quate measures.
2. SAFETY
Read this instructions carefully before installing and starting up. Pay
special attention to the points concerning the safety of the equip-
ment as regards the intermediate or final user.
2.1 Symbols used in the manual
Security instruction : non respect can induce injury.

3. TRANSPORT, HANDLING AND STORAGE
When receiving the material, check that there has been no damage
during the transport. If any defect has been stated, take all necessa-
ry steps with the carrier within the allowed time.
If the delivered material is to be installed later on,
store it in a dry place and protect it from impacts
and any outside influences (humidity, frost etc...).
Due to high position of centre of gravity and small ground surfa-
ce of this type of pumps, beware of unstability during handling to
avoid any falling down and take necessary means to avoid inju-
ries or damaging.
Handle the pump carefully so as not to alter the goemetry and the
alignment of the unit.
In no case the pump must be lifted by the conver-
ter, use some lifting hooks for any handling.

5. INSTALLATION
Two standard types :
• FIG. 1 : pump in suction
• FIG. 2 : pump under pressure
on storage tank (
ref. 9
) or town water
supply (
ref. 10
).
5.1 Mounting
Install the pump in a place easy to reach, protected against extrema
conditions (rain and sun in excess, frost) and as close as possible from
the drawing point.
For heavy pumps provide a point of attachment (lifting hook) in the
pump axis (
ref. 12
) to facilitate removal.
Install the pump on a concrete block (at least 10 cm high) (
ref. 13
)
and fix with anchor bolts (
installation plan see FIG. 3
).
Foresee an insulating material under the concrete block (cork or rein-
forced rubber) to avoid any noise and vibration transmission into the
installation.
Before final tightening of anchor bolts, ensure that the pump axis is
