3. General description

Grundfos Multilift MSS lifting stations are supplied complete with

collecting tank, pump, level sensor, LC 220 controller and

connection accessories. Depending on the variant, a non-return

valve is included.

The following gives a description of the components.

Fig. 1 Multilift MSS, front and rear view

3.1 Applications

Grundfos Multilift MSS lifting stations are designed for the

collection and pumping of domestic wastewater with no free flow

to sewer level. Grundfos Multilift MSS lifting stations are designed

for the collection and pumping of the following liquids:

• domestic wastewater

• grey wastewater without faeces

• black water with faeces and discharge from water closets

• sludge-containing water.

The lifting stations are capable of pumping liquids containing

fibres, textiles, faeces, etc., below sewer level from minor

buildings such as private dwellings, flats, holiday homes etc.

Do not pump rainwater with the Multilift MSS lifting stations for

these two reasons:

• The motors of the lifting stations are not designed for

continuous operation which may be necessary in case of

heavy rainfall.

• Rainwater must not be discharged into a lifting station inside a

building according to EN 12056-4.

If in doubt, please contact Grundfos for advice.

Do not discharge the following substances/types of wastewater

via a lifting station:

• solid matter, tar, high content of sand, cement, ash, cardboard,

debris, garbage etc.

• wastewater from sanitary installations situated above the flood

level (this must be drained away via a free flow drainage

system according to EN 12056-1)

• wastewater containing substances such as large amounts of

greasy wastewater from deep fryers or similar appliances.

4. Transportation and storage

For long periods of storage, the LC 220 controller must be

protected against moisture and heat.

After a long period of storage, the pump must be inspected before

it is started up again. Make sure that the impeller can rotate

freely.

5. Product description

The MSS Multilift lifting stations are described in the following

sections:

• section 5.1 Lifting station describing lifting station, collecting

tank, pump, non-return valve and level sensor

• section 5.2 LC 220 controller describing the controller as well

as the functions of the controller.

In section 6. Installation of lifting station and the following

5.1.1 Collecting tank

The gas-, odour- and pressure-tight collecting tank is made of

wastewater resistant polyethylene (PE) and has all necessary

ports for the connection of inlet pipes, outlet pipe, venting pipe

and a manually operated diaphragm pump, which is available as

an accessory.

Thus the collecting tank offers five horizontal inlets from the back

and the sides of the tank (4 x DN 100, 1 x DN 50) and two vertical

inlet connections at the top of the tank (1 x DN 100, 1 x DN 50).

The side and back inlets are 180 and 250 mm above the floor for

connection to direct wall-hung or floor-standing toilet according to

EN 33 and EN 37. Further sanitary appliances can be connected

to the other ports.

The tank volume and effective volume (volume between start and

stop) of the collecting tank appear from the following table:

Setting to the relevant inlet level can be made via a DIP switch on

the control panel of the controller. See section 7.4 Setting of LC

220.

The factory-set inlet level is 250 mm above the floor.

To minimise sedimentation, the tank bottom is chamfered to lead

the wastewater to the pump.

5.1.2 Pump

The pump impeller is designed as a free-flow vortex impeller,

ensuring almost unchanged performance throughout the entire

life of the pump.All parts in contact with the pumped liquid are

made of stainless steel. The pump has a mechanical shaft seal.

See more technical data in section 11. Technical data.

Single-phase motors have run capacitors.

Single- and three-phase motors are protected by a thermal switch

in the windings and an additional thermal circuit breaker to cut out

the motor in case of overload.

Three-phase motors:

If the phase sequence is wrong, the controller indicates fault and

prevents the pump from starting. For correction of phase

sequence, see section 5.2.2 Control elements and indicator lights

and fig. 8.

5.1.3 Non-return valve

The DN 80 non-return valve includes a drain screw to lift up the

internal flap in order to drain the outlet pipe in case of

maintenance or service. The valve is designed and tested

according to EN 12050-4. See fig. 4.

Fig. 4 Non-return valve

5.1.4 Level sensor

The piezoresistive pressure sensor placed in the controller is

connected via a hose to a pressure tube in the tank. The screw

cap where the hose is connected includes a connection for a DN

100 tube. This tube, the pressure tube, extends down into the

tank. The rising liquid level compresses the air inside the

pressure tube and hose, and the piezoresistive sensor transforms

the changing pressure into an analogue signal. The control box

uses the analogue signal to start and stop the pump and to

indicate high water-level alarm. The pressure tube is fixed

underneath the screw cap and can be taken out for maintenance,

service and for cleaning the inside of the tube. An O-ring ensures

tightness.

