Use cable according to rules with 4 leads (3+earth/ground) for three
phase version.
4.3 Install the pump
4.3.1 Install the pump on a concrete foundation
For information about the pump base and anchor holes, see
13
.
1.
Put the pump onto the concrete foundation or equivalent metal
structure.
To avoid vibrations, provide vibration-damping supports between
the pump and the foundation.
2.
Remove the plugs covering the ports.
3.
Align the pump and piping flanges on both sides of the pump.
Check the alignment of the bolts.
4.
Fasten the piping with bolts to the pump.
Do not force the piping into place.
5.
Anchor the pump securely with bolts to the concrete foundation or
metal structure.
4.3.2 Electrical installation
1.
If it is necessary to rotate the motor in order to change the posi-
tion of the terminal board: do not disassemble the electric pump
but contact our Sales and Service Department.
2.
Remove the screws of the terminal box cover.
3.
Connect and fasten the power cables according to the applicable
wiring diagram.
For wiring diagrams, see the Installation and operating instruc-
tions manual of the motor.
a)
Connect the earth (ground) lead.
Make sure that the earth (ground) lead is longer than the
phase leads.
b)
Connect the phase leads.
4.
Replace the terminal box cover.
NOTICE:
Tighten the cable glands carefully to ensure protection against ca-
ble slipping and humidity entering the terminal box.
5.
If the motor is not equipped with automatic reset thermal protec-
tion, then adjust the overload protection according to the list be-
low.
• 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 example 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 cur-
rent (only for three-phase motors).
5 Commissioning, Startup,
Operation, and Shutdown
Precautions
WARNING:
• Make sure that the drained liquid does not cause dam-
age or injuries.
• The motor protectors can cause the motor to restart un-
expectedly. 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) during 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 rated 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 conditions. Drain all liquid
that is inside the pump. Failure to do so can cause liquid to freeze
and damage 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 (nomi-
nal pressure PN) for the pump.
• Do not use the pump if cavitation occurs. Cavitation can damage
the internal components.
• If you pump hot liquid, you must guarantee a minimum pressure
on the suction side to prevent cavitation.
• To prevent overheating of the internal pump-components, make
sure that a minimum liquid flow is always guaranteed when the
pump is running. The running time under these conditions must
not exceed a few seconds. If minimum water flow cannot be ach-
ieved, then a bypass or recirculate line is recommended. Refer to
the minimal nominal flow rate values given in the Appendix.

Operating Instructions manual of the Motor.
5.1 Prime the pump
WARNING:
To Opening of equipment through the plugs is possible only
under non-active conditions or if it is unavoidable, during pri-
ming phase, necessary precautions must be taken into ac-
count.
For information about the plug placement, see
Installations with liquid level above the pump (suction head)
For an illustration that shows the pump parts, see
1.
Close the on-off valve located downstream from the pump. Select
the applicable steps:
2.
Series 1, 3, 5:
a)
Loosen the drain plug pin (2).
b)
Remove the fill and vent plug (1) and open the on-off valve
upstream until the liquid flows out of the hole.
c)
Tighten the drain plug pin (2).
d)
Replace the fill and vent plug (1).
3.
Series 10, 15, 22, 33, 46, 66, 92, 125:
a)
Remove the fill and vent plug (1) and open the on/off valve
upstream until the water flows out of the hole.
b)
Close the fill and vent plug (1). Fill plug (3) can be used in-
stead of (1).
Installations with liquid level below the pump (suction lift)
For an illustration that shows the pump parts, see
1.
Open the on-off valve located upstream from the pump and close
the on-off valve downstream. Select the applicable steps:
2.
Series 1, 3, 5:
a)
Loosen the drain plug pin (2).
b)
Remove the fill and vent plug (1) and use a funnel to fill the
pump until water flows out of the hole.
c)
Tighten the drain plug pin (2).
d)
Replace the fill and vent plug (1).
3.
Series 10, 15, 22, 33, 46, 66, 92, 125:
a)
Remove the fill and vent plug (1) and use a funnel (4) to fill
the pump until water flows out of the hole.
b)
Replace the fill and vent plug (1). Fill plug (3) can be used
instead of (1).
5.2 Check the rotation direction (three-phase motor)
Follow this procedure before start-up.
1.
Locate the arrows on the adaptor or the motor fan cover to deter-
mine the correct rotation direction.
2.
Start the motor.
