POSITIONING

5.1 Handling, lifting and positioning the unit
Before handling the unit, read with care the following instructions, the information on the yellow label on the product and in the
dimensional drawing, and the instruction manual of the lifting equipment used.
Handling and transport must be carried out by qualified personnel using suitable personal protective equipment and materials
suited to the weight and size of the unit.
The units can be lifted using either tubular rods or eye-bolts. Follow the procedure below:
-
Handle the unit at an ambient temperature above -10°C and when there is no wind
-
Make sure that all the panels and connections (bolts, rivets, etc.) are not damaged and are fastened and secured
correctly
-
Use all, and only, the lifting points indicated in the dimensional drawing and marked on the unit
-
Use cables of suitable load-bearing capacity and length, as indicated in the dimensional drawing.
-
Make sure that the cables are securely fastened to the unit:
-
It is obligatory to use a sling bar of suitable weight-bearing capacity to guarantee stability when lifting and to prevent the cables from coming in contact with the unit
-
Handle the unit carefully without making sudden movements or tilting the unit at an angle of more than 6°.
-
Keep at a safe distance and do not, for any reason, stand with parts of the body under or near the lifted unit
The unit is not designed for lifting and handling by forklift truck.
It can be moved by means of rollers.
The surface on which the unit is placed must be level and sufficiently strong to take the weight of the machine when it is full of water and running.
To reduce vibrations to the supporting structures, assemble vibration dampers at each fastening point indicated in the dimensional drawing. Install the vibration dampers under
the base with the unit lifted no more than 200 mm off the ground and avoid standing with parts of the body under the unit.
In any case, always secure the unit on the ground. The vibration dampers may extend outside the span of the machine and, in which case, will require suitable support.
In the case of installation on a raised surface, make sure that the handle of the power disconnector is easy to access and at a height of between 0.6m and 1.9m above the floor
(EN60204-1).
