6.STARTING-UP
Filling the boilers
Turn on the shutoff valve.
Plug in the machine.
Set the charge switch to Position 1. (Do not set the charge switch to
Position 2 until the boiler has been filled).
ON/OFF SWITCH
Steam boiler
- As soon as the machine is turned on, the filling takes place automatically.
A safety is programmed, if the filling does not occur before 3 minutes. In this special case, the
electrovalve and the pump are cut off.
The light blinks.
- Check the hydraulic connection of the machine.
- Switch off and switch on the machine by setting the charge switch to Position 0 then to position 1.
- The filling starts again and lasts 3 minutes.
Internal boilers
- With the filter holder in place, press the continuous/stop key of each unit.
As soon as the water flows correctly from the spout (with no air), press the same key again to stop
the water.
Heating
When the boilers have been filled, set the charge switch to Position 2.
When the operating temperature of the machine is reached, the pressure-gauge must indicate a
pressure of 0.9 to 1 bar (red scale).
It is better to keep the machine switched on permanently and the filter-holders inserted in
machine even when you are not making coffees.

7.CHECKS AND ADJUSTMENTS
To get to the various adjustments, the cup rack, the rear panel or the sides must be removed.
Proceed as follows:
CUP RACK:
Remove the grids, then undo the 4 upper
screws. And remove the cups rack.
REAR PANEL(S):
Undo the 2 upper screws located inside the
machine at its back (under the cup rack); then
make the panel(s) glide vertically outwards.
SIDES:
On each side, undo 1 screw under the front
panel; pull the side to the back.
Temperature adjustment by means of the electric pressure
controller
The pressure controller (pressurestat) is located at the
back.
Dismantle the cup rack; remove the cover of the
pressure controller to get to its adjustment screw.
-TIGHTEN to LOWER the temperature
-LOOSEN to RAISE the temperature
The pressure-gauge (red scale) must
indicate a pressure of between 0.9
and 1 bar which corresponds to a
temperature of 120°C.
Pressure-release valve adjustment
MIRA Model
The HP valve is located on the right side of the machine: it
is necessary to dismantle the sides and the rear panel.
The valve is set above the pump; its adjusted pressure
must just be greater than the water network pressure.
Recommended value: 7 to 8 bar (green scale of the
pressure gauge).
- If the valve opens ABOVE 8 bar: LOOSEN
- If the valve opens BELOW 7 bar: TIGHTEN
Use a pin-wrench; after the adjustment, do not forget to
block the counter nut.

9
TWIN, TRI and QUATTRO MIRA Models
The HP valve is located in the lower part at the left rear of
the machine: it is necessary to dismantle the left side.
The valve must open at about 13 bar (green scale of the
pressure gauge).
- If the valve opens ABOVE 13 bar LOOSEN
- If the valve opens BELOW 13 bar TIGHTEN
Use a pin-wrench; after the adjustment, do not forget to
block the counter nut.
Pump-pressure adjustment
In infusion, the pressure must be between 9 and 10 bar (pressure gauge - green scale).
MIRA Model
The pump is located in the left side
and the adjustment must be done from
the same side of the machine.
TIGHTEN to INCREASE the pressure.
LOOSEN to DECREASE the pressure.
TWIN, TRI and QUATTRO MIRA Models
The pump is located in the right side
and the adjustment must be done from
the same side of the machine.
TIGHTEN to INCREASE the pressure.
LOOSEN to DECREASE the pressure.
Coffee grinding adjustment
- Wait until the machine has reached the proper temperature (0.9 to 1 bar).
- The fineness of the grinding determines the time it takes for hot water to pass through the
coffee.
- The passage-time is usually checked by using the 2-cup filter, with 2 doses of ground coffee.
- The average passage-time for 2 cups (6 to 7 cl. per cup) is from 30 to 35 seconds.
- If the passage-time is shorter, grind the coffee finer.
- If the passage-time is longer, grind the coffee coarser.
- For a good cup of coffee, use at least 6 gr. of ground coffee per cup.
8.PROGRAMING OF THE DIFFERENT COFFEE QUANTITIES IN
THE CUP

