9.5 Insulate the ducts
Insulate outdoor and exhaust air ducts against condensation. All ducts installed in cold rooms/areas must be well insu-
lated. Use minimum 100 mm mineral wool insulation covering with plastic diffusion barrier.
Install additional insulation in areas with extremely low outdoor temperatures.
Caution
• Cover the joints with insulation and tape well if the unit is installed in a cold place.
• Keep duct connections/duct ends covered during storage and installation.
• Do not connect tumble dryers to the ventilation system.
9.6 Install silencer
Silencers are available as accessories at www.systemair.com.
Install silencers on both supply and extract air to avoid fan noise transference through the duct system.
Install silencer before every inlet diffuser to avoid noise transference between rooms.
