operate
Unit should be synchronized with central forced-air system operation
to avoid condensation and mold growth in central forced-air system
distribution ducting if cooling mode of central forced-air system is used.
This configuration is not recommended with high velocity central forced-
air system. High pressures produced by these systems could affect unit
proper operation and generate errors.
NOTE: For this type of configuration, the T-3 option must be selected
on the LCD screen when auto-balancing the unit (see section 5.2).
2.2.3 S i
implified nStallation
The central forced-air system must be synchronized with the unit since fresh air evacuation and distribution come from the same section.
The central forced-air system must operate to avoid fresh air to be directly drawn by the evacuation, which would reduce significantly
fresh air supply to the building. See section 3.3 for ducting.
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 flow through the central forced-air system ducts,
which simplifies 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 (32°F).
NOTE: For this type of configuration, the T-4 option must be
selected on the LCD screen when auto-balancing the unit (see section 5.2).
