not be switched on accidentally.
WARNING
Contamination when pumping drinking
water
Death or serious personal injury
‐Before the pump is used for supplying
drinking water, flush the pump thor-
oughly with clean water.
‐Do not use the pump for drinking water
if the internal parts have been in con-
tact with particles or substances not
suitable for water intended for human
consumption.
The pump must be installed according to
national water regulations and standards.

English (GB)

Position the product horizontally on a solid
support when you work on the product.
Fit a flow sleeve to avoid overheating of
the motor, if you install the pump in one of
these locations:
• in a wide borehole or basin
• horizontally.
3.2.1 Lifting the product
DANGER
Electric shock
Death or serious personal injury
‐Switch off the power supply before you
start any work on the product.
‐Make sure that the power supply can-
not be switched on accidentally.

3.2.2 Cable termination kit
We recommend that you join the submersible drop
cable and the motor cable by means of a Grundfos
cable termination kit, type KM.

3.2.3 Connecting the pipes
WARNING
Pressurised system
Death or serious personal injury
‐Design the system for the maximum
pump pressure plus 10 % to avoid pipe
burst.
We recommend that you install a pressure
relief valve designed for the maximum
pump pressure.
Minimum torque for fitting the first riser
pipe section to the pump is 55 Nm.
1. Fit the riser pipe to the pump. Grip the pump by
the outlet chamber. Take care not to damage the
cables.
a. If you use plastic pipes, use a compression
coupling between the pump and the first pipe
section.
Plastic pipes expand when they are
loaded. Consider this fact in relation
to the installation depth.

English (GB)

3.2.4 Fastening the drop cable to the riser pipe
1. Fit cable clips on the riser pipe for every 3 m.
a. If you use plastic pipes, leave some loose
cable between the cable clips, as plastic pipes
expand when loaded.

3.2.5 Lowering the pump into the borehole
DANGER
Electric shock
Death or serious personal injury
‐Switch off the power supply before you
start any work on the product.
‐Make sure that the power supply can-
not be switched on accidentally.
WARNING
Electric shock
Death or serious personal injury
‐Do not lower the product by the power
cable.
Use appropriate lifting equipment to lower
the pump into the borehole or basin.
Observe local regulations concerning limits
for manual lifting and handling.
We recommend that you secure the pump
with an unloaded straining wire before low-
ering it into the borehole or basin.
1. Note the weight of the product stated on the pump
and motor nameplates.
2. Follow one of these procedures according to the
weight of the product and local regulations:
a. If manual lifting is allowed, grip the pump by
the outlet chamber or attach lifting wires to the
wire hooks.
b. If manual lifting is not allowed, attach lifting
wires to the wire hooks and use appropriate
lifting equipment. Remove the lifting wires
before the product is lowered below ground
level.
3. Lower the pump carefully into the borehole or
basin by holding on to the riser pipe. Take care
not to damage the power cable and the
submersible drop cable.
4. Fasten the drop cable to the riser pipe with cable
clips as you connect the pipes.
Securing the pump with a straining wire
Do not use the straining wire to carry the
load of both pump and riser pipe when you
lower the pump or pull the pump out of the
borehole.
1. Secure the pump with an unloaded straining wire.
TM070053
Straining wire

English (GB)

2. Lower the pump to the required depth and
complete the installation with a borehole seal.
3. Loosen the straining wire so that it becomes
unloaded and lock the straining wire to the
borehole seal with wire locks.
3.3 Electrical connection
DANGER
Electric shock
Death or serious personal injury
‐Switch off the power supply before you
start any work on the product.
‐Make sure that the power supply can-
not be switched on accidentally.
DANGER
Electric shock
Death or serious personal injury
‐The product must be earthed.
‐Connect the product permanently to
the fixed wiring via an external main
switch with a minimum contact gap of 3
mm in all poles.
WARNING
Electric shock
Death or serious personal injury
‐Do not lift the product by the power ca-
ble.
All electrical connections must be carried
out by a qualified electrician in accordance
with local regulations.
Check that the supply voltage and fre-
quency correspond to the values stated on
the nameplate.
If the power cable is damaged, it must be
replaced by the manufacturer, the manu-
facturer's service partner or a similarly
qualified person.
The cross-sectional area of the submersi-
ble drop cable must be large enough to
meet the voltage requirements.
Never connect the product to an external
frequency converter.
3.3.1 Residual-current circuit breakers
WARNING
Electric shock
Death or serious personal injury
‐Use a suitable type of GFCI capable of
handling earth fault currents with DC
content (pulsating DC).
If the pump is connected to an electrical installation
where a ground fault circuit interrupter (GFCI) is used
for additional protection, this ground Fault Circuit
Interrupter shall be able to trip when ground fault
currents with DC content occur.
If national legislation requires a Residual Current
Device (RCD) or equivalent in the electrical
installation, this must be type B or better, due to the
nature of the constant DC leakage current.
The residual-current circuit breaker must be marked
like this:
TM066230
Take into account the total leakage current of all the
electrical equipment in the installation.
