3 - Characteristics of the machine
The machines of the BIG DREAM T series have been designed to prepare espresso and hot
drinks.
The operating principle consists of a volumetric pump inside the machine that feeds the
hot water and steam boiler, in addition to the independent coffee groups. By activating the
controls, the water is sent to the external brewing units in the form of hot water or steam
according to the needs.
The water to be used to prepare the drinks is taken at the moment of the water network,
pressurized by the pump, passing through a pre-heating circuit through the hot water / steam
boiler, and its temperature is finally raised from the temperature from pre-heating to working
by a heat exchanger.
Each one of the spreader groups, as well as the hot water / steam boiler, can present a
different working temperature, as well as different independent configuration parameters to
optimize the machine's performance before the needs of the user.
The machine is formed by a supporting structure in stainless steel to which the mechanical
and electrical components are fixed. Everything is covered with panels of total coverage
made in Baydur© (polymeric material with high isolation features) and stainless steel. The
productive operations are carried out on the front of the machine and the controls, where the
control devices and the coffee brewing groups are located. In the upper part of the machine
there is a surface destined to heat the cups.

exhibition purpose. Please check section 12 for more information.
POWER/CURRENT TABLE
First, we will connect the free end of the drain pipe supplied with the machine to the
previously installed general drain outlet.
In connection with the general network, a tap must be incorporated to interrupt the
flow of water to the appliance when necessary. Next, we will connect the flexible hose
(connection 3/8 “H) to the pump and to the water inlet of the network. In case a water
treatment system is installed, we will connect the hose to the outlet of said system.
Attention! Recommended water parameters:

Free chlorine 0-0.05 ppm Network pressure 0.1-0.6 MPa
Total chlorine 0-0.1 ppm Flow rate 8 l/min

13
ENGLISH
If these parameters are not met in mains water, a specific filtration device must be
installed, always complying with current national and local regulations regarding
drinking water.
Once the water inlet and drain connections have been made, we will open the valve or
tap to fill the boiler.
ATTENTION!
This equipment is to be installed with adequate backflow protection to comply
with applicable federal, state or local codes.
Set the main switch to the "ON" position and automatically the machine will proceed to
fill the boiler to the set level. Once the filling process has been completed, the water will
be heated up to the working temperature and pressure.
Pump pressure regulation:
The pump is factory-set to 9 bar
pressure. If it is necessary to
adjust it, please turn the pump
regulator placed under the
machine. Turning it clockwise will
increase pressure, and counter
clockwise will decrease it. Please
check pressure while adjusting on
manometer.
From this moment, it will be necessary to wait until the temperature of the coffee
groups reaches the set-point (showed in the specific display of each group dedicated
to the temperature and also in the main display) in order to start making coffee, and
until the temperature of the steam/hot water boiler (showed in the main display)
reaches the set-pint one (the pressure gauge will show a pressure between 1 and 1.5
bar depending on the set-point) in order to start using the hot water or steam function.
7 – Start-up
ATTENTION: During the heating up of the groups, the 5 keys of each control
panel will alternate to be ON and OFF until group reaches set temperature. Then
5 keys will change to permanent ON position.

14
ENGLISH
You can use any type of coffee. For optimal results, we recommend using mixtures
prepared for the preparation of espresso coffee since the grinding point will be
adequate. If the coffee comes out very quickly or very slowly, it will be necessary to
change the type of coffee for another fine or coarser grind and experiment with the
pressing according to our preferences.
The steps to follow are:
1. You must have the machine connected. Place the filter holder (with filter) in the
group.
2. The 5 keys of the keypad must be permanently illuminated, which indicates that
the coffee machine has reached the ideal temperature to make coffee.
3. Press the XL key (continuous coffee output) of the keypad and let water through
the group. Perform this action before making coffee, eliminate waste and balance
the temperature for optimal service.
4. The pan must be filled 3/4 of its capacity, once pressed.
5. Clean coffee residues that have been deposited on the edges of the clay so that
the adjustment is perfect.
6. Insert the filter holder in the group starting from your left and turning to the right
with enough final pressure.
Place the cups or cup on the rack and press the keypad in the desired selection. The
perfect extraction of an espresso requires 20/25 seconds.
8 – Coffee preparation

15
ENGLISH
ATTENTION!
To obtain an optimum coffee extraction quality, always use the appropriate filter
for 1 or 2 coffees.
ATTENTION!
If the coffee comes out very fast or very slowly, it will be necessary to change the
grind of the finest or thickest coffee and experiment with the pressing according
to our preferences.
GENERAL ADVICE
1. The filter holder must always be placed on the machine to keep it warm. In closed
position.
2. Place the cups on the cup-warmer. The temperature (optimum 40ºC / 105ºF) will
improve our espresso.
3. The coffee will continue to come out in small drops a few seconds after turning off
the coffee breaker.
4. It is advisable to grind the amount of coffee needed at the time it is needed
because the ground coffee quickly loses its aroma qualities and the fatty
substances contained in the coffee become rancid.

