6.14 Suggestions on how to obtain a good

cup of coee Wash daily the lters and lter carrier as instructed in Par. 7.6.3 on page 45. Failure perform this operation will compromise the quality of the coee dispensed. To obtain high-quality coee, it is important that the hardness of the water used does not exceed 6-7 °f (French degrees). If the water hardness exceeds these values, it is advisable to use a water lter or softener. Avoid using a water softener if the water hardness is less than 4 °f. If the taste of chlorine in the water is particularly strong, a special lter should be installed. Do not to store large amounts of coee beans. If the type of coee is changed, contact the Manufacturer's Qualied Technician for the water temperature and grind adjustment. After the machine has not been used for a certain period of time (2-3 hours) carry out a few dry runs. Be sure to carry out regular cleaning and maintenance.USER manual ENGLISH 41 of 160
