DUCT COLLARS

standard basement and attic installations (fully ducted)

Use the screws in the parts bag to attach the duct collars to the inlet and outlet of the dehumidifier. The outlet collar has a backflow damper.

The outlet duct collar may be attached to the top or end of the unit. Move the outlet cover to the location not being used. See Figure 2..

Make sure there are no bends in the ductwork coming off the outlet for a minimum of 4”. This will ensure that the ductwork will not interfere with the backflow damper function..

closet installations

Use the screws provided in the parts bag to attach the duct collars if desired or required based on recommendations below:

Where inlet space is restricted, the inlet duct collar is optional.

When the dehumidifier is installed below the HVAC equipment and requires a vertical discharge, move the top access panel to the end of the unit.. The outlet duct collar with backflow damper is not required.. See Figure 3..

When the dehumidifier requires a ducted vertical discharge, remove the top access panel and remount on the outlet of the unit.. Install the outlet duct collar with backflow damper on top of the unit.. See Figure 3..