The hose is supplied in lengths of 4 or 10 m. The hose must be

connected to the controller.

5.2 LC 220 controller

The level controller switches the MSS Multilift pump on and off

according to the liquid level measured by the piezoresistive,

analogue level sensor. When the start level is reached, the pump

will start, and when the liquid level has been lowered to the stop

level, the pump will be stopped by the controller. An alarm will be

indicated in case of high water level in the tank, sensor failure

etc.

Fig. 6 LC 220 level controller for Multilift MSS

The LC 220 controller has the following functions:

• on/off control of one wastewater pump based on a continuous

signal from a piezoresistive, analogue level sensor

• automatic test runs during long periods of inactivity (24 hours

after last operation)

• battery backup in case of mains supply failure (accessory)

• selection of automatic alarm resetting (via DIP switch)

• selection between two inlet levels (via DIP switch)

• operating indication of:

- power on

- pump running

- time for service/maintenance (selectable via DIP switch).

• alarm indication of:

- too high liquid level, which triggers a high-level alarm

- wrong phase or phase sequence detection for three-phase

pumps

- sensor failure

- external level alarm

- runtime monitoring.

As standard, the LC 220 controller has one alarm signal output

for common alarm and three signal inputs for connecting the

piezoresistive sensor, an additional float switch functioning as

backup for the analogue sensors and an additional level switch

for flood detection outside the Multilift MSS. Lifting stations are

often installed in a sump inside the basement - the lowest point in

the building. In case of e.g. groundwater inflow or water pipe

burst, an alarm will be indicated by the controller. If the liquid

level in the sump rises above the high-level alarm level, the

corresponding alarm LED will be on and the built-in buzzer will be

activated.

A battery (accessory) can be installed to activate an acoustic

alarm (buzzer). The buzzer will be activated as long as the fault

exists as it cannot be reset.

In case of power failure, the common alarm output, which is a

potential-free changeover contact, can forward the alarm signal

to a control room by means of an external power source.

A PC Tool can be connected in order to implement updates and

further adjustments.

Furthermore, a log of the last 20 faults can be read out, as well as

the number of starts and operating hours (accessory).

Type key, LC 220 controller

Nameplate, LC 220 controller

The actual controller type, voltage variant, etc., are stated in the

type designation on the nameplate situated on the side of the

controller cabinet.

Fig. 7 Example of an LC 220 nameplate

5.2.1 Design

The LC 220 level controller incorporates the necessary

components such as relays and a control panel with indicator

lights for indication of operating conditions and fault indications.

Furthermore, it has a level input which is activated directly via the

pressure tube inside the collecting tank. Finally, it has terminals

for power supply, connection to the pump and an alarm signal

output for common alarm.

The front cover is closed by four bayonet fastenings with quarter

turn locks. On the left side, the locks are extended and connected

to the cabinet bottom with hinge strings.

6.2 Guidelines for installation of lifting station

Guidelines for correct mechanical installation of lifting

station according to EN 12056-4

See section 6.1.1 Installation sketch.

• Install the lifting station in a properly lit and vented room with

60 cm free space around all parts to be serviced and operated.

• Provide a pump sump below the floor level. If a lifting station is

installed in a basement with the risk of penetrating

groundwater, it is advisable (in certain countries required) to

install a drainage pump in a separate pump sump below floor

level in order to drain the room. See fig. 10.

• All pipe connections must be flexible to reduce resonance.

• Lifting stations must be secured against uplift and twist.

• All outlet pipes (lifting station, diaphragm pump and drainage

pump) must have a loop above the local backwater level. The

highest point of the goose neck/reversed water seal must be

above street level.

• For outlet pipes, DN 80 and upwards, install an isolating valve

in the outlet pipe. Also provide an isolating valve in the inlet

line.

• Surface water must not be discharged into the lifting station

inside the building. It must have its own pumping station

outside the building.

• Lifting stations must be provided with an approved non-return

valve according to EN 12050-4.

• The volume of the outlet pipe above the non-return-valve up to

the backwater level must be smaller than the effective tank

volume.

• In general, a lifting station for black wastewater must be

vented above roof level. However, it is permitted to lead the

ventilation, as a secondary ventilation, into the main building

ventilation system.

• If the wastewater is discharged into a collecting line, this

collecting line must have a filling ratio of at least h/d = 0.7.

The collecting line must be at least one nominal diameter

bigger after the outlet pipe connection.

