1.2.2. Unit types by duct connections

Depending on the installation and connection of the ducts, the air handling units are divided into: 

•  Vertical units

 (marked by the letter V) – when all ducts are connected at the top of the unit.

•  Horizontal units

 (marked by the letter H) – when all ducts are connected on the sides of the unit.

•  Universal units

 (marked by the letter U) – which duct connections can be relocated from the sides of the unit to the 

top and vice versa. Each universal unit has 16 different duct layout options that are easy to change during installation, 

depending on the intended installation location.

1.2.3. Unit types by inspection sides

Also, each unit may be left or right inspection side

1

. The inspection side indicates which side of the unit contains the air 

supply duct to the premises. The exact arrangement of the duct connections for the different inspection sides can be found 

in section “Unit components”.
