en - Original instructions
16
technicians and in compliance with
the regulations in force.
•Before starting work on the unit,
make sure that the unit and the con-
trol panel are isolated from the power
supply and cannot be energized. This
applies to the control circuit as well.
Grounding (earthing)
Electrical Hazard:
•Always connect the external protec-
tion conductor to ground (earth) ter-
minal before making other electrical
connections.
• You must ground (earth) all electrical
equipment. This applies to the pump
equipment, the driver, and any moni-
toring equipment. Test the ground
(earth) lead to verify that it is connect-
ed correctly.
• If the motor cable is jerked loose by
mistake, the ground (earth) conductor
should be the last conductor to come
loose from its terminal. Make sure
that the ground (earth) conductor is
longer than the phase conductors.
This applies to both ends of the motor
cable.
• Add additional protection against le-
thal shock. Install a high-sensitivity
differential switch (30 mA) [residual
current device RCD].
4.1 Facility requirements
4.1.1 Pump location
DANGER:
Do not use this unit in environments that
may contain flammable/explosive or
chemically aggressive gases or powders.
Guidelines
Observe the following guidelines regarding the loca-
tion of the product:
•Make sure that no obstructions hinder the normal
flow of the cooling air that is delivered by the mo-
tor fan.
• Make sure that the installation area is protected
from any fluid leaks, or flooding.
• If possible, place the pump slightly higher than
the floor level.
• The ambient temperature must be between 0°C
(+32°F) and +40°C (+104°F).
• The relative humidity of the ambient air must be
less than 50% at +40°C (+104°F).
• Contact the Sales and Service Department if:
– The relative air humidity conditions exceed
the guidelines.
– The room temperature exceeds +40°C
(+104°F).
– The unit is located more than 1000 m
(3000 ft) above the sea level. The motor per-
formance may need to be de-rated or re-
placed with a more powerful motor.
For information about which value to de-rate the mo-
tor with, see Table 8 (page 337).
Pump positions and clearance
Provide adequate light and clearance around the
pump. Make sure that it is easily accessible for in-
stallation and maintenance operations.
Installation above liquid source (suction lift)
The theoretical maximum suction height of any
pump is 10.33m. In practice, the following affect the
suction capacity of the pump:
• Temperature of the liquid
• Elevation above the sea level (in an open sys-
tem)
• System pressure (in a closed system)
• Resistance of the pipes
• Own intrinsic flow resistance of the pump
• Height differences
The following equation is used to calculate the maxi-
mum height above the liquid level which the pump
can be installed:
(pb*10.2 - Z) ≥ NPSH + Hf + Hv + 0.5
pbBarometric pressure in bar (in closed sys-
tem is system pressure)
NPSH Value in meter of the pump intrinsic flow re-
sistance
HfTotal losses in meters caused by passage of
liquid in the suction pipe of the pump
HvSteam pressure in meters that correspond
to the temperature of the liquid T °C
0.5 Recommended safety margin (m)
Z Maximum height at which the pump can be
installed (m)
(pb*10.2 - Z) must always be a positive number.
For more information, see Figure 9 (page 337).
NOTICE:
Do not exceed the pumps suction capacity as this
could cause cavitation and damage the pump.
4.1.2 Piping requirements
Precautions
WARNING:
• Use pipes suited to the maximum
working pressure of the pump. Fail-
ure to do so can cause the system to
rupture, with the risk of injury.
• Make sure that all connections are
performed by qualified installation
technicians and in compliance with
the regulations in force.
NOTICE:
Observe all regulations issued by authorities having
jurisdiction and by companies managing the public
water supplies if the pump is connected to a public
water system. If required, install appropriate back-
flow-prevention device on the suction side.
Piping checklist
Check that the following requirements are met:
en - Original instructions
17
• All piping is independently supported, piping
must not place a burden on the unit.
•Flexible pipes or unions are used, in order to
avoid transmission of pump vibrations to the
pipes and vice versa.
• Use wide bends, avoid using elbows which
cause excessive flow resistance.
• The suction piping is perfectly sealed and air-
tight.
• If the pump is used in an open circuit, then the di-
ameter of the suction pipe is suited to the instal-
lation conditions. The suction pipe must not be
smaller than the diameter of the suction port.
• If the suction piping must be larger than the suc-
tion side of the pump, then an eccentric pipe re-
ducer is installed.
• If the pump is placed above liquid level, a foot
valve is installed at the end of the suction piping.
• The foot valve is fully immersed into the liquid so
that air cannot enter through the suction vortex,
when the liquid is at the minimum level and the
pump is installed above the liquid source.
• Appropriately sized on-off valves are installed on
the suction piping and on the delivery piping
(downstream to the check valve) for regulation of
the pump capacity, for pump inspection, and for
maintenance.
• Appropriately sized on-off valve is installed on
the delivery piping (downstream to the check
valve) for regulation of the pump capacity, for
pump inspection, and for maintenance.
• In order to prevent back flow into the pump when
pump is turned off a check valve is installed on
the delivery piping.
WARNING:
Do not use the on-off valve on the dis-
charge side in the closed position in or-
der to throttle the pump for more than a
few seconds. If the pump must operate
with the discharge side closed for more
than a few seconds, a bypass circuit
must be installed to prevent overheating
of the liquid inside the pump.
For illustrations that show the piping requirements,
see Figure 10 (page 338) and Figure 11 (page
338).
4.2 Electrical requirements
• The local regulations in force overrule these
specified requirements.
• In the case of fire fighting systems (hydrants
and/or sprinklers), check the local regulations in
force.
Electrical connection checklist
Check that the following requirements are met:
• The electrical leads are protected from high tem-
perature, vibrations, and collisions.
• The power supply line is provided with:
– A short-circuit protection device
– A mains isolator switch with a contact gap of
at least 3 mm
The electrical control panel checklist
NOTICE:
The control panel must match the ratings of the elec-
tric pump. Improper combinations could fail to guar-
antee the protection of the motor.
Check that the following requirements are met:
•The control panel must protect the motor against
overload and short-circuit.
• Install the correct overload protection (thermal re-
lay or motor protector).
Pump Type Protection
Single phase standard
electric pump ≤ 2.2 kW – Built-in automatic

