OCATION AND ASSEMBLING

Location designation

Before moving the unit, it must be checked 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 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.
- Check that the unit is perfectly levelled.
- It is necessary to check that the surface of the fl oor or the structure
supports the weight of the unit (please, consult the weight of the unit
in the section "Anchorage for silent-blocks").
- Foresee appropriate damping devices in all the installation so that
noise and vibration transmission is avoided (refer to the "Anchorage
for silent-blocks").
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.

Minimum free space for commissioning and maintenance operations

0 , 5 m
With the help of the crane or the forklift truck, the unit will be raised
to a suffi cient height that the silent-blocks can be screwed into its
base. The 4 silent-blocks must remain oblique and the interiors
perpendicular 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.
Since it is an unit designed to work indoors, some specifi c installation
norms must be followed:
- Ensure that the location of the supply and return grilles does not
generate air recirculation.
- Check that there are no obstructions in the air supply and return grille
slats due to being tightly closed.
