4 MACHINE INSTALLATION

The installation is to be carried out exclusively by qualified specialists, according to the following instructions and in compliance with valid laws.

The following chapters deal with the preparation of the machine, its electrical connection, water supply connection and drainage connection.

4.1 Preparation for installation

• Place the machine on an even and stable surface. You can regulate the height by adjusting the feet of the machine.
• Never place the machine on hot surfaces.

4.2 Electrical connection

- The electrical connection has to be conducted by authorised specialty dealers.

4.3 Water supply connection

Important

Make sure that the water supply installation is connected to a potable water supply with an operating pressure with max 3 bars. In case of an operating pressure of more than 1.5 bars, use a pressure regulator.

Please note that often the pressure of the water supply varies. If the water supply pressure temporarily exceeds 1.5 bars, use a pressure regulator. Furthermore, a shut-off valve should be used. This valve should be located where it is easily reached, so that the water supply can be interrupted at any time.

Important

• Connecting the machine to a fixed water connection and installing the pressure regulator has to be carried out by authorized service personnel.
• In order to avoid a premature calcification of your machine, we recommend to install a water softening system.

5 FIRST USE

5.1 First use

Read the instruction manual carefully prior to operating the machine.

Prior to starting the machine, check if:

• The steam and hot water valves are closed.
• The machine is switched off. (On/Off dial in position 0.)

Now you can start up your machine:

Switch the rotary dial to position 1, so that the boiler is filled. The boiler is filled as soon as the pump stops. Now switch the rotary dial to position 2. This makes sure that the machine is filled with water only when heated up. Press the P-buttons of each brew group to release water.

Caution!

The heating element can burn if the machine is heated up without being filled with water (rotary dial at position 2).

5.2 Programming of the dosage

To program the doses, proceed as follows:

Choose a porta filter and fill it with the desired quantity of ground coffee for the button you would like to program (e.g. filter 1 cup for porta filter 1 cup: 7g coffee, button no. 1). Place a cup under the porta filter.

P 1 1 2 2 D

Please note: When the left control panel is programmed, all other control panels are automatically programmed/overwritten synchronously. If you would like to program the control panels individually, it is mandatory to start programming with the left control panel and then proceed to the next.

1 Press the P-button until the lamp above the button flashes.

2 Choose the button you would like to program and press it for a short time. Coffee is released into the cup.
3 As soon as the desired quantity of coffee is reached, press the button again. Thus, the dose for the chosen button has been programmed.
4 The button for hot water is programmed in the same manner as the coffee buttons.

• Please note that the doses can vary if different quantities of coffee are used for coffee preparation or if the imposed pressure on the coffee is different while tamping.
• Every button can be re-programmed at any time.

5.3 Activation of the pre-infusion

During pre-infusion, the coffee grounds are dampened prior to the espresso extraction and slowly well up. This makes the coffee puck more stable and keeps it from being destroyed by the high brewing pressure. Furthermore, the oils and aromas are able to develop prior to extraction.

Please follow below steps to activate the pre-infusion:

Only the left brew group is used to set up pre-infusion.

1 The machine is turned off.
2 Depress button 2 (1 espresso) and switch the machine on. The lamp of that button becomes illuminated. Release the button.

3 Turn the machine off.

4 When the machine is then switched on again, the pre-infusion on all brew groups is activated on buttons 2 (1 espresso) and 3 (large cup) only. No provisions for a pre-infusion have been made for buttons 4 and 5.

5.4 Deactivating the pre-infusion

Please follow below steps to deactivate the pre-infusion:

Only the left brew group is used to deactivate pre-infusion.

1 The machine is turned off.
2 Depress button 3 (1 large cup) and switch the machine on. That button becomes illuminated. Release the button.
3 Switch the machine off.
4 When the machine is then switched on again, the pre-infusion on all_ brew groups is deactivated.

6 USE OF THE MACHINE

6.1 Preparation of the machine

The switched off machine is to be placed in operation as follows:

1 Make sure that there is water pressure in the supply hose.
2 Turn the machine on (power switch in position "2").
3 Wait until the pressure gauge indicates approx. 1.0-1.25 bar.
4 Depending on the ambient temperature, the heating-up phase is approx. 45 minutes.

5 The machine is now ready for use.

6 Before preparing the first coffee, clamp the porta filter into the brew group and press the desired button of the control panel. Release some water from the brew group. This way, the porta filter has an optimum temperature.

7 The regulation of the pump pressure takes place via the adjustment screw at the bottom of the machine (Pic. 1). In order to read the current pump pressure, insert the porta filter with blind filter into any of the brew groups and press the P-button. The current pump pressure can be read from the gauge. Stop the water flow by pressing the P-button once again. Now start the adjustment of the pump pressure and repeat point 7 until the desired pressure has been reached. The pump pressure changes with the change in the plumbing pressure.

It is recommended to leave the porta filter in the brew group, keeping it warm for optimum temperature for coffee dispersion.

6.2 Preparing coffee

Use the porta filter with 1 spout and the corresponding filter (1 cup) for the preparation of 1 cup. Use the porta filter with 2 spouts and the big filter (2 cups) for the preparation of 2 cups.

1 For espresso, i.e. Café Crème, fill the finely ground coffee into the corresponding filter. (approx. 7 – 8g per cup).

Please make sure that the filter is inserted firmly into the porta filter.

2 Somewhat compress the ground coffee with a tamper, without applying too much pressure.
3 Clamp the porta filter firmly into the brew group.
4 Place the cup under the spout of the porta filter. (For the preparation of 2 cups, put 1 cup under each spout.)
5 Press the button with the programmed dose of coffee you would like to brew. As soon as the programmed dose is reached, the filling stops automatically and the remaining water is released into the drip tray. Remaining pressure / water is released through the lower portion of the brew group.

• Only freshly ground coffee allows for an optimal coffee result. Therefore, use a professional coffee grinder. In our assortment you will find several professional coffee grinders.
  • We recommend to use a stainless steel tamper with a diameter of 58 mm for optimum tamping.

6.3 Dispensing of hot water

1 Place an adequate water container (with a heat-insulated handle) under the hot water dispenser.
2 Press the hot water button on any of the control panels in order to release a pre-programmed amount of hot water and the release will stop automatically. The release of hot water can be stopped ahead of time by pressing the hot water button again.

Caution!

Place the nozzle of the dispenser into the water container in order to avoid injuries due to hot water sprayings.

The cold water mixing valve allows for an individual adjustment of the hot water temperature (pic). It is located at the middle part of the machine, below the drip tray.
