Coffee Delivery Unit Cleaning
CAUTION: RISK OF BURNS
OR SCALDING.
All cleaning operations must be carried out
using the small brush supplied. This ensures
that the operator does not come into contact
with heated parts.
- Set the machine to the “O” energy level;
- Open the control unit door;
- Remove any coffee residues deposited on
the delivery unit sides.
Regenerating the resins in the
water softener
( To be carried out by qualified staff )
To prevent scale forming in the boiler and in
the heat exchanger, the water sortener
must always be efficient. Regeneration of
the ionic resins must therefore be establi-
shed regularly and on precise dates.
Regeneration times depend on the amount
of coffee used each day and the hardness
of the water in the area.
As a guide, the times may be taken from the
diagram relating to the KD/8, KD/12 softener.
(fig. 10)
R e g e n e r a t i o n
Once the regeneration times have been
established, proceed as follows:
- Set the machine to the “0” energy level
(that is, machine switched off and the
plug removed from the mains) and place
a container with a capacity of at least 2
litres under pipe “E” (Fig. 11 / A )
- turn levers “C” and “D” to the right (Fig.
11/B).
- unscrew knob “G” and remove the plug.
- put in normal cooking salt (1 Kg for the
KD/8 model; 1.5 Kg for the KD/12).
- replace the plug and turn just lever “C” to the
left (Fig. 11/C) letting water drain out of pipe
“F” until it is no longer salty (about 1/2 hour).
- turn lever “D” to the left (Fig. 11 / D ) .
Installation and regulation of
the cappuccino maker
(fig. 12)
The MASTER/COFFEE model may be sup-
plied with an optional cappuccino maker for
the instant cappuccino; it can be inserted
directly on to the coffee outlet nozzle.
The following operations must be carried
out by a qualified technician.
I n s t a l l a t i o n :
- turn off the machine with the PLUG k e y
- open the front door;
- draw out and remove the standard steam
nozzle by loosening the screw fixing it to
the tap.
- mount the new steam fitting supplied in
the kit and tighten the screw after having
re-inserted the conical spring, being care-
ful not to damage the "O"-ring;
- connect the steam fitting to the cappuccino
maker (detail 2 point A) by the silicon tube;
- insert the other tube (for suction of the
milk) into the connection of part 5;
- fit the cappuccino maker into the space
made on the coffee output nozzle.
Setting:
- fit the cappuccino maker, keeping the ring
nut (4) fully screwed down on the nozzle
body (3);
- put the tube (8) inside the milk container
so that it can draw up the liquid;
- partially unscrew the ring nut (4) which
regulates the density of the froth in order
to obtain the density required;
- check that the boiler is at 0.8 bars pressu-
