It is important to not use hands or other nude parts of the body to get in touch with the hot metallic parts
of the machine, such as the brewing groups, the water spigot and the steam arms because the hot water
and the steam can be very hot and hurt and burn your skin.
The metallic part of the brewing groups, steam wands, and water spigots is very hot when the machine is
working at its normal regime, so please be very careful with that. Steam wands must be always handled
by its burn protectors and the filter-holders by its black handle.
Make sure the cups are totally dry when placing them on the cup-warmer grill (top of the machine). This
will avoid water from getting inside the machine and will allow you the have warm cups much faster.
Only silverware and ceramic cups which are specific for this kind of machines can be placed on the cupwarmer. In case you have doubts, please contact with the seller. Warming any other object is therefore
considered not appropriate and dangerous.

3.2.- Preparation and start-up
This Espressomat Serie-H Galaxy Coffee machine can be manufactured in 1, 2 or 3 group heads, and can
be equipped with Basic, Standard or High gamma accessories. This is a professional, trustworthy, high
performance and efficiency machine.
Before the technician turns on a machine, he must make sure that the socket has a proper ground and
that the water inlet pipe and drainage tube have been properly installed. Moreover, the water key must be open to
let water in when the machine starts running. The minimum Net pressure is 300 kPa (3 Bar).
Make sure all these preparations and parameters are correct. After this is done, the machine can be
plugged to power (1 Phase, 110V or 220/230V depending your case and 50/60Hz) and turned on by the technician.
We can also supply 380Volt, and 2 Phases.
When turning on the machine, place the main switch to Position 1. This will permit the machine to start.
First thing the machine will do is checking the water level inside the boiler. As it is empty, the machine will start
filling the boiler. The Pos. 2 in the main switch makes same function as Pos.1. Pos.2 will turn on and off the Led
If for any reason the boiler does not finish the filling process during 2 minutes, the buttons on the touchpads will blink. If this happens, place the main switch in Pos.0 and start the process again. In order to help the
machine filling the boiler, we can open the faucets/taps and press a button on a touchpad to activate the group.
This will release possible air accumulated inside the system. Just to know that the machine comes with a electronic
level control, so each time the machine detects a lack of water inside the boiler, it will automatically activate the
motor-pump and the filling solenoid to refill the boiler.
The machine has been equipped with a double probe system. One probe is to protect the heating element
(Security probe) and the other probe is to control the water level inside the boiler (Level probe). First probe will
allow the machine to heat the water when it arrives to that minimum level inside the boiler, and the second probe
will limit the filling of the boiler, avoiding the boiler from exceeding its water level. Otherwise there would be not
enough room for the steam.
Being the boiler filled, the element will keep heating the water during aprox 15 minutes until the steam
pressure inside the boiler is 100 kPa (1 Bar), and the temperature of the water reaches aprox the 100ºC (212ºF).
Now it will be only the pressure-stat the one to run the machine. It will control when the element must turn
on and off to heat the water inside the boiler and generate enough steam pressure. So now the machine is ready
to start making coffees and getting hot water for tee or steam to froth the milk, shakes, etc.
Once on a while make sure all the parameters are correct: water net pressure must be minimum 300 kPa
(3 Bar), boiler pressure 100 kPa (1 Bar) and pump pressure 900 kPa (9 Bar).
If some of these parameters are not correct, please let the technician know so he can adjust them again.
Never open the machine and try to adjust or modify these parameters for yourself!!!
3.3.- Preparation and coffee brewing
When all is ready to work, we recommend to play with the machine. It means taking some water from the
groups by pushing on a touchpad button (or the push-button if the machine is semi automatic), as well as getting
out some steam and hot water. This will warm the group heads and the wands and so the machine will be ready
to make coffees.
When pressing a button from a touch pad, the corresponding green/blue Led will blink showing that the
brewing process is working properly.
The touchpad has 4 programable buttons for coffee (from left to right: 1 short coffee/espresso, 1 long
coffee/americano, 2 short coffees/espressos, 2 long coffees/americano) and a fifth button for a Continuous
Brewing (button with a “C” or “Star” on it). In case of automatic water, use the 6th button for that purpose.
The Continuous Brewing button has 2 main functions:
1- It allows the user to make a continuous brewing of coffee.
2- It permits the user to enter into the programming mode to control the dosages of each button.
In the first case, the buttons permits a continuous coffee extraction, i.e. it starts when pressing the button
and only stops when pressing again. It is very important to read the following warning.
In case to use the “C” button (Continuous Brewing) to make coffee, make sure it does not keep activated too
long. In fact, 30 seconds are more than enough to make a long coffee (the so-called ‘americano’ coffee), so we
Strongly recommend to not use it more than 30 straight seconds.
In case we want to use the “C” button to make several long coffees (with a minimum of 30 seconds each), we
should not make more than 30 long coffees/hour, and then let the button rest a minimum of 2 - 5 minutes.
