General instructions
5
•Clean the measuring chamber at regular intervals (approx. every 6
months) and, if possible, replace the two seals of the measuring
chamber holder and the sight-glass windows.
•If the water has high iron content, cleaning might be necessary
more often.
•Only use a dry, lint-free cloth for cleaning.
•To carry out maintenance work after the error message “35 Fault
soiling” or “33.Fault optics”, always confirm the error message.
•If maintenance is carried out after an instrument maintenance
message (maintenance interval), maintenance must be confirmed.
BASIC PROGRAM -> SERVICE TIME -> ACKNOWLEDGE
•Wait at least 5 seconds before switching the instrument on and
then off again at the main switch.
•A defective device, regardless of the guarantee period, can be
serviced only when the device is dismantled and the error is de-
scribed. Please also inform us of the indicator type currently in use
and the measured medium. Make no changes or modifications to
the device that go beyond the scope of use specified in these in-
structions. Doing so will void the warranty. This applies particularly
to the measuring chamber, the seal of which must remain undam-
aged. If you send the device in for repair, please completely empty
the measuring chamber and remove the indicator bottle and the
drain funnel. Also remove the power pack and send it back in the
original packaging.
Before dismantling, the type of error must be noted (error number,
error effect, log file of the SD card).
•Once a protective device has been triggered (safety fuse), initially
try resolving the cause of error (e.g. by replacing a defective
valve), before reactivating the protective device. Frequent trigger-
ing always signifies an error, which under certain circumstances
may also damage the device.
•Before sending the device in for maintenance or repair, pack-
age the power pack individually in the original box in which it
was delivered. If the original packaging is no longer available,
package the power pack to prevent breakage.
