The following procedure describes a typical installation on an existing upflow furnace with a side return.
(Figure 1-1). Other changes in installation procedures may be necessary to complete your installation.
NOTE: Prior to beginning your installation, remove and discard the existing furnace filter
(if used). Thoroughly clean the blower compartment. EPA recommends a professional duct
cleaning whenever the system’s normal airflow will stir up and circulate dust or debris into the
home.

The Step-by-Step Installation Process
Step One: Review the installation plan and airflow direction
Temporarily place the SecureAire Air Purifier on the floor, orienting as it will be when installed.
Temporarily insert and remove the SecureAire Air Purifier to make sure there is adequate clearance for
easy removal if that is ever necessary.
If the installation of the unit requires the airflow direction to be reversed, this is easily
accomplished by removing the grid access panel (Step 3) and rotating it 180 degrees when
reinstalling it (Step 7).
