Waste water lifting system AH-300
The device has a collecting basin with an inlet connection for a DN 20 and DN 25 hose. The equipment also includes a level-controlled pump with filter cage, as well as a non-return valve and a 6 m long DN 12 outlet hose. The overflow warning is guaranteed: A level switch with voltage-free changeover contact signals faults. The AH-300 wastewater lifting system is suitable for continuous operation.
The condensed water flows into the collecting basin of the wastewater lifting system and is pumped to the drain by the level-controlled delivery pump. The delivery pump switches on at a level of approx. 80 mm and switches off again at approx. 55 mm. The integrated filter cage protects the pump from coarser impurities. The non-return valve prevents backflow into the collecting basin when the pump is switched off.
A second overflow warning switch with voltage-free changeover contact can be used for external fault messages or to switch off the heat generator. The overflow warning switch switches on at a level of approx. 120 mm and is switched off again at approx. 95 mm. The optional alarm delay (see accessories) for connection to the overflow warning switch enables the heat generator to be switched off in parallel with the fault signal, or with a time delay.
