thespeciedmaintenanceintervals,thepumpor
installation must be checked if strong vibrations
occur during operation.
When used in sewage lifting units inside
buildings or on areas of land, the maintenance
intervals and work shown in DINEN12056‐4
must be adhered to.
8.2.1. Intervals for normal operating conditions

wear
• Functionalinspectionofallsafetyandmonitoring
devices

• Oilchange
15000 operating hours or after 10 years at the
latest
• General overhaul
8.2.2. Intervals for harsh operating conditions
Underharshoperatingconditions,thespecied
maintenance intervals must be shortened accord-
ingly.Inthiscase,contactWilocustomerservice.
Ifusingthepumpunderharshconditions,wealso
recommend signing a maintenance contract.

consumption and the operating voltage in all 3
phases.Innormaloperation,thesevaluesremain
constant.Slightuctuationsdependonthechar-
acteristicsoftheuid.Thecurrentconsumption
