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.

7.1 Connection to gas supply
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.
