Chapter Six: Regular Use and Maintenance
The single biggest problem with boilers is the build up of scale resulting from dissolved solids within the beer.
Scaling can cause the heating elements to fail, the beer level sensors not to function, and premature failure of the
O-rings resulting in leaks from around the elements. The extent of the problem will vary according to the degree
of impurities in the beer.
* IMPORTANT NOTICE: DO NOT ATTEMPT TO RUN ANY MASH OR LIQUID WITH SUSPENDED
IMPURITIES DIRECTLY THROUGH THE EB120 WITHOUT FIRST STRAINING AND FILTERING.
DOING SO WILL CLOG THE BEER PUMP, SOLENOID VALVE, AND BOILER, AND WILL VOID
YOUR WARRANTY. WE RECOMMEND PRE-SCREENING WITH A FINE STAINLESS STEEL
SCREEN, THEN FILTERING WITH AT LEAST A 10-MICRON FILTER BEFORE ALLOWING YOUR
BEER TO BE PUMPED INTO THE EB120.
We also recommend descaling the boiler once every 50 to 100 hours of operation. To descale use a solution of
weak acid crystals (such as citric acid) mixed with water. Citric acid crystals are available in packets for descaling
