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.

Regeneration
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
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.
Installation:
- turn off the machine with the PLUG key
- 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-