9.HOT WATER-STEAM BOX, STEAMAIR OPTION
Hot water – steam box
1: led
2: programming key
3: hot water small dose
4: hot water large dose
5: steam dose
Use
-An impulse on the keys 3 to 5 makes the corresponding dose flow:
Hot water keys 3 and 4 – Steam key 5.
The led lights in green during an hot water dose delivery, in red for a steam dose.
-You can stop before the end of the dose by pushing again the same key.
Note: a safety cuts the flow after 105 seconds.
Programming
The programming mode allows the delivery time adjusting for steam and hot water
-Keep the key PRO (2) pressed on until the led lights in orange.
-Place a container under the appropriate outlet and press the key (3 to 5) to set.
-When the level in the container is convenient press again on the same key.
-Press on PRO (2) to confirm the new adjustment and come out of the programming mode.
Note: the programming mode is automatically switched off after 20 seconds without any action.
SteamAir option
The SteamAir option allows, particularly when making cappuccino, to foam the milk very easily and
automatically: the supply of air mixed with steam brings milk to a programmed temperature (60° to
70°) and foams it.
The stop is done automatically when the temperature is reached which saves milk from boiling. By
this way the milk qualities are preserved.
Once the air/steam adjustment is defined, the operation is as follows:
- Insert the SteamAir outlet into the milk container
- Push on the SteamAir key
Wait for it to stop automatically.
The SteamAir box also controls a timed steam and hot water outlet.

Components
Outlet cleaning:
- Brake down the device and clean it once per day minimum.
- After each use, rinse the outlet using the Steam.
Use
Steam and hot water keys:
- An impulse on the key activates the corresponding flow delivery.
The led lights in green for an hot water dose and in red for a steam dose.
- To stop before the end of the delivery, press again the same key
Note: a safety stops the flow after 105 seconds for the water and after 180 seconds for the steam.
SteamAir key:
- Automatic mode: (To reach the programmed T°)
One impulse on the key makes the SteamAir flow until the liquid reaches the preset temperature
(see § programming)
You can stop it manually by pushing again on the key.
- Manual mode: (Over the programmed T°)
If after the stop in automatic mode (temperature reached) you wish to continue the heating, you
have to press again the key.
Then you go into manual mode and the outlet is again activated.
To stop you will have to push again on the same key.
If you don’t do it, it will be stopped automatically by one of the two safeties: after 180 seconds or
when the liquid temperature reaches 96°
Note: when a safety is switched on, the led blinks.

Programming
The programming mode allows adjusting the steam and hot water time together with the SteamAir
level temperature adjustment.
Hot water / steam delay time adjustment:
To adjust the hot water and steam delay time you have to:
- Switch off the machine by cutting the main switch.
- Keep the programming key (2) pressed on, when switching on until orange blink of the led which
confirms that you have entered the programming mode.
- Place a container under the appropriate outlet and press on the key to set (3 or 4).
- When the level in the container is convenient press again on the key.
- Press on the programming key (2) to confirm the new adjustment and come out of the
programming mode (the led blinks twice in orange).
SteamAir temperature adjustment:
To adjust the SteamAir temperature, you need (with power on) to:
- Maintain the key pressed on until orange blink of the led which confirms that you have entered
the programming mode.
- Press the SteamAir key paying attention to the number of blinks and colour of the led which
shows the temperature adjustment registered: the led lights in orange, it means that the adjustment
is as in factory 62°C.
A blink corresponds to a difference of 2°C compared to the factory value; with green colour it is
below, in red it is above.
Examples:
2 green blinks means that the temperature is set to 58°C (62° - 2x 2°)
3 red blinks means that the temperature is set to 68°C (62° + 3x 2°)
To modify the adjustment:
- Each impulse on hot water key (3) reduces the temperature of 2°, on the steam key (4) increases
of 2°.
- Press on the SteamAir key to check the adjustment: check the number of blinks looking the
colour of the led.
- Press on the programming key (2) to confirm the new adjustment and come out of the
programming mode (the led blinks twice in orange)
Note: The temperature adjustment can be done in a range of 50°C to 90°C.
