Due to the shape of the filter rack the access cover to the filter
can be placed on any of the four sides of the rack or duct.
When designing the air ducts consideration should be given
to the fact that the use of this accessory, always implies a
90° rotation of the dimensions of the unit's air inlet port,
as shown in the diagram below.
