Introduction
Your media air cleaner is a high efficiency air filtration device designed
to remove dirt, dust, pollen and other microscopic particles from the air
passing through it. Considering the messy dirt collecting job it
performs, you will be pleased with the simplicity of its operation and
care.
How the Air Cleaner Works
Dirty air enters the air cleaner by way of the return air duct system in
your home. Particles are collected by the special pleated filter media.
The pleats provide an exceptionally large filtering face area in a very
compact space which allows maximum dirt holding capacities with
minimum air flow resistance.

How to Maintain Your Air Cleaner
The media filter cartridge in your air cleaner must be replaced
periodically. The frequency of filter replacement is best
determined by visual examination. On average, filter cartridges
should be replaced every 9-12 months with normal usage.
STEPS FOR REPLACING FILTER CARTRIDGE
1. Open access door by pulling the handle. Remove door
completely.
2. Pull used filter straight out of cabinet and place to side.
3. Remove new filter cartridge from plastic bag and save the
bag.
4. Slide new filter cartridge into cabinet with “AIR-FLOW”
arrow pointing in the direction of airflow.
5. Replace door and place used filter in plastic bag for easy
disposal.
Replacement Filter Cartridges For Your Media Air Cleaner
Remember, periodic inspection and replacement of your filter
will ensure high efficiency air cleaning. Contact your HVAC
dealer for replacement filter cartridges.

Physical Installation
The air cleaner can be installed in any position, except with the access door
facing down. The section entitled Typical Mounting Positions shows
examples of proper air cleaner mounting with a variety of furnace
installations.
Prior to installing this product . . .
1. Read rules and instructions carefully for safe operation. Failure to follow
them could damage the product or cause a hazardous condition.
2. Check the ratings given on the product to make sure it is suitable for
your application.
3. Remove the old furnace filter and discard.
4. The air cleaner cannot remove existing dirt from the blower and ducts.
Clean the area thoroughly before beginning installation.
NOTE:
The following is a typical installation of the air cleaner on a highboy furnace.
You may have to alter the installation to fit your specific application.
5. Locate the cabinet in the cold air return duct such that all of the return
air flows through the unit. If the furnace and air cleaner openings are
different, use a transition.
6. Mounting holes are provided in the air cleaner cabinet for ductwork
attachment. The .140” diameter holes are sized for #8 sheet metal
screws, or 1/8” rivets. If the adjoining ductwork is flanged, install the
screws with the screw heads inside the cabinet, to prevent damage to
the filter cartridge during removal and installation.
7. Remove the plastic bag from the filter cartridge and replace filter
cartridge in cabinet.
8. After the unit has been secured, seal seams air tight with duct tape or
caulking. Reinstall access door to ensure a tight seal.

Tur ning Vanes
If the air cleaner is installed adjacent to a 90° duct elbow,
add turning vanes inside the duct to improve the air
distribution across the face of the air cleaner.
Direction of Air Flow Through the Air Cleaner
The air cleaner is set up for left to right air flow, when
facing the access door. For right to left air flow remove filter
cartridge, turn it around and replace in cabinet. The
directional arrows on the filter cartridge must point in the
direction of air flow.
Humidifiers
Location of the system humidifier is important to the
operation of the air cleaner. When an evaporative type
humidifier is used, it may be installed between the furnace
warm air duct and the return air duct without effecting the
air cleaner. Atomizing and spray type humidifiers should be
installed downstream of the air cleaner. If the humidifier
must be installed upstream of the furnace, allow at least 6’
between the air cleaner and humidifier.

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. The air cleaner will only
remove the airborne contaminants delivered to it; therefore 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. The unit must be readily accessible for periodic inspection and
replacement of the filter cartridge to maintain maximum efficiency and
trouble-free operation. Allow a minimum of 26” clearance in front of the
access panel for filter cartridge replacement.
Air Conditioning
The air cleaner should be installed upstream of the cooling coil to keep the
coil clean and reduce air conditioning coil maintenance. A clean coil will
reduce utility costs by maintaining the coil’s efficiency. Failure to replace
filter cartridge can cause damage to the cooling system.
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.
