Check electro-mechanical components for wear
Get electro-mechanical components (e.g. contactor combinations) checked for wear by
an electrician. If wear is ascertained, have the affected components replaced by an
electrician or Wilo Customer Service.
General overhaul
During a general overhaul, all of the components, wiring and the housing are checked
for wear. Defective or worn components are replaced.
The switchgear has an integrated maintenance interval indicator. Once the set interval
has expired, "SER" on the main screen blinks. The next interval starts automatically by
resetting the current interval. The function is disabled at the factory.
