****Remove the drainage tray to facilitate the task and lead the tube to the drain through the opening at the base of the machine and connect the tube to the fitting in the tray.
Then, lead the end of the tube to the drain.
It is important that the drainage tube is completely straight with no angles in order to facilitate good drainage.
Connect the machine plug to the appropriate connection base according to the current electrical standards of the area.

****You should not use extension cords or outlet adapters of any kind to connect the machine to the electricity network.
The network connection cable should never be rolled up; instead, it should be fully extended to avoid possible overheating.

Press the main power switch.
At start-up the electronic control box detects that there is no water in the boiler and activates the filling valve and the pump. These remain active until the level probe detects  adequate water level. As soon as this occurs, the boiler element will switch on, heating the entire system.

If the control box does not detect an adequate water level in the boiler within 4 minutes, the onecoffee and wo-coffee LED keys will blink, indicating a water level warning. In semiautomatic machines, the Boiler Water Level indicator will blink. This warning can be cancelled by turning the machine off and on again.
Place the filter holder in the group head, press the continuous coffee button to purge the group, and let water flow out for 30 seconds. Then wait approximately 12 minutes  until the machine is at normal working temperature, observing whether the gauge indicates a pressure of 1 bar.
While the machine is heating, proceed with the installation of the grinder. Adjust the grinding fineness and doses.
Once the machine has reached working temperature and we have adjusted the grinder, we can program the coffee doses (see section 4.3, pg. 9)

4.2.2 Models with internal water tank

1. Place the machine on the workbench and open the top lid to access the water tank. Fill it with water without removing it from its housing and ensure that the filling and  suction tubes remain at the bottom. Lastly, close the lid.
   ****It is recommended to use water with a hardness between 5-8 dHº (8-14 fHº) to avoid calcification and to obtain an optimal quality of coffee and tea.

2. The internal water tank models drain the residual water in the drainage tray without an external connection to a drainage system. For this reason, they have a level  indicator.
   ****Check the level indicator and empty the drainage tray, if necessary.

3. Connect the machine to the appropriate plug connection according to the current electrical standards of the area.
   ****You should not use extension cords or outlet adapters of any kind to connect the machine to the supply network.
   The mains connection cable should never be rolled up; instead, it should be fully extended to avoid possible overheating. You should not use extension cords or outlet adapters of any kind to connect the machine to the supply network.
   The mains connection cable should never be rolled up; instead, it should be fully extended to avoid possible overheating.

4. Press the main power switch.
   At start-up the electronic control box detects that there is no water in the boiler and activates the filling valve and the pump. These remain active until the level probe  detects a correct water level. During the initial filling of the boiler, it might be necessary to re-fill the water tank several times. As soon as the probe detects a correct  water level, the boiler element will switch on, heating the entire system.
   ****If the control box does not detect an adequate water level in the boiler within 4 minutes, the one-coffee and two-coffee LED keys will blink, indicating a water level  warning. In semiautomatic machines, the Boiler Water Level indicator will blink. This warning can be cancelled by turning the machine off and on again.

5. Place the filter holder in the group head, press the continuous coffee button key to purge the group, and let water flow out for 30 seconds. Then wait approximately 9  minutes until the machine is at normal working temperature, observing whether the gauge indicates a pressure of 1 bar.

6. While the machine is heating, proceed with the installation of the grinder. Adjust the grinding fineness and doses.

7. Once the machine has reached working temperature and we have adjusted the grinder, we can program the coffee doses (see section 4.3, pg. 9)
   ****The water tank versions have an “Espresso Priority System” that allows coffee to be made only at an optimal temperature and to prioritize coffee preparation over other  machine functions.

4.3 Dose Programming

• Electronic Machines: we can program the amount of coffee on the one-coffee and two-coffee pushbuttons.
• Semiautomatic machines: do not allow for the amount to be programmed.

1. Enter Program Mode:
   With the machine turned off, hold down the continuous coffee button. Turn on the machine and wait 4 seconds with the continuous coffee key pressed until the  selection button lights turn off. Only the one-coffee and two-coffee buttons are programmable.

2. Programming the Amount
   a. Put the ground coffee or the capsule (according to the model) in the filter holder for one or two coffees and insert it into the group head.
   b. Press the program key for more than 3 seconds until the coffee begins to come out. When you have reached the desired amount of coffee, press the same key again.  Repeat these steps on the other coffee pushbutton.
   c. To exit programming mode you must turn off and turn on the machine again with the main power switch

Volume counter alarm
If we are programming the amount of coffee for one coffee and two coffees and more than 15 seconds go by without detecting counter impulses, the volume counter warning will be activated and the one-coffee and twocoffee keys will begin toblink. To turn off the blinking,  press any key,which will return  you to programming mode. If  after trying again the  warning signal appears, call a service technician.

Cleaning and Daily Care

1. Keep the machine in optimal conditions of cleanliness is a daily requirement for guaranteeing the necessary hygiene and good quality of the final beverage, as well as a longer service life for the machine.

5.1 External Cleaning
Do not use any chemical or abrasive products to clean the machine. Only use a cotton cloth moistened with water. Pay special attention to the pushbuttons and the areas  related to beverage preparation: the steam arm, the hot water outlet and the filter holder and group head.

5.2 Group Head Cleaning
Rinse the group head daily to maintain an optimal quality of coffee. To clean the coffee holder, follow these instructions:

1. Put the blind filter in the filter holder.
2. Insert the filter holder into the part.
3. Press the continuous coffee key and wait 10 seconds.
4. Press the continuous key again to stop and wait 10 seconds. Repeat this cleaning cycle until the water comes out clean through the discharge valve.

5.3 Daily Care
At the beginning of the day

1. Activate the group head for 20 seconds to purge the water in the circuit. After long periods of time without making coffee, on models with internal water tank, press the  continuous button to fill the heat exchanger and wait until the water comes out from group.
2. Check that the water comes out through the shower in a  single, continuous stream. If it does not, clean it with the blind filter. Replace the part and spout if the problem persists.
3. Remove from the grinder dispense chamber any ground coffee from the previous day.
4. Verify that the ground coffee dose and grinding point are correct.
5. Prepare a coffee and verify that it comes out correctly.

At the end of the day

1. Limit the amount of coffee to be ground to single servings since the ground coffee from one day should be discarded the next.
2. Rinse the group head with the help of the blind filter.
3. Clean the filter and the filter holder with hot water and hold it up to the light to make sure the filter holes are not obstructed. Leave the filter holder in the group head without over-tightening it.
4. Clean the steam arm with a damp cloth and purge it several times.
5. Clean the drainage tray.

Practical Advice
Warning! We recommend cleaning the water tank at least weekly so as to maintain adequate hygiene conditions.
A solution should be prepared of 10 grams of sodium bicarbonate to one litre of water.
Shake the tank with the solution inside, ensuring that any dirt is removed. If traces of scale remain, use an appropriate brush.
Empty and then rinse the water tank with plenty of clean water.
Empty the water tank if the machine is going to remain unused for more than one day.

• Do no not stack cups more than three cups high.
• Avoid reheating milk. Heat in small amounts.
• Before foaming milk, open the steam valve to purge it. Once the foaming is done, purge again and clean the tube with a damp cloth.
