6.4.1.2 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 outdoor temperatures during the winter, additional insulation
must be installed. Total insulation thickness must be at least 150 mm.
Caution
• If the unit is installed in a cold place make sure that all joints are covered with insulation, and tape well
• Duct connections/duct ends should be covered during storage and installation
• Do not connect tumble dryers to the ventilation system
