6.1 Filling the boiler
Checking the position of the taps in the water system
a) Remove the coffee ground collection tray with grille. Now, check for the following configuration:
r#PJMFSESBJOUBQDMPTFEr5BQPOUIFBVUPNBUJDMFWFMDPOUSPMWBMWFPQFOr5BQPOUIFBVUPNBUJDMFWFMDPOUSPMWBMWFPQFOb) Install the coffee ground collection tray with grille
c) Open the main water fill tap 33
d) Open a steam delivery lever 5 to allow air to escape from the system as the boiler is filled.
Mod. 85 - Practical - S/E
e) Move the main switch 1 to position 1 to fill the boiler automatically without activating the heating ele-
ments. When the water reaches the probe, the “MAX” led will light up. When the boiler is full, turn the
main switch to working position 2.
Mod. 85 - S/E - 2 - 3 - 4
f) Make sure that the main switch 1 is in position “zero”.
g) Press and hold down the button 14 until the sight glass 20 is 3/4 full.
6.2 Calibration of pump pressure
a) Once the boiler is filled, turn the main switch to position 2 (the heating elements start to heat the water).
b) Press the continuous-feeding push button 19 for the manual serving machines or the push button 10 for
the electronic machines with automatic serving, so that the water flows out of the unit corresponding to
the pressed button.
c) Read the water pressure value on the lower part of the
pressure gauge 18. The optimum pressure is 9 bar.
The pressure is adjusted to the desired value by oper-
ating on the pump screw: the pressure is increased by
turning clockwise; it is decreased by turning counter-
clockwise. As shown in the following figure, there are
three different cases for adjusting this screw, depend-
ing on the pump installed on the machine:
- adjust only the screw
- adjust the screw and lock it with the lock nut
- unscrew the cap nut and adjust the screw.
6.3 Calibration of water pressure in the boiler
a) After having filled the boiler to the proper level, turn the main switch to position 2 (the heating elements
will start to heat the water).
b) Open the lever-controlled steam valve 5 to vent the air during the heating phase. Close the valve as soon
as the steam phase is reached. The steam pressure in the boiler can be read on the upper scale of the
pressure gauge 18 from 0 to 3 bar. The pressure rises to the calibration value of the pressure switch 27
in the range from 0.9 to 1.1 bar. To vary the steam pressure, turn the screw 28 on the pressure switch
27. The pressure is decreased by turning the screw clockwise and it is increased by turning the screw
counterclockwise. The screw is adjusted by means of a screwdriver inserted into the hole on the lid of the
pressure switch. The pressure switch can be reached from the upper tray and grill.
6.4 Heating the water in the boiler
a) Rotate the main switch to position 2.
b) Hold down a steam delivery lever 5 to allow air to escape from the system as the machine heats up.
Release the lever as soon as steam escapes from the delivery pipe. Boiler pressure is indicated on the
0-to-3-bar scale on the pressure gauge 18 (suggested value: 0.9-1.2 bar).

