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.

- Position 1: power supply to the operational electric components and to the heating element.

5. Technical description Crema Compact and Digital

Do not tamper with the machine´s components or pull on the electric power cord to unplug it.
Never clean the inside of the machine with the power ON or with the plug connected and do not use

detergents or jets of water in any case.

The operator must not touch the machine with damp or wet hands or feet, or use it with bare feet.

Allthough the machine is earthed, we recommend the use of a wooden foot-board and a centralized life­saving system to prevent the risk of electric schocks as much as possible.
Grinder shall only be used for coffee beans. All other usage could be dangerous and must seems like a
wrong and defective way to handle the machine.

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. (Cont aining the filter and the ground cof fee 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 dif ferent
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.
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 st arting 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 10.
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. Af ter 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.

The following should be considered general lines of operating. It is quite essential to follow the
manufacturer’s instructions and regulations as regards safety .

Operating the machine is very simple.
The checks that the operator obtains good coffee are:

- use suitably softened fresh mains water

- boiler water temperature between 85 °C and 105°C

- delivery time 20-30 seconds

- ground coffee dose between 6 or 7 g.

- constant cleaning of the coffee dosing grinder

- checking the wear of the dosing grinder’s grindstones

8.1 Normal operating values

Recommended values:

- Pump pressure: 8,5 - 9 bars

Pump pressure are factory adjusted. On Digital-model: Reading/Check the pressure on the manometer.
To Read/Check the pressure on Compact-model use a special equipment:(filterholder with manometer).

- Boiler pressure: 0,8 - 1,2 bars.
Pressure is the red color field on manometer. To regulate the pressure: (turn clockwise to increase
pressure and anticlockwise to decrease the pressure).

- Safety valve opening pressure: ± 1.7 bars

- Expansion valve opening pressure: ± 10.5 bars

Adjust opening pressure with a filterholder (sealed) and a manometer. When indicator shows 10,5 bar
it will start driping from the expansions valve.

- Coffee delivery temperature: 85°C - 92°C
The temperature depends on the type of blend used; it can be checked with a precision thermometer
during delivery .
The pressure switch ’s screw can be used for minor adjustments (see boiler pressure).
Allways adjust pressure when you are brewing coffee.

8.3 How to make cappuccino

For making cappuccino, fresh milk must be ”frothed” to give a foam which will be poured over the
espresso coffee. A cappuccino consist of 1 third espresso and 2 thirds frothed milk.

Brewing an espresso in a cappuccino cup.

Open steam tap position the steam pipe and switch the steam on for 1 or 2 seconds to clean away milk
residues.
For heating milk, use a jug containing at least three inches of milk.

Approach the jug to the stam pipe so as to immerse the spout in the milk.Slowly open the steam tap and
hollow the jug so that the nozzle is placed exactly at surface. Keep the jug in this position, until you can feel
a heat outside the jug.
Rise the jug a couple of centimetre and angle the jug until you get a wave motion in the milk.

With this procedure you can blow a ”vanilla sauce similar” milk-froth. It is that kind of froth they use in Italy
and with some practice you can draw and design shapes in your cappuccino and caffé latte.

Then quickly close the steam. Remove the jug from the pipe and pour the frothed milk over the espresso
coffee.

N.B. Heat up the milk to 60°C - 65°C
N.B.: the steam pipe is very hot and should not be touched until it has cooled.

Clean the milk from the pipe as soon as possible to prevent it from drying and becoming difficult to
remove.
Inform the customer as soon as possible that the drink is very hot. Keep extra frothed milk for the next
cappuccino.

8.2 How to make espresso coffee

Remove the filterholder from the group and dispose of the grounds by hitting the edge of the filterholder
against the bar in the apposite drawer. Do not hit the filterholder against an unprotected surface; the
filterholder’s seal could be demaged.
A smart blow should be enough. The small quantity of powder remaining will not have a negative effect on
the taste of the coffee.

Fill the filterholder with finely ground coffee. When the filterholder is filled, press down the ground coffee
with the special tamp, pushing the filterholder upwards. Clean the edge of the filterholder with the palm of
the hand to get rid of excess coffee powder.

This will ensure that the seal between the filterholder and the machine will be perfect.
If a filter for mixed use is being utilized, you can put a coffee pod instead of ground coffee in it. Hook the
filterholder in a careful way into the group. When it can be difficult to unhook filterholder after brewing.

After having fitted the filter holder properly , put a previously heated cup under the spout. Two cups are
required if a double filter holder is used. Press on choosed dose-button. Start brewing immediately. The
coffee deteriorates already after 10 seconds in the hot group.

When delivery is finished, remove the cup and serve it.

15.

9.1 Daily cleaning

Preferably done in the evening:

- CLEAN nozzles, gasket, filterholder and the bayonets in groups.
Use a clean dishing brush or the angled cleaning brush.

- RINSE 1 cup filter / 2 cup filter and filterholders with hot water. Use detergent intended for coffee
machines or dishing machines to remove oil and dirt

- Put the rubber pad in 2 cup filter. Hook filterholder in the group and st art a brewing.
V arying unhook and hook filterholder when brewing is going on.
The hot water will be pressed out between groups and filterholder and cleaning the bayonets in group and
filterholder gasket.

N.B.: the steam pipe is very hot and should not be touched until it has cooled.

- CLEAN Drip tray (placing the cups)..

- CLEAN Steam pipes directly after they have been in use.

9.2 Weekly cleaning

- CLEAN Group and nozzles:
See chap. 7.7

- Clean the tray and the cup support grid.

Carefully clean the steam pipes used for heating beverages immediately after use, so as to avoid
the formation of deposits which could block the delivery nozzles and also to prevent different types
of beverage being heated.

- Cleaning Machine: outwardly

Use a wet cloth (which not scratcing).
You must not use solvent or alcohol!

Identifying problems:

- Always ensure that there is enough ground coffee for at least one dose in the grinder-doser´s reservoir.

- If the coffee drops are to slowly then grinding is propably too fine. Vice-versa, if it drops to fast, the grinding is too coarse.

- Remember that the machine´s operating process forces the water over the coffee at high pressure. If contact between the
water and the ground coffee lasts more than 30 seconds, the coffee will taste unpleasent and bitter. The effect is called
over-extraction.

- Always heat the cup by rinsing it in hot water. If the cup is cold, the abrupt temperature change of the espresso coffee will
change its taste.

- Never load the filter holder without making an immediate delivery; the ground coffee would ”burn” in the group and the
espresso obtained would be very bitter.

Attention: ALWAYS UNPLUG THE ELECTRICITY when carrying out maintenance checks or operations.

The following maintenance operations must be carried out by specialized personnel, authorized by
