The oor where you plan to position the unit must be:
• perfectly at and without roughness;

• able to support the weight of the equipment considering an appropriate safety margin (see

The air ducts (not supplied) must be connected directly to the unit: when assembly is completed,
they must not be stretched, in order to avoid damage and transmission of vibrations.
To ensure the
seal of the connections and the integrity of the unit, it is essential that the air ducts be supported by
special brackets (not supplied) that do not weigh directly on the unit.
