Why Condensate Removal Matters

Condensate from dehumidifiers, air-conditioning systems, commercial cooling systems, and condensate boilers may seem insignificant. However, in basements below drainage level where these units are typically placed, condensate cannot be removed by natural gravity and may cause damage without a proper lifting station.

The CONLIFT ensures reliable condensate removal as dependable as natural downgrade drainage.

Installation Guidelines

  • Base standing installation
  • Wall-hung installation with easy balancing tools

Inlet Connections:

  • Four symmetric Ø28 mm inlets
  • Flexible positioning for multiple condensate sources

Discharge Configuration:

  • 8 or 10 mm discharge hose
  • Maximum 5 m vertical lift
  • Horizontal runs calculated from sizing table
  • Maintain >1% gradient on horizontal sections
  • Minimum bend radius: Ø60 mm

Electrical Connection:

  • 230 V ±6%, 50 Hz supply
  • Optional alarm contact (250 V / 2.5 A)
  • Auxiliary changeover contact (230 V, 5 A)
