Page 52: 14�8 Starting Ice Production In
14.8 Starting ice production in kg If you want to produce a certain amount of ice in kg (ob- viously, if this amount exceeds the bin capacity, the ma- chine will stop when the bin is full), it is necessary to put the machine in standby first, if it is not already, by pressing (22).
Page 53: 14�9 Starting Programmed Ice Production
14.9 Starting programmed ice production If you want fresh and intact ice, close to the time you intend to use it, it is not enough to define the quantity, but the time must be defined too. In this way, it will be possible to make the machine produce ice close to the set time and not many hours before, thus preventing the ice from melting and being contaminated in the bin�...
Page 54 If you want to produce a certain amount of ice in kg (obviously, if this amount exceeds the bin capacity, the machine will stop when the bin is full), for a certain time over the next 3 days, it is necessary to put the machine in standby first, if it is not already, by pressing (22).
