The Grundfos CONLIFT1 LS (98452219) is an automatic condensate removal pump for condensing boilers, air conditioning units, dehumidifiers and refrigeration systems where condensate cannot drain away by gravity. It collects condensate in its tank, then lifts it up to 5.5 m to a drain.
As the entry-level model in the CONLIFT range, it keeps the proven components of the CONLIFT1: a built-in syphon water lock that stops boiler gases entering the tank, a pre-installed non-return valve, and a 5 m drain hose in the box. The wired alarm contact can stop the condensate source if the water level rises too high.

Effective tank volume
5 m
PVC drain hose included
Boiler PRV discharge compatible
All CONLIFT models can handle 90 °C inflows for up to 5 minutes and are tested and confirmed suitable for connection to the discharge from the pressure relief valve of a domestic condensing boiler (under 40 kW).
Check before you order
The pump handles condensate that does not need neutralisation, and condensate must run freely into the tank by natural fall. Media temperature is 50 °C continuous. The unit is rated IP20, so install it indoors and keep it dry. Confirm your appliance's condensate requirements before fitting.
Safety
Work on gas appliances must be carried out by a Gas Safe registered engineer. Isolate the electrical supply before any work on the pump. Wire the alarm contact to stop the condensate source, so a fault does not cause an overflow.
Key features
Flexible installation
Floor standing or wall hung. The motor and pump can be rotated 180° on the tank, and four symmetrical inlets suit awkward pipe runs.
Included in the box
A 5 m drain hose and a set of adaptors are supplied, and the discharge accepts 8 mm and 10 mm hoses.
Water lock
A syphon inside the tank prevents gas from the boiler entering the room through the condensate line.
Corrosion-free design
A unique sealing system gives a corrosion-free design, and the motor is rated for up to 60 starts per hour.
Quiet operation
A design focused on low-noise operation at under 47 dB makes it suitable for kitchens, utility rooms and living spaces.
Alarm contact
A wired alarm contact with 1.7 m cable can switch off the condensate source or trigger an external alarm at a high water level.

Frequently asked questions
What does the CONLIFT1 LS do?
It collects condensate from a boiler or cooling appliance in its tank and pumps it automatically to a drain when the tank fills, lifting it up to 5.5 m.
Can it be connected to a condensing boiler PRV discharge?
Yes. All CONLIFT models handle 90 °C inflows for up to 5 minutes and are tested for connection to the discharge from a domestic condensing boiler pressure relief valve under 40 kW.
What is the alarm contact for?
It can switch off the condensate source, or trigger an external alarm, if the water level inside the unit gets too high.
Which hoses does it take?
A 5 m PVC drain hose and adaptors are included. The discharge accepts 8 mm and 10 mm hoses.
Does it need neutralisation?
The pump handles condensate that does not need neutralisation. The CONLIFT1 range is modular, so a neutralisation unit and alarm PCB can be added later if conditions change.
Can I mount it on a wall?
Yes. It can be floor standing or wall hung, and the motor can be rotated 180° on the tank.
