Preparation
6.1 Preparation of the machine
The preparation of the machine and the instal-
lation operations must be carried out by qualifi ed
personnel only.
The installer must strictly follow the indications
provided in chap. 5 "Warnings for the Installer".
!
Using the machine without all the installation
operations having been carried out by technical
personnel could damage it seriously.
6.2 Grinding and dosing coff ee
Place the grinder-doser in a convenient place
near the machine.
Grinding and dosing of coff ee must take place
in accordance with the instructions of the manu-
facturer of the grinder-doser.
To obtain good quality espresso coff ee we sug-
gest the following:
•
not to store large amounts of coff ee beans. to
observe (in any case) the expiry date indicated
by the producer.
•
to grind an amount of coff ee based on use, pre-
pare the amount contained in the doser and if
possible use it before the end of the day;
•
never to buy (if possible) already ground coff ee,
as it expires quickly. if necessary, to buy it in small
vacuum-sealed packages.
to fill the filter with a dose of ground coffee
(about 6-7 gr.) and press it with the special coff ee
presser. Hook the portafi lter to the delivery group.
To prevent the seal from wearing too soon,
!
clean the edge of the fi lter before engaging
the portafi lter on the delivery group. Do not
excessively tighten the portafi lter to the dis-
pensing group.
