The pumps are designed for intermittent operation
(S3). When completely submerged, the pumps can
also operate continuously (S1).
Installation depth
Maximum 10 m below liquid level.
Operating pressure
Maximum 6 bar.
Number of starts per hour
Maximum 30.
pH value
Pumps in permanent installations can be used for
pumping liquids with a pH value between 4 and 10.
Liquid temperature
0-40 °C.
For short periods (maximum 10 minutes), a
temperature of up to 60 °C is permissible. This
applies for standard versions only.
Density of pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than that of water, use
motors with correspondingly higher outputs.
Sound pressure level
The sound pressure level of the pumps is lower than
the limiting values stated in the EC Council Directive
2006/42/EC relating to machinery.
This appliance can be
used by children aged
from 8 years and above
and persons with
reduced physical,
sensory or mental
capabilities or lack of

Lifting the product
CAUTION
Crushing of hands
Minor or moderate
personal injury
- Do not put your hands
or any tool into the
pump inlet or outlet
port after the pump has

must be carried out by
specially trained
persons.
Work in or near pits must
be carried out according
to local regulations.
WARNING

Mechanical installation
WARNING
Crushing hazard
Death or serious
personal injury
- Make sure that the
hook is fixed properly
to the lifting bracket.
- Always lift the pump by
its lifting bracket or by
means of a forklift truck
if the pump is fixed on
a pallet.
- Never lift the pump by
means of the power
cable, hose or pipe.
- Make sure that the
lifting bracket is
tightened before
attempting to lift the
pump. Tighten if
necessary.
DANGER
Electric shock
Death or serious
personal injury
- Before beginning the
installation, switch off
the power supply and
lock the main switch in
position 0.
- Switch off any external
voltage connected to
the product before
working on it.
CAUTION
Hot surface
Death or serious
personal injury
- Make sure that the
pump has cooled down
before touching it.
DANGER
Electric shock
Death or serious
personal injury
- Before installing the
pump and starting it up
for the first time, check
the power cable for
visible defects to avoid
short circuits.
English (GB)

CAUTION
Biological hazard
Minor or moderate
personal injury
- Flush the pump
thoroughly with clean
water and rinse the
pump parts in water
after dismantling.
Pits for submersible
sewage and
wastewater pumps
may contain sewage or
wastewater with toxic
and/or disease-causing
substances.
- Wear appropriate
personal protective
equipment and
clothing.
- Observe the local
hygiene regulations in
force.
Before beginning installation procedures,
make sure that the atmosphere in the pit is
not potentially explosive.
Make sure the pit bottom
is even before installing
the product.
Always use Grundfos
accessories to avoid
malfunctions due to
incorrect installation.
Only use the lifting
bracket for lifting the
pump. Do not use it to
hold the pump when in
operation.
Make sure that the liquid
entering the pit through
the inlet does not cause
water to be splashed on
the sensors of the pump.
Make sure that the pipes
are installed without the
use of undue force. No
loads from the weight of
the pipes must be
carried by the pump.
English (GB)
7
Electrical connection
Do not use elastic
elements or bellows in
the pipes. Never use
these elements as a
means to align the
pipes.
When the pump has
reached the
auto-coupling base unit,
shake the pump by
means of the chain to
make sure that it is
placed in the correct
position.
The free end of the cable
must not be submerged
as water may penetrate
through the cable into
the motor.
If several pumps are
installed in the same pit,
the pumps must be
installed at the same
level in order to allow
optimum pump
alternation.
DANGER
Electric shock
Death or serious
personal injury
- Connect the pump to
an external main
switch which ensures
all-pole disconnection
with a contact
separation according
to EN 60204-1, 5.3.2.
- It must be possible to
lock the main switch in
position 0. Type and
requirements as
specified in
EN 60204-1, 5.3.2.
The classification of the installation site
must be approved according to local rules
in each individual case.
The CIU unit, if used, must not be installed
in potentially explosive environments.
On explosion-proof pumps, make sure that
an external earth conductor is connected
to the external earth terminal of the pump
using a conductor with a secure cable
clamp. Clean the surface of the external
earth connection, and fit the cable clamp.
The cross section of the earth conductor
must be at least 4 mm2, e.g. type H07
V2-K (PVT 90 °) yellow and green.
Make sure that the earth connection is
protected from corrosion.

person.
DANGER
Electric shock
Death or serious
personal injury
- Before installing the
pump and starting it up
for the first time, check

Do not run the pump via
a frequency converter.
Make sure there are at
least 3 m free cable
above the maximum
liquid level.
Set the motor-protective
circuit breaker to the
maximum current of the
pump. The maximum
current is stated on the
pump nameplate.
Make sure that the pump
is connected in
accordance with the
instructions given in this
booklet.
