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 automatically reaches an intermediate position between MIN and MAX on the level indicator (23).
• Once the automatic water-filling procedure is complete, press the maximum power button (3) to switch on the heating element to heat the water (Geniale “M” version only).
• 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 (7).
• If the machine does not stabilize at the values indicated, you should adjust the pressure switch as indicated in paragraph 6.1.
• Check the pressure on the pump pressure gauge (12) 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 6.2.
• The machine is now ready for use.
• 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.
• Regularly check the amount of water in the boiler, which should not fall below the MIN level of the indicator (23); if necessary, top up the level by pressing the boiler water-filling button (9).
  • 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 authorized service center.

During start-up:
When the boiler pressure gauge (7) indicates approximately 0.5 bar, slowly open the steam knoblever (14-20) to discharge any air that may be contained in the boiler. Wait until steam starts to come out of the steam wand (11) 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 (7).

PRESSURE SWITCH (Geniale “M” version only)
The function of the pressure switch shown in the figure is to keep the pressure in the boiler constant by activating or deactivating the electric heating element. The pressure switch is adjusted to 1.1 ÷ 1.3 bar when the machine is tested.

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 coffee at the right temperature. We therefore recommended that before using them, you place the cups on the cup warmer shelf (19), which will be warmed by the heat given off from the boiler. On machines fitted with an electric cup warmer, cups are pre-heated by pressing the button (8); the light inside the button will turn on to indicate that the cup warmer is in operation. Press the button (8) 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 (22), fill the filter with the amount of coffee required for 1 or 2 cups (7 g – 14 g), then 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 (21), 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 (17). Once the required amount of coffee has been dispensed, stop delivery using the group head control (17) and leave the filter-holder in place. To prepare additional cups of coffee, remove the filter holder (22) 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 filter holders, together with the filters and coffee grounds, in the group head so that the filter holder will always be at the right temperature.

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

Place a container under the hot water dispensing tap (13), press the button (15) to dispense the water and then add the bag/sachet of the drink to prepare.

CLEANING AND MAINTENANCE

CLEANING THE STEAM WANDS
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.

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

WEEKLY CLEANING

CLEANING THE GROUP HEAD AND SPOUTS
Remove the filter holder from the group head. Place the membrane provided into the filter, add a spoonful of coffee machine cleaning powder and insert the filter holder (22) into the group head to be cleaned (21). Use the group head control (17) to start dispensing and stop delivery after approximately 4-5 seconds. Start and stop delivery alternately for approximately one minute to remove coffee 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.

CLEANING THE FILTERS AND FILTER HOLDERS
Regularly check the holes in the filters in order to remove any coffee deposits. Place approximately one litre of boiling water and four teaspoons of coffee machine cleaner in a suitable container. Immerse the filters and filter holders in the solution for 20-30 minutes. Then rinse thoroughly under running water.

CLEANING THE LOWER DRIP TRAY
Remove the drip tray grid (25) and the drip tray (24). Remove any coffee residues from it.

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.

REPLACING THE GROUP HEAD GASKET
If the coffee leaks from around the edges of the filter holder when it is dispensed, it may be due to an obstruction in the delivery hole of the filter- holder, in which case the hole should be cleaned. If the problem persists or if the group head moves significantly beyond the centre of the group head when it is being fitted, the group head gasket should be replaced. To replace it (Fig. 3), loosen the spout fixing 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.

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 (25) and the lower drip tray (24). Open the drain tap placed under the sight glass (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.

USING THE WATER SOFTENER

The procedures described below refer to the water softener shown in the figures. If your appliance is not the same, follow the instructions attached to the 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:
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
• Move the lever (d) from right to left.
• Do not use the machine during the regeneration cycle. For machines equipped with an automatic water level device, 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.

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.
