SAFETY CONSIDERATIONS
Installation and service of heating and air conditioning equipment can be
hazardous due to system pressure and gas and electrical components. Only
trained and qualified personnel should repair, or service heating and air
conditioning equipment. Untrained personnel can perform basic maintenance
functions such as cleaning and replacing air filters. All other operations must be
performed by trained service personnel. When working on heating and air
conditioning equipment, observe precautions in the literature, tags, and labels
attached to or shipped with the unit and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth
for brazing operations. Have fire extinguisher available. Read these instructions
thoroughly and follow all warning or cautions attached to the unit. Consult local
building codes and National Electrical Code (NEC) for special requirements. It is
important to recognize safety information.

iNTRODUCTiON
The Model MAIC High Efficiency Air Cleaner isdesigned for installationinthe return=
air duct in any forced-air heating and/or cooling system. The model MAIC High
Efficiency Air Cleaners are available in two sizes, 0014 and 0020.
The FMC media filter isa mechanical air cleaner incorporating special pleated filter
media designed to remove dirt, dust, pollen, and other microscopic particles from
the air passing through it.The pleats provide an exceptionally filtering face area in a
very compact space which allows maximum dirt holding capacities.
When applying the MAIC, attention must be given to duct and system design
because these components affect system static pressure. To maintain the proper
efficiency and reliable operation of the MAIC Mechanical Air Cleaner and your
HVAC equipment, this filter should only be applied to properly designed duct
systems and properly sized HVAC equipment. The MAIC has a higher static
pressure drop than the typical factory supplied furnace and/or fan coil filter (See
Typical Pressure Drop Table).

APPLiCATiON
The air cleaners are used in forced air heating, cooling and ventilating
systems. The air cleaner should be installed in the system so that all the
system air is circulated through the air cleaner. The air cleaner will only
remove the airborne contaminants delivered to it. Maximum performance
isobtained when the system blower is 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 is
required, refer to section entitled Transitions. The unit must be readily
accessible for periodic inspection and replacement of media cartridge to
maintain maximum efficiency and trouble-free operation.
Air Conditioning.
The air cleaner should be installed upstream of the cooling coil. This will
keep the coil clean and reduce air conditioning coil maintenance.
improved cooling efficiency is the result which directly affects energy
costs. A clean coil will reduce utility costs. Failure to replace media can
cause damage to 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

Turning Vanes
Ifthe 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 (Figure 3).

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 humidifiers
should be installed downstream of the air cleaner. If the humidifier
must be installed upstream, allow at least 6 feet between the
air cleaner and humidifier.

SELECT LOCATION FOR THE AiR CLEANER
Select a location that is readily accessible for periodic inspection and
cleaning. Allow a minimum of 26" in front of the access panel for filter
removal. For complete dimensions required, refer to the section entitled
SPECiFiCATiONS.
DiRECTiON OF AiR FLOW THROUGH THE AiR CLEANER
The air cleaner isset 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.
PHYSICAL iNSTALLATiON
The air cleaner can be in any position, except with the access door
facing down. The section entitled TYPICAL MOUNTING POSiTiONS
(page 5) shows proper air cleaner mounting with a variety of furnace
installations.
CUT HAZARD
Failure to follow this caution may
result in personal injury.
Sheet metal parts may have sharp
edges or burrs. Use care and wear
appropriate clothing, safety
glasses and gloves when handling
parts and servicing equipment.
ELECTRIC SHOCK HAZARD
Failure to follow this caution may
result in personal injury or death.
Before installing, modifying or
servicing system, turn OFF the
main (remote electrical disconnect
device. There may be more than
one disconnect device.
Prior to installing this product...
1. Check the ratings given on the product to make sure it is suitable for
your application.
2. Remove the old furnace filter and discard.
3. The air cleaner cannot remove existing dirt from the blower and
ducts.
8
NOTE:
Thefollowingis a typical installation of the air cleaner on a high boy
furnace. You may have to alter the installation to fit your specific
application.
5. Locate the cabinet in the cold air return duct so that all of the return
air flows through the unit. If the furnace and air cleaner openings are
different, use atransition (see Figure 2).
6. Mounting holes are provided for
simple connection to duct work.
The .140" holes are sized for #8
sheet metal screws, or 1/8" rivets. If
the adjoining duct work is flanged,
install the screws so that the screw
heads are inside the cabinet. This
will prevent damage to the filter
cartridge during removal and
installation (Figure 4).
7. Remove media filter cartridge from
plastic bag and replace media
filter in cabinet.

8. After the unit has been secured, seal seams air tight with duct tape
or caulking. Reinstall access door to ensure atight seal.

HOW TO MAINTAIN YOUR AIR CLEANER
The filter in your air cleaner must be replaced periodically. The frequency
of filter replacement is best determined by visual examination. On
average, media filters should be replaced every 6-12 months under
normal usage.
STEPS FOR REPLACING FILTER
1. Open access door by pulling the handle. Remove door completely.
2, Pull used filter straight out of cabinet and disassemble and discard
3, Remove new filter cartridge from box and assemble,.
4, Slide new filter cartridge into cabinet with "AIR-FLOW" arrow pointing in
the direction of air flow.
5. Replace door.
Replacement Cartridge Filters For Your Media Air Cleaner
Remember, periodic inspection and annual replacement of your filter will
insure high efficiency air cleaning. Contact your HVAC dealer for
replacement filter cartridges.
