NOTICE! Damage caused by leaking sensors
Electrochemical sensors that are faulty or whose expected ser-
vice life is exceeded can leak. The leaking substance can cause
permanent damage to the device.
Faulty sensors can be identified, for example, by the fact that the
corresponding adjustment is no longer possible.
The installation date of the sensor and the expected lifetime can
be found in the
Device information
.
●
Always arrange for SEWERIN Service to replace faulty or leaky
sensors immediately.
