Note
Notes or instructions that make the job
easier and ensure safe operation.
Caution
If away for a long period (e.g. holidays) we
recommend that you turn off the water
supply to the toilet served by the lifting
station.
Note
This is a domestic unit.
Toilets connected to this unit can be used
like any normal toilet, and require
minimum maintenance. The unit will
operate automatically as soon as the
required level of water enters the tank.
Caution
Only the disposal of toilet paper, faecal
matter and wastewater will be covered by
warranty. Any damage due to foreign
bodies such as cotton, condoms, sanitary
towels, wet wipes, food, hair, metal, wood
or plastic objects, will not be covered by
the warranty. Solvents, acids and other
chemicals can also cause damage to the
unit, and will invalidate the warranty.
Note
Applications according to EN 12050-3.
Not for public use, only limited number of
users.
Installation with direct connection to toilet
and in the same room as sanitary
appliances.
A second toilet must be available above
the backflow level.
The product must be fastened to the floor
to prevent uplift and turning.

4. Pumped liquids
Domestic wastewater and sewage containing toilet
paper and faeces.
Ordinary liquids for cleaning of the appliances
connected. pH value: 4-10.

number: 97772315.
Fig. 1 Alarm device
6. Electrical connection
Make sure that the product is suitable for the supply
voltage and frequency available at the installation
site.
The electrical connection must be carried out in
accordance with local regulations.
The thermal switch cuts out the motor in case of
overtemperature and cuts it in again automatically
after cooling.
Caution
The product must not pump harsh
chemicals or solvents. See the quick
guide.
The product is designed for flush volumes
of 4, 6 and 9 litres. A 4-litre flush is
permissible only if the amount of solids in
the pumped liquid is small.
Caution
Do not pull or lift the product by the power
supply cable.
Note
The product must be accessible for
maintenance and repair.
If the product is installed behind the wall, a
service hatch of sufficient size is
necessary.
The product must be placed in a frost-free
room to prevent the pumped liquid from
freezing.
Make sure that all external pipework is
adequately insulated.
The discharge pipe must be made of rigid
material, such as copper, or of rigid PVC
with solvent-welded joints.
To prevent the transmission of vibrations
to buildings, make sure that the pipework
is thoroughly fixed and that fittings cannot
move and are not in contact with building
parts.
TM04 9469 4310
Warning
The product must be earthed. The
protective earth of the socket outlet must
be connected to the protective earth of the
pump. The plug must therefore have the
same PE connection system as that of the
socket outlet. If not, use a suitable
adapter.
The installation must include an earth
leakage circuit breaker for protection
against earth fault currents. This will
ensure protection when using a Schuko
plug or another plug with earth pin.
Warning
The product must be connected to a mains
switch with a minimum contact gap of 3
mm in all poles.

7. Service
For service kits, see www.productselection.grundfos.com.
7.1 Service documentation
Service documentation is available at www.productselection.grundfos.com.
If you have any questions, please contact the
nearest Grundfos company or service workshop.
7.2 Maintenance
The lifting station does not require any special
maintenance, but we recommend that you check
operation and pipe connections at least once a year.
Change the carbon filter once a year. See section
7.4 Service instructions.
7.3 Adjustment of run time
The default setting ensures proper operation in most
pipework. If the pipework is particularly long or short,
it may be necessary to adjust the run time.
For a guide to adjusting the run time, see
www.product-selection.grundfos.com.

9. Fault finding
See also section 7.4 Service instructions.
Warning
Remove the fuse, pull out the plug, or
switch off the power supply.
Make sure that the power supply cannot
be accidentally switched on.
All rotating parts must have stopped
moving.
The product must only be serviced by
trained service staff.
Fault Cause Remedy
1. Motor does not start
when the level in the
tank reaches the start
level.
a) Supply failure. Reestablish the power supply.
b) Fuse blown.
If new fuse blows at once,
either cable or motor is faulty.
Replace the fuse.
Measure cable and motor. If cable or
motor is defective, replace the defective
parts.
c) Impeller/grinder stuck. Thermal
switch tripped.
Free the impeller/grinder, and wait until
the motor is cooled down and the
thermal switch has reset.
d) Pressure switch pipe blocked. Remove the pressure switch and clean
the pipe.
2. Motor hums but does
not operate.
a) Impeller/grinder stuck. Free the impeller/grinder and check that
it can rotate freely.
b) Motor or capacitor defective. Replace the motor or capacitor.
c) Control board defective. Replace the control board.
3. Motor runs
continuously or at
irregular intervals.
a) Water leaking from inlet into
tank.
Check for leaking appliances.
b) Water leaking back into tank
from discharge pipe.
Check the non-return flap.
c) Pressure switch defective. Replace the pressure switch unit.
4. Motor runs but does
not evacuate water.
a) Pump or tank blocked. Remove blockage.
b) Air lock in pump or vent hole in
pump housing blocked.
Check operation of vent valve in the
tank.
Check that the carbon filter is not wet.
Check that the vent hole in the pump
housing is not blocked.
c) Discharge port or pipe blocked. Remove blockage.
Check the non-return flap.
5. The lifting station
evacuates slowly.
a) Discharge pipe is too long or
has an excessive number of
bends.
Increase the discharge pipe size.
Change pipework to reduce number of
bends.
Change bends to soft bends.
b) The pump housing is leaky. Replace the pump housing (service
part).
c) Hydraulics or grinder blocked. Check and clean the hydraulics and
grinder.
6. Rattling noise from the
lifting station, but
water is evacuated.
a) Foreign body hitting the
impeller/grinder.
