6. Structural components 6.1 Coffee grinder The service life of the grinding wheels is approx. 80.000 grinding processes (1 grinding process = approx. 10 g). The grinding capacity on the finest setting is approx. 180 g/min, i.e. roughly 3 g/s. The grinding capacity decreases as the wheels begin to wear down. The grinding process is timer-controlled, which means that less ground coffee is dispensed as the grinding wheels begin to wear down.
6.1.2 Weighing the ground coffee Weighing without dismounting the housing Please note that slight deviations are possible due to ground coffee remnants in the brewing unit. . Place a sheet of paper or filter bag in the grounds container. . Press the desired article key. Grinding takes place and ground coffee is metered into the brewing cylinder. . Switch the machine off and on again: - after the grinding process, - immediately after opening the brewing valve.
6.1.4 Replacing the grinding wheels Replace the grinding wheels: - after approx. 80.000 grinding processes, - if the grinding capacity is still only about 80-100 g/min (approx. 1.5 g/s) on the finest setting, - if grinding becomes uneven. Disconnect machine from mains! Adjusting ring O-ring Catch . Take coffee beans out of coffee grinder. . Release catch. . Unscrew adjusting ring. . Replace both grinding wheels. Assembly . Replace old O-ring with a new one. . Clean screw thread.

6.2 Brewing unit 6.2.1 Operation of brewing unit Calibration process Photoelectric barrier for measuring distance travelled (encoder) The brewing group is calibrated every time the machine is switched on. This involves measuring the upper and lower limit positions of the plunger, then calculating and storing the distance between the two. Go to photoelectric barrier for reference point Procedure: Upper brewing plunger with needle filter 2.
Brewing sequence After having pressed the product key: 1. Coffee is ground and falls into the brewing cylinder. 2. ”Upper brewing plunger” moves down until it is a set distance away from the ”lower brewing plunger” depending on the required article. The machine checks whether the metered quantity of ground coffee is sufficient by attempting to recompress it with the ”upper brewing plunger” at reduced motor power( ”bean container empty” signal). The grinder of the assigned product keys gets blocked.
Filter and plunger position for espresso Espresso Do not cross the tube length of 250 mm! Upper brewing plunger Annular gap approx. 0.05 mm Compression spring Compressed ground coffee Needle cushion and perforated disc pressed togehter Lower brewing plunger Brewing water Do not cross the tube length of 500 mm! Automatic cleaning of brewing unit (duration: approx. 5 minutes) After confirmation that the cleaning tablet has been added: 1.
Notes Cleaning If the automatic cleaning sequence is interrupted by switching off the machine or disconnecting the power supply, it is resumed as soon as the machine is switched on again and the command ”Add cleaning tablet” appears. The automatic cleaning sequence must be completed. If, during a working time of 24 hours, cleaning has not been carried out the display box will show the request “Clean machine”.
6.2.3 Checking/adjusting the brewing unit . Carry out functional test. Supporting element . Subject all parts to a visual inspection for signs of wear, breakage or stiffness, e.g.: - O-rings, - strainers, - springs, - hoses, plug-in connectors, screw joints, - wipers, - guides. Nut Checking 48 mm measurement - Permissible deviation -0.
Checking 36 mm measurement Supporting element Driving rod 36 Nuts Plain washer - Permissible deviation +/-0.5 mm. - Above 36 mm: ”lower plunger” possibly moving upwards too late - wiping occurs before ”lower plunger” has reached the upper limit position. - Below 36 mm: ”lower plunger” possibly moving right to the stop ”upper plunger” cannot move up far enough, so that reference point is not reached. Setting 36 mm measurement - Permissible deviation +/-0.

The dispensed quantities of coffee and milk/milk froth are divided in the dispenser rocker, thus allowing 2 cups to be filled simultaneously. The coffee dispenser is locked when the dispenser block is pulled out. The pin on the dispenser block actuates the microswitch on the holder guide.
6.19.2 Adjusting the milk froth dispenser Depending on the sort of milk or its quality, it is necessary to modify the air supply for milk frothing. There are two different air nozzles enclosed. One air nozzle is already inserted under the keypad cover.

6.20 Emptying of Boilers (VIVA TRAIN) This function serves the VIVA coffee machines execution TRAIN for the protection from the freezing damage. The water in the construction units would freeze and these otherwise would damage. The mechanism “Emptying of Boilers” is operated over a advised halogeneous− free control line with a tension by 110V DC (DC voltage). Over the control line relays are headed for, which empty the storage water heaters/boilers (see illustration).

10.11 Functional Description VIVA au lait, Type 810 . . . Functional Description The VIVA au lait has two valves more than the VIVA standard design. The single solenoid valves sit in contrast to the standard design directly on the hot water/steam boiler. The steam valve Y8 is used additionally for the heating up of milk and provides for an optimal expenditure temperature of approx. 71 degree C, for the product milk. The additional steam pipe waives the Injectorprinzip.

10.12 Functional description VIVA au lait, type 807, 813 . . . Functional description The VIVA au lait has two more valves than the VIVA standard-model. As opposed to the standard model, on the VIVA au lait the magnetic valves are seated directly on the boiler. This results in a significant reduction of condensation build-up. The steam valve Y9 is for blowing the milk pipe clear of milk residue, always after dispensing the product.
