Install each air duct making sure that:
• It does not weigh down on the equipment.
• It allows maintenance operations.
• It is adequately protected to prevent the accidental intrusion
of materials inside the equipment.
• The connection to the outside must be done with suitable,
non-flammable piping.
• The total equivalent length of the extraction pipes plus the
delivery, including grilles, must not exceed 12 m.
