3.3.2 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 insulation covering (minimum 4” (100 mm) mineral wool) with
plastic diffusion barrier. In areas with extremely low outdoor temperatures during the winter, additional
insulation must be installed. Total insulation thickness must be at least 6” (150 mm).
