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.
Electrical connection with plug/ socket
Initial startup
The device is set in the factory as a natural gas device to gas
type G 20 and as LPG device to G 31. While switching over nat-
ural gas devices to G 25 or other natural gases (see type plate)
or the LPG device to G 30 or other LPGs (see type plate), the
natural gas exhaust values in case of natural gas devices and
the LPG exhaust values in case of LPG devices are to be set ac-
cording to the service information.
The enclosed empty type plate will be filled up with values of the
new gas type that is set and will be fixed on the right side of the
device in the address field. At the same time, the plate with the
G 20 (natural gas device) details or G 31 (LPG device) details
fitted at the factory must be removed.
