Important Installation Requirements
Failure to comply with these requirements
will result in voided warranty, improper
installation, and service callbacks.
Personal Safety
• Wear safety glasses while installing the unit.
• Do not cut into any air conditioning or
electrical line.
• Follow professional safety standards and
all local codes for plumbing, electrical, and
mechanical considerations.

Mounting the Honeywell Media Air Cleaner
STEP ONE: Review the Installation Plan
Temporarily place the cabinet on the floor, oriented as it will be when installed. Insert and remove the cartridge to make sure the
plan allows adequate clearance for easy removal and replacement of the cartridge.
STEP TWO: Fasten the Cabinet to the Furnace
a. Align the cabinet with the return air opening.
b. Place blocks under the cabinet, as necessary, to make sure the unit sits securely.
c. Create an opening in the furnace to match the cabinet opening.
d. Attach the cabinet securely to the furnace. Attach the unit directly or fit a starting collar in the furnace opening. Either drill
holes and fasten with sheetmetal screws or rivets, or use slip joints. If you are drilling holes, use a locking pliers to help hold
the unit in place during drilling.
STEP THREE: Install Turning Vanes
Install turning vanes to help distribute air equally over the full surface of the upstream side of the media. Install them whenever
an abrupt 90 degree elbow is installed directly against the media air cleaner cabinet.
STEP FOUR: Fasten Cabinet to Ductwork
Fasten side of cabinet to the ductwork using sheet-metal screws, rivets, or slip joints, as appropriate.
STEP FIVE: Connect Ductwork
a. Connect the vertical duct section to the elbow. If the vertical drop of the duct is less than 7 in. (178 mm) from the side of the
furnace, shorten the horizontal trunk or attach an offset fitting to the elbow.
b. When ductwork is properly aligned, connect the vertical duct to the horizontal trunk.
STEP SIX: Seal Joints
Seal all joints in the return air system between the media air filter and the furnace to prevent dust from entering the clean
airstream.
STEP SEVEN: Install Filter Cartridge
Slide the filter cartridge into the cabinet, making sure the arrow on the cartridge
points in the direction of air flow. Replace access door. Insert the tab on the bottom
of the door into the slot in the cabinet. Swing the door closed and press it into place.

QUICK START GUIDE
Application Considerations
Air Conditioning: Mount the media air cleaner up-
stream of the evaporator coil in a cooling system.
Humidifiers: The media air cleaner is compatible
with humidifiers. Avoid applications where water mist
will reach the media.
UV Lights: Germicidal UV lights can cause degrada-
tion of the media filter. The UV light should be located
out of line of sight or a minimum of 3 feet from the
filter.
Choosing a Mounting Position
The Media Air Cleaner mounts in any position within
the return air duct, usually next to the furnace blower
compartment, but the arrow on the cartridge must
point in the same direction as the airflow.
NOTE: The media air cleaner cabinet is sturdy
enough to easily support the weight of the
furnace and evaporator coil.
