General information and safety notes
Density limit diagrams
The following diagrams roughly demonstrate the relation between the amount of refrigerant
charged for the relevant R32 PACi or PACi NX outdoor units ([mc]) and the required minimum
installation space floor area.
AHU units
For the AHU units, the density limit diagram shows three different "Density Limit Lines", where each
line applies to a different AHU unit installation height and installation orientation (horizontal/vertical)
