pump

The control panel must be equipped with a
dry-running protection system to which a
pressure switch, float switch, probes, or other
suitable device is connected.

The following devices are recommended for
use on the suction side of the pump:
–
When the liquid is pumped from a
water system, 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
order to ensure whether a
protection device is provided if
another motor other than the
standard is used.

If the motor is equipped with
automatic thermal protectors, be
aware of the risk of unexpected
starts in connection to overload.
Do not use such motors 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:
Frequency Hz Phase ~
50 3
60 3
Use cable according to rules with 3 leads
(2+earth/ground) for single phase versions and with
4 leads (3+earth/ground) for three-phase version.

Mechanical installation

Check the following before installation:
1
Fuses aM (motor starting), or magneto-thermal switch with
curve C and Icn ≥ 4,5 kA or other equivalent device.
2
Overload thermal relay with trip class 10A + fuses aM (motor
starting) or motor protection magneto-thermal switch with
starting class 10A.

380/660 ± 10

Use a concrete of compressive strength
class C12/15 which meets the requirements
of exposure class XC1 to EN 206-1.

The mounting surface must have set and
must be completely horizontal and even.

Observe the weights indicated.
Install the pump set
Check that the foundation has been prepared in
accordance with the dimensions given in the
outline drawing/general arrangement drawing.
For information about the pump base and anchor
holes, see dimensional drawing.
1. Position the pump set on the foundation and
level it with the help of a spirit level that is
placed on the discharge port.
The permissible deviation is 0.5 mm/m.
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 Piping checklist
Check that the following are adhered to:

The suction lift line has been laid with a rising
slope, at positive suction head line with a
downward slope towards the pump.

The nominal diameters of the pipelines are at
least equal to the nominal diameters of the
pump ports.

The pipelines have been anchored in close
proximity to the pump and connected without
transmitting any stresses or strains.
CAUTION:
Welding beads, scale and other
impurities in the piping damage the
pump.

Free the piping from any impurities.

If necessary, install a filter.
4.3.3

Electrical installation

1. Remove the screws of the terminal box cover.
2. Connect and fasten the power cables according
to the applicable wiring diagram.
For wiring diagrams, see
diagrams are also available on the back of the
terminal box cover.
a) Connect the ground (earth) lead.
Make sure that the ground (earth) lead is
longer than the phase leads.
b) Connect the phase leads.
3. Mount the terminal box cover.
NOTICE:
Tighten the cable glands carefully to ensure
protection against cable slipping and humidity
entering the terminal box.
4. If the motor is not equipped with automatic
reset thermal protection, then adjust the
overload protection 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)
