8.4 Service
All the spare parts used in repairs must be
original ones and the accessories must be
approved by the manufacturer so as to be able
to guarantee maximum safety of the machines
and systems in which they may be fitted.
If Grundfos is requested to service the pump,
Grundfos must be contacted with details about
the pumped liquid, etc. before the pump is
returned for service. Otherwise Grundfos can
refuse to accept the pump for service.
Possible costs of returning the pump are paid by
the customer.
However, any application for service (no matter
to whom it may be made) must include details
about the pumped liquid if the pump has been
used for liquids which are injurious to health or
toxic.
9. Technical data
Note
Any modification of the pump not
authorized beforehand will relieve
the manufacturer of all
responsibility and void the pump’s
warranty.
Note
If a pump has been used for a liquid
that is injurious to health or toxic,
the pump will be classified as
contaminated.
