OCATION AND ASSEMBLING
The unit must be handled with care to avoid transport damage. Thus
we recommend:
- For transport in a container, one must be selected that has an easy
load and unload to the installation location.
- Do not dispose of the skids nor the packaging materials until the
machine is in its fi nal location.
- The unit must be lifted and fi xed with care and without inclination
(maximum inclination 15º), since it could harm its operation. Please
refer to the weight and the gravity centre coordinates of each model
stated in the following table.
- The unit is designed to be transported safely by using a forklift truck.
The forks of the forklift truck must ensure that the centre of gravity
of the unit remains within the forks, because a misbalance in the
transport may cause the unit to turn over and fall from the forklift
truck. Check also that the length of the fork entries, so that the entire
weight-bearing structure of the unit can be supported on the forklift
truck. This also prevents the possible introduction of the truck’s fork
into functional parts of the unit that may cause damage to the unit.
The standards and recommendations of the forklift truck must also
be respected with regards to the maximum load, inclination of the
panel, elevation of the load for transport, and, in particular, the
maximum speed.

RANSPORT
- Finally, the unit must be freed from the skids so that the inserts
available for the silent-blocks can be accessed. Each skid is fi xed
to the crossbar using M4 screws.

Assembling
- These units can be installed on the fl oor or on a brick frame or steel
pro fi le.
• Foresee appropriate damping devices in these fi xtures to ensure
that noise and vibration transmission is avoided.
Location designation
Before moving the unit, make sure that all panels are fastened in place.
Lift and lower with care.
When choosing the location, whatever may be the selected fashion, the
following precautions have to be taken into consideration:
- It is mandatory to comply with norm UNE-EN 378-3 on Safety
and Environmental Requirements. Part 3: “In situ” installation and
protection to people.
- The area where the unit will be located must be perfectly accessible
for cleaning and maintenance operations (check minimum free space
for maintenance). Leave enough space for air circulation around the
unit.
- It is necessary to check that the structure supports the unit’s weight
(please see weight in the centre of gravity table).
• In the event of assembling directly on silent-blocks to the ground,
it is recommended that a template of the unit’s footprint with the
anchoring points of the silent-blocks be made.
• With the help of the crane or the forklift truck, the unit will be raised
to a suf fi cient height that the silent-blocks can be screwed into its
base. The 4 silent-blocks must remain oblique to the unit.
• M10 metric threads have been provided for their placement in
the supports indicated in the following section “Anchorage for
silent-blocks”. A hex key 17 or Allen wrench 8 will be used for this
operation based on the type of screw used.
This image shows how the silent-block option that can be supplied
for this unit is fi xed to the unit.
• Check that the unit is perfectly levelled.
