(Fig. 17/11) The
solution con-
sumption used during cleaning can be
regulated in seven stages. Accordingly,
there are seven green control lamps on
the keypad. Each lamp relates to one
stage. The maximum quantity which
can be used for cleaning is 5.5 l/min (all
seven lamps are on). The minimum
quantity is 1.25 l/min (only the left lamp
is on). The last solution quantity select-
ed is always used. When the scrubbing
program is switched on for the first time,
a solution quantity of approx. 3.5 l/min
is automatically set.
