Power Exhaust - Symbio Precedent 3 to 25 Tons - Installation Guide for Standard and Low Leak Economizer
Summary:
Power exhaust is designed for downflow applications¹. If the installation is for horizontal duct connections, the power exhaust may be mounted on the horizontal return duct. The installer is responsible for the installation. An economizer or motorized damper must be installed and functional before attempting to install the power exhaust. The power exhaust can be turned ON at infinite fresh air damper settings depending on how the unit is configured.
(1 Downflow application only is possible for units with low leak economizers.)
