3 Basic Machine Operation
(BOLD = lamps, Reverse = buttons, numbers in parentheses reference to above table)
3.1 15A or 20 Amp Operation
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
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
wapping out your standard 15A outlet with a 20A outlet. These are readily available

3) The light corresponding to the set temperature starts flashing to indicate that t
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

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
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 t
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).

3.4 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, 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.
3.5 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
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 Cupbutton (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.
Page 5

S1 Vivaldi II Owner’s Manual
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.
3.6 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
3.7 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.
WARNING!!
Do not turn the steam knob (6) before placing the steam wand (2) inside
the pitcher, in order to avoid burns.

3.10 Espresso Group Water Temperature Regulation
3.10.1 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.
3.10.2 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,

how to tell what your current offset is, you can find out by
the temperature setting shown by the temperature lamps on the front panel may differ
from the water temperature at the group eally, most users would prefer that the

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

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.
3.10.2.1 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
of the BOILER button cycles back to 0ºC offset.offset lamps are lit, an additional press
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.

3.10.2.2 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
N
f
temperature lamps off. A +8˚C offset is designated by all temperature lamps plus ECO
on (Low Water on VII Mini). If your positive offset is more than you wish, each press o
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
is
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. Th

3.11 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

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
en all of thesecond and lights one more lamp up to a maximum of 8 seconds wh
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
auge. Chris Coffee recommends an initial setting of 20-25PSI (~1.5bar) of input water
time. Other articles on programmable
reinfusion suggest a higher input pressure of around 45psi (3 bar). Feel free to
xperiment with both settings to optimize your espresso experience.

7 Adjustments and Maintenance
.1 External VII Surface Cleaning
7.2 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.

water pressure regulator can also reduce or eliminate expansion valve drips.
