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.

before it is returned for service. Otherwise,

the warranty will be void.

English (GB)

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.

Product number: 98059587.

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.
