Ducting Requirements - Samsung DC68-03021F-06 User Manual

DUCTING REQUIREMENTS
Use a 4-inch (10.2 cm) diameter rigid aluminum or rigid galvanized steel duct.
Do not use a smaller duct.
Ducts larger than 4 inches (10.2 cm) in diameter can result in increased lint accumulation.
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.
Only a rigid or flexible metal duct should be used for exhausting.
Keep the exhaust duct as straight and short as possible.
Secure joints with duct tape. Do not use screws.
DO NOT EXHAUST DRYER INTO ANY WALL, CEILING, CRAWL SPACE, OR CONCEALED SPACE OF
A BUILDING, GAS VENT, OR ANY OTHER COMMON DUCT OR CHIMNEY.
THIS COULD CREATE A FIRE HAZARD FROM LINT EXPELLED BY THE DRYER.
Do not use plastic flexible duct. 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
entry of wildlife. Never use an exhaust hood with a magnetic damper.
The hood should have at least 12 inches (30.5 cm) of clearance between the bottom of the hood and
the ground or other obstruction. The hood opening should point down.
Never install a screen over the exhaust outlet.
To avoid lint buildup, do not exhaust the dryer directly into a window well. Do not exhaust under a house
or porch.
If exhaust ductwork must run through an unheated area, the duct should be insulated and slope slightly
down towards the exhaust hood to reduce condensation and lint buildup.
Inspect and clean the interior of the exhaust system at least once a year. Unplug the power cord before
cleaning.
Check frequently to be sure the exhaust hood damper opens and closes freely.
Check once per month, and clean at least one time per year. Note: If clothes are not getting dry, then
check ducting for obstructions.