• Use a diaphragm pump for simple, manual draining of the

collecting tank in case of pump failure (not obligatory).

6.3 Recommended steps for mechanical installation of

lifting station

1. Checking the scope of delivery. For scope of delivery, see

section 2. Scope of delivery.

2. Preparing the inlets by cutting out the required holes. Use cup

drills ∅100 for DN 100 and ∅43 for DN 50 inlets. The cutting

line is recessed. To avoid sharp cutting edges, the holes must

be deburred. The socket seals are provided with collars.

3. Preparing the connection for diaphragm pump (optional). Use

cup drill, ∅43, for DN 50 connection socket. To avoid sharp

cutting edges, the hole must be deburred.

Fig. 11 Cutting or drilling of connection holes

4. Connecting the inlet pipe to the tank. Install an isolating valve

between inlet pipe and lifting station to avoid inflow during

maintenance and service. We recommend an easy-to-handle

PVC isolating valve.

Fig. 12 Installation of isolating valve

Note

The collecting tank, pump and cables may be flooded

(max. 2 m for 7 days).

Caution

The controller must be installed in a dry and well

ventilated place.

TM05 1242 2511

TM03 3614 0406

Caution

Make sure that weight from inlet, outlet and vent

pipes does not rest on the tank. Long pipe sections,

valves, etc. must be supported.

Warning

Never step on the lifting station.

5. Connecting the outlet pipe.

Install an isolating valve between the non-return valve and the

supplied flexible connection hose, DN 100 (internal diameter

110 mm). A flexible connection can be ensured if a distance of

approx. 5 cm is left between the pipe ends of the inlet, outlet

and vent pipes and the ports of the lifting station.

Fig. 13 Isolating valve on top of non-return valve

6. Connecting the venting pipe.

The DN 50 vent port on top of the tank is open. Connect the

venting pipe to the vent port via a flexible connection piece.

The venting pipe must be led out above the roof into the open

air in accordance with local regulations. A flexible connection

can be ensured if a distance of approx. 3 cm is left between

the venting pipe end and the vent port.

7. Connecting the diaphragm pump (optional).

Fit the diaphragm pump on the outlet side. To facilitate

servicing of the diaphragm pump, we recommend fitting a 1

1/2" isolating valve to the tank port.

8. Fixing the tank to the floor.

9. Maintenance and service

The Multilift MSS requires a minimum of maintenance.

According to EN 12056-4, lifting stations in single-family houses

must be checked once a year. During the check, local regulations

must be observed.

The periodic checks of the lifting station must be carried out by

authorised personnel and must comprise electrical and

mechanical maintenance.

Check the following points:

• Outlet and inlet connections

Check all connections to the lifting station for tightness and

leakages. Make sure that weight from the inlet, outlet and

venting pipes does not rest on the tank. Long pipe sections,

valves, etc. must be supported.

• Power consumption

See nameplate.

• Cable entry

Make sure that the cable entry is watertight and that the

cables are not bent sharply and/or pinched.

• Pump parts

Check that the vent hole of the pump housing is clear by

dismantling the pump from the support flange.

We recommend replacing the O-ring sealing between pump

and support flange.

Make a test run with clean water. In case of noise, vibration or

abnormal running, contact Grundfos.

• Shaft seal

Check the shaft seal, O-ring and oil. The oil chamber contains

60 ml non-poisonous oil. Used oil must be disposed of in

accordance with local regulations. This work must be carried

out by the manufacturer or an authorised service workshop.

See service instructions.

Cleaning the non-return valve (if required)

Proceed as follows:

1. Close the isolating valves in the outlet pipe and in the inlet

pipe (if fitted) or drain the outlet pipe by tightening the drain

screw on the side of the non-return valve.

See section 5.1.3 Non-return valve.

2. Clean the non-return valve via its inspection cover.

Replace the gasket of the inspection cover when

reassembling the non-return valve.

9.1 Electrical maintenance

• Check the gaskets of the LC 220 cabinet front cover and of the

cable entries.

• Check the cable connections.

• Check the controller functions.

• Check and clean the pressure tube. See section 9.2 Cleaning

the level sensor.

• If LC 220 is installed in a particularly moist environment in a

basement, we recommend checking the terminals on the PCB

in order to identify possible corrosion. In typical installations,

the contacts will work for many years and do not require any

inspection.

• Replace the 9 V battery, if fitted, in connection with annual

service.

9.2 Cleaning the level sensor

1. Push the ON-OFF-AUTO selector switch to position OFF ( ).

See section 5.2.2 Control elements and indicator lights.

