INSTALLATION
Location —
The media air cleaner must be installed in the
return air duct, as close to the blower compartment as possible.
This location provides the most even airflow across the filter
and allows the media air cleaner to keep the system motor and
blower clean. See Fig. 3. When choosing location, there must
be adequate room to remove filters.
NOTE: Be sure to notify home owner not to install any device
within 3 ft from the side of the media air cleaner after installa-
tion is complete. Regular servicing of the media air cleaner is
required. A 3 ft clearance is required to remove filters for
maintenance or replacement.

INSTALLATION LOCATION WITH HUMIDIFIER — If
a separate humidifier is purchased, it should be installed in the
furnace warm air duct. However, a humidifier may be installed
in the return air duct without causing problems to the media air
cleaner. Care must be taken to ensure that the humidifier does
not leak, as this may cause damage to the media air cleaner and
mineral deposits on the filter.
An atomizing-type humidifier should only be installed
downstream of the media air cleaner. If the atomizing-type hu-
midifier is installed upstream, high humidity, salts, and miner-
als may damage the filter and cause service problems.
If the atomizing-type humidifier must be installed upstream,
the atomizing-type humidifier must be installed as far from the
media air cleaner as possible.
INSTALLATION LOCATION WITH AIR CONDI-
TIONER — Whenever possible, the media air cleaner should
be installed upstream of the cooling coil. This location will
clean the air before it reaches the evaporator coil.
Media Air Cleaner Installation —
Perform the fol-
lowing to install the media air cleaner.
1. Remove the existing furnace filter. Thoroughly clean
the blower compartment and ductwork where the
media air cleaner is to be installed.
2. Remove access door by unscrewing plastic knob. Slide
the filter out of the cabinet.
3. Place cabinet in ductwork. Holes are provided to
attach cabinet to ductwork or equipment. If the adjoin-
ing ductwork is flanged, install the screws so that the
screw heads are inside the cabinet. This will help pre-
vent damage to filters during removal for cleaning.
When the air duct does not fit the media air cleaner
opening, a gradual transition is recommended to
reduce air turbulence through the media air cleaner and
to increase its efficiency. There should not be more
than 20 degrees of expansion used on each side of
the transition fitting. Do not reduce ductwork to a
smaller media air cleaner or it will increase the veloc-
ity of airflow.
4. If the media air cleaner is installed adjacent to an
elbow or angel fitting, turning vanes are recommended
to improve air distribution across the filter.
5. After media air cleaner has been secured, seal seams
airtight with duct tape or caulking to prevent dust from
entering the system.
6. Replace filter. Make sure arrow on filter is pointing
towards the fan. Replace the access door.

IMPORTANT: The media air cleaner will cause
more of a restriction of your heating or cooling sys-
tem than a regular furnace filter due to its increased
efficiency. As the filter collects contaminants, the
pressure drop increases. The media air cleaner is not
recommended in systems where pressure drop is
critical. See Table 2 for pressure drop information.
