5. STARTING THE MACHINE FOR THE FIRST TIME

• Once the hydraulic and electrical connections have been completed, the machine can be started up. Open the water tap (A).
• Turn off the circuit breaker (D).
• Press the power on button (1); the power on light will come on.
  •The automatic water level device will start

filling the boiler with water until it reaches the pre-set level; the level of water in the boiler is checked automatically and will be topped up automatically to the required level.

- When filling the boiler for the first time, the filling timeout may be triggered (flashing of the LEDs on the keypads); this is normal because filling an empty boiler takes longer than the set safety timeout (120 s).

Switch the machine off and on again using the main power switch. The machine will continue to draw in water until it is full. N.B. This process may be repeated two or three times.

Do not switch on the heater power switch (2) until the boiler is filled to the correct level.

- When the automatic water filling process has finished, press the switch (2). This will switch on the heating element to heat the water.

- Wait for the machine to reach the operating pressure of 1.1 ÷ 1.3 bar, checking the pressure of the boiler on the pressure gauge (11). If the machine does not stabilise at the values indicated, you should adjust the pressure switch as indicated in paragraph 5.1.

- Check the pressure on the pump pressure gauge (11) by operating a group head with the filter holder inserted and full of properly ground, dosed and pressed coffee, to obtain an effective operating pressure of 8/9 bar. If you need to adjust the pump pressure, follow the instructions in paragraph 5.2.

If there is no water in the boiler when the machine is in operation, the heating element will fail. This must be replaced by an authorised service centre.

During start-up:

when the boiler pressure gauge (11) indicates approximately 0.5 bar, slowly open the steam knob/lever (13) to discharge any air that may be contained in the boiler. Wait until steam starts to come out of the steam nozzle (12) before closing it. Wait until the machine reaches the operating pressure and the correct thermal balance, after 35-45 minutes.

Do not press the hot water dispensing button or turn the tap before the correct operating pressure of 1.1 bar has been reached, indicated on the boiler pressure gauge.

Wait for the machine to reach the operating pressure of 1.1 ÷ 1.3 bar, checking the pressure of the boiler on the pressure gauge (11). If the machine does not stabilise at the values indicated, you should adjust the pressure switch as indicated in paragraph 5.1.

The machine is now ready for use.

5-1. PRESSURE SWITCH

The function of the pressure switch shown in Fig. 5 is to maintain a constant pressure in the boiler by activating or deactivating the electric heating element.

This pressure switch is set to a value of 1.1 - 1.3 bar during the final test of the machine. However, if a specific application requires a different working pressure, the working range of the pressure switch can be modified using the adjusting screw (U): reducing the pressure reduces the temperature, increasing the pressure increases the water temperature. The direction of adjustment is indicated in the figure and on the pressure switch. The pressure changes by approximately 0.1 atm for each complete turn of the screw.

Caution! Disconnect the power supply before performing this operation.

5-2. CALIBRATING PUMP PRESSURE

• Insert the filter holder full of properly ground, dosed and pressed coffee into the group head. Turn on the switch or use the group head control keypad (15) and read the pressure on the pump pressure gauge (11).
• The correct pressure is 8/9 bar. If the reading on the pressure gauge is incorrect, turn the pump pressure adjustment screw Fig. 6 (Z) clockwise to increase the pressure or anti-clockwise to decrease the pressure. After regulating the pressure, check the pump setting by delivering one or more coffees.

6. PREPARING COFFEE

• To obtain a good cup of espresso coffee, it is important that you use good quality, well roasted and correctly ground coffee. Grinding is optimal when it takes 15-18 seconds for one cup and 30-35 seconds for two cups to be delivered.
• Coffee should be ground just before it is used. Once ground, coffee loses its flavour very quickly. If the coffee is too coarsely ground, the coffee will be light coloured and weak without

froth and if the coffee is too finely ground the espresso will be dark and strong with little froth.

