Maintenance
The Micropilot M measuring instrument requires no special maintenance.
Exterior cleaning
When cleaning the exterior of measuring devices, always use cleaning agents that do not attack the
surface of the housing and the seals.
Replacing seals
The process seals of the sensors must be replaced periodically, particularly if molded seals (aseptic
construction) are used. The period between changes depends on the frequency of cleaning cycles
and on the temperature of the measured substance and the cleaning temperature.
Repairs
The Hauser repair concept assumes that the measuring devices have a modular design and
that customers are able to undertake repairs themselves. Spare parts are contained in suitable kits.
They contain the related replacement instructions. All the spare parts kits which you can order from
Hauser for repairs to the Micropilot M are listed with their order numbers on and . Please
contact Hauser Service for further information on service and spare parts.

• Repairs to Ex-approved devices may only be carried out by trained personnel or by
Hauser Service.
• Comply with the prevailing standards, national Ex-area regulations, safety instructions (XA) and

Replacement
After a complete Micropilot or electronic module has been replaced, the parameters can be
downloaded into the instrument again via the communication interface. Prerequisite to this is that
the data were uploaded to the PC beforehand using the ToF Tool / Commuwin II.
Measurement can continue without having to carry out a new setup.
• You may have to activate linearisation (see BA 221F on the enclosed CD-ROM)
• You may need to record the tank map again (see Basic Setup)
After an antenna component or electronic has been replaced, a new calibration must be carried out.
This is described in the repair instructions.
