Table W 3. Maximum non-scaling Hardness (mg/l) by temperature and Alkalinity. With an Alkalinity of
50, ideal hardness would be about 100 mg/l for the coffee boiler (90-95 degrees) and about 30 mg/l for
the steam boiler (125 degrees). We advise to use 100 mg/l hardness at 50 mg/l Alkalinity. Source: Jim

Note on this manual
Work on the Mirage manual (touchpad version) is a continuing process. Photographs in the manual
are taken in the shop from machines being built or from parts available, they range from 2012 to 2016.
For that reason, body panels and/or parts from the machines on display may be missing and parts in
the machine you bought some time ago may not look identical to the parts shown in the manual. Over
time, sections are added and/or improved, sometimes as result of readers making comments. If you
have suggestions for improvements, do not hesitate to send them to:
