Location
This air cleaner is adaptable to unitary residential forced air
heating or cooling systems. It is designed to be installed in the
return air duct close to the blower compartment of the furnace
or air handler. This location provides the most even air flow
across the filter helping to keep the system motor and fan clean.
Installation
WARNING!
Turn off the heating and cooling system fan before performing
maintenance to the air cleaner.

Installation
IMPORTANT: This air cleaner may cause more of a restriction on the
airflow in the air-handling system than a standard 1" equipment filter,
because of its increased efficiency. As the filter collects particulates,
the pressure drop increases and airflow through the filter decreases.
This air cleaner is not recommended where added pressure drop would
cause operational problems with the heating and cooling equipment.
7.5
To improve the performance of the air cleaner,
these simple steps are recommended:
• Run your heating/cooling system fan continuously, on low
speed if available, since the air cleaner only removes particulate
matter when the system fan is operating.
• Ensure there are no obstructions to airflow (for example, from
furniture or carpets) in front of the return air grilles so that air
moves freely to the heating/cooling equipment.
Storage of Replacement Room Temperature Catalyst Insert
and MERV 15 filter
• Keep away from any chemical (solvents and strong oxidizers).
• Keep away from heat sources.
• Prevent dust generation
• Store in well-ventilated area.
• Keep the package tightly closed and away from dampness
and humidity.
Disposal of Replacement Room Temperature Catalyst Insert
and MERV 15 filter
• Dispose of in accordance with national, state and local regulations.
Disposal requirements are dependent on the hazard classification
and will vary by location and the type of disposal selected.
• Do not contaminate the ground or water with waste; do not
dispose of waste into the environment.
General Installation Steps
1. Remove existing equipment filter (if present) and clean
blower compartment: Thoroughly clean the blower
compartment, since the air cleaner cannot remove accumulated
dirt from the blower chamber and distribution ducts.
2.
Leave sufficient room around the air cleaner: There must be
adequate room to remove and replace the filter from the air
cleaner cabinet.
3. Transitions: If the air duct does not fit the air cleaner
opening, a gradual transition is recommended to reduce air
turbulence through the air cleaner and ensure its efficient
operation. A maximum of 20° of expansion, or approximately
4 inches per running foot (10 cm per 30 cm), is
recommended for each side of the transition fitting.
Note: Do not reduce ductwork size to fit a smaller air
cleaner. This will increase the velocity of airflow and may
decrease cleaning efficiency.
4. Turning vanes: If the air cleaner is installed adjacent to an elbow
or angle fitting, field-installed turning vanes are recommended to
improve air distribution across the filter.
5. Remove the door: When remov-
ing or replacing the door, hold the outer
door panel with both hands. The door
has industrial strength magnets in it
which can pinch fingers if caught
between door and cabinet.
6. Remove filters: remove filters (MERV 15
& RTC) from cabinet
7. Install the cabinet: Attach cabinet to
furnace and filter riser,
air handler or to
plenum with the ten
self-tapping hex head
screws provided. Note
direction of flow
indicated on top and bottom of cabinet.
8. Seal the joints in the return air system: All joints and seams
between the air cleaner, the heating / cooling equipment and the
return air duct should be sealed with aluminum tape or mastic to
prevent dust from entering the clean air stream.
9. Replace filters and door: After attaching cabinet and sealing all
joints, reinstall filters (note direction of flow). Reinstall door,
making sure it is properly seated. Remove plastic bag before
installing the room temperature catalyst (RTC) insert.
10. Adjust Daikin Badge: If a different orientation is needed, slide
badge up and pull out of door. Rotate to proper orientation
and reinstall.
