4.3.3 Air connections
Ductwork must have independent supporting devices.
ClimaPac unit cannot be used for supporting the Ductwork.
In order to avoid the transmission of noise to the structure, the connection between the ClimaPac and
duct-work must be free of tensions, using flexible duct connectors.
The length of the flexible duct connection once mounted must always be smaller than its maximum
length.
Dimensions of the duct connection frames are indicated in the technical sheet of the unit.
4.3.4 Fans
Plug fans with AC motors are mounted on anti-vibration springs. To avoid the fan to move during
transport and installation, 4 transport brackets are used to fix the fan structure to the steel support.
These brackets (in red in the following picture) must be removed before the first start-up of fans.
