2. In the event of in-transit damage, assess the exact damage, document it and
notify KSB or the supplying dealer and the insurer about the damage in writing
immediately.
NOTE
The pump set is supplied by the manufacturer/supplier in packaging which largely
prevents sagging or other damage during transport and/or storage.
3.2 Transport

▷Never suspend the pump (set) from the power cable.
▷Prevent the pump (set) from getting knocked or dropped.
▷Always secure a pump set in upright position against tipping over.
▷Wear personal protective equipment.
Use lifting equipment which is suitable for the weight of the pump set.
Make sure that the power cable is not kinked or damaged during transport.
3.3 Storage/preservation
If commissioning is to take place some time after delivery, we recommend that the
following measures be taken:
WARNING
Pump set tilting or rolling off
Risk of personal injury!
▷Always secure vertically positioned pump sets against tipping over.
▷Always secure horizontally positioned pump sets against rolling off.
CAUTION
Damage during storage due to frost, humidity, dirt, UV radiation or vermin
Corrosion/contamination of the pump!
▷Store the pump (set) in a dry, dark, frost-proof room not exposed to sunlight
where the atmospheric humidity is as constant as possible.

4.5 Configuration and function
The fluid enters the pump via the suction casing. It is accelerated outward by the
rotating impellers. In the flow passage of the diffusers and the pump casing the
kinetic energy of the fluid is converted into pressure energy. The fluid is pumped to
the discharge side, where it leaves the pump. At the rear side of the impeller, the
motor shaft enters the casing via the bearing cover. The shaft passage is sealed by a
double mechanical seal. The shaft is supported by rolling element bearings.

5.1 Installing the pump set
CAUTION
Incorrect installation
Damage to the machine
▷The pump set must always be installed in a vertical position.
▷Never suspend the pump set by the power cable.
NOTE
We recommend securing the suspended pump set with a safety rope or chain made
of indestructible material at all times. If a plastic pipe or hose is used as a discharge
line, the safety rope must be used for lowering, fastening and pulling up the pump
set.
Observe the following when selecting a place of installation:
▪Never install the pump set too close to the inner walls of the tank / rainwater
storage tank.
▪Observe the installation heights of max. 20m.
▪To prevent intake of sand install the pump set at a distance of at least 0.5m from
the bottom of the well.
The pump set can be installed as follows:
≥ 0,5 m ≤ 20 m

5.2 Connecting the piping
DANGER
Using damaged power cables in the tank / rainwater storage tank
Electric shock!
▷Do not kink the power cable. Observe the minimum bending radius1) of the
cable. Do not drag the cable over sharp edges.
▷Fasten the power cable to the riser or piping every 3m with suitable fasteners
(e.g. cable clips, sleeves). (Provide sufficient slack between the fasteners to
prevent the power cable from any tension caused by the expansion of the pipe
under load.)
▷Do not use any tools, equipment or accessories with sharp edges (e.g. sharp-
edged pipe sockets) for the installation.
WARNING
Persons falling into unsecured tanks / rainwater storage tanks
Risk of injury!
▷Always secure open tanks / rainwater storage tanks during the entire
installation procedure to prevent persons from falling in.
▷Suitably fence off the work area.
CAUTION
Pump set falling into the tank / rainwater storage tank
Damage to the pump set!
▷Secure the pump set during the entire installation procedure.
▷Dimension any securing devices (supporting clamps, supports, etc.) so that they
can carry all weights during the installation.
1) See cable manufacturer's documentation or DINVDE0298-3.

5 Installation at Site
18 of 32 Ixo N
CAUTION
Unsuitable pipeline
Faulty operation of the pump!
▷If using plastic pipelines, make sure they are designed to withstand the pump
pressure.
▷Do not kink the plastic pipeline.
CAUTION
Incorrect assembly
Damage to the pump set!
▷Never hold or transport the pump set by its power cable.
Installation information
▪The pump sets can be connected to pipelines with a G 11/4 thread (DN32).
▪The inside diameter of the riser must not be smaller than the pump connection
with a thread of G 11/4 (DN32).
▪Position the pump sets vertically with the discharge nozzle on top.
▪The pump set can be supported by the metal discharge line. For this purpose,
firmly tighten the threaded connections to prevent them from loosening.
NOTE
Using a discharge line of a larger diameter is recommended in the case of very high
static heads or very long pipelines in order to prevent pressure losses.
1. Install the pipelines in accordance with the manufacturer's documentation.
2. Lower the pump set into the tank / rainwater storage tank.
5.3 Electrical connection
DANGER
Electrical connection work by unqualified personnel
Danger of death from electric shock!
▷Always have the electrical connections installed by a trained and qualified
electrician.
▷Observe regulations IEC60364.
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷Observe the technical specifications of the local energy supply companies.
DANGER
Connection of damaged power cables
Danger of death from electric shock!
▷Check the power cables for damage before connecting them.
▷Never connect damaged power cables.
▷Replace damaged power cables.

5 Installation at Site

Ixo N
CAUTION
Galvanic corrosion using the pump set in water containing chloride (or in salt
water)
Damage to the pump set!
▷Connect the pump set to earth, also if using non-metal pipelines and safety
ropes.
▪Install a device for switching off each phase conductor at the mains (switch).
Provide a minimum opening distance of 3mm for the contacts.
▪If the water level cannot be checked visually, a float switch or another protective
device must be installed to prevent dry running of the pump set and to set the
water levels for automatic start-up/stop of the pump set.
▪Pump sets with single-phase AC motor (IxoNE)
These pump sets are fitted with a capacitor, thermal protection plug and,
optionally, with a float switch. Connect the plug to a socket with earth contact.
Excessive temperatures lead to the motor cutting out. When the winding
temperature decreases again (after 2 to 4 minutes), the thermal switch starts up
the motor again.
▪Pump sets with three-phase motor (Ixo N D)
For these pump sets install a motor protection switch (curve type D) in the
control cabinet. Observe the current requirement indicated on the name plate.

6 Commissioning/Start-up/Shutdown
6.1 Commissioning/Start-up
6.1.1 Starting up and stopping
CAUTION
Prolonged operation of the pump set against a closed shut-off element
Damage to the pump set!
▷Never operate the pump set against a closed shut-off element for more than
5minutes.
CAUTION
Insufficient lubrication of the mechanical seal
Damage to the mechanical seal!
▷Never operate the pump set in dry condition, not even for testing.
NOTE
In the event of any malfunctions immediately disconnect the pump set from the
mains.
The pump set starts pumping as soon as it is connected to the power supply. When
the power supply is interrupted, the pump set stops.
üThe minimum immersion depth of 100mm has been observed.
1. For three-phase motors check the direction of rotation.
To do so, start the pump set (with the shut-off element in any open position)
and check the pressure (with a pressure gauge) or the flow rate (visually). Then
disconnect the pump set from the power supply. Interchange two phase
connections in the control cabinet. Re-start the pump set. Check the pressure
and flow rate again. The correct direction of rotation results in a significantly
higher pressure and larger flow rate.
2. Verify that the pump set operates within its operating range and that the
power intake indicated on the name plate is not exceeded. If necessary, adjust
the shut-off element in the discharge line or the pressure switches (if any).
