Installation
Turning Vanes
If the air cleaner is installed adjacent to a 90° duct elbow, add turning vanes inside the duct to improve the air distribution across the face of the air cleaner.
Direction of Air Flow Through the Air Cleaner
The air cleaner is set up for left to right air flow, when facing the access door. For right to left air flow remove filter cartridge, turn it around and replace in cabinet. The directional arrows on the filter cartridge must point in the direction of air flow.
Humidifiers
Location of the system humidifier is important to the operation of the air cleaner. When an evaporative type humidifier is used, it may be installed between the furnace warm air duct and the return air duct without affecting the air cleaner. Atomizing and spray type humidifiers should be installed downstream of the air cleaner. If the humidifier must be installed upstream, allow at least 6 feet between the air cleaner and humidifier.
