Aeraulic connections
If present, the air ducts must be connected to the joints or the circular attachments that may be provided
on the unit. If these components were not provided with the machine, the coupling can be made by con-
necting directly to the machine's panels, making sure to insert a suitable anti-vibration system between
the unit and the duct.
If not using anti-vibration joints it is necessary to:
• Clean the joint surfaces between the duct and the machine/coil.
• Apply a gasket to the flange in order to prevent air infiltration.
• Carefully tighten the connecting screws.
• Use silicone on the gasket in order to optimise the seal.
If the connection is made with anti-vibration joints, when assembly is completed they should not be taut,
so as to avoid damage and the transmission of vibrations.
To ensure the seal of the connections and the integrity of the machine, it is essential that the air ducts be
supported by special brackets that do not weigh directly on the machine.