If the “C” button kept activated for a long period of time and with no control of the user, the machine would run out
of hot water in the group heads, would be disabled for some time to make coffee again and it would need some
time to get back into the proper functioning regime. In addition, letting the “C” button activated for long time would
cause severe damages to the machine.
These damages can always vary, but a lack of water coming from the net as a consequence of a wrong use of the
“C” button could overheat and damage the pump. And on the contrary, a never ending leak of water coming out
from the group heads with no control of the user could cause severe damages and losses to the local, either is a
possible flood or sparks as a result of possible contact between water and electricity.
So, just remember to use the “C” button under a strict control of the user.
Advice: It is always preferable to use the 4 provided programmable buttons to make coffee.
In the second case, the Continuous Brewing button permits the user to enter into the programming mode
to control the dosages of the 4 programmable buttons. To do this, we’ll need to press this button during 5 seconds
until the Led blinks. Now we’ll have 30 seconds to program the dosages. After 30 seconds the program exits the
menu, so we’ll need to enter again if we need to program additional buttons. The programming introduced in the
left touchpad will keep saved on the right touchpad buttons after we leave the programming mode.
In addition to the touchpads, this machine has 2 additional semiautomatic buttons for coffee
brewing. IMPORTANT: They should only be used in case the touchpad/s fail, and always try to have them in
Position “0” (zero, so deactivated) to avoid that when pressing any button on the touchpads, coffee will come
out from all the groups. To activate the semiautomatic buttons, put the white switch located behind the front
panel in Position “1”. After their use, put again the white switch in Position “0”.
Note: Read carefuly the instructions for the Display and its functions in next page.

2. Display en Mode OFF: We will use the Display OFF only to enter the Technical Programming
3. Alarms. These are signs the Display shows when problems or defaults occur.
Important Note: At this point, and before entering the menus to program the machine,
or change the name on the display, set the time, etc. .. we must ensure that the control unit is adapted
to work with our machine, since there are machines with pressure switch and machines without
Main boards are programmed at the factory with the option "Temperature" activated, that is to work
with machines that have a temperature probe. So, in case the machine has Pressure switch, we must
deactivate the "Temperature" option from the Technical Menu 2.5.13.
And in case the machine has temperature probe, you do not need to do anything.
1. Display in Mode “ON”
Having the machine turned ON and the Display in MODE ON, we can Dosage the coffee, and enter
the Dose Programming Menu, Clock, Auto On / Off, Coffee Counters, etc.
1.1. Coffee dosage: This option is elementary, and is that when we select a dose of coffee, we see it
indicated on the Display. And in case we have the timer activated, we will see the dosing time
indicated on the Display. The timer is activated / deactivated from the Technical Menu 2.5.3.
1.2. Preinfusion: Programmable from Technical Menu 2.5.10.

NOTE: If we need it, we can put the coffee counter to Zero proceeding in the following way: With the
ON display, we will press button 5 for 5 seconds until the Menu "Dose programming". Here we press
button 5 again to see CLOCK, and again to see COUNTERS. Now we will press button 3 to see
LITERS. And button 5 successively until the option "TOTAL COFFEES". Press buttons 3 and 4 at the
same time for 3 seconds and the value will be automatically reset.
2. Display in Mode “OFF”
Having the Display in OFF MODE we will enter the Technical Programming Menu.
Here we will see how to enter the Technical Menu of programming the general parameters of the
machine, and in turn we will see how to deactivate the option "Temperature" so that the control unit
works correctly in case the machine has Pressure switch (if it has a temperature probe this step should
not be done). NOTE: This should only be done by a qualified technician.
2.1. Press button 5 for 10 seconds in a row. The word LANGUAGE, IDIOMA, LINGUA, SPRACHE,
etc.will appear on the display. depending on the language that comes from the factory.
2.2. With button 1 we can go from language to language.

have to activate the Display again to have all the functions at our disposal. That is, it is only about
putting the Display in Mode ON (button 5 + button 3).
3. Alarms
3.1. Load Time Out: This alarm is displayed when the water load time in the boiler is exceeded. To
remove the alarm we must turn the machine off and on again. Check the water inlet of the network
or from the water purifier, as well as the load solenoid valve or the level probe, to verify that the
load is carried out normally.
3.2. Probe temperature: If the temperature is too high, this alarm will be displayed. The value given to
the temperature probe should be checked. To exit the alarm, we must turn the machine off and
3.3. Interrupted probe: This alarm usually occurs if the temperature probe has a detection problem. In
this case, the electrical connection of the probe must be checked.
3.4. Volumetric counter: This alarm usually occurs if one of the volumetric counters is not detected, or
is stuck, has lime, or is badly connected, etc. In this case, the meters must be checked.
3.5. Change Filter / Reset Filter, etc: Alarm for changing the softener if the warning option has been
previously selected in case of change of water softener.
