3 Document Scope – Caveats and Clarifications
This manual includes material that both duplicates and enhances the official LaSpaziale
S1 Vivaldi II 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, is considered included in
this document by reference.
This document solely covers the S1 Vivaldi II plus options available and supported by
the vendor and/or other vendors supplied through their 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 15A or 20 Amp Operation
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 VII is available 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 VII has a standard 3-prong AC plug with two parallel
blades and a round ground pin. The 20A VII has a 3-prong plug with two 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 VII. A 20A circuit with normal 15A outlets probably means that
Page 3
S1 Vivaldi II Owner’s Manual
multiple kitchen outlets are on the one 20A circuit. Often this means the refrigerator
outlet. 20A VII owners should contact their electrician if unsure how to proceed.
The internal switch which places the 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 VII owners
note that they see little operational effect when running in this mode.
The 20A VII allows both boilers to operate simultaneously. HOWEVER, it is possible to
place the 20A VII into 15A mode without removing the covers from the machine and
flipping the internal mode switch. This is called ECONOMY mode and is described later
in this manual.
As a temporary solution, Economy mode is a great option for those that really want the
20A machine but that do not currently have a 20A circuit. However, 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. It is also available elsewhere or you can make your own with a
quick trip to your local hardware store.
Locating/Changing the 15A / 20A Mode Switch
1. The Vivaldi 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
Page 4
S1 Vivaldi II Owner’s Manual
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.
4.2 Initial Installation Before Connecting Power
After removing the 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 including a rubber backflush disk (not shown).
Page 5
S1 Vivaldi II Owner’s Manual
Tip the 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 VII.
Be sure you connect the included water hose to the threaded water inlet on the bottom
of the machine. Proper connection is obvious since there is only one place it can
attach. The opposite end of the hose - which connects to the water supply - may
require adapters from your local hardware store depending on your specific situation.
Contact your VII dealer for advice if the solution isn’t obvious. Also, your 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 test, contact your VII dealer and discuss the available options.
Once water supply is properly attached, turned on, and the desired basket has been
inserted into one of the portafilter handles, attach the portafilter to the group. Be sure
that the drip tray is installed by sliding it into place at the bottom front of the machine.
4.3 Turning On and Heating the Machine
1) Insert the plug into the 110V AC socket, the On/STBY light (22) starts flashing.
(Stand-by mode).
2) Press the ON / OFF (27) 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).
Page 6
S1 Vivaldi II Owner’s Manual
3) 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.
4) 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.
5) Fasten the portafilter handle (11) to the brewing group (10).
6) 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
continues until the machine has reached its operating temperature (light from
flashing to fixed).
7) 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.
8) 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.
9) The machine is now ready.
WARNING!!
To activate and deactivate the boiler mode press the BOILER (26) button. Every time
you turn on the machine, the boiler is in service.
When the boiler is turned off, it is impossible to use hot water for infusions or steam
delivery.
The machine can also operate in the economy mode (see relative paragraph).
4.4 Espresso Brewing
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 (aprox 7g for a single or 14-15g
for a double), 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.
4.5 Volumetric Dose Programming
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
Page 7
S1 Vivaldi II Owner’s Manual
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
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.
4.6 Hot Water Delivery
(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
4.7 Steam Delivery
(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. Turn the steam knob (6) counter-clockwise, regulating the steam flow according to
