8.3. Logging

Maintenance documentation with the following
information is to be kept on file:
• Date of the maintenance
• What was maintenance performed on?
• Was anything conspicuous? Remarks!
• What was replaced?
• Ampere measurement of each pump with clamp-
on ammeter shortly before the end of the deacti-
vation point of the pump (detection of wear).
• Name of the maintenance personnel and signa-
ture of the responsible individual.
This verification can be used as the basis for guar-
antee claims and must be handled with care.

8.4. Maintenance intervals

To ensure reliable operation, various maintenance
tasks must be carried out regularly.
A log must be kept of all maintenance and repair
work, which must be signed by the service em-
ployee and the end-user.
NOTE
We recommend concluding a maintenance
contract for regular maintenance work. Please
contact Wilo customer service for more infor-
mation about this.
