nical support. In case of damage to the power
supply cord, turn off the machine immediately,
close the water and contact the technical assis-
tance service. Avoid replacing it autonomously.
Perform cleaning/maintenance with the machine
cold, preferably wearing protective gloves.
3.2 – Cleaning the machine
Warnings: For the best results and in
compliance with current regulations,
change the water in the boiler and pipes
when starting the machine every day.
This advice is for indication purposes only: main-
tenance and cleaning schedules depend on the
use of the machine.
After each use
1) Clean the steam wand.
2) Clean the filter-holder and filters.
Daily
1) Clean the cup rack and drip tray.
2) Clean the bodywork.
3) Clean the group gasket with the brush sup-
plied.
4) Wash the group as follows: clip the filter hold-
er with the blind filter supplied to the group
and start a delivery several times.
5) Immerse the filter-holders and filters in boiling
water for a few minutes to any coffee oils and
use a cloth or sponge to remove it.
For washing and cleaning, do not use
solvents, detergents or abrasive spong-
es. Only use specific products for cof-
fee machines.
Wash the bodywork using a cloth soaked in water
and/or neutral detergent, taking care to dry the
surface well before reconnecting the machine to
the mains electricity. Use water to wash the cup
rack and the drip tray.
To wash the tank after having extracted it, use wa-
ter and neutral detergents and perform thorough
rinsing. Reinsert the tank and reinsert the silicone
tubes, ensuring that the suction tube reaches the
bottom.
3.3 Safety thermostat – Manual
resetting
Caution! The operation de-
scribed below must be only
performed by an installation
technician authorised by the
manufacturer.
MOD.
During machine operation the overheating of the
resistance in the boiler can trig, disconnecting the
power, the safety thermostat that prevents the oc-
currence of more damages to the boiler. To re-
store normal operation, it is necessary to solve the
fault that has caused the intervention of the safety
thermostat and then restore the normal condition
by pressing the red button (RESET) (Fig. 12).
3.4 Cleaning hydraulic circuits after
a long period of inactivity
Once the hydraulic/electrical installation has
been completed, carry out a complete rinsing cy-
cle following the operations described in points
A and/or B.
Warnings: for use of the machine controls (valves,
dispensing group, switches, etc.) refer to the rela-
tive sections contained in this manual.
The introduction into the tank of chemicals, des-
caling agents, vinegar and/or even citric acid,
even if diluted, compromises the life of the ma-
chine components. Any product used that is not
fresh water will automatically void any warranty.
Use ideal hardness drinking water, in French de-
grees approximately 15°F; never use hot water.
A - Upon initial ignition or after a prolonged pe-
riod of inactivity of the machine (approximately
7 days)
1) Switch on the machine, fill the boiler with water
and heat as described in paragraph 5.
2) Wait 12 hours.
3) Perform dispensing for at least 30 seconds with
the filter-holder connected but without coffee to
allow the exchange of water in the exchanger (le-
ver machines need coffee inside the filter-holder).
4) Switch off the machine and completely drain
the water from the boiler by operating the water
and steam tap into a heat-resistant container with
a capacity of at least 1 litre.
Ensure that:
- there is always fresh water in the tank (where
required).
- do not re-use the water drained during rinsing.
B - After a stop of at least 4 hours
1) Dispense water from the respective tap for 5 seconds.
2) Perform dispensing with the filter-holder connected
but without coffee for at least 15 seconds.
