voltage and frequency available at the installation

site.

The electrical connection must be carried out in

accordance with local regulations.

The electrical connection should be made according

the table below.

7. Service

For service kits, see www.product-

selection.grundfos.com.

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 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.

The product must be connected to a mains

switch with a minimum contact gap of 3

mm in all poles.

In case of overtemperature, a thermal

switch cuts out the motor and cuts it in

automatically when it has cooled

sufficiently.

7.1 Service documentation

Service documentation is available at 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 7.4 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.

7.4 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/grinder stuck

1.1 Disconnect the power supply.

1.2 Unscrew the plug in the cover.

1.3 Insert a screwdriver (min. 110 mm) through the

plug hole and into the slot of the shaft end.

Turn the shaft right and left to free the impeller/

grinder from dirt.

1.4 Fit the plug, and switch on the power supply to

check if the impeller/grinder 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 toilet and tank by means of a power drill.

Pressure switch pipe blocked

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

(accessory).

3.2 Unscrew the cover.

3.3 Pull out the complete pressure switch.

3.4 Check and clean the pressure switch pipe.

Foreign body in tank

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 (accessory).

Unscrew the cover. See 3.2.

4.1 Remove the four screws of the motor flange.

4.2 Lift the motor flange to reduce the compression

of the O-ring. Insert a screwdriver into the notch

underneath the supply cable and press it down.

4.3 Lift out the complete motor-pump unit by the

handles.

4.4 Check and clean the tank and impeller/grinder.

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 personnel.

Note

The pressure switch unit can be removed

separately.

Caution

Make sure that the little tube in the top of

the pipe did not become blocked when you

cleaned the pipe!

Note

Lubricate the sealing area of the pressure

switch for easier fitting.

Note

Lift the unit vertically before tilting it!

Warning

Beware of the sharp edges on the grinder.

Wear protective gloves.

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 7.4 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 personnel.

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 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.

Remove the foreign body.

7. Odour from the tank. a) Carbon filter contaminated. Replace the carbon filter.

English (GB)

10. Disposal

This product or parts of it must be disposed of in an

environmentally sound way:

Grundfos company or service workshop.

Subject to alterations.

8. Water from shower or

another appliance

connected to the lower

inlets drains off slowly.

Backflow from the

lifting station.

a) Non-return flap in inlet stuck,

does not open or does not close

sufficiently.

Check the non-return flap.

b) Hydraulics or grinder blocked. Check and clean the hydraulics and

grinder.
