◆ Calcium and magnesium determine the hardness of the water and cause the formation of what we
simply call scale. Water is hard from 30 °f to 40 °f; it is considered very hard from 40 °f upwards. The
hardness can be measured by simple test kits, which may be purchased at any service centre.
◆ There is a small resin water softener (plus one in the accessories kit) inside the water tank, which
should be replaced or regenerated once every 20-30 litres of water that are used.
The small water softener can be regenerated by putting it in salt water (0,5 litres and one spoonful of
NaCl, sodium chloride) for approx. 48 hours. Thoroughly rinse with clean water and put the small
water softener connected to the silicone tube back inside the tank.
11. PRACTICAL INFORMATION AND SUGGESTIONS
We recommend water hardness between 15 and 30 French degrees (check
with your help centre). If the value is greater than or less than the recommended
parameters, periodic checks and a special cleaning of the hydraulic circuits by specialized
technicians are required.
Depending on the geographical location and a possible period of inactivity, it's recom-
mended a specific cleaning of the hydraulic circuit by qualified personnel.
◆ For best results, use ground coffee for bar use, which has a well-defined coarseness of grinding. Give
this grinding indication to your coffee roaster or shop when asking for your favourite blend.
◆ If the optional adapter is fitted, you can also use pre-packaged coffee pods. The use of coffee pods
offers many advantages: the freedom to choose from among the many brands on the market, a con-
stantly good espresso irrespective of the experience of whoever is making it, extremely easy to use and
lastly, less maintenance because the appliance remains constantly clean.
◆ To enjoy excellent coffee:
- purchase a good brand of coffee in beans.
- keep the coffee in beans in a dry place.
- grind the coffee beans fresh when you make coffee.
- measure and press the ground cofffe slightly to pack it more uniformly.
◆ For boiling hot cofffe:
- leave the filter holder with the empty empty filter in the coffee distribution unit at all times.
- rinse the filter holder and filter with boiling hot water by pressing the coffee switch.
- use the same boiling water to pre-heat the cups.
◆ For a delicious cappuccino:
- use a tall narrow milk pitcher half full.
- immerse the steam nozzle 1 cm into the milk.
- open the steam tap with the knob.
◆ If you just want to heat the milk:
- immerse the steam nozzle all the way into the milk.
- open the steam tap with the knob.
- close the steam tap when the milk is hot enough.
