Lifting unit failure

If a failure occurs, the lifting unit can operate in emergency operation. The lifting unit can continue operating as a single-pump system.

Follow these points if the system is working in emergency operation:

• Close the inlet to the related solids separation tank and switch off the failed pump through the switchgear.
• Make sure to follow the operating mode of the active pump.
• The collection tank continues to be filled in emergency operation. If the pump is dismantled, the sewage is pressed out of the collection tank through the connection port.
• A maintenance kit is available for emergency operation. Make sure to mount the blanking covers immediately after the pumping procedure.
• When necessary, open the cover of the supply box/distributor, use a self-priming pump to drain the sewage in the collection tank.
• The solids stay in the solids separation tank. Make sure to dispose of these solids when the solids separation tank is opened.
