Installation Requirements
The desired location for installation of an Ultravation® ProgressiveMedia™ Air Cleaner
is in the return air duct next to the blower compartment. In this location, the blower
motor and internal components will be kept clean. By installing the air cleaner in the
return (upstream from the cooling coils) the HVAC cooling coils in particular, will be
kept clean. This protection increases coil life, improving overall system efficiency,
saves power, and reduces maintenance costs.
Do not install this unit in the supply duct. Be sure to plan adequate space to allow fil-
ter replacement. Before installation is complete, seal all joints and seams airtight with
duct tape or caulking.
Once a ProgressiveMedia™ Air Cleaner is installed, it is very important to maintain the
unit by changing the filter periodically so as not to obstruct airflow, which can damage
components and increase energy costs.

Typical installation of an Ultravation ® ProgressiveMedia ™ Air Cleaner
ProgressiveMedia™ Air Cleaners have been designed for use with
virtually all types of HVAC systems.
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 degrees (about 4" per running foot) of expansion
should be used on each side of the transition fitting. (See diagram below)

Turning Vanes
If the air cleaner is installed adjacent to a 90-degree duct elbow, add turning vanes
inside the duct to improve the air distribution across the face of the air cleaner.
