A coee-based selection can be composed
of two quantities of ground coee: volumet-
ric and timed; they are released consecu-
tively from the doser.
The dispenser releases the dose of ground
coee:
-The doser chamber is full (volumetric
release).
-When the time that 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 via the adjustment lever.
The dose adjustment lever can be posi-
tioned on one of the 10 reference notches,
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 dierent doses are managed in each
doser: the volumetric dose (for single cof-
fees) and the timed dose (for double cof-
fees).
The coee unit can accept coee doses of
up to 13.5 g.
-If you opt for a fully volumetric dose (100%
time - two releases), the 7 gram adjust-
ment for the doser volume must not be
exceeded.
In this case, the dose for a single cof-
fee will be 7 g (volume), plus the grams
ground in the programmed time (grinding
a volume 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 (grinding a volume other than 0%).
If the position of the adjustment lever
is changed, the percentage value of the
added dose must be recalibrated.
