TECHNICAL MANUAL
INTRODUCTION
The manufacturer reserves the right to make product improvements. It guarantees that this manual reflects the technological
state at the time the machine was sold.
We are open to suggestions from technicians on any way that might improve the product and the manual.
GENERAL WARNINGS
lOnce the packaging has been removed make certain the appliance is sound; if you have any doubts, check the fault
and contact the retailer or manufacturer directly.
lPackaging must not be left where children can reach it as it is a potential ha ard source.
lThe appliance must be installed in compliance with the safety standards in force in the country of use.
lThis appliance is completely safe only when it is connected to an effective earthing system that complies with the
safety standards. Make sure that the mains power is sufficient for the energy required for the machine.
lIt is unadvisable to use extension leads or electrical adaptors for multiple sockets. If it is essential to use them, use
only single adaptors or leads that comply with the current safety standards. Never exceed the capacity indicated on the
adaptor or leads, or the maximum power indicated on the adaptor.
lThis appliance should only be used for what it has been designed for. Any other use is considered improper and
consequently dangerous. The manufacturer cannot be held responsible for any damages caused due to an erroneous
or irrational use. The technician must remind the user about the safety standards to ensure correct operation of the
appliance.
lThe use of an electrical appliance must be subject to the safety standards.
lIf the customer decides he is not going to use the appliance for a long time, he must disconnect the power cable from
the mains and empty it the water contained therein.
lTo guarantee that the coffee-maker works properly and efficiently it is essential to follow the manufacturers instructions,
carrying out periodical maintenance and a check of all the safety devices.
lAlways make sure that hands, or other parts of the body, never come within the range of the coffee dispensing spouts
or those of steam and hot water since these can scald.
lThe repair technician must inform the retailer or manufacturer promptly of any problems when installing or using the
appliance.

4. PREPARING THE MACHINE
4.1 Unpacking
Proceed as follows to unpack the machine correctly:
1) Cut the straps around the packaging.
2) Pull the box off upwards.
3) Position the machine on the worktop.
4.3 Positioning the machine
There must be plenty of room for the appliance and for
using it correctly.
Prepare the place where the machine is to stand which
must be able to hold support its weight.
It is important that all the terminals of the connections to
the electricity mains and to the water mains are easy to reach
and in the immediate vicinity of the machine.
4.2 Preparing the grinder-dosers
Fit the coffee hoppers in place on the two grinder-dosers.
attention
For the machine to work properly it must stand on
a perfectly level surface.
Any corrections needed to level the machine can
be done by adjusting the feet.
We recommend keeping the packaging until the guarantee period
has expired.

5. INSTALLING a d MAINTENANCE
5.1 Hydraulic connection
The softener provided with the coffee-maker has been designed to function with a working pressure ranging between 1
and 9 bar. It must only be supplied with cold drinking water.
When connecting to the water mains, install a cock between the machine and the mains so as to be able to interrupt
the supply of water to the appliance.
To stop the water from free ing, install the softener in a room where the temperature is higher than 0°C.
Before connecting the pipes remove any rubber plugs from the softener cock couplings. To connect proceed as follows:
When plumbing the coffee maker do not use iron or
galvanised iron fittings because, with the passing of
time, these materials can produce dangerous
oxidations and seriously damage the machine.
attention
1) connect the water mains (1) to the softener inlet (2)
using the flexible pipe provided;
2) rinse the softener resins checking that the water, that
is initially yellow, becomes a clear colour;
3) connect the softener outlet (3) to the machine (4);
4) connect the machine drainage trough (5) to the drain
(6) using the specific pipe provided, taking care to avoid
sharp bends or throttlings and keeping it slanted
enough for the waste water to drain away;
5) the drain (6) must be connected to an inspectionable
trap (7) that can be cleaned regularly to prevent the
reflux of bad smells.
5.2 Maintenance and cleaning
To make it easier to service and clean the inside
of the machine you can remove the various parts of
the external casing.
From the front, in particular, you can access the
inside of the machine by opening the doors that cover
the unit and push button panel.
attention
To avoid damaging the outer casing, valves and cocks, install the softener where it is protected against accidental knocks.

5.4 S itching the machine on and adjusting the pump
Switch the machine on as explained in the user manual.
Effect several automatic washing cycles and check the correct working
pressure on the gauge (8 - 9 bar).
If necessary, calibrate pressure by means of the by-pass adjustment
screw (1) on the pump.
