With one2clean and oneAdvanced 3-9 PE systems, a certain amount of residual sludge must remain in the
tank after sludge emptying to maintain the purification performance of the wastewater disposal system.
The sludge removal kit ensures that this residual amount of sludge always remains in the tank.
The suction hose for sludge disposal is inserted into the sludge removal pipe down to the bottom. The
opening in the sludge removal pipe above the bottom ensures that the tank cannot be completely emptied.
The additional cover on the sludge removal pipe prevents incorrect use.
