CHECKS AND SETTINGS
S
tandard calibration
the unit comes supplied with a selection dose table
which includes the calibrations and doses that are set as
standard.
To obtain the best results for each product used, we
recommend the following checks:
- The coffee pod shall be slightly compressed and moist.
- Infusion time
- The grammage of the coffee.
- The temperature of the beverage (about 70÷80° at the
nozzle);
- Dose of water.
The grammage of the product, the amount of water and
the temperatures are controlled Directly by the control
electronics.
The variation of these values is performed through the
following programming procedures.
coffee doSe
The maximum coee dose used by the infuser group is
13.5 grams.
Depending on the type of delivery (single/double) the
volume of the dispenser chamber must be adjusted.
By dierence, and depending on the desired dose the
percentage of the grinding time to be programmed for
the second quantity of coee should be determined.
W
ater doSe
The type of selection determines the amount of water to
be delivered in terms of volumetric meter pulses (cdv).
coffee grammage adjuStment
The dose adjustment lever can be positioned on one of
the 10 reference notches, 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.
For collecting the dose it will be sucient to remove the
coee unit and use the appropriate function of the "test"
menu in "technical" mode (see relevant paragraph).
Important!
The dose used is approximately between 7 and 13.5 g;
varying the degree of grinding, there are slight variations
in dose.
grinding Setting
Varying the distance between the grinders varies the de-
gree of grinding; the value of desired variation can be set
by 1/6 of a turn of the adjustment screw via the software.
The ner the grinding grade, the longer the beverage
dispensing time will be and vice versa.
Note: after varying the grinding grade, it is neces-
sary to carry out at least 2 selections for checking
the new ground coee granulometry.
milk calibration
Only models with cappuccino maker
doSe
The milk dose is adjustable (time) and programmable
from the menu.
temperature
The milk temperature is programmable by adjusting the
ow rate from the menu.
foam
The adjustment of the quantity of air (and thus of the
foam) that is deliv
ered together with the milk is adjusted
by the software.
A high percentage value involves greater amount of
foam.
eSpreSSo boiler thermoStatS
The temperature of the coee boiler is controlled by the
software and can be adjusted directly from the menu.
Please be aware that signicant temperature changes
aect the infusion time.
hot Water boiler temperature
The temperature of the coee boiler 7 instant beverages
is controlled by the software and can be adjusted directly
from the menu.
Steam boiler temperature
The temperature of the steam boiler is controlled by the
software and it can be adjusted directly from the menu.
