5. Installation

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.

English (GB)

10. Disposal

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

environmentally sound way:

1. Use the public or private waste collection service.

2. If this is not possible, contact the nearest

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) 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.
