4.7.1.2 Condensation and Heat Insulation
Outdoor air duct and discharge ducts must always be well insulated against condensation. Correct insulation installation
on ducts connected to the unit is especially important. All ducts installed in cold rooms/areas must be well insulated.
Use insulating covering (minimum 100 mm mineral wool) with plastic diffusion barrier. In areas with extremely low out-
door temperatures during the winter, additional insulation must be installed. Total insulation thickness must be at least
150 mm.