2. Loosen the screw cap by turning it counterclockwise.

See fig. 19.

3. Lift the pressure tube carefully out of the collecting tank.

Do not lift it by means of the hose.

4. Check for possible deposits on or in the pressure tube. See

section 5.1.4 Level sensor.

5. Scrape off any deposits. If necessary, remove the hose from

the controller and rinse the tube and hose with clean water at

low pressure. Make sure no water remains in the hose.

6. Refit the pressure tube by screwing the screw cap on to the

tank. Reconnect the hose to the controller.

7. Check the sensor by test running Multilift MSS.

Fig. 19 Removing the pressure tube

9.3 Contaminated lifting station or components

If Grundfos is requested to service the lifting station, Grundfos

must be contacted with details about the pumped liquid, etc.

before the lifting station is returned for service. Otherwise

Grundfos can refuse to accept the lifting station for service.

Lifting stations which have been in contact with the pumped liquid

must be thoroughly cleaned before they are returned to Grundfos.

Any costs of returning the lifting station are to be paid by the

customer.

However, any application for service (no matter to whom it may

be made) must include details about the pumped liquid if the

lifting station has been used for liquids which are injurious to

health or toxic.

Warning

Before carrying out maintenance and service on

lifting stations used for pumping liquids which might

be hazardous to health, make sure that the lifting

station has been thoroughly flushed with clean water

and that the outlet pipe has been drained. Rinse the

parts in water after dismantling. Make sure that the

isolating valves have been closed. The work must be

carried out in accordance with local regulations.

Warning

Before making any connections in LC 220 or working

on lifting stations, make sure that the power supply

has been switched off and that it cannot be

accidentally switched on.

Note

Do not loosen the support flange. It is screwed and

sealed to the collecting tank. Loosen the four

stainless steel clamps instead.

Note

The above list is not complete. LC 220 may be

installed in environments which require thorough and

frequent maintenance.

TM05 0545 1011

Warning

10. Fault finding

Warning

Before carrying out any work on lifting stations used for pumping liquids which might be hazardous to health, make sure that

the lifting station has been thoroughly flushed with clean water and that the outlet pipe has been drained. Rinse the parts in

water after dismantling. Make sure that the isolating valves have been closed.

The work must be carried out in accordance with local regulations.

Before making any connections in LC 220 or working on lifting stations, etc., make sure that the power supply has been

switched off and that it cannot be accidentally switched on.

Fault Cause Remedy

1. The pump does not run. a) No power supply.

Without battery backup:

None of the indicator lights are on.

With battery backup:

See section 5.2 LC 220 controller.

Switch on the power supply.

b) The ON-OFF-AUTO selector switch is in

position OFF ( ). See section 5.2.2 Control

elements and indicator lights.

Push the ON-OFF-AUTO selector switch into position

ON ( ) or AUTO ( ).

c) Control circuit fuses are blown. Check and eliminate the cause. Replace the control

circuit fuses.

d) The thermal switch has cut out the pump. Allow the pump to cool. After cooling, the pump will

restart automatically unless LC 220 has been set to

manual restarting (see section 7.4 Setting of LC 220).

If so, push the ON-OFF-AUTO selector switch into

position OFF ( ) for a short period.

e) Motor/supply cable is defective. Check and replace motor and cable, if necessary.

f) The power circuit board or the LED board is

defective.

Replace the power circuit board or LED board.

g) The new DIP-switch setting does not work

correctly.

Switch off the power supply to the controller for 1 minute

and switch it on again (normal procedure). See section

7.4 Setting of LC 220.

2. The sensor signal is out

of range.

All pumps are started

and high-level alarm is

on.

a) Not all outlet valves are open. Open all outlet valves.

b) There is a blockage in the tank or pump. Remove the blockage.

c) The pump is not vented correctly. The pump

cannot build up pressure.

Remove any blockage from the vent hole underneath

the pump.

d) The lifting station is undersized. Recalculate the inflow parameters and compare the

result with the tank volume and pump performance. If

you need a new product, contact the nearest Grundfos

sales company.

3. The pump starts and

stops too frequently

even if there is no

inflow.

a) The level sensor is blocked. Clean the level sensor (see section 9.2 Cleaning the

level sensor).

b) The ventilation of the inner pump housing is

blocked and the pump cannot build up

pressure.

Check the pump housing and remove any impurities.

4. The pump starts

sometimes without

visible reason.

a) Test run 24 hours after last operation. No action necessary. It is a safety function that prevents

the shaft seal from seizing up.
