2. SAFETY
Read this data sheet carefully before installing and starting up.
Pay special attention to the points concerning the safety of the
equipment for the intermediate or end user.
2.1 Symbols used in the manual
Calls attention to a potential risk that might affect safety.
Instruction concerning electricity.
Warning.
Before any putting-into-service of the motor-pump, make sure
the coupling protective cover is present.
3. TRANSPORT AND STORAGE
When taking delivery of the equipment, check that it has not
been damaged in transit. If anything is found wrong, take the
necessary steps with the carrier within the allowed time.
If the equipment delivered is to be installed at a later
time, store it in a dry place and protect it from
impacts and outside influences (moisture, frost, etc.).
The set will be handled taking it at the baseplate and preferably
using blankets. Never use the motor eye bolts (
see FIG. 1
).
In case of frost risk, and for prolonged shutdowns, drain the pump
and auxiliary circuits, close the isolating valves.
Storage shorter than 3 months:
all zones, before starting up, turn the motor-pump by hand.
Storage shorter than 6 months:
temperate zones, before starting up, turn the motor-pump by hand;
other zones:
Dismantle the pump to replace all gaskets and all fittings.
Check the bearings (non oxidation - lubrication).
Check the coupling catches.
Check for perfect lubrication.
In any case, check the alignment of shafts.
After prolonged shutdown, never start the pump without having
performed the checks of first putting into service.
For pumps with IP55 motors : the plugs blanking the condensates
discharge ports must be removed for the whole time the equip-
ment is in storage (these plugs are supplied with the pump).

5. INSTALLATION (SEE FIG.2)
5.1 Mounting
Install the motor-pump in a place easy to reach, protected from
frost, and as close as possible to the water drawing point in order
to limit the suction head loss.
- Mounting on concrete foundation (
D
), with fastening through
anchor bolts (
A - FIG.3
); the foundation should be widely sized,
its weight should be about 2 to 3 times the motor-pump weight.
- Under the concrete foundation, provide for insulating material (cork
or reinforced rubber) to prevent the propagation of vibrations.
Motor-pump anchoring (see FIG.3)
- During anchoring operations, do not flange the pump to pipes.
Continually check the motor-pump levels and alignment (see
next paragraph: ”Check of the shaft-line alignment”).
- Clean the foundation (
D
), position anchoring rods (
A
) in the
holes, place the motor-pump and install nuts (
A
).
- Insert steel wedges (
B
) of thickness
≥
10 mm between baseplate (
E
) and
the foundation, distributed on either side of anchor bolts (
A - FIG.3
).
- The wedging should provide the motor-pump with perfect hori-
zontal position and place it at the required height.
- Underpour concrete in foundation holes (
C
). After concrete set-
ting, progressively tighten baseplate (
E
) on the wedges while
checking the alignment and levels.
- Pour low shrinkage concrete inside the base
(E)
through hole
(F)
.
Do not use rapid hardening cement.

Check of the shaft-line alignment according to standard NFE
44190 (see FIG.6).
The motor pump alignment, carefully performed in
factory, must always be checked and corrected
after final attachment of the baseplate and after disassembly-
assembly operations (see FIG.6).
