boilers
3) Replace the water tank (4) and the drip tray (1)
4) Insert the plug into the 110V AC socket, the On/STBY light (22) starts
flashing. (Stand-by mode).
5) Press the ON / OFF (27) and Hot Water (23) buttons simultaneously. During
this stage, the control lights EMPTY and On/STBY (22) blink while the pump
runs
6) Once you see water coming from the group (10), release both buttons. The
unit is now in Standby mode with the On/STBY light blinking. You have now
primed the pump and filled both boilers with water.
Important Tip: The above procedure is only required on the initial use of the
machine or any time when starting up with empty boilers such as after storage,
boiler clean out, shipment, etc. or any time the boilers have previously been
drained. Otherwise, once this procedure is performed once, it is only necessary
to turn the machine on using the ON / OFF (27) button. It is NOT required to
perform the above procedure each time the water tank is refilled.

4.5 TurningOnandHeatingtheMachine
1) Place the desired coffee basket (Single or Double) into one of the portafilter
handles and attach it to the group.
2) Insert the plug into the 110V AC socket, the On/STBY light (22) starts flashing.
(Stand-by mode).
3) Press the ON / OFF (27) and button and keep it pressed for about 3 seconds,
the green On/STBY light (22) changes from flashing to steady indicating the
machine is ON. At the same time the lights from (14) to (21) turn on steadily for
about a second (indicating power on test mode).
4) The light corresponding to the set temperature starts flashing to indicate that the
group is heating and the automatic boiler refill starts until the water level preset
by the manufacturer is reached.
5) Once the filling process is finished, the BOILER light (13) starts flashing to
indicate that the boiler is heating. However, after first switching on, the boiler
doesn't work until the group has reached the set temperature.
6) Fasten the portafilter handle (11) to the brewing group (10).
7) Wait until the set temperature is reached, by checking that the lights on the
control panel (9) gradually turn on as the temperature rises. The visualization
starts as soon as the temperature reaches 91°C (turning on of light 14) and

S1 Mini Vivaldi II Owner’s Manual
Page 9
continues until the machine has reached its operating temperature (light from
flashing to fixed).
8) When the group has reached the set temperature, the boiler heating starts
(BOILER light (13) flashing), once it reaches the set temperature the light
becomes fixed.
9) Every time the group temperature or the boiler temperature drops under the set
value, the respective light starts flashing (heating phase) until the set
temperature is reached.
10)The machine is now ready.
Important Tip: To activate and deactivate the boiler mode press the BOILER (26)
button. When the unit it turned off, then back on or even unplugged, then
plugged back in, the Mini VII will remember the last state of the Boiler mode.
When the boiler is turned off, it is impossible to use hot water for infusions or
steam delivery.
4.6 EspressoBrewing
1. Unfasten the portafilter handle (11) from the brewing group (10) and insert the filter
for one or Double Cups. Fill it with ground coffee, making sure not to leave coffee
powder on the upper edge of the portafilter handle (11), and press it with the
suitable coffee tamper provided.
2. Firmly attach the portafilter handle (11) to the brewing group (10).
3. Place one or Double Cups under the portafilter handle (11).
4. Press the button corresponding to Single Cup (24) if you want to make one coffee
or Double Cups (25) to start the delivery. Once the desired quantity of coffee
programmed is reached, the delivery automatically stops.
4.7 VolumetricDoseProgramming
The programmable volumetric dosing feature allows programming of the Single Cup
(24) and Double Cup (25) buttons to dispense whatever quantities of espresso the
user desires. Their use for single cup and double cup quantities is merely a
suggestion. Many users only pull double shots and program the double shot button for
1.5-2.0oz for that purpose. Then they program the Single Cup button for a larger
amount for use in flushing the portafilter basket and/or the group between shots. The
beauty of the programmable dosing feature is that the machine owner can be creative.
The following are the instructions for programming each button assuming they are
being used for single and double shots.
1. With the machine on, press the ON//OFF (27) button and keep it pressed for about
3 seconds; the control light (22) and the one indicating the set temperature start
flashing.
2. Insert the single cup basket into the portafilter handle (11) and fill it with 7-8g of
ground coffee making sure not to leave coffee powder on the upper edge of the

