Steam dispensing
Plunge the steam jet pipe (6) into the liquid to be heated in a suitable container and turn the steam adjustment knob (7). When the liquid is hot, stop the flow of steam by turning knob (7) the other way (towards "0").
Cleaning of steam dispensing pipes
At the conclusion of each steam dispensing phase:
- Using a clean sponge, wash with hot water removing any organic residue present. Rinse carefully.
- clean the inside of the steam nozzle as follows:
Turn the nozzle towards the cup tray and carefully activate steam dispensing at least once.
Scalding hazard! Use the appropriate insulating devices to move the water and steam wands.
Dispensing with the Turbosteam selector (7a) (when provided)
Machines equipped with the TURBOSTEAM (STOP STEAM) dispensing system have the "stop steam dispensing when set temperature is reached" function, and can rapidly heat and froth milk.
Select the type of milk you desire:
using the knob (7a), clockwise (frothed) or counterclockwise (hot).
When the set temperature is reached, steam dispensing can be stopped:
automatically;
- manually, turning the knob (7a) in in any direction.
Temperature setting
The temperature setting for the "Stop Steam" function is factory set at 72^ (161^) and is therefore not set by the user.
Nevertheless, the standard setting can be changed within the range of 45 and 85^ (113÷ 185^)
To make this change:
- switch off the machine;
- remove the right side
- adjust the setting (R) on the Turbosteam card, keeping in mind the corresponding number of notches and temperature:
$$ \text {n o t c h} 0 = \sim 4 5 ^ {\circ} \mathrm {C} (1 1 3 ^ {\circ} \mathrm {F}) $$
$$ \text {n o t c h} 1 0 = \sim 8 5 ^ {\circ} \mathrm {C} (1 8 5 ^ {\circ} \mathrm {F}) $$
increment between the 2 notches = 4^ (39.2°F)
The indication of intermediate temperatures is approximate; after each adjustment, please use a thermometer to determine the actual set temperature.
The ideal setting for milk frothing is set in the factory. If = additional adjustments must be made, turn the flow adjustment valve (A):
View of the right side of the machine
Note: even slight turns of the valve (A) can make a great difference in how the milk is frothed.
Correctalignmentofthesteamthermocouple is performed in the factory: for this reason, do not turn the adjusting screw (T).
- counterclockwise: more air > more frothy milk
- clockwise: less air > less frothy milk
