REPLENISHMENT AIR TO BASEMENT FROM UPSTAIRS OF HOME
• The damp air exhausted by the Sensor Control BT must be replaced by the warmer/drier
air from the upper levels. If there is no open stairwell, the airflow is restricted from
coming down; then install a passive return grille with 100 sq. inches either in the door, in
the wall, or in the floor to allow unobstructed air downstairs.
• When the flow is limited or inaccessible between rooms downstairs (if there are walls or
partitions), then install a grille 8" x 10" in the bottom of the door or wall to avoid having
stagnant air in those areas. Otherwise interior doors must remain open. This insures that
all the air can be drawn into the Sensor Control BT from all areas of the basement.
• In the initial period after installation, before the Sensor Control BT has had time to dry out
the basement, and when the air outside is hot and humid; keep the doors and windows
downstairs closed to the outside. This will assure that the air is replenished with the air
from upstairs and not with the humid air from outside.
DUCTING
• Unit comes in two sections that allow for flexibility in positioning the duct at the most
convenient height. You can duct from the back of the unit, or from the top of the unit by
removing the top cover. Duct can go through an outside wall, the floor joist or window. Duct
should be vented above ground level to the outside or below ground into a window well that is
open and not sealed off to the outdoors. The outside louver should be high enough to avoid
infiltration of snow, flooding and rodents, etc. All necessary parts and outside louvers are
included.
• In case where the height clearance is too low, the top portion of the bottom section can be
cut down by a maximum of 40 inches with a cutter, leaving the vents at the bottom intact,
for a total minimum unit height of 62 inches.
•
Not more than one turn with the duct, and ductwork should not be longer than 3 feet in
total. When circumstances are that a longer span is required, then use rigid ducting from
the inside of the unit to the wall. The rigid duct will improve the airflow to compensate
for the additional distance the air has to flow to reach the outside.
• When replacing a pane for a window installation, use pressurized wood.