S1 Mini Vivaldi II Owner’s Manual
Page 10
portafilter handle, and press it with the included plastic tamper or, more optimally, a
high quality 53mm coffee tamper.
3. Fasten the portafilter handle (11) to the brewing group (10), placing a cup under the
portafilter handle.
4. By pressing the Single Cup button (24) the delivery starts and the lights 14-15-16
turn on to show that the one shot espresso dose is being programmed.
5. When the coffee inside the cup has reached the desired quantity, again press the
button (24) to stop the delivery.
6. You automatically return to the initial visualization.
7. Repeat the previous steps above using the Double Cup button (25) making sure
you change the filter inside the portafilter handle (11) to the double shot basket and
fill it with 14-16g of espresso first.
4.8 HotWaterDelivery
(only possible with the boiler turned on, BOILER light 13 on)
1.Place the pitcher below the hot water output (28):
2.Press the Hot Water delivery push-button (23).
3.The hot water delivery starts.
4. Once the desired quantity is reached, stop the delivery by pressing the Hot Water
button (23) again.
Important Tip: The steam/hot water boiler on the V2 Mini is not very large. When
using it for hot water, it is suggested that no more than ~6oz be removed at a time
and then let the unit refill the boiler before using again. Otherwise, you run the
risk of exposing the steam boiler heater element while it is powered up and
possibly damaging it.
4.9 SteamDelivery
(only possible with the boiler turned on, light 13 turned on)
1. Insert the steam wand (2) in the pitcher containing the drink to be heated.
2. Push the steam lever (6) up, regulating the steam flow according to the need.
3. At the end of the heating phase of the drink, stop the steam delivery by pulling the
steam lever (6) all the way down.
4. Remove the pitcher from the steam wand (2) and wipe the steam wand and tip
immediately with a clean, damp sponge in order to remove all residue of the heated
drink.
5. NOTE: The steam lever (6) will remain in the all the way up position when released.
However, if released in any other position, the lever will automatically drop to the off
position.
Important Tip: Do not engage the steam lever (6) before placing the
steam wand (2) inside the pitcher, in order to avoid burns.

4.10 BoilerOperationalModes
There are three possible operational modes of the two boilers in the LaSpaziale Mini VII
20A model:
Both boilers are completely independent, turning on and off according to the
needs of each. Both can be on at the same time. This is the default mode with
the BOILER enabled and 20A mode selected using the internal 15A/20A switch.
The BOILER button can toggle the Boiler on and off. This mode is useful for
those that only drink espresso and do not need steam or hot water and want to
conserve energy. This can be used to keep the boiler off regardless of whether
the machine is running in 15A or 20A mode.
Important Tip: The state of the BOILER button is kept in memory and is
maintained through On/Stby cycles, when the unit is unplugged, or if there
is a power failure.
The Mini VII can also be switched into Economy (15A) mode. In this mode, only
one boiler can be on at a time. The Mini VII automatically controls which is on
according to demand with preference going to the group boiler. This is useful for
those owning the 20A model but lacking a 20A circuit. How to do this is
described below.
Turning the Steam/Hot Water Boiler On and Off
1. The Mini VII must be in ON mode, not Standby for all operations below.
2. With the BOILER lamp on, press and hold the BOILER button until the BOILER
lamp turns off. Neither steam nor hot water is available.
As noted above, the Mini V2 remembers the current state of the BOILER
button through Off/On cycles, when the machine is unplugged, and through
power failures.
3. Press the BOILER button again until the BOILER lamp turns back on.
4. When the BOILER lamp is on (or blinking), steam and hot water are available.
Turning Economy (15A Mode) On and Off
1. The Mini VII must be unplugged and allowed to cool down first.
2. Remove any cups from the cup warming tray (7)
3. Remove the single screw in the front middle of the cup warming tray (7) as
shown in the photo below

S1 Mini Vivaldi II Owner’s Manual
Page 12
4. From the front of the machine look down into the top of the machine. In the right
rear of the machine you will see a toggle switch with its positions labeled 15 and
20. Reach down with the same screwdriver you used to remove the cup warming
tray and flip the switch to the desired position.
4.11 EspressoGroupWaterTemperatureRegulation
4.11.1 Standard Temperature Adjustment
1. When the machine is On (ON/STBY solid green), press the button ON/OFF (27)
and keep it pressed for 3 seconds, the control light (22) and the one concerning
the set temperature start flashing. For example, if the set temperature is 95°C,
light (18) starts flashing.
2. In order to change the operating temperature, press and release the Hot Water
button (23); every press of the button corresponds an increase of the
temperature of 1°C (with the flashing of the corresponding light). When the

