Î Determine the refill quantity - subtract
the filling level value you have read from
75 l. In the example: 75 l – 35 l = 40 l.
Î From the dosing table, find out the re-
quired quantity of the corresponding
chemicals. In the example: 4 times the
quantity for 10 l water.
Î Measure the ascertained quantity of the
corresponding chemical and fill it into
the dosing container.
Î Fill up the dosing container up to the
mark "75 l" with chlorine-free water.
