This guideline provides information on the
recommended service intervals. The recommen-
dation is based upon good engineering practice
and on experience gained from operation even
under extreme conditions.
Danfoss APP pumps are designed for long
operation and low maintenance and life cycle
costs.
Provided that the pump has been running
according to the Danfoss speci cations, Danfoss
guarantees one year service-free operation,
however, max. 18 months from date of
production. After one year of operation it is
recommended to inspect the pump and replace
worn parts, if any.
