Subject to change without notice
5.2.2 Cleaning the sender/receiver unit
Clean the outside of the sender/receiver unit after it has been removed. Inspect the probe
tube and transducers for signs of corrosion, and replace them if necessary. Dust deposits
and caked dust can generally be removed without disassembling the transducer.
Reinstall the sender/receiver unit after completing the work.
The work required for possible replacement of parts (probe tube, transducers) is listed in
the Service Manual.
NOTICE:
The transducer must be cleaned with extreme care. Do not damage the trans-
ducer diaphragm.
Depending on system conditions, the probe tube and transducers may initially
require maintenance more frequently (approx. every 2 weeks, or less if
necessary). If contamination is limited, the cleaning intervals can be gradually
extended to max. 6 months.