6.5 Electric cup warmer (Optional)
The on/off button 4 is used to heat the cup holding shelf; it can be switched on and off at will.
6.6 Steam delivery
This function is used to deliver steam from the boiler to heat liquids, or to foam milk for cappuccinos. Lower
or raise the lever 5 to obtain the maximum flow of steam. Move the lever sideways to the left of right to obtain
a reduced steam flow.
6.7 Hot water delivery
The lever-operated tap 11 is used to deliver hot water from the boiler for making tea, camomile herb tea, etc.
This lever operates in the same way as the steam delivery lever.
6.8 Preparation of ground coffee
Make sure that the filter with the desired capacity has been installed in the filter holder. After the coffee has
been loaded and pressed into the filter, the coffee level in the filter must just touch the spray head on the
brewing unit. To check for correct coffee level, install the full filter holder onto the brewing unit and then remo-
ve the holder. Now, look at the surface of the coffee: if the level is correct, the coffee will contain the imprint
of the central mounting screw on the spray head of the brewing unit.
6.9 Brewing coffee
Semiautomatic models: 85 - S
Once the filter holder has been installed onto the machine, simply press the switch 19 to actuate the pump
and solenoid valve. When the coffee in the cup has reached the desired level, move the switch back to its
original position to terminate brewing.
Automatic models: 85 - E
Once the filter holder has been installed onto the machine, press one of the five brewing buttons. The first two
buttons 6 and 7 are used to select the two pre-programmed single portions of coffee. The second two buttons
8 and 9 are used to select the two pre-programmed double portions of coffee. The fifth button 10 immediately
shuts down brewing if pressed during a coffee brewing cycle. Button 10 can also be used to brew the desired
quantity of coffee manually: press this button to start brewing, and presse the button a second time to stop
brewing when the desired quantity of coffee has been obtained.
6.10 Draining the boiler
If the boiler must be emptied, shut off the power to the machine by moving the main switch 1 to the “zero”
position. On gas-fired machines, extinguish the flame by closing the gas feed valve. Open the drain tap 21
until the boiler has been completely drained.
mportant: be sure to close the tap before refilling the boiler.
6.11 Automatic operation - programming the coffee brewing cycles
Automatic models: 85 - E
A. Entering the programming mode
Set the main switch 1 on the machine to position “zero” (machine switched off).
Hold down the fifth button 10 on the first brewing unit. Now, rotate the main switch 1 to position 1 (machine
switched on). After a few seconds, release the button 10. The indicator led for the button will now begin to
flash, as will the same led on all the other brewing units. The machine is now ready for programming.
B. Programming
To program the four portions on brewing unit I, proceed as follows: place the single-portion filter into the
single-portion filter holder. Use the coffee dispenser to dispense a single portion of coffee into the filter.
Mount the filter holder onto brewing unit I.
Place an espresso cup under the spout on the filter holder.
Press the first button 6 whose portion is to be programmed. When the coffee in the cup reaches the
desired level, press the fifth button 10 to stop brewing.
Follow the same procedure to program the other portions on each group. Once the four portions on brew-
ing unit I have been programmed as desired, the relative data can be transferred to the other brewing
units by pressing the fifth button 10 on each unit. When each button 10 is pressed, the indicator led for
the button will stop flashing and remain steadily lit. This shows that the data on brewing unit I has been
transferred successfully.

and all the leds will turn off. The programmed quantity of coffee will now be delivered when an automatic
brewing button is pressed.
6.12 Important information on daily maintenance
To keep your espresso machine in top operating condition and obtain maximum performance, the followint
cleaning operations must be performed on the brewing units at the end of the work day:
a) Install the blank filter (without holes) into the filter holder. This filter is provided with the machine.
b) Install the filter holder with blank filter onto the brewing unit to be cleaned but do not tighten the holder,
thus allowing water to overflow at the sides. Push the continuous brewing button and let the water run
for about a minute. This will clean the spray head and the water delivery pipe in the unit.
c) Tighten the filter holder onto the brewing unit so that water can no longer overflow at the sides. Manually
run the unit once again for around 5 seconds, and then shut the unit down. Repeat this operation 5 or 6
times to clean the solenoid valve and the drain pipe on the unit.
/PUFTo clean the brewing units more thoroughly, the blank filter can be filled with one of the special deter-
gents that are available on the market.
6.13 Alarms
A flashing Led on the first button of pushbutton array indicates a malfunction on the flow meter.
A flashing Led on the second button of all the pushbutton arrays indicates a malfunction on the automatic
boiler refill system (jammed solenoid valve, insufficient water from the main water system, etc.). After 1’30”,
the pump motor will shut down.
Note: If the machine shuts down as described above, call your local service technician.

Position the appliance as described in the Use and Maintenance Manual, remove the control panel as de-
scribed in the same handbook, and connect the appliance to the gas supply mains, or LPG bottle (G30/G31),
using rigid metal pipes or flexible metal tubes according to UNI-CIG 9891 Standards.
Check that the appliance is prearranged for the type of gas actually being used; the corresponding setting is
shown on the settings tag.
If the appliance is prearranged for a different type of gas, change the arrangement as described in the para-
graph “Changing the calibration”.
The gas infeed, consisting of an on-off valve (51), includes a G 1/8” threaded connection (thread is not gas-
tight) according to ISO 228-1 Standard.
If using rigid metal pipes for connection to the gas supply, place an appropriate fitting between the valve and
the rigid metal pipe, which should be provided with a G 1/8” female thread (thread is not gas-tight) according
to ISO 228-1 Standard.