S1 Mini Vivaldi II Owner’s Manual
Page 13
maximum temperature of 97°C (20) is reached, the selection restarts from the
minimum temperature of 91°C (14) (cyclic mode).
3. Once you choose the desired temperature, in order to lock in this value, press
the ON/OFF (27) button, the machine will then go back to its normal functioning.
The value of the operating temperature of the machine is easily changed in order to
improve the final result in the cup depending on the coffee blend used and the user’s
personal preference.
4.11.2 Offset Temperature Adjustment
What Does Temperature Offset Do? / How Do I Use it?
The Vivaldi group design exhibits a temperature drop between where the group boiler
temperature probe is located and where the hot water exits the group. Consequently,
the temperature setting shown by the temperature lamps on the front panel may differ
from the water temperature at the group. Ideally, most users would prefer that the
temperature indicated by the temperate lamps exactly matches the water temperature
exiting the group. LaSpaziale has partially accounted for this in its basic design.
However, there are too many machine to machine electrical and mechanical variances
for this to be completely effective. That’s where the temperature offset comes in. The
programmable temperature offset allows a user with accurate group temperature
measuring equipment to enter an offset in the range of ±8˚C (for extended offset option
or 0 to -8˚C for standard offset option) in order to allow their machines temperature
lamps to exactly match the water temperature exiting the group.
Those purchasing new machines from Chris Coffee Service have had the temperature
offset professionally programmed used a Scace device. However, for those obtaining
the expanded offset capability via an upgrade, it is recommended that you note the
current offset prior to upgrading and then duplicate that offset using the instructions
below. If you do not know how to tell what your current offset is, you can find out by
entering the temperature offset mode and then following instructions in paragraph
4.11.2.
4.11.2.1 Extended Temperature Offset Adjustment
Start with the machine in Standby mode (ON/STBY blinking green). Press and hold the
BOILER button for about 10 seconds until the Boiler light and the ON/STBY light start
flashing. You are now in the temperature offset programming mode.
To enter a positive temperature offset between 0˚C and +8˚C push the Single Cup
button. Each press will change the offset by +1˚C. An offset of 0˚C is designated by all
temperature lamps off. A +8˚C offset is designated by all temperature lamps plus ECON
on (Low Water on Mini VII Mini). If your positive offset is more than you wish, each
press of the Double Cup button changes the offset by -1˚C.
To enter a negative temperature offset between 0˚C and -8˚C mode push the Double
Cup button. Each press will change the offset by -1˚C. An offset of 0˚C is designated

S1 Mini Vivaldi II Owner’s Manual
Page 14
by all temperature lamps off. A -8˚C offset is designated by all temperature lamps plus
EMPTY on. If your negative offset is more than you wish, each press of the Single Cup
button changes the offset by +1˚C.
How Do I Tell If My Current Offset is Negative or Positive?
Example: You enter Offset Programming mode and see that three lamps are on. This
can indicate either ±3˚C. Which is it? Since each press of the Double Cup button
changes the offset by -1˚C, press it and see what happens. There will either be two or
four lamps lit. If four lamps are lit the offset must have been -3˚C since pressing
Double Cup always changes the setting by -1˚C with each press. If two lamps are lit
the offset was +3˚C. By pressing Double Cup the offset has changed to +2˚C.
-8 -7 -6 -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 +6 +7 +8 ˚C Offset
----------------------------------------------------------Single Cup Button
--------------------------------------------------------- Double Cup Button
Note that neither the Single Cup nor the Double Cup button presses wrap around
when they reach the limit of their range. Once you get to +8˚C additional presses of the
Single Cup button do nothing. Same with the Double Cup button once -8˚C is reached.

4.11.3 ExtremeTemperature SetFunction
Standard temperature programming described in section 4.10.1 allows a range from
91ºC to 97ºC in 1ºC increments. There may be times when the user desires a
temperature outside of this range. While the Offset mode described in section 4.10.2
could be used for this purpose, it is best to use the offset as intended. Once set