16
ENGLISH
To program the amount of coffee (volumetric dose) or hot water (set by time, not
volume), with the machine ON and ready to make coffee (keys of the keypad
permanently lit), press the programming button XL for 5 or 6 seconds until it is lit
intermittently while the rest of the keys are illuminated in a fixed manner.
Then press the key of the selection you want to program, which is lit intermittently at the
same time that the other four keys are off. The erogation process begins.
Once the desired quantity has been obtained, press again the key belonging to the
selection you are programming. The dispensing process is stopped, and the key light
is OFF. Press XL button until all keys are ON except for this one, and then press it
twice until machines gets back to working mode. You can also wait for 30 seconds so
machine gets back to working mode automatically.
If you want to get coffee at will (continuous), press the XL key. When you get the
desired amount, press again to interrupt the delivery.

ADVICE. You can also adjust the dose through the main display, introducing the
volume you want for each selection directly on the display (ml). The sequence to get to
dose adjustment setting is as follows:
The true “cappuccino” is composed of 25 milliliters of espresso coffee and 125
milliliters of cold milk mounted with steam, which will go from 3 or 4 degrees Celsius to
about 55 degrees Celsius. The milk must be bovine and fresh with a protein content of
3.2 percent and 3.5 percent fat, and assembled - just the amount needed for a cup - in
a steel container (jar) to avoid mixing with other scents or flavors.
The density of the cream has to be uniform without there being a separation with the
liquid, nor can it present holes or bubbles.
PREPARATION
• Please check in the display that steam boiler reaches correct working temperature,
and that the steam pressure gauge shows a pressure between 1. 2 / 1.5 bar.
When switching ON for the first time, the boiler will be ready to dispense water and
steam in approximately 20 min.
• Turn the steam lever. It is normal that at the beginning of the steam service a little
water comes out of the pipe, so we recommend that you position the pipe in the
drain pan.
• Insert the tube into the milk to be heated. Fill up to 1/3 of the jar.
ADVICE. You can modify the temperature of the steam boiler through the main display.
Maximum allowed temperature is 130ºC. The sequence to get to the boiler temperature
setting is as follows:
1) TEXTURE: Getting cream
To obtain the consistency called “velvet”, the cappuccinator
tube should be placed just below the surface of the milk.
Open the steam control and move the tube at different
angles (always under the surface of the milk) to achieve
10 – Preparation of the cappuccino

18
ENGLISH
an emulsion effect thanks to air circulation. Once textured, the volume of milk can be
doubled.
Please remember to move the jug and steam tube, always making sure it works in the
most superficial area of the milk. After this operation, the milk is textured but is still cold.
2) TEMPERATURE: Heating the milk
Once the texture is obtained, we submerge the steam tube
(10) in the jug deeper. We make circular movements to
heat the milk in all its volume until it reaches the desired
temperature.
ATTENTION! Texture requires working under the surface of
the milk and heating requires working deeper
Texture Heating
Remember not to heat the milk to more than 75ºC. From this temperature the milk will
be blanched and lose its properties for the cappuccino.
Once the operation is finished, turn the knob (9) to close the steam outlet.
ADVICE. The espresso is extracted at 75ºC-80ºC. The milk is textured and hot
between 55ºC-70ºC. It is important to keep these temperatures when serving, so the
cups must be heated using the cup-warmer zone of the coffee maker. If this is not
possible, warm the cup with hot water before using it.
Once we have the hot and textured milk, we are ready to serve it in the cup, adding it to
our espresso base.
POSSIBLE PROBLEMS
The cream can be excessively thin and without consistency.
1) One of the reasons may be that the milk had already warmed up in advance.
2) The milk has been heated too much (the steam tube is placed deeper in the jar
and the milk is heated without letting the air circulate on the surface) before having
achieved the desirable texture. We have not done step 1 correctly: TEXTURAR and we
have not let the air work the milk.

19
ENGLISH
Attention! If you have used the steam or water service for a long period without
interruption and observe that the output pressure drops, wait a few moments for the
boiler to recover. The optimum pressure is 1 / 1,5 bar.
IMPORTANT!
After each use it is advisable to let steam out for 5 seconds to clean
the duct and prevent it from becoming clogged. To clean the absorption
holes (A) you can use a clip. Make sure that the tube is free of obstacles.
Put a cup or container under the water outlet. Operate the hot water switch (8, short or
large selection) to obtain water.
Both selections are set by time and will stop automatically after reaching the setting. If
you want to modify it, please follow section 9.

dust contained in the blind filter, cleaning the ducts and the solenoid valve, as
well as the showers and diffusers of the group. You can repeat this process as
many times as necessary and until clean water appears through the discharge
of the group.
Once finished, remove the filter holder and operate the group for 30 seconds,
passing clean water.
ATTENTION!
It is possible to stop the process pressing any of the keys of the control panel
belonging to the coffee group being cleaned.
