4.1 General precautions
Before starting, make sure that the safety instructions shown in Introduction and Safety on
page 5 have been fully read and understood.
WARNING:
All the hydraulic and electrical connections must be completed by a technician possessing the
technical
-professional requirements outlined in the current regulations.
WARNING:
Always wear personal protective equipment.
WARNING:
Always use suitable working tools.
4.2 Mechanical installation
4.2.1 Precautions
WARNING: Risk of injury due to improper floor installation
Install the unit on a concrete or metal
foundation base sufficiently strong to ensure permanent
and rigid support, suitable for the size and weight of the unit and as flat and even as possible.
4.2.2 Installation area
1. Follow the provisions in Operating environmenton page 33.
2. Place the unit in a raised position in relation to the floor.
3. Check that the air clearance between the wall and the motor fan grid is:
•≥ 100 mm (4 in), to ensure suitable ventilation
•≥ 300 mm (12 in), to allow inspection and removal of the motor.
4. Make sure that any leaks will not cause flooding to the installation area or submerge the
unit.
5. Make sure that the unit is protected from sudden temperature changes
Permitted positions
Only install the unit in the horizontal position, to allow self-venting.
4.2.3 Installation on concrete foundation
Foundation requirements
•The concrete must have a compression resistance of C12/15 and meet the requirements of
exposure class XC1 according to EN 206-1
•Sizes must be appropriate for the sizes of the unit support plate
•The foundation weight must be ≥ 1.5 times the unit weight (≥ 5 times the weight of the unit
if a quieter operation is required)
•The surface should be as flat and level as possible.

Installation
1. Drill the tie rod holes in accordance with the quantity, diameter and centre distances shown
in the technical catalogue.
2. Insert the tie rods into the holes and secure them with chemical anchors.
3. Remove the caps of the suction and discharge ports.
4. Place the unit on the foundation by inserting the tie rods into the holes in the plate.
5. Level the unit with a spirit level on the shaft and discharge port: the maximum permitted
tolerance is 0.2 mm/m (0.0024 in/ft).
6. Align the suction and discharge ports to their piping.
7. If necessary, insert levelling shims between the plate and the foundation.
8. Tighten the nuts on the tie rods evenly and fully.

DANGER: Explosion due to static charge
Ensure that the base plate is earthed correctly.
Reducing vibrations
The motor and the flow of liquid in the piping can generate vibrations, which may be amplified
from the possible incorrect installation of the unit and the piping. See Hydraulic connection on
page 17.

4.3 Hydraulic connection
4.3.1 Precautions
WARNING:
The piping system must be sized to ensure safety at the maximum
operating pressure and
temperature.
WARNING: Danger of hot and/or toxic liquid escaping from non-sealed piping system
connections
Support the piping system independently to prevent them from weighing on the unit. Secure
the piping system to the unit po
rts making sure to comply with the permitted forces and
torques. Install appropriate gaskets between the unit and the piping system.
WARNING: Hot surface hazard
If the temperature exceeds 60°C (140°F), isolate the unit before touching it.
NOTE:
When carrying out welding activities never use the unit for grounding: risk of pitting damage
to the bearings.
CAUTION: Residues from welding work or other impurities in the pipes lead to pump damage
The type and the duration of the cleaning activity during the flush and pickling operations must
be in accordance with the used casing and sealing materials.
Use a filter with 0.5 mm mesh and 0.25 mm wire diameter made of corrosion
-resistant material.
Insert a filter with a section three times that of the pipeline.
4.3.2 Guidelines for the hydraulic system
1. Support the piping system independently to prevent them from weighing on the unit.
2. Remove any welding residues, deposits and impurities from the piping system in order to
avoid damage to the unit: the method and duration of the cleaning operation must be
adapted to the materials of the unit and the gaskets.
3. To reduce the transmission of vibrations between the unit and the system and vice versa,
install:
•Anti-vibration joints on the suction and discharge sides of the unit
•Dampers between the unit and the surface on which it is installed.
4. In order to reduce flow resistance, the pipe on the suction side must be:
•As short and as straight as possible
•For the section connected to the unit, straight and without bottlenecks, covering a
length equal to at least six times the diameter of the suction port
•Wider than the suction port; if necessary, install an eccentric reducer that is horizontal on
top
•Without bends; if this cannot be avoided, bends of a radius as wide as possible
•Without traps and 'goosenecks'
•With valves with a low specific flow resistance.
5. Install a check valve on the discharge side to prevent the liquid from flowing back into the
pump unit when this is at standstill.
6. Install a pressure gauge (or a vacuum pressure gauge, in case of suction lift installation) on
the suction side, and a pressure gauge on the discharge side, for checking the actual
operating pressure of the pump unit.

en – Original instructions
18 e-IXPS - Installation, Operation and Maintenance Instructions
7. To exclude the unit from the system for the purpose of maintenance, install:
•An on-off valve on the suction side
•An on-off valve on the discharge side, downstream the check valve and pressure gauge,
also useful for regulating the flow rate.
8. In case of suction lift installation, the suction pipe must have an increasing slope towards
the unit exceeding 2%; to avoid air pockets.
4.3.3 Forces and torques applicable to the ports
The figure and the table show the maximum forces and torques that the piping system should
be allowed to apply on the ports of the unit, depending on the material, with temperatures up
to 180°C (356°F).

4.5.1 Precautions
Electrical measures
DANGER: Electrical hazard
For the electrical connections, make sure to comply with the requirements of the IEC
60079-
14
standard.
DANGER: Electrical hazard:
Before starting work, check that the electric power supply is disconnected and locked out, to

20 e-IXPS - Installation, Operation and Maintenance Instructions
NOTE:
Only
use dynamically balanced motors with half-sized key at the shaft end (EN 60034-14), and
with normal vibration rate (N).
NOTE:
Only use three
-phase motors with sizes and powers in compliance with local laws / regulations
/ standards.
NOTE:
The mains voltage and frequency must match the specifications on the data plates.
Ground
DANGER: Electrical hazard due to static charge
Always connect the external protection conductor (ground) to the ground terminal before
attempting to make any other elec
trical connections.
DANGER: Electrical hazard
Install suitable systems for protection against indirect contact, in order to prevent lethal electric
shocks.
4.5.2 Guidelines for electrical connection
1. Check that the electrical leads are protected against:
•High temperature
•Vibrations
•Collisions
•Liquids.
2. Check that the power supply line is provided with:
•A short circuit protection device of appropriate size
4.5.3 Motor connection
1. Open the terminal box cover.
2. Insert the power cable in the cable gland.
3. Unsheathe the conductors.
4. Make sure that the protection conductor (ground) is longer than the phase conductors.
5. Refer to the wiring diagrams in the figure or inside the cover, insert the cores of the
conductors into the respective holes and tighten the nuts or screws.
6. Tighten the cable gland.
7. Close the cover and tighten the screws.