• The control panel must be equipped with a dry-
running protection system to which a pressure
switch, float switch, probes, or other suitable de-
vice is connected.
•The following devices are recommended for use
on the suction side of the pump:
– When the liquid is pumped from a water sys-
tem, use a pressure switch.
– When the liquid is pumped from a storage
tank or reservoir, use a float switch or probes.
• When thermal relays are used, relays that are
sensitive to phase failure are recommended.
The motor checklist
WARNING:
• Read the operating instructions in or-
der to ensure whether a protection
device is provided if another motor
other than the standard is used.
• If the motor is equipped with automat-
ic thermal protectors, be aware of the
risk of unexpected starts in connec-
tion to overload. Do not use such mo-
tors for fire-fighting applications.
NOTICE:
• Only use dynamically balanced motors with a
half-sized key in the shaft extension (IEC
60034-14) and with normal vibration rate (N).
• The mains voltage and frequency must agree
with the specifications on the data plate.
In general, motors can operate under the following
mains voltage tolerances:
3fuses aM (motor starting), or magneto-thermal switch with curve C and Icn ≥ 4,5 kA or other equivalent device.

19
Tighten the cable glands carefully to ensure pro-
tection against cable slipping and humidity en-
tering the terminal box.
4. If the motor is not equipped with automatic reset
thermal protection, then adjust the overload pro-
tection according to the list below.
– If the motor is used with full load, then set
the value to the nominal current value of
electric pump (data plate)
– If the motor is used with partial load, then set
the value to the operating current (for exam-
ple measured with a current pincer).
– If the pump has a star-delta starting system,
then adjust the thermal relay to 58% of the
nominal current or operating current (only for
three-phase motors).
5 Commissioning, Startup,
Operation, and Shutdown
Precautions
WARNING:
•Make sure that the drained liquid
does not cause damage or injuries.
• The motor protectors can cause the
motor to restart unexpectedly. This
could result in serious injury.
• Never operate the pump without the
coupling guard correctly installed.
CAUTION:
•The outer surfaces of the pump and
motor can exceed 40ºC (104ºF) dur-
ing operation. Do not touch with any
part of the body without protective
gear.
• Do not put any combustible material
near the pump.
NOTICE:
•Never operate the pump below the minimum rat-
ed flow, when dry, or without prime.
• Never operate the pump with the delivery ON-
OFF valve closed for longer than a few seconds.
• Never operate the pump with the suction ON-
OFF valve closed.
• Do not expose an idle pump to freezing condi-
tions. Drain all liquid that is inside the pump. Fail-
ure to do so can cause liquid to freeze and dam-
age the pump.
• The sum of the pressure on the suction side
(mains, gravity tank) and the maximum pressure
that is delivered by the pump must not exceed
the maximum working pressure that is allowed
(nominal pressure PN) for the pump.
• Do not use the pump if cavitation occurs. Cavita-
tion can damage the internal components.

fan cover to determine the correct rotation direc-
tion.
2. Start the motor.
3. Quickly check the direction of rotation through
the coupling guard or through the motor fan
cover.
4. Stop the motor.
5. If the rotation direction is incorrect, then do as
follows:
a) Disconnect the power supply.
b) In the terminal board of the motor or in the elec-
tric control panel, exchange the position of two
of the three wires of the supply cable.
For the wiring diagrams, see Figure 13 (page
341).
c) Check the direction of rotation again.
5.3 Start the pump
The responsibility for checking the correct flow and
the temperature of the pumped liquid rests with the
installer or owner.

6 Maintenance
Precautions
Electrical Hazard:
Disconnect and lock out electrical power
before installing or servicing the unit.
WARNING:
•Maintenance and service must be
performed by skilled and qualified
personnel only.
• Observe accident prevention regula-
tions in force.
• Use suitable equipment and protec-
tion.
• Make sure that the drained liquid
does not cause damage or injuries.
6.1 Service
If the user wishes to schedule regular maintenance
deadlines, they are dependent on the type of pump-
ed liquid and on the operating conditions of the
pump.
Contact the local sales and service representative
for any requests or information regarding routine
maintenance or service.
Extraordinary maintenance may be necessary to
clean the liquid end and/or replace worn parts.
Motor bearings
After approximately five years, the grease in the mo-
tor bearings is so aged that a replacement of the
bearings is recommended. The bearings must be re-
placed after 25000 operating hours or according to
the motor supplier maintenance instructions, which-
ever is shorter.
