Choose an appropriate location to install the exterior
hoods:
• There must be a minimum distance of 6 feet
between the hoods to avoid cross-contamination
• There must be a minimum distance of 18 inches from
the ground
!
Make sure the intake hood is at least 6 feet
away from any of the following:
• Dryer exhaust, high efficiency furnace vent,
central vacuum vent
• Gas meter exhaust, gas barbecue-grill
• Any exhaust from a combustion source
• Garbage bin and any other source of contamination
Refer to figure at right for connecting insulated ducts to
the exterior hoods. An "Anti-gust intake hood'' should be
installed in regions where a lot of snow is expected to fall.

recommended for climates where the outside temperature typically remains below -13°F, (over a 24-hour
period) for several days in a row, combined with an indoor humidity of 40% or higher.

Make a water trap loop in the tube to prevent the
unit from drawing unpleasant odors from the drain
source. Run the tube to the floor drain or to an
alternative drain pipe or pail.
IMPORTANT
If using a pail to collect water, locate the tube end
approximately 1" from the top of the pail in order to
prevent water from being drawn back up into the unit.
