The unit has full programmable control unit , which will even tell you how many times the unit is cleaning . Auto cut off , when the lid is removed for safety !This has to be one of the best small drums on the market ! We recommend , that when fitting , a flush valve before the unit is added , so that the drain can be flushed , and the screens cleaned twice a year in oase pump cleaning fluid over night .

On this model , water is pumped into  the drum through the  inlet. It is then "sieved " through the drum , and enters the clean chamber, where the cleaning pump is situated. When the drum becomes blocked, the water in the first chamber rises, the sensor in this chamber senses the rise, and starts to revolve the drum, and in turn starts the water pump which delivers water to the jets and cleans the screen of the drum. The waste water is collected inside the drum by a hopper, which then leaves the filter on another 4" pipe. Please note, we recommend that this stays 4" all the way to the drain, if reduced it can become clogged with leaves, blanket weed etc etc. When the drum is clean enough,  the sensor sees this and stops the process. Clean water then leaves this chamber, and enters the bio chamber, where it mixes with Oase hel-x media, that is constantly being moved around via the aerators situated at the bottom of the chamber. Please note an air pump of 40 lpm is required ( not included )
