7.2 Coffee delivery
On pressing the corresponding key T1-
T2-T3 or T4, the corresponding delivery
solenoid valves are activated for the time
necessary to obtain the required amount
of product as previously programmed
(volumetric check).
The LED relative to the selected measure
remains on for the entire coffee delivery
time.
The delivery in progress may be
suspended before actually reaching the
desired programmed product quantity by
pressing any of the measure keys present
on the keyboard of the unit used for product
delivery.
It is also possible to obtain simultaneous
coffee delivery from all the machine units.
To proceed with a new programming
operation of other coffee measures T2-T3-
T4 (providing that the programming time
out time of 30 sec is not exceeded) simply
repeat the same operations with the same
sequence as undertaken for key T1.
Press key T5 to immediately escape from
the programming stage.
IMPORTANT: Should the PRE-
INFUSION function be active (see par.
7.5). Wait until the pre-infusion function
is complete before stopping delivery in
progress.
NOTE: During the programming of a unit
the function of the other units is deactivated
as well as tea dispensing.
To programme the other units, press the
specific programming key of each unit and
carry out the same operations as
undertaken on unit 1. In this case any
variations in the measures are activated
only on the unit on which one is actually
working.