• Warm cups help maintain the coff ee at the right temperature. We therefore recommended that before using them, you place the cups on the cup warmer shelf (16), which will be warmed by the heat given off from the boiler.
• The new BarT is fitted with an electric cup warmer, cups are pre-heated by pressing the button (18); the light inside the button will turn on to indicate that the cup warmer is in operation. Press the button (18) again to switch off the cup warmer.

Do not cover the cup-warming shelf with fabrics, felt etc.

• After placing the filter in the filter holder (6), add the quantity of ground coffee required for 1 or 2 cups (7 g - 14 g), level the coffee and compact it using the tamper. Remove any coffee residues from the edge of the filter using the palm of your hand and insert the filter holder into the group head (5), moving it towards the right to secure it.
• Place the cups under the spouts and start to dispense coffee using the group head control lever (15).

Once the required amount of coff ee has been dispensed, stop delivery using the group head control (15) and leave the filter-holder in place.

- To prepare additional cups of coffee, remove the filter holder (6) from the group head by moving it towards the left, empty the coffee grounds into the drawer and repeat the steps described above.

Do not touch the group heads or the steam and hot water nozzles when the machine is in operation and do not place your hands under the groups or nozzles during delivery in order to avoid possible scalding.

It is recommended to leave the fi lter holders, together with the fi lters and coff ee grounds, in the group head so that the fi lter holder will always be at the right temperature.

When the machine is new, the fi lter holder may not be aligned (perpendicular to the machine) as shown in the fi gure. However, this however does not prevent the machine from working properly. After being used for a short time, the fi lter holder will gradually become settled in the correct position.

7-1. COFFEE DOSE PROGRAMMING INSTRUCTIONS

Fig. 3 GROUP HEAD CONTROL Button functions:

A. 1 normal coffee
B. 2 normal coffees
C. 1 long coff ee
D. 2 long coffees
E. Stop group head controls / continuous delivery.

The button 📄) is used for continuous delivery and to stop delivery. Therefore the machine has a double function:

A. Pressing the button 🎨(E) places the machine in semi-automatic mode
B. Pressing the 4 selection buttons operates the machine in electronic volumetric dosing mode.

Pressing and holding the button 📄E) for a few seconds places the machine in programming mode. This is indicated by the slow fl ashing of the LED corresponding to the group head that is being programmed. Release the programming button (the LED will continue to fl ash); press the button of the group head on which you wish to program coff ee dosing. Once the required dose has been reached, press any button of the same group head to stop delivery. The dose will be stored in the memory and the machine will exit from programming mode (the fl ashing LED will switch off).

• This should be repeated for the remaining selection buttons of the various group heads. Repeat the same procedure if you wish to increase or decrease the set dose. Programming the first group head on the left will copy the settings onto the other group heads.
• The settings entered for group head 1 (via the first keypad) will be copied automatically to group head 2.

7-2. PRE-INFUSION

Our software allows confi guring the dosage so that the volumetrically controlled doses of coff ee is preceded by pre-infusion.

After time 1 (ON), coffee dispensing stops for time 2 (OFF) and then continues until the selected dose has been dispensed completely.

If you press one of the volumetric controlled dose buttons, the normal dispensing cycle is preceded by a short timed jet of water to dampen the coff ee dose before actual dispensing takes place. This function ensures the optimum use of the coff ee dose.

ACTIVATING PRE-INFUSION

Switch on the machine with the main switch, keeping button (A) of group head 1 pressed until the LED of button 🎨 (E) lights up. Switch the machine off and on again. Pre-infusion has been started.

DEACTIVATING PRE-INFUSION

Switch on the machine with the main switch, keeping the button (B) of group head 1 pressed until the LED of button (E) lights up. Switch the machine off and on again. Pre-infusion has been deactivated.

