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.
7. Service
For service kits, see www.product-
selection.grundfos.com.
7.1 Service documentation
Service documentation is available on www.product-
selection.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
7.3 Service instructions.
Caution
Do not pull or lift the product by the power
supply cable.
Note
The product must be accessible for
maintenance and repair.
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.
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 ensures
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.
Warning
The product must only be serviced by
trained service staff.
If the power supply cable is damaged, it
must be replaced by the manufacturer, the
manufacturer’s service partner or a
similarly qualified person.
To ensure safe and reliable operation,
always use original spare parts from
Grundfos.
Note
The product must be thoroughly cleaned
before it is returned for service. Otherwise
the warranty will be void.

7.3 Service instructions
Thanks to the product design, service is easy in case
of malfunction or blocked pump.
Digits in the following sections refer to the pictures in
the appendix at the end of this booklet.
Impeller stuck
1.1 Disconnect the power supply.
1.2 Unscrew the cover.
1.3 Turn the motor shaft to the right and left with a
screwdriver inserted into the slot in the shaft end
to free the impeller from dirt.
1.4 Fit the cover, and switch on the power supply to
check if the impeller can rotate freely.
Operation by means of a power drill
2.1 If the product cannot be operated by electrical
power, disconnect the power supply and empty
the tank by means of a power drill.
Foreign body in tank
3.1 If the water level in the tank is above the motor
flange, disconnect the power supply and drain
the tank by means of the drain hose.
3.2 Unscrew the cover.
3.3 Remove the four screws of the motor flange.
3.4 Lift the motor flange to reduce the compression
of the O-ring. Insert a screwdriver into the notch
underneath the power supply cable and press it
down.
3.5 Lift out the complete motor-pump unit by the
handles.
3.6 Check and clean the tank and impeller.
Pressure switch stuck
If the water level in the tank is above the motor
flange, disconnect the power supply and drain the
tank by means of the drain hose. See 3.1.
4.1 Unscrew the cover.
Turn the bayonet coupling 10 ° clockwise.
Pull out the complete pressure switch.
4.2 Check and clean the diaphragm of the pressure
switch.
Carbon filter
5. Replace the carbon filter once a year to ensure
sufficient filter function.
Warning
Before carrying out any service work,
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.
Note
Lift the unit vertically before tilting it!
Note
Check that the pressure switch works
properly (press diaphragm carefully)
before fitting the cover.
Note
The pressure switch unit can be removed
separately.
Note
Check that the pressure switch works
properly (press diaphragm carefully)
before fitting the cover.
Note
Lubricate the O-ring seat of the pressure
switch in the motor flange for easier fitting.
Note
Instead of using a carbon filter, Sololift can
also be vented through a venting pipe. In
this case a venting valve is needed.

9. Fault finding
See also section 7.3 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 stuck. Thermal switch
tripped.
Free the impeller, and wait until the
motor is cooled down and the thermal
switch has reset.
d) Pressure switch stuck. Clean and free the pressure switch.
2. Motor hums but does
not operate.
a) Impeller stuck. Free the impeller and check that it can
rotate freely.
b) Motor or capacitor defective. Replace the motor or capacitor.
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
(maximum 32 mm).
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 blocked. Check that the motor shaft can rotate
freely. Remove the motor flange to clean
the impeller.
6. Rattling noise from the
lifting station, but water
is evacuated.
a) Foreign body hitting the
impeller.
Remove the foreign body.
7. Odour from the tank. a) Carbon filter contaminated. Replace the carbon filter.

Subject to alterations.
8. Water from shower or
another appliance
connected to the lower
inlets drains off slowly.
Backflow from the
lifting station.
a) Hydraulics blocked. Check that the motor shaft can rotate
freely. Remove the motor flange to clean
the impeller.
b) The start level has changed. Check the pressure switch.
c) Inlet pipe diameter is too small. Use a pipe with a larger diameter.
