Maintenance / cleaning / change of medium
• After removal of the unit from the tank for maintenance and
cleaning purposes please note: When remounting, the unit must be
mounted exactly in the same position and at the same installation
height as before. Before removal, fix the set installation height with
the supplied stainless steel tube clip (→ page 30).
• If the connection between the sensor and the tank ground is
changed, another OP adjustment must be carried out (→ page 35).
• After a change of media with dielectric constants which differ
greatly (e.g. oil / water) the unit must be adjusted to the new medi-
um and another adjustment must be carried out (→ page 33,
MEDI / page 35, cOP).
• Keep the probe free from deposits, especially the area of the over-
flow protection (OP segment). Deposits in this area can lead to an
incorrect response of the overflow protection.