8. DISPENSING COFFEE

• To dispense coff ee, press the required button on the group head control (15), the green LED on the button (E) lights up. Coff ee delivery starts and stops automatically when the pre-programmed quantity is reached. The LED turns off to indicate the end of delivery.
• Delivery can be interrupted or the selection cancelled by pressing any of the group head control buttons (15).
• In addition to interrupting delivery and cancelling the selection, the button (E) also has a continuous delivery function. This means that the dose is not pre-set and that the group head will continue to deliver coffee until the button is

pressed again, which stops delivery.

• If the coff ee is too finely ground or if there is too much coff ee in the fi lter, no coff ee will be dispensed when one of the four coff ee dosage buttons (A, B, C, D) is pressed. After 45 seconds, the machine will automatically lock and the steady green LED will start fl ashing.
• To restart the machine, remove the fi Iter-holder and replace the coffee in the fi Iter basket. Press the main switch (1) to switch off the machine and then restart it.

We recommend that you dispense steam for a maximum of 60 seconds. To prevent the machine from blocking, if coffee does not start to be dispensed within 10 seconds, press one of the selector buttons to cancel the command, replace the coffee in the filter and repeat the dispensing procedure.

To prevent the machine from blocking, if coff ee does not start to be dispensed within 10 seconds, press one of the selector buttons to cancel the command, replace the coff ee in the filter and repeat the dispensing procedure.

9. DISPENSING HOT WATER

Place a container under the hot water delivery nozzle (3), press the hot water button (4); when the required amount of water is obtained, press the button again to stop dispensing.

We recommend that you dispense steam for a maximum of 60 seconds.

10. PREPARING OTHER DRINKS

10-1. MILK, CAPPUCCINO AND OTHER HOT DRINKS

Before heating any drinks, carefully dispense a small amount of steam from the steam nozzle (12) by turning the steam knob (13) anticlockwise to eliminate any condensation that may have formed in the boiler.

Place the liquid to be prepared in a container, immerse the steam nozzle (12) into the liquid and slowly turn the steam knob (13) anticlockwise.

Then open the steam knob completely to dispense a large quantity of steam that will bring the liquid to boiling point. To froth milk for a

cappuccino, half fi ll a tall narrow container with the milk to be prepared.

Immerse the steam nozzle (12) until it touches the bottom of the container and bring the milk almost to boiling. Move the container up and down with the tap open until you just touch the surface of the milk for a few seconds, until the froth has formed. To make a cappuccino, add the hot frothed milk to the hot coff ee that is already in the cup.

10-2. TEA, CAMOMILE TEA

Place a container under the hot water delivery nozzle (3), press the hot water button (4). When the required amount of water has been obtained, add the tea bag or drink sachet required for the preparation.

11. CLEANING AND MAINTENANCE

11-1. CLEANING THE STEAM NOZZLES

To avoid altering the taste of the drinks to be heated and to prevent the holes at the end of the steam nozzle from becoming clogged, we recommend cleaning the nozzle thoroughly after every use.

11-2. DAILY CLEANING

Rinse the fi Iter baskets and fi Iter-holders in boiling water to prevent scale or remove coffee deposits and clean the shower screens of the group heads.

12. WEEKLY CLEANING

12-1. CLEANING THE GROUP HEAD AND SHOWER SCREENS

Remove the fi lter holder from the group head. Place the membrane provided into the fi lter, add a spoonful of coff ee machine cleaning powder and insert the fi lter holder (6) into the group head to be cleaned (5). Use the group head control (15) to start dispensing and stop delivery after approximately 4-5 seconds. Start and stop delivery alternately for approximately one minute to remove coff ee and limescale deposits. Remove the membrane and start dispensing several times in order to rinse the group head. Dispense several cups to eliminate unpleasant tastes from the spouts and the group head. After hot water has remained in the pipes for a long time, allow water to flow downwards to remove any deposits.

12-2. CLEANING THE FILTERS AND FILTER HOLDERS

Regularly check the holes in the fi Iters in order to remove any coff ee deposits. Place approximately one litre of boiling water and four teaspoons of coff ee machine cleaner in a suitable container. Immerse the fi Iters and fi Iter holders in the solution for 20-30 minutes. Then rinse thoroughly under running water.

