3.2 Heating

The  Yeast-Booster  heats  the  water  to  the  required  temperature  (e.g.  38,5  °C)  and
enriches  the  mixture  simultaneously  with  Oxygen  (filtered  air).  The  YB  indicates  by
light signal and on its display when the set temperature has been reached. Now you
can  add  the  dry  yeast,  mixing  it  slowly  and  carefully  with  the  hand-mixer  provided
with the unit.

Attention!
Never  leave  the  Yeast-Booster  on  heating  mode  when  empty,  for  risk  of
damaging to the heat-exchanger.
