F100 MEDIA AIR CLEANER

Applications With Air Conditioning
Mount the media air cleaner upstream of the evaporator coil
in a cooling system. The filter will help to keep the coil clean
and reduce maintenance.
Applications With A Humidifier
The media air cleaner is compatible with humidifiers. Avoid
applications where water mist will reach the media. If an
atomizing humidifier is used, the filter media will require
replacement more often because of minerals in the water.
Choose Mounting Position
The media air cleaner can be mounted in any position, but the
arrow on the cartridge must point in the same direction as the
airflow. See Figs. 3-10 for proper location of the media air
cleaner for a variety of furnace installations. Note that the
media air cleaner cabinet is sturdy enough to easily support
the weight of the furnace and evaporator coil. See Fig. 4.

Replacement Media:
For optimum system performance, replace the filter every six
months (before heating season and before cooling season).
Adjust the schedule to you needs, but replace the filter at
least annually.

PLANNING THE INSTALLATION
Location
The media air cleaner should be installed where all the air
passing through the system is circulated through it. The best
location is in the return air duct next to the blower
compartment so the media air cleaner can help to keep the
blower motor and evaporator coils clean. Do not mount in the
supply air duct.
For most efficient air cleaning, spread airflow evenly across
the face of the media. If the duct is a different size than the
media air filter cabinet, gradual transitions are required. If the
duct turns sharply just before the air filter, turning vanes are
required.
Choose a location that is readily accessible for checking and
replacing the filter. Allow at least 26 in. (660 mm) clearance in
front of the unit for removal of the cartridge.
Install the media air filter where the temperature will not
exceed the ratings in the Specifications.
