NOTE
Do not install the pump stations underfloor in areas which are subject to a risk of
pressing groundwater.
1. Excavate a sump.
2. Cover the floor of the sump with a 15 cm layer of fine sand. Compact the sand
layer.
3. Position the completely assembled pump station in the sump.
4. Connect the discharge line, inlet line and vent line.

Damage to the machinery!
▷
Prior to commissioning a pump station which has been supplied completely
assembled, always remove the transport lock of the pump.
NOTE
Prior to burying the pump station, make sure that all preparatory and connection
work at pump and piping has been completed.
NOTE
KSB recommends connecting the piping with commercially available "System J"
spigot and socket connections. This system allows for PVC sockets to be fitted and
glued in.

Guide the power cable(s) through the vent nozzle. Do not alter the original
condition of the cable grommet seat. Do not drill any holes for the PG cable glands.
