Enhanced Safety

Integrated safety features, such as the thermal fuse, provide added protection against risks such as elevated exhaust temperatures that could cause overheating.

Some helpful tips for installing the DEDPV 705:

  • Do not use rigid PVC pipes or flexible ducts. Use only steel or aluminum ducts rated for dryer use. These ducts have smooth walls, so lint is less likely to build up.

  • If running the dryer duct through an unconditioned space, wrap it in insulation. If the duct stays warm, it will be less likely to form condensation and collect lint.

  • To avoid clogging lint over the exhaust fan impeller, install a DBLT 4W (#46000) secondary lint trap (not suitable for gas dryers) between the dryer and the DEDPV-705. This lint trap filters the air and catches the lint, thus protecting the product and the ductwork. The less lint accumulation, the better the dryer performs.

  • Add the DEDPV-705 to the dryer exhaust 4-inch duct system only when the equivalent duct length is between 25 feet and 125 feet. For each 45° elbow, add 2–1/2 feet to your total duct system calculations. Add 5 feet for every 90° elbow.
