6.5 Water renewal
When the machine is being installed, the Technician must re-
place the water inside the hydraulic circuits by following these
steps:
• When the installation is complete, the appliance must be
started, brought to the nominal working condition and
left in the “ready-to-operate” status for 30 minutes.
• Next, the appliance has to be turned off and fully emptied
oftherstwaterintroducedintotheentirehydrauliccir-
cuit, in order to eliminate any initial impurities.
• Theappliancemust thenbelled againwithwaterand
brought to nominal working conditions.
• Upon reaching the “ready-to-operate" status, the follow-
ing dispensing operations must be performed:
- Continually dispense from each coffee group, in order
to empty at least 0.5 litres from the coffee circuit. If
there are several dispensing points attached to the
same exchanger/coffee heating unit, divide the vol-
ume by the number of dispensing points.
- Empty the heating unit of all its hot water by contin-
uouslydispensingthroughthespecicnozzle.Ifthere
are multiple dispensing points, divide the volume by
the number of dispensing points.
- Continuously release steam for at least 1 minute from
each steam dispensing point.
If the machine remains inactive for longer than a
week, the Technician must renew 100% of the wa-
ter inside the hydraulic circuits, as indicated above.
Before using the machine, run a few empty dis-
pensing cycles with the lter holder attached for a
few seconds to release any air inside the circuit
and in turn, allow the dispensing groups to fully heat up.
Before using the machine, dispense a few coffees
to test the grind neness and to check the operat-
ing pressure of the machine.
6.6 Dispensing coffee
6.6.1 Preparing the lter holder
Before lling the lter holder, make sure it is
empty and any previous coffee residue has been
removed.
• Fillthelterwithadoseofgroundcoffee(approx.6-7g);
follow the procedures specied by the manufacturer of
the grinder-dispenser.
• Compress the coffee with the special press.
• Cleantherimofthegroundcoffeelterbeforeattaching
thelterholdertothedispensinggroup.
• Hookthelterholdertothegroupwithoutclosingittoo
tightly in order to prevent the gasket from wearing quickly.
6.6.2 AL version
Never perform the described operations without
coffee in the lter or without the lter holder at-
tached to the dispensing group. The rapid upward
movement of the lever may cause damage to the appliance,
individuals or property. The dispensing time depends on the
grind neness and the amount of coffee in the lter holder.
• Place the coffee cup under the
dispensing spout.
• Pull the lever all the way down.
• Wait a short time for the cof-
fee to be pre-infused (3-5 sec-
onds).
• Lift the lever until a certain re-
sistance is felt, then release it.
• Wait until the coffee has been
dispensed.
