2. Receiving the product
2.1 Transporting the product
3. Installing the product
3.1 Mechanical installation
We strongly recommend that you install an LC A2
alarm device (accessory) if a washing machine,
dishwasher, bathtub and/or a shower are connected
to the lifting station.
The LC A2 will emit an acoustic alarm and switch off
the washing machine or dishwasher if the water level
in the tank becomes too high.
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 pipes are adequately
insulated.
The outlet 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 pipes are thoroughly
fixed and that fittings cannot move and are not in
contact with building parts.
3.2 Electrical connection
Make sure that the product is suitable for the supply
voltage and frequency available at the installation
site.
The thermal switch cuts out the motor in case of
overheating and cuts it in again automatically after
cooling.

5.3 Service instructions
Thanks to the product design, service is easy in case
of malfunction or a blocked pump.
Impeller stuck
1. Disconnect the power supply.
2. Unscrew the cover.
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.
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
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 the tank
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.
2. Unscrew the cover.
3. Remove the four screws of the motor flange.
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.
5. Lift out the complete motor-pump unit by the
handles.
6. Check and clean the impeller, the protecting tube
of the float switch and the tank.
Check that the float switch works properly before
fitting the cover.
Float switch pipe blocked
The float switch unit can be removed separately.
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. See image
3.1 in the appendix.
2. Unscrew the cover.
Turn the bayonet coupling 10 ° clockwise.
Pull out the float switch unit.
Press in the two tabs on the protecting tube.
Pull down the protecting tube.
3. Clean the float switch pipe.
Check that the float switch works properly before
fitting the cover.
4. Lubricate the O-ring seat of the float switch in the
motor flange for easier fitting.
Carbon filter
Replace the carbon filter once a year to ensure
sufficient filter function.
CAUTION
Hot surface
Minor or moderate personal injury
- Wear protective gloves or wait until the
surface of the pump has cooled down.
Lift the unit vertically before tilting it!
Instead of using a carbon filter, Sololift can
also be vented through a venting pipe. In
this case, a venting valve is needed.

6. Fault finding the product
See also section 5.3 Service instructions.
WARNING
Electric shock
Death or serious personal injury
- Before starting any work on the product,
make sure that the power supply has
been switched off and that it cannot be
accidentally switched on.
Fault Cause Remedy
1. The motor does not
start when the level in
the tank reaches the
start level.
a) Supply failure. Reestablish the power supply.
b) A fuse is blown.
If a new fuse blows at once,
either the cable or motor is
faulty.
Replace the fuse.
Measure the cable and motor. If the
cable or motor is defective, replace the
defective parts.
c) The impeller is stuck. The
thermal switch has tripped.
Free the impeller, and wait until the
motor is cooled down and the thermal
switch has reset.
d) The float switch is stuck. Remove the float switch and clean the
pipe.
2. The motor hums but
does not operate.
a) The impeller is stuck. Free the impeller and check that it can
rotate freely.
b) The motor or capacitor is
defective.
Replace the motor or capacitor.
3. The motor runs
continuously or at
irregular intervals.
a) Water is leaking from the inlet
into the tank.
Check for leaking appliances.
b) Water is leaking back into the
tank from the outlet pipe.
Check the non-return flap.
c) The float switch is defective or
stuck.
Clean the float switch unit or replace it,
if necessary.
4. The pump runs but
does not deliver the
rated flow rate.
a) The pump or tank is blocked. Remove the blockage.
b) There is an air pocket in the
pump or the vent hole in the
pump housing is blocked.
Check operation of the 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) The outlet port or pipe is
blocked.
Remove the blockage.
Check the non-return flap.
5. The lifting station
evacuates slowly.
a) The outlet pipe is too long or
has an excessive number of
bends.
Increase the outlet pipe size (maximum
40 mm).
Change pipes to reduce the number of
bends.
Change bends to soft bends.
b) The pump housing is leaky. Replace the pump housing (service
part).
c) The hydraulics are 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) A foreign body is hitting the
impeller.
Remove the foreign body.
7. Odour from the tank. a) The carbon filter is
contaminated.
Replace the carbon filter.
