INFUSION FILTER
Do not remove the portafilter when group is actu-
ally brewing water.
• Rinse the group using a normal filter
in the portafilter, by running hot water
through it several times.
Cleaning filters and filter holders
For the daily cleaning of the stainless
steel filters and portafilters it is sufficient
to use water and a cloth or appropriate
brush. Otherwise, use an espresso clean
-
ing product according to the product’s
instructions, put a correct dose of the
same in about 1/2 a litre of water inside a
heat-resistant container and heat.
• When using stainless steel portafilters
with snap-on spouts remove those spouts.
Immerge filters and portafilter metal
-
lic parts (not handles) in a hot solution
and leave them submerged for about 30
minutes.
• Rinse thoroughly with clean water and
run hot water through the group sev
-
eral times with the filter and portafilter
engaged.
• Make one cup of coffee in order to
remove any unpleasant flavour.
Cleaning the drain collector
Remove the drain tray grill every night,
pull out the water drain collector and
clean it thoroughly.
Also, inspect and clean the drain well at
least twice a week and remove any leftover
grounds with a tablespoon.
Cleaning the body
Wipe the stainless steel surfaces with a
soft cloth in the direction of the glazing
marks, if any.
Do not use any alcohol or solvents whatso
-
ever on painted or imprinted parts in order
not to damage them.
Cleaning hot water and steam nozzles
Steam nozzles must be cleaned immedi
-
ately after use with a damp cloth and by
producing a short burst of steam (being
careful to avoid burns), so as to prevent
the formation of deposits inside the noz
-
zles themselves, which may alter the fla
-
vour of other drinks to be heated.
Cleaning diffuser screens (infusion filter)
Due to filter holder discharge operations
(subsequent to coffee brewing), a certain
amount of coffee grounds may slowly
build-up on and obstruct, even partially,
the infusion filter.
In order to clean, first remove them by
unscrewing the retainer screw, then soak
in espresso detergent powder.
Water Pump
Motor pump is a positive-displacement
one and can develop a pressure of 14 bar.
Its operating pressure is 8-9 bar and this
value is factory preset during testing; how
-
ever, such pressure may vary from place to
place since the pump pressure is affected
by incoming water mains pressure.
You must always check the pressure itself
by looking at the lower scale on the pres
-
sure gauge whenever you are brewing cof
-
fee, and you can increase such pressure, as
required, by turning by-pass screw (below
the plug located on the side to which the
pump power supply is connected) clock
-
wise, or reduce the pressure by turning said
screw counter-clockwise.
Adjust pressure only when at least one
group is brewing coffee.
