Before installation (continued)
Application Considerations:
The SecureAire Air Purier is designed to work with gas, oil, and electric forced air furnaces and central air
conditioning systems.
Airow considerations are vital to the heating and cooling system’s performance, longevity, and safety, as
well as the performance of the SecureAire Air Purier. Industry standards are established to ensure
proper design and installation of this product and the associated ductwork.
Choosing a Mounting Position:
The SecureAire Air Purier mounts in any position within the return air duct, usually next to the furnace
blower compartment. There are directional arrows on the lter to conrm proper cabinet location. See
below for proper locations for the SecureAire Air Purier in a variety of furnace and air handler installations.
Type Description
1Upow with side install. The SecureAire Air Purier
is mounted vertically where return enters side inlet
of furnace.
2Upow with install beneath furnace. The SecureAire
Air Purier is mounted horizontally where return
enters from below.
3Upow with closet install. The SecureAire Air Purier
is mounted vertically on furnace between furnace
and louvered return air opening in closet door.
4Counterow with the SecureAire Air Purier is
mounted horizontally in return plenum just above
furnace and opposite heating plenum.

Installing the SecureAire Air Purier: Upow Furnace Example
The following procedure describes a typical installation on an existing upow 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 lter (if used).
Thoroughly clean the blower compartment. EPA recommends a professional duct cleaning whenever the
system’s normal airow will stir up and circulate dust or debris into the treated indoor environment.
https://www.epa.gov/indoor-air-quality-iaq/should-you-have-air-ducts-your-home-cleaned.
WARNING
Electric Shock Hazard!
Can cause personal injury!
Do not, under any circumstances, use an electrical extension cord
other than the 8-foot cord provided with the unit.
Before installing or servicing this system, always make sure that the
main power to the system is turned o. There may be more than one
electrical disconnect switch.
The Step-by-Step Installation Process
Step 1: Review the installation plan and airow direction
Temporarily place the SecureAire Air Purier on the oor, orienting as it will be when installed.
Temporarily insert and remove the SecureAire Air Purier to make sure there is adequate clearance
for easy removal if that is ever necessary.
If the installation of the unit requires the airow direction to be reversed, this is easily
accomplished by removing the main assembly (Step 6) and rotating it into the proper
ow direction.

Installing the SecureAire Air Purier: Upow Furnace Example
Step 3: Pre-wire the power supply
(PRE-WIRE ONLY. DO NOT CONNECT TO POWER.)
Installation of the SecureAire Air Purier should be performed by a licensed electrician or a certied HVAC
technician. Electrical wiring must comply with applicable local codes and standards.
These are pre-wire instructions only. Power is not connected to the unit at this point.
Wire ring lugs must be used when connecting input line voltage to the terminal block. These are
supplied on the plug-in power cord supplied with the SecureAire unit.
If connecting directly from another source, the technician must install wire ring lugs on the power
wires that connect to the SecureAire terminal block.
The supply line voltage power source is 120V/60 Hz.
A. Remove the 2 (two) Phillips head lock screws from the cabinet’s top access panel.
B. If the existing wiring connection out of the
back of the power supply will be obstructed
when the unit is installed, additional
knockouts are provided on both sides of the power
supply. Remove the existing wiring strain relief and
relocate it if needed.

Installing the SecureAire Air Purier: Upow Furnace Example
E. Tighten the wiring strain relief on the outside of the power supply box.
F. Re-install the access panel with the 2 (two) lock screws.
Step 4: Connect the cabinet to the furnace or air handler
A. If needed, cut an opening in the equipment cabinet to match the SecureAire Air Purier’s cabinet or
provide a proper sheet metal transition from the cabinet to the equipment.
B. If necessary, place blocks under the SecureAire Air Purier to make sure the unit sits securely.
C. Connect the SecureAire Air Purier securely to the furnace. Fasten with sheet metal screws or use S-cleat
type slip joints. If you are drilling holes, use locking pliers to help hold the cabinet in place during drilling.
Step 5: Connect the cabinet to the return air plenum
A. If needed, install turning vanes to help distribute air equally over the full surface of the upstream side
of the SecureAire Air Purier.
B. Connect the SecureAire Air Purier securely to the return air ductwork. Fasten with sheet metal screws
or use S-cleat type slip joints. If you are drilling holes, use locking pliers to help hold the cabinet in place
during drilling.
C. Inspect the SecureAire Air Purier to make sure that no metal lings are lodged in the unit and the
cabinet is free of any debris.
C. Connect unpowered wire ring lugs as shown. D. When using the supplied plug-in cord, match the
cord wiring color to the same color wires on the
wiring terminal block.

Installing the SecureAire Air Purier: Upow Furnace Example
Step 7: Seal all sheet metal joints
Seal all joints in the sheet metal connections you made to prevent ambient air from entering or leaving
the ductwork. May use silicone sealant, mastic, or UL-approved sealant tape.
Step 8: Connect power to the power supply
Installation of the SecureAire Air Purier should be performed by a licensed electrician or a certied HVAC
technician. Electrical wiring must comply with applicable local codes and standards.
Wire ring lugs must be used when connecting input line voltage to the terminal block.
The supply-line voltage power source is 120V/60 Hz. When using the supplied plug-in power
cord, plug the cord into an accessible outlet. When connecting power through another source,
such as the equipment manufacturer’s provided EAC terminals, follow the equipment
manufacturer’s directions on how to make that connection.
Step 6: Reinstall the PlatinumPLUS Assembly
Reinstall the cartridge assembly making sure that the airow arrows are pointing in the desired
airow direction.

Installing the SecureAire Air Purier: Upow Furnace Example
Note: The SecureAire Air Purier may be wired to be on continuously, even without the system
fan being on, as there are no harmful byproducts, such as ozone, produced by this device.
Step 9: System Operation Check
A. With the door closed, turn on the SecureAire Air Purier with the ON/OFF switch. The switch will glow
with a green light indicating that the power supply is on and operating properly.
B. Turn o the SecureAire Air Purier and the ON/OFF switch light turns o, indicating the entire
SecureAire power supply is powered o. The SecureAire Air Purier is now safe to access.
Built-in User Safety — Opening the front door before turning o the SecureAire Air Purier will disable
the high voltage circuit and de-energize the entire device.
Congratulations!
The SecureAire Air Purier installation is complete.