12-3. CLEANING THE LOWER DRIP TRAY

Remove the drip tray grid (8) and the drip tray (7). Remove any coffee residues from it.

12-4. CLEANING THE OUTSIDE OF THE MACHINE Use a damp, non-abrasive cloth, without alcohol or solvents, to avoid damaging the sides, the base and any painted parts.

IMPORTANT! The machine must not be immersed in water and should not be cleaned with jets of water.

13. REPLACING THE GROUP HEAD GASKET

If the coff ee leaks from around the edges of the fi Iter holder when it is dispensed, it may be due to an obstruction in the delivery hole of the fi Iter-holder, in which case the hole should be cleaned. If the problem persists or if the group head moves signifi cantly beyond the centre of the group head when it is being fi tted, the group head gasket should be replaced.

To replace it (Fig. 2), loosen the spout fi xing screw (E), remove the spout (C) and the sprayer (B). Then use a screwdriver as a lever to remove the round metal block (A) and then the gasket (D).

After having removed the gasket, thoroughly clean the seat before inserting the new gasket.

Then reinstall the components by following the above steps in reverse order.

14. REPLACING THE WATER IN THE BOILER

The water contained in the boiler should be replaced every 15-20 days in order to eliminate iron bacteria and various residues that build up due to water stagnation.

Turn off the main switch (1), remove the drip tray grid (8) and the lower drip tray (7). Open the drain tap located in the lower left opening (with the boiler under pressure) and allow the water to drain completely from the boiler. Close the tap and repeat the start-up procedure described in another section of this manual.

15. USING THE WATER SOFTENER

The following instructions apply to the water softener illustrated; if your appliance is different, follow the instructions supplied with the water softener.

Calcium and magnesium contained in the water circulating inside the boiler and the group head circuits damage the machine. The function of the softener is to dissolve the calcium and magnesium and make them settle out on the resins contained in the softener.

To prevent the build-up of deposits from saturating the resins, and thereby limiting their function, they should be regenerated at regular intervals according to the following criteria:

- 8-litre softener for water with a hardness of 40 French degrees:

• up to 400 cups of coffee/day, every 10 days
• up to 800 cups of coffee/day, every 5 days
• up to 1000 cups of coffee/day, every 3 days

- 12-litre softener for water with a hardness of 40 French degrees:

• up to 500 cups of coffee/day, every 15 days
• up to 1000 cups of coffee/day, every 7 days
• up to 1500 cups of coffee/day, every 5 days
• up to 2000 cups of coffee/day, every 3 days Delaying regeneration and therefore allowing scale to build-up, may affect the thermal and mechanical functions of the machine and the taste of the coffee. To regenerate the resins proceed as follows:

g sale a c and b d f

Place an empty container, having a capacity of at least two litres, under the pipe (e), turn the levers (c) and (d) to the right; unscrew the lid (g) and wait for the water to drain completely from the hose (e). Add 1.5 kg of cooking salt for the 8-litre model or 2 kg of salt for the 12-litre model. Replace the lid and turn the lever (c) from right to left; allow the salted water drain from the hose (f) until the water has become soft again (the cycle takes

approximately 90 minutes).

a Water inlet
b Water outlet
c Inlet tap
d Outlet tap
e Vacuum pipe
f Regeneration pipe
g Lid knob

• Do not use the machine during the regeneration cycle. It is recommended to disconnect the power supply to the pump, to prevent it operating dry.
• Wash the resins before connecting the softener to the machine by connecting to the water supply and allowing the water to run for five minutes.

16. SCRAPPING THE MACHINE

If you decide you no longer wish to use the machine because of wear or for other reasons, we recommend making it unusable by cutting the power cable after having removed the plug from the socket.

When scrapping the machine, we recommended separating the various parts according to their material (plastic, metal etc.). Then give the various parts of the machine to specialised companies for disposal.
