4.3 Electric + gas heating
• Proceed as indicated in paragraph 4.2 "Gas heating";
• after checking that the flame has ignited, turn the main switch (A)
to position 2. In this way the boiler heating element is powered
and operating pressure will be reached more quickly;
• wait for the operating pressure indicated on the pressure gauge
to reach the working value of 1-1.2 bar;
For reasons of safety, gas heating must be shut down
i
during long periods of disuse of the machine (during the
night or when the establishment is closed).
It is not advisable to put cloths or other objects on the
cup heater, as this obstructs normal air flow.

rinding and dosing coffee
Place the grinder-doser in a convenient place near the machine. Grinding and dosing of coffee must take place in
accordance with the instructions of the manufacturer of the grinder-doser. To achieve good quality espresso coffee we
suggest the following:
• do not keep large amounts of coffee in whole beans. Observe the expiry date indicated by the producer;
• grind the volume of coffee based on use, place the amount the doser contains and if possible use it before the end
of the day;
• if possible, never buy coffee that is already ground as it expires quickly. If necessary, by it in small vacuum-sealed
packages.
Fill the filter with a dose of ground coffee (circa 6-7 go.) and press it with the press. Attach the filter holder to the
dispensing group.
i
To prevent the seal wearing too soon clean the edge of the filter before engaging the filter holder on the
dispensing unit. Do not excessively tighten the filter holder to the dispensing group.
