For relevant advice, pleasecontact Zehnder.• Install, the air ducts with a minimum ø of 125 mm,as little air resistance as possible and free from airleakage.• When using flexible channels only Zehnder chan-nel systems may be used. Any other fl exiblechannel will disturb the basic operating principleof the balanced ventilation system.• We recommend that the ventilation system be fi t-ted with intake and exhaust valves made by Zeh-nder.• Insulate the outside air supply and the air exhaustduct between the roof/wall passage to render theComfoAir damp proof. This prevents the forma-tion of condensation on the outside of the ducts.• The air exhaust duct must be fitted with a doub-le-walled or insulated roof passage. This preventsthe formation of condensation between the roofboarding. In addition, the air exhaustduct must drain in the direction of theComfoAir.• To prevent unnecessary temperature loss in eit-her the summer or the winter, we recommendfitting thermal and damp-proof insulation to thesupply ducts from the ComfoAir up to the supply-valves.
