Exhausting Requirements - Midea MLTE45N4BWW Service Manual

Service manual for Dryer Machine
11. 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.
12. The hood should have at least 12 inches (30.5cm) of clearance between the bottom of the
hood and the ground or other obstruction. The hood opening should point down.
13. Never install a screen over the exhaust outlet.
14. To avoid lint buildup, do not exhaust the dryer directly into a window well. Do not exhaust
under a house or porch.
15. If the exhaust duct 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.
16. Inspect and clean the interior of the exhaust system at least once a year. Unplug the power
cord before cleaning.
17. Check frequently to make sure the exhaust hood damper opens and closes freely.
18. Check once per month, and clean at least once per year. Note: If your clothes are not getting
dry, then check the ducting for obstructions.
19. Do not exhaust the dryer into a 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 the lint
expelled by the dryer.
20. Do not use non-metallic flexible duct.
21. To reduce the risk of fire, this dryer MUST BE EXHAUSTED OUTDOORS without obstruction
around the outlet.

3.3 Exhausting requirements

WARNING
The dryer shall not be exhausted into a chimney, a wall, a ceiling, an attic, a crawl space, or
-
a concealed space of a building.
The dryer must be exhausted to the outside to reduce the risk of fire when installed in alcove
-
or closet.
Exhausting the dryer to the outside will prevent large amounts of lint and moisture from being
blown into the room.
NEVER USE A PLASTIC OR NON-METAL FLEXIBLE DUCT
-
If your existing ductwork is plastic, non-metal, or combustible, replace it with metal.
-
Use only a metal exhaust duct that is non-flammable to ensure containment of the exhaust
-
air heat, and lint.
- Refer to the "Ducting requirements" section for the maximum duct length and number of
bends.
- All dryers must be exhausted to the outside.
- Do not assemble the duct with screws or other fastening means that extend into the duct and
catch lint.
- The exhaust duct should be 4 inches (102mm) in diameter.
- The total length of flexible metal duct shall not exceed 7.8 feet (2.4 meters).
