VARIABLE-DOSE COFFEE DOSER
A coffee-based selection can be composed
of two quantities of ground coffee: volumet
-
ric and timed; they are released consecu-
tively from the doser.
The dispenser releases the dose of ground
coffee when:
-The doser chamber is full (volumetric
release).
-When the time which has been set as a
percentage is reached, i.e. the volumetric
quantity of the grinding time.
If the percentage is set to 0, only one volu-
metric release is carried out;
If the percentage is set to 100, two vol-
ume-dosed releases are carried out (the
chamber will also be filled during the sec-
ond release).
The chamber volume of the variable-dose
doser can be adjusted between 5.5 and 8.5
g using the adjustment lever.
The dose adjustment lever can be posi-
tioned on one of the 10 reference marks,
whilst taking into consideration that:
-Raising the lever increases the dose:
-Lowering the lever decreases the dose:
-Each notch changes the dose by approx.
0.35 g.
Two different doses are managed in each
doser: the volumetric dose (for single cof-
fees) and the timed dose (for double cof-
fees).
The coffee unit can accept coffee doses of
up to 13.5 g.
-If a completely volumetric dose is opted
for (100% time - two releases), the 7 gram
adjustment for the doser volume must not
be exceeded.
In this case, the dose for single coffee will
be composed of 7 g (volume) plus the
grams ground in the programmed time
(volume grinding other than 100%).
-If you opt for the fully volumetric low dose,
the volume will need to be adjusted to the
desired dose with the addition of 0% time-
ground grams.
In this case, the dose for double coffee will
be composed of the volume-dosed grams
plus the grams ground in the programmed
time (volume grinding other than 0%).
Warning!
If the position of the adjustment
lever is changed, the percentage value of
the added dose will have to be reset.
Ensure the total dose does not exceed
13.5 grams.
