Installation
Application
This air cleaner is used in forced air heating, cooling, and ventilating systems. The air cleaner should be installed in the system such that all the system air is circulated through the air cleaner. Maximum performance is obtained with the system blower set for continuous operation.
Installation Requirements
The best location for the air cleaner is in the return air duct next to the blower compartment. In this location, the blower motor and cooling coils will be kept clean. Do not install the air cleaner in the discharge air duct. Before installing the air cleaner, consider the application. If a transition between the ductwork and air cleaner is required, refer to section entitled Transitions, below. The unit must be readily accessible for periodic inspection and replacement of the filter cartridge to maintain maximum efficiency and
Transitions
If the air duct does not fit the air cleaner cabinet opening, gradual transitions are recommended to reduce air turbulence through the air cleaner and maximize efficiency. Not more than 20° (about 4” per running foot) of expansion should be used on each side of the transition fitting.
Maximum 4" drop per linear foot