31
EN LISH
If using flexible metal tubes for connection to the gas supply, interpose an appropriate G 1/2” female nipple
(gas-tight thread) according to ISO 7-1 Standard and a G 1/2” male nipple (thread is not gas-tight) according
to ISO 228-1 Standard; interpose a suitable gas-tight gasket.
When the connection is completed, open the gas flow upstream of the appliance and, using a soapy solution
(never a free flame), check the perfect tightness of the connection.
7.2 Venting the combustion fumes
In relation to the venting of the combustion fumes, the appliance is of Type A1: i.e., it draws in the air required
for combustion from the room and discharges the fumes in the same environment.
Place particular attention to the volume of the room where the appliance is to be installed: this should be at
least 12 m3.
If the room has a smaller volume, it will be necessary to install the appliance directly under a suction hood,
and also to provide a combustion air intake with a free-flow cross section of al least 100 cm2.
7.3 Ignition
Press and turn the gas valve knob (51) counterclockwise to the position of the flame symbol, as shown in Fig.
B. While holding the knob pressed, push a few times the burner ignition button, marked with the star symbol
(53) to ignite the burner (piezoelectric ignition).
When the flame is lit, check through the relative hole (54), while keeping the gas knob pressed for 5-10 secon-
ds. After this period, if the flame does not remain lit, repeat the ignition operation again.
7.4 Changing the calibration
The appliance is prearranged to operate with the gas indicated in the relative settings tag attached to the
appliance. The information regarding the air setting, injector, rated and reduced heat flow are shown in Tables
1 and 2. The data that correspond with each model are indicated by the next-to-last character of the code for
the relative model. For example, the model code shown on the tag for the gas part characteristic 85-E-3-G
shows number 3 in the next-to-last digit.
In this case, refer to the data shown in Tables 1 and 2, respectively, in the column headed “3 Units”.
If you wish to change the calibration of the appliance, proceed as follows:
Unscrew the primary air adjusting ring nut (55 - Fig. C) to expose the nozzle (56). Using the relative wrench,
unscrew the nozzle (56) and replace it with the proper one indicated in Table 2, checking that the diameter
marked on the same nozzle corresponds to the right diameter.

Screw on the new nozzle (56), and position the primary air adjusting ring nut (55 - Fig. C) according to the
indications of Table 1, using a gauge or equivalent instrument to set the distance “L”, and tighten the screw
provided to fasten the nozzle.
Turn the main switch (1) to position 1, so as to connect a single heating element (50% of the boiler’s electric
power for single-phase heating element with 2 elements and 1/3 of power for heating elements with 3 ele-
ments with three-phase connection), and ignite the burner as in the procedure described above. When the
water contained in the boiler reaches the preset temperature, the gas flow regulator will automatically decre-
ase the flow to the value corresponding to the reduced rated heat flow.
At this point, turn the flow regulation screw (58) so as to have a steady flame licking the sensitive thermocou-
ple element (52), and turn the screw (57) to obtain the maximum desired pressure value in the boiler.
After having verified the proper operation, replace the settings tag on the appliance with the one for the new
type of gas that is provided with the standard kit containing the newly installed gas nozzle.
Safety devices on appliance (manually reset).
The appliance is provided with two safety devices that shut off the gas flow if the flame accidentally goes out.
1 - Termocouple (52): The thermocouple operates on the valve (51), whose probe (52) must be licked by
the flame from the burner (50). If the probe is not enveloped by the flame, the gas flow will be automa-
tically shut off.
2 - Thermostat (59): The thermostat, placed in contact with the boiler, operates on the valve (51); when the
thermostat sensor on the boiler reads 140˚C, the gas flow will be automatically shut off.
The burner can be re-ignited with the procedure described above only after the boiler body has cooled to
110˚C. Following the activation of one of the two safety devices, try re-igniting the burner with the procedure
already described.
