Lint accumulation should be cleaned regularly. • If a flexible metal duct must be used, use the type with a stiff sheet metal wall. Do not use a flexible duct with a thin foil wall. Serious blockage can result if the flexible metal duct is bent too sharply. • Never install any type of flexible duct in walls, ceilings, or other concealed spaces. • Keep the exhaust duct as straight and short as possible. • Secure joints with duct tape. Do not use screws. • Plastic flexible duct can kink, sag, be punctured, reduce airflow, extend drying times, and affect dryer operation. • Exhaust systems longer than recommended can extend drying times, affect machine operation, and may collect lint. • The exhaust duct should end with an exhaust hood with a swing-out damper to prevent back drafts and the entry of wildlife. Never use an exhaust hood with a magnetic damper. 14 English %7+2@&/64JOEE