the need.
3. At the end of the heating phase of the drink, stop the steam delivery by turning the
steam knob (6) clockwise
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.
Page 8
S1 Vivaldi II Owner’s Manual
WARNING!!
Do not turn the steam knob (6) before placing the steam wand (2) inside
the pitcher, in order to avoid burns.
4.8 Economy / Boiler Operational Modes
On the 20 Amp models of the LaSpaziale VII, the BOILER button performs two
standard roles:
1. Turning the Steam boiler on and off
2. Entry and exit of Economy mode
There are three possible operational modes of the two boilers in the La Spaziale VII 20A
model:
1. 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.
2. 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.
3. The BOILER button can also be used to switch in and out of Economy mode. In
this mode only one boiler can be on at a time. The 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.
4. Turning the Steam/Hot Water Boiler On and Off
1. The VII must be in ON mode, not Standby for all operations below.
2. Momentarily press the BOILER button
3. The Boiler lamp turns off. Neither steam nor hot water is available.
Note: if you turn the VII Off then On again, or if power is removed and restored to
the VII, the Boiler returns to the On state.
4. Momentarily press the BOILER button again.
5. The BOILER lamp is on (or blinking). Steam and hot water are available.
Turning Economy Mode On and Off
5. The VII must be in ON mode, not Standby for all operations below.
6. Press the BOILER button for 10 seconds until the ECON lamp illuminates.
Economy mode is now active.
Note: if you turn the VII Off and On again or if power is removed and restored to
the VII, Economy mode remains active until you perform step 4, below.
7. While in Economy mode you can momentarily press the BOILER button to
completely turn off the boiler. Another momentary press returns you to Economy
mode.
Page 9
S1 Vivaldi II Owner’s Manual
8. To exit Economy mode, press and hold the BOILER button for 10 seconds until
the ECON lamp is extinguished.
4.9 V1/VII Mode Switch
The VII Controller board actually has a backward compatible mode that emulates the
functionality of the original VI. None of the advanced features of the VII are available
when the controller is in VI mode. If you don’t seem to be able to access the VII
features, your machine might have inadvertently gotten switched to VI mode. If in doubt
as to which mode you are in, just unplug the VII and then plug back in to see if the three
yellow or three green lamps blink once. Yellow = VII mode and Green = VI mode.
With the VII in Standby mode (ON/STBY blinking green), press and hold the Hot Water
button for at least 10 seconds. If three yellow lights blink once your machine is now in
VII mode. If three green lights blink once the machine is now in VI mode. Each time
you hold in the Hot Water button for 10 seconds while in Standby (ON/STBY blinking
green), the mode toggles.
Note that if you change from VII mode and then back again all the V2 specific settings
are lost and must be reset.
4.10 Espresso Group Water Temperature Regulation
4.10.1 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
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.
4.10.2 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
Page 10
S1 Vivaldi II Owner’s Manual
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
4.10.2.
To Which Machines Do These Instructions Apply?
Instructions are given in the two sections below both. This first is for machines with the
original offset adjustment. The section that follows is for machines with the extended
temperature offset adjustment. In general if you purchased a new VII from Chris Coffee
after 7/1/2008 or if you know that you upgraded your older machine after that date, then
the extended offset instructions should apply.
If you are unsure, try both methods outlined below. Only one will work and then you’ll
know which version you have.
4.10.2.1
Standard Temperature Offset Adjustment
With the machine in Standby (only ON/STBY green lamp blinking), press the BOILER
button until the green ON/STBY lamp and the red BOILER lamp are blinking (about 10
seconds).
If the Offset = 0ºC, then no other lamps are lit. Assuming a start with Offset = 0ºC ,
each press of the BOILER button, changes the offset by -1ºC and lights an additional
lamp starting with the 91ºC lamp and going up through the ECON lamp. Once all eight
offset lamps are lit, an additional press of the BOILER button cycles back to 0ºC offset.
To exit the Offset mode, press ON/OFF (machine in Standby – ON/STBY blinking).
When entering the Offset mode the next time, the last stored value is displayed.

