FACTORS TO CONSIDER WHEN SELECTING UNIT LOCATION:
The installation must be done in the basement or the lowest, wettest, coldest level of your
dwelling. Try to find an outside wall to accommodate a 6¼” exit to the exterior of the
house where no electrical wires or pipes are present Minimum distance to any source of
heat should be
8 feet. Make sure that you do not install the unit in a boiler room.
FOR INTERIOR WALL INSTALLATION: The distance between the Sensor Control
BT back and the exterior wall should not be more than 12 feet. For this application the
flex has to be replaced with rigid piping.
Also maximize the distance between the unit and the source of replenishment air (example:
stairwell or openings to upper level).
SELECT DUCT HOLE LOCATION:
Now that you’ve decided where to install the unit, you must select a location for a 6¼” duct
hole in the outside wall. This hole is needed to pass a duct through the outside wall. Make
sure that the hole location is above ground level. Also make sure that the hole doesn’t line up
with a stud, electrical wires, or pipe. For the Sensor Control BT which is adjustable in height,
the hole is in the box/rim joist between the floor joists of the basement ceiling, or through the
wall.
Duct has to be dedicated and not combined with any existing ductwork that
is in operation.
CUTTING THE OPENING FOR THE DUCT
DRILL THE DUCT HOLE:
A).
From the
inside
, drill a
pilot hole of
approximately ¼” at the
center of the proposed 6 ¼”
hole.
If the ceiling is finished then drill a 6 ¼” hole in the ceiling between the floor joist about ½”
from the wall. Then follow the steps for cutting the 6 ¼” hole to the exterior.
