2.4.3 S I
IMPLIFIED NSTALLATION
The central forced-air system blower must always be in operation when the unit is running since fresh air
evacuation and distribution come from the same section. The central forced-air system blower must operate
to avoid fresh air to be directly drawn by the evacuation, which would reduce signifi cantly fresh air supply
to the building.
Do not connect the unit to any forced air system supply duct.
Duct connection to the central forced-air system can be regulated by some codes and standards. It is your
responsibility to consider and comply with your local requirements to avoid any non-compliance.
Fresh air and exhaust air fl ow through the central forced-air
system ducts, which simplifi es the installation.
The use of bathroom fans and a range hood is suggested to
exhaust stale air.
S :
TALE AIR FROM BUILDING
Connect the stale air intake port of the unit to the central forced-
air system return duct at least 3 feet ahead of the fresh air
distribution from the unit.
F :
RESH AIR TO BUILDING
Connect the fresh air distribution duct of the unit to the central
forced-air system return duct at least 10 feet away from the
central forced-air system (A+B)*.
* This 10-ft. distance applies only in areas where the outside
temperature falls below the freezing point 0°C (32°F).
NOTE: A home with multiple forced air systems should have one
unit on each system.
