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

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.

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.