4.10.2.2
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 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
by all temperature lamps off. A -8˚C offset is designated by all temperature lamps plus
ECON 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
Page 12
S1 Vivaldi II Owner’s Manual
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.

4.10.3 Extreme Temperature Set Function
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
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.
Page 13
S1 Vivaldi II Owner’s Manual
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 Econ (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
Notes:
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 88ºC, then later change the temperature to 93C, the next
time you select 91ºC, you will get 91ºC, not 88ºC. If you wish to obtain 88ºC
again you will need to follow the above instructions to reprogram in the 3ºC
decrease.
4.11 Programmable Preinfusion
Note: only machines purchased or upgraded after 7/1/08 have this feature.
With the machine on (ON/STBY (22) lit and not blinking), press and hold the ON/OFF
button(27) for three seconds until the ON/STBY (22) and the current preset temperature
lamps are both blinking. Then press the BOILER button (13) for 3 seconds. The
temperature plus ECON lamps now display the current time delay between when the
Page 14
S1 Vivaldi II Owner’s Manual
group water solenoid opens and when the pump is activation. This is the preinfusion
time. If none of the lamps 14-21 are lit, the preinfusion time is 0 seconds which means
no preinfusion. Each press of the BOILER button (13) increases preinfusion time by 1
second and lights one more lamp up to a maximum of 8 seconds when all of the
temperature and ECON lamps (14-21) are lit. When preinfusion is set to 8 seconds,
another press of the BOILER button (13) resets the preinfusion back to 0 seconds.
Once the preinfusion time is set as desired, press the ON/OFF button (27) to exit the
programmable preinfusion mode.
This feature should be coupled with an external pressure regulator plus a pressure
gauge. Chris Coffee recommends an initial setting of 20-25PSI (~1.5bar) of input water
pressure and 2-3 seconds of preinfusion time. Other articles on programmable
preinfusion suggest a higher input pressure of around 45psi (3 bar). Feel free to
experiment with both settings to optimize your espresso experience.
5 Alarm Handling
The VII uses computerized sensors to robustly handle VII device malfunctions. There
are two types of alarms the 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 Coffee Group Water Dosing System Failure
This is a non-blocking alarm. 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 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.
5.2 Coffee Group Temperature Detection System Failure
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 VII and request service.
Page 15
S1 Vivaldi II Owner’s Manual
5.3 Steam Boiler Temperature Detection System Failure
(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 VII and request service.
5.4 Damaged Group Heating Element Triac
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 VII and request service.
5.5 Damaged Boiler Heating Element Triac
(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 VII and request service.
5.6 Boiler Automatic Refill System Failure
(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 VII can be operated with the steam boiler off until repairs to the boiler
function occur.
Factoid: A triac is a device to which a small DC control voltage can be applied in
order to turn on a large AC current source. One is used for each boiler in the VII.
Think of a triac as a solid state semiconductor equivalent of an electromechanical relay. TRIAC is an acronym for Triode for Alternating Current.

8 Adjustments and Maintenance
8.1 External VII Surface Cleaning
Use a damp sponge and wipe dry with a soft cloth. Alternately, window cleaner wiped
off with a dry soft cloth works well.
8.2 Routine Group Cleaning
The extra pair of shower screens was not included with your VII so you'd have an extra
set. They are included as part of LaSpaziale’s recommended cleaning regimen which is
targeted at light commercial use where there is no time for a complete detergent based
back flush routine. The reason for LaSpaziale’s double shower screen arrangement is
to trap grounds between the screens so that the 3-way valve rarely, if ever, needs a
detergent cleaning.

With the VII on and fully heated, use the included key wrench to remove the
shower screen bolt.

Drop out the two screens and the dispersion disk.

Use the included plastic handled wire brush to quickly scrub the group head
while water is running through the group to flush out the particles. (This is why
the long handled brush - to keep your hands away from hot water.)

Also, give the dispersion disk a quick scrub.

Reassemble using the other set of screens.

