Description
The condensate pump Halm Lift NT25 – with neutralisation – is intended as a compact unit for the delivery of condensate,
produced in gas condensing boilers. The condensate is guided into the integrated – chemically resistant - plastic tank and
fully automatically pumped away.The pump is controlled by an electronic float switch control system with a separate
overflow protection (potential-free relay with load capacity up to 8A ohmic load).

Neutralisation
As per German regulation ATV-A251 neutralisation is compulsory for:
1. liquid drains-out in small waste-water treatments (DIN 4261)
2. land and buildings whose de-watering system does not fulfill the material requirements as per paragraph 5.3 of
regulations
3. buildings, not fulfilling the terms of sufficient dilution, as per paragraph 4.1.1
Please check your country regulations.
Safety equipment
The delivery system is equipped with 2 separately operating float switches. The working float switch activates and
deactivates the pump depending on the level of liquid (with run-on time). The alarm float switch throws over the switch
contact via the potential-free relay. For more details, see the connection example of the potential-free relay.

Lift NT25
We recommend connecting the gas condensing system via the potential-free relay in order to achieve a higher degree of
operating liability, with contactor depending on load.