S1 Mini Vivaldi II Owner’s Manual
Page 15
properly, the offset should be left alone. Instead, the VII Mini includes a mode
specifically for use in extending the temperature range above 97ºC or below 91ºC up to
a max of 3ºC. While the ability to extend the temperature above 97ºC is of limited use,
there are some types of coffee whose flavor is optimum in the 88ºC to 90ºC range.
Note that the method below only works if the master temperature is set to either
91ºC or 97ºC. If the temperature is set to 91ºC you can only use the instructions
below to lower the temperature by 1ºC, 2ºC, or 3ºC. If the temperature is set to
97ºC you can only use the instructions below to raise the temperature by 1ºC, 2ºC,
or 3ºC. Consequently you must use the instructions provided in section 4.10.1 to
set the master temperature to 91ºC or 97ºC BEFORE using the instructions below.
If this is not done, the instructions below for entering the Extreme Temperature
Set mode will work as described, but once in that mode attempting to a raise or
lower the temperature has no effect.
Instructions for programming this mode AFTER setting the master temperature to 91ºC
or 97ºC are:
Start with the machine in Standby mode (ON/STBY light flashing).
Press and hold the Two Cup button for ~3 seconds until lights 94ºC (17) and
95ºC(18) come on indicating that the Extreme Temperature Function setting
mode is active.
If you start with the master temperature set to 97ºC, each time that the Hot
Water button is pressed, lights 96ºC (19), 97ºC (20), and Tank Low (21) will
switch on in succession. Each light indicates a 1ºC increase. All three lights on =
100ºC.
If you start with the master temperature set to 91ºC, each time that the One Cup
button is pressed, lights 93ºC (16), 92ºC (15), and 91ºC (14) will switch on in
succession. Each light indicates a 1ºC decrease. All three lights on = 88ºC.
Press the Two Cup button again to exit Extreme Temperature set mode and
return back to Standby mode
Note:
When you change the temperature of the 91ºC and/or 97ºC buttons
according to the above instructions, the change only remains in effect until
the temperature is changed. For example, if you change the 91ºC selection
by 3ºC to yield 88 ºC, then later change the temperature to 93C, the next
time you select 91ºC, you will get 91ºC, not 88 ºC. If you wish to obtain
88ºC again you will need to follow the above instructions to reprogram in

5 Alarm Handling
The Mini VII uses computerized sensors to robustly handle Mini VII device malfunctions.
There are two types of alarms the Mini VII can generate:
Blocking Alarms –these are the most serious. The VII will turn itself Off and display
the alarm codes noted below when one of these alarms occurs.
Non-Blocking Alarms –These are informational only and, while they do represent an
error condition, the machine will continue to function.
5.1 NoWaterinTank
When the tank (4) is out of water the red EMPTY light (21) comes on and remains on
until at least 1liter of water is added. The tank can hold up to 3 liters.
5.2 CoffeeGroupWaterDosingSystemFailure
When the flow meter isn't working properly or when the coffee grind is too fine, this is
indicated by the turning on of the lights 14-15-16; if you are making one coffee dose,
and the lights 17-18-19 if you are making two coffee doses.This is a non-blocking
alarm. This alarm is actually useful when back flushing as an indication of when to turn
off the pump and allow the 3-way valve to operate.
5.3 CoffeeGroupTemperatureDetectionSystemFailure
This alarm is a blocking one, and occurs when the temperature probe of the group is in
short circuit (temperature >145°C) or is in open circuit (disconnected) condition
(temperature <60°C). The lights 20-21 turn on.
If the group water temperature does not exceed 60°C within 5 minutes of turning the
unit on, this alarm will also occur.
Turn off the Mini V2 and request service.
5.4 SteamBoilerTemperatureDetectionSystemFailure
(only with the boiler turned on)
This is a blocking alarm and occurs when the temperature probe of the boiler is in short
circuit (temperature >145°C) or it is in open circuit (disconnected) condition
(temperature <60°C). The lights 19-20-21 turn on.
The alarm can be temporarily cleared by turning the boiler off (Press BOILER (26)
button.) Eventually you will need to turn off the Mini V2 and request service.
5.5 DamagedGroupHeatingElementTriac/SSR
This alarm is a blocking one, and occurs when the group triac always remains in
conduction (temperature >140°C). The lights 20-21 are flashing.
Turn off the Mini V2 and request service. Note: new machines use a dual Solid State
Relay (SSR) rather than the triac.

5.6 DamagedBoilerHeatingElementTriacSSR
(only with the boiler turned on)
This alarm is a blocking one, and occurs when the boiler triac always remains in
conduction (temperature >140°C). The lights 19-20-21 are flashing.
Turn off the Mini V2 and request service. Note: new machines use a dual Solid State
Relay (SSR) rather than the triac.
5.7 BoilerAutomaticRefillSystemFailure
(only with the boiler turned on)
This is a blocking alarm which is signaled by blinking of the Boiler (13) light. If the pump
runs for more than 1 minute attempted to refill the boiler without the controller circuit
receiving a boiler full signal, this alarm is triggered.
This alarm can be temporarily cancelled by pressing the BOILER (26) button to turn off
the boiler. The Mini VII can be operated with the steam boiler off until repairs to the
boiler function occur.