3.4.- Hot water spigot
Before getting hot water into a cup or a pitcher, it is always convenient to open/activate the hot water
faucet/tap for a couple of seconds. This will keep the spigot warm and will avoid the temperature of the water going
down when touching the s/steel wand.
3.5.- Steam wand
It is also convenient to get some steam during a couple of seconds, to release any possible water
condensation inside the wand and keep it also warm.
3.6.- Cleaning procedures
When finishing the daily work with the machine, remove the filter-holders from the group heads and
immerse them into water. This will help you to clean them. Moreover, get some steam through the steam wands
and clean any possible rest of milk with a wet cloth.
In addition, get some water from the group heads to clean the shower and avoid coffee rest to get stuck
Then you can turn off the machine and open a steam faucet/tap to release steam from the boiler. Also the
service tray can now be removed and cleaned.
Finally, you can clean the front and sides of the machine using a wet cloth, and place the cleaned and dry
components in the right place. Like this, the machine will be ready to start next day.
3.7.- Water softener (not included)
Ask your technician about water softeners. It is always convenient to use a water softener to prevent future
problems. Scale/lime is always the worst enemy of the machines.
The softener extracts the scale from inlet water, avoiding the creation of lime deposits and encrustations,
i.e. many problems in the future. There is different types of softeners:
In case to use a salt softener, make sure you fill it with salt at due time or ask your technician to do so.
The regeneration is the process through which the softener comes back to its original state by the addition of salt.
The presence of salt inside the boiler and pipes as a consequence of the non regeneration nullify any granting of
warranty from the factory. (The softener is not included with the machine).
In case to use a cartridge softener, make sure you have the proper replacement ready when it needs to
be changed.
3.8.- Alarm signs
The machines are equipped with an alarm. It gets activated if one of the following situations occurs:
1- It takes too long to brew the coffee (possible causes: coffee too fine, too much pressure, etc).
2- It takes more than 2 minutes to fill the boiler.
When this happens, the touch pads blink and in case the boiler is filling, the filling process also stops…
4.1.- Description of the internal components
Our qualified technicians know very well the machines and how they work. However, we have
prepared an in-person-course for all those that want to extend they knowledge about the machines, their
components, how to service, maintain and repair them in place, etc.
4.2.- Positioning of the machine
The machine must be placed in a place that permits the user to work comfortable, and which is dry
and flat. It is convenient that the surface inclination does not exceed the 2º. A bigger inclination could
cause imbalances on the machine, like different quantities of water coming out from the groups, etc.
4.3.- Connection to water net
As mentioned in paragraph 3.2- , the technician must install the water inlet pipe (metallic flexible
pipe) and the drainage tube (grey flexible tube) before the machine is turned on.
Moreover, it is important to verify that the water key is opened and the water pressure has a
minimum of 300 kPa (3 Bar), so that the machine works in a proper and comfortable way.
4.4.- Connection to electrical net
Again, as mentioned in paragraph 3.2-, the technician must install the machine to the electrical
power supply before the machine is turned on. In case the machine comes without plug (usually it comes
without it), the technician will need to install a plug or a multiple connector/strip on the electrical cable.
Moreover, it is important for the technician to verify that the local has a proper ground and connect
the machine only to a socket with ground available. The machine comes with a proper ground point and
three labels (see the sign below) indicate these ground points in the machine.
4.5.- Security valve
The machine has inside a boiler that permits it to have hot water and steam. This boiler has a
security valve installed on the top, which will release steam in case the pressure goes up (more than 1,8
Bar). This is the first security system of the machine, to avoid pressure inside the boiler going up.
4.6.- Vacuum valve
The vacuum valve is also installed on the top of the boiler. It permits the machine to get rid off the
vacuum effect that appears inside the boiler after the steam pressure goes down. Doing this way, the
suction of liquids by the boiler is eliminated when the machines starts-up again.
4.7.- Expansion valve
This expansion valve (expansion-retention) is the second security system in the machine. This
valve is placed under the service tray (see component 7, paragraph 3.1) and permits the machine to retain
the water inside the system (retention valve) and at the same time to release water in case the pressure
of the pump/system is higher than 1.500 kPa (10,5 Bar). This double security system makes the coffee
machines 100% safe for the end user. IMPORTANT: Under no circumstances must end users
manipulate this valve. Only a high qualified technician must have access to it!!!
4.8.- Water level inside the boiler
The level of water inside the boiler is automatically controlled by the machine. The end user does
not need to do anything regarding this matter. He will only see the green light ON when the level is OK
and the orange light ON when the machine is filling the boiler.
The red light indicates that the heating is working, so the water is being heated inside the boiler to get the
right pressure (100 kPa) to provide the user enough steam to froth the milk, etc.
4.9.- Internal insulation
The machine is equipped with double insulation on its internal wiring, to provide security to
technicians when operating or servicing the machine, as well as for end users, etc.
