- Repeat operation at 4 for the other doses
¾ Pr = Manual programming
Same proceeding as in calculated programming Pc.
- The manual programming doesn’t calculate the other doses (1, 2 or 3
cups), only the programed dose is modied.

steam dose
- You can stop before the end of the dose by pushing again the same key
Note: a safety cuts the ow after 105 seconds
¾ 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

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 dened, 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

Note: when a safety is switched on, the led blinks.
3. PROGRAMMING
The programming mode allows adjusting the steam and hot water time
together with the
SteamAir level temperature adjustment
¾ Hot water / steam delay time adjustment

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
