Water system diagram
The water used for production of coffee does not come from the boiler. It is supplied directly from the water
net, through the heat exchangers inside the boiler. The hot water and steam surrounding the heat
exchangers, give the water inside the right temperature. This is shown in the water system diagram
Wiring diagram
The machine is connected to the power supply network by means of the electric cord supplied. See p. 35.
The main switch
The machine is fitted with a two-position power switch:
- Position 0: no power supply to the internal components.

5. Technical description Crema Compact och Digital
5.2 Operating Principles
An espresso coffee machine is basically made up of the following elements:
Boiler
Is used to contain the hot water and steam.. Made of copper to get a equal temperature over the year.
Brewing group and heat exchanger
The brewing group is the component which, when attached to the filterholder, brews and delivers the
beverages when supplied with hot water. (Containing the filter and the ground coffee or coffee pod).
The heat exchangers, one for each group, are immersed in the water and are used for fast heating of the
fresh water from the network to the optimal temperature and to prevent thermal imbalances within the system.
Heat source
This is normally provided by an electric heating element immersed in the boiler and/or by an external gas
burner , which heat the water and provide the steam.
Electric pump
This device is used to raise the pressure of the network, which is normally inadequate for the purpose, to a
pressure of 9 bars which is ideal for making the best coffee.
Steam taps
This allow steam to be delivered to give the indispensable ”froth” to the milk used for preparing cappuccino,
for heating water and punches and for preparing chocolate drinks.
Water tap
It allows water to be delivered for preparing hot drinks, tea and tisanes.
Control instruments
Manometers: show the current pressure in the boiler and in Dig. models the pump´s operating
pressure.
Pressure switchest: control the pressure and switching ON/OFF the heat sources to keep the boiler water
temperature constant.
Level gauge: shows the water level in the boiler.
7.1 Precautions for installation
The manufacturer has obviously taken every possible precaution to guarantee user safety, but the different
installation and/or transport conditions could give rise to uncontrollable or unpredictable conditions; so it is
always necessary to assess hidden hazards and to consider the following suggestions:
- The packing elements (cardboard, cellophane,metal staples, etc.) can cut, wound or cause
accidents if not handled
carefully or if used incorrectly; do not leave them accessible to children or unsuitable people.
- Any fault or defect should be promptly notified to the personnel who are qualified and authorized to
carry out installation and maintenance.
- An earthing connection is mandatory as is the system´s conformity with the regulations in force in
the country of installation. The manufacturer accepts no responsibility for accidents due to noncompliance with the regulations.
- The use of extensions or flying connections is prohibited. The working environment is heavily
exposed to water and damp which prevent the natural conditions for insulating the system.
- The machine must only be installed by authorized, qualified personnel.
- Check the condition of the components and, should defects or faults arise, stop the installation and ask
for their replacement.
- Ensure that the power supply voltage (see rating plate) is the same as that of the mains supply network
to be used in the place of installation.
- The customer must provide for the machine´s power supply, protecting the line with a suitable safety
cut-out (life-saver).
- It is important to place the machine on a flat surface! Adjust the machine feets and check with a
spirit level.

7.2 Locations and connections
Before installing the machine it is advisable to check the efficiency of the water mains (pos. 10 fig. 1), of the
electrical connections (pos. 1 fig. 1) and of the gas mains ( for gas heated machines). An electric cut out
(pos. 2 fig. 1) with fuses rated for the machine´s electrical input is needed for the machine to be properly
connected.
Attention: the earth connection (yellow/green wire) is mandatory.
Finally the efficiency of the main drain pipe must be checked before it is connected to the machine´s drain
pipe (pos. 7 fig. 1).
Hydraulic connections: - Water inlet: pipe3/8 union int D 10/12 mm.
- Drain: pipe int D 16/17 mm.
Locate the machine on the shelf and find a suitable position for the water softener (pos. 12 fig. 1).
- Connect the softener to the tap (pos. 9) using the pipe (pos. 11 fig 1).
- Connect the pipe (pos. 13) to the water inlet (pos. 12).
Connect pipe (pos. 7) to the drain tray (pos. 6) and then to the main drain pipe (pos. 8).
- Place a recipient under the water softener´s discharging pipe ( see regeneration instructions page 10 ).
- Open tap and run the water through for a few minutes to clean the softener.
The pump is equipped with a inlet filter which prevents unwanted particles from the system of water mains,
to damage the machine.
Check and clean the filter every month.
Make the electrical connections, connecting the power supply cord (pos. 3) to the mains line switch (pos. 2).
If the machine is fitted with a gas system, connect it to the pipe (pos. 16 fig. 1) using the tap (pos.17) and
adjust it as instructed.
7.3 Start up
- Make sure that the water tap to the machine is open and that the softener´s tap are turned to the
left!
- Turn ON main switch. The machine is fitted with water level control and boiler will be filled automatically
with water.. Machine is also equiped with a element defence and must not be filled up before starting up the
machine. Before starting machine, make sure that the water is on.
Filling of water stop automatically after 120 seconds. Turn OFF the machine with the main switch (pos.
4) and turn it ON again after 5 seconds. The filling of water will start again. Se chap. 7.6 page 9.
When the water in the boiler reach the right level, the machine stops filling water. Push ON the right button
for each group to fill up the heat exchangers. When the water is coming out from the groups in a even
stream, turn OFF with the same button.
The water will now heats up and the pressure in boiler accumulates to 1 bar. Meanwhile the water is heating
up, place the filter holders in there groups so that the filter holders leaves varm. After brewing allways leave
filterholders with coffee grounds in there groups. It is a better way to make coffee if filterholders are varm.
After a while you hear a ”ventilated sound” . This is normal. When the pressure are approx. 1 bar and the
groups and filterholders are varm. The machine is ready to use.
7.4 P semi-automatic version operation On-Off.
