 Determining the hardness of tap water:
– through the public water supply works,
– using a hardness tester (order no. 6.768-004)
 Remove the appliance cover.
 Open the switch box at the operating panel.
 Set the speed potentiometer (a) according to the water hard-
ness. You can refer to the correct setting in the table.
Example:
For a water hardness of 15 °dH, set 6 on the value scale of the
speed potentiometer. This results in a pause of 31 seconds, i.e.
the solenoid valve will open briefly every 31 seconds.
The operations stand-by time is set on the larger plate on the left
side-wall of the electrical cabinet.
The operations stand-by time is set in the factory to a minimum
time of 2 minutes and can be increased to a maximum time of 8
minutes.
