
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:
 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.
 Make sure that the control panel
and any control devices are
suitable for installation in the
selected location. The regulation
in force is the Directive
1999/92/EC-ATEX 137 regarding
the safety and health of personnel
who may be exposed to the risk of
explosive atmospheres.
 All motors, which are supplied with
pump or mounted by the customer
aftermarket, must have an axially
locked bearing.
 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 and sprinkler
systems.

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.
All motors, supplied with pump or mounted by
the customer aftermarket , must have an axially
locked bearing
In general, motors can operate under the
following mains voltage tolerances:

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.

Install the pump

4.4.1 Mechanical installation
Check the following before installation:

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
For examples of horizontal installations, see
Figure 16.
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 Figure 17.
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 0.2 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. Use shims for height compensation, if
necessary.
Always fit shims, if any, immediately to the
left and right of the foundation bolts
between the baseplate/foundation. For a
bolt-to-bolt distance (L) > 800 mm, fit extra
shims halfway between the bolt holes.
6. Make sure that all shims lie perfectly flush.
7. Insert the foundation bolts into the holes
provided.
