3. Product introduction

Grundfos Liftaway B 40-1 for underfloor installation
is a compact mini lifting station consisting of a tank
and a wastewater pump, type Unilift KP 150, Unilift
KP 250 or Unilift AP12, with level switch for
automatic start/stop. The lifting station is designed
for the pumping of wastewater from wash basins,
washing machines, showers and floor drains. The
Liftaway B 40-1 can also be used for the collection
and pumping of rain water.
The variable height of the tank, which is installed
under the floor, makes it easy to adjust the tank to
floor level.
These instructions apply to the Liftaway B
40-1 tank and installation kit only.
See also the installation and operating
instructions supplied with the pump.

3.1 Applications

The Liftaway B 40-1 in combination with the Unilift
KP 150, Unilift KP 250 or Unilift AP12 is designed for