Soak the original set of screens in Cafiza, Joe Glo, or similar detergent, scrub,
rinse, and put away for next time.
The Way Most Mini V2 Users Actually Do It:
As noted above the official LaSpaziale method was developed assuming the machine is
in light commercial use. This is certainly not the target market for the Mini V2. Here is
how most users clean their coffee group:
Start with the basic procedure above, though most folks use something like a
Pallo brush rather than the wire brush that came with the machine for the 3rd
step. Once the clean screens and dispersion disk are back in the machine
perform the following steps.
Using 1/3 tsp Cafiza, Joe Glo, or similar detergent every 2-4 weeks is plenty
for home use. Backflush the S1 Vivaldi II Mini more often with plain water.
Place the backflush disk in the double basket with 1/3 tsp of Cafiza powder.
Press the single cup button. In 5-10 seconds the three yellow LEDs will start
to blink.
Press the single cup button again to stop the pump which automatically
engages the 3-way valve. (The three yellow LEDs normally come on when
Page 21
S1 Vivaldi II Owner’s Manual
you grind too fine and choke the machine. So the instant this condition is
sensed is the ideal point at which to engage the 3-way valve.)
Perform the above cycle 5 times waiting about 30 seconds between each
cycle.
Then rinse the remaining detergent from the basket and replace the portafilter
with the backflush disk still installed.
Backflush for 5 more cycles to rinse the remaining residue from the group and
3-way valve.
Remove the backflush disk, make shot of espresso and throw it out.
Important Tip: To maximize the effectiveness of the cleaning process and
minimize how often a detergent cleaning is required, after every series of shots is
pulled, run a shot with the PF remove. Scrub the screens and around the gasket
with a Pallo brush while the hot water is exiting the group. This will flush most of
the grounds and sediment into the drip tray.
NOTE: The following are advanced maintenance
and adjustment procedures. Do not perform
them without the proper tools and confidence
that you can do them properly. When in doubt
always contact your VII dealer first.
Page 22
S1 Vivaldi II Owner’s Manual
8.3 Group Pressure Test and Adjustment
This adjustment and the one covered in the next section require that use of a Portafilter
with the rubber disk or blind filter basket. (The same one used for back flushing.) For
clarity the portafilter is not shown in the photo but it MUST be used.
Removal of the chrome panel behind the portafilter is required. This is the panel
through which protrudes the boiler/group pressure gauge. Use a large Phillips
screwdriver to remove the two screws adjacent to the numbers (5) on the diagram on
page 2. Then remove the panel. Attach the portafilter with rubber disk or blind basket.
The adjustment screws are designated by the letters “A” and “B” in the diagram below.
First, loosen the lock nut “A” (14mm wrench). Press the Single Cup (24) or Double
Cup (25) button and wait for the group pressure gauge “D” to stabilize. Most users
prefer group pressure in the range 8.2-9.0 bar. Turning the adjuster nut “B” (10mm
wrench) counter-clockwise lowers the pressure, turning it clockwise increases the
pressure. When it is set to your preferred pressure, tighten the lock nut and recheck.
Then reattach the front panel. Should your water supply pressure change significantly,
readjustment will be required as the rotary pump supplies an adjustable boost to the
supply pressure. However, if you add an in-line pressure regulator to the water supply
line this should not be required. If your water supply pressure is higher than 30psi, a
water pressure regulator can also reduce or eliminate expansion valve drips.
Page 23
S1 Vivaldi II Owner’s Manual
8.4 Expansion Valve Release Adjustment
This procedure starts by removing the chrome front panel as in the above procedure
and also requires the portafilter with rubber disk or blind filter basket.
1. Adjust the group pressure to 12.5 bar per the following instructions:
a) Loosen lock nut "A" using the 14mm wrench
b) Tighten nut "B" 1-2 turns using the 10mm wrench
c) Turn on pump until pressure on the Group Pressure gauge “D” stabilizes
d) Repeat steps b & c until pressure reads 12.5 bar
2. The expansion valve “C” should open at 12.5 bar
3. If no water is dripping or running from the tube below nut "C" at 12.5 bar the
expansion valve is set too high. Use the 21mm socket to loosen nut "C" (rotate
counter-clockwise as viewed from the bottom of this valve) until the valve just opens
when running the pump as the pressure reaches 12.5 bar.
4. If water is pouring out of tube below "C" before the pressure hits 12.5 bar, use the
21mm socket to tighten nut "C" (rotate clockwise and viewed from the bottom of this
valve) until the valve is just opening at this pressure. If you back off the PF pressure
to 12 bar all dripping should stop - though it may take a minute or two for residual
moisture to drip out.
5. Once you are convinced that the expansion valve is properly calibrated, readjust the
rotary pump pressure by unscrewing "B" to reach your preferred pressure - normally
in the range of 8.2 to 9.0 bar. Then tighten lock nut "A".
Notes:
1) Make small adjustments, then turn the pump on and check. Don't attempt any
of these adjustments while the pump is on.
2) The term expansion valve is somewhat of a misnomer as this device is really the
overpressure valve for the group boiler. The steam boiler has its own dedicated valve.
