SAFETY CONSIDERATIONS
Read and follow instructions carefully. Follow all local
electrical codes during installation. All wiring must
conform to local and national electrical codes.
Improper wiring or installation may damage the HEPA
Air Cleaner.
Understand the signal words WARNING and
CAUTION which are present in the Owner’s Manual.
WARNING and CAUTION signify a hazard which
could result in property damage, personal injury or
death.
Only a heating/air conditioning installer or qualified
service person should install, repair, or service
your Whole-House HEPA Air Cleaner.
Homeowners or untrained personnel can perform
the basic maintenance functions of replacing
filters.
When working on air cleaning equipment, observe
precautions in the Owner’s Manual, labels attached
to the unit, and other safety precautions that may
apply. Follow all safety codes. Wear safety glasses
and work gloves.
WHAT THE HEPA AIR CLEANER DOES
The Whole-House HEPA Air Cleaner has been
designed to remove particulate such as atmospheric
and household dust, coal dust, insecticide dust, mites,
pollen, mold spores, fungi, bacteria, viruses, pet
dander, cooking smoke and grease, tobacco smoke
and more. It also removes odors with the Carbon
Prefilter.
BENEFITS
 Helps provide relief from allergies, asthma, and
other respiratory illness.
 Helps reduce housekeeping time and redecorating
costs.
 Helps provide a healthier, more comfortable
environment, year-round.
HOW IT WORKS
Millions of airborne pollutants are carried through the
return air ducts of the heating/cooling system. The
HEPA Air Cleaner has been designed to be ducted to
the return air duct. A portion of this return air is by-
passed through a 8 inch intake duct on the unit and
passes through a 2-stage filtration system.
The Activated Carbon Prefilter (activated carbon
impregnated polyester filter) first removes lint and
odors before they enter the HEPA filter.
Smaller particles then pass through a long-life, HEPA
(High Efficiency Particulate Air) Filter which captures
99.97% of particles 0.3 micron (1/84,000 of an inch)
and larger. This HEPA filter has more than 65 ft² of
collection surface area.
Clean air is discharged through a 6 inch duct, back into
the return air duct.
INSTALLATION
LOCATION
The HEPA Air Cleaner should be located as close to
the return air duct as possible. This allows for shorter
lengths of ducting which helps keep the static pressure
lower. The unit can be adapted to mount on a wall or
be suspended from the ceiling. Care should be taken
to keep the unit away from an area where there is a
possibility of moisture leaking on to it. Ensure there is
24-36 inches above the unit to remove the filters for
cleaning or replacing.
GENERAL INSTALLATION STEPS
1. Remove any packaging or plastic from filters
before installing. See Maintenance for instructions
to remove the filters.
2. When the unit is shipped, the intake and exhaust
collars are reverse mounted to prevent damage in
shipping. Both collars must be removed and
reattached with the collar ring facing out.
3. An inlet collar is provided on the unit to allow a
flexible 8 inch intake duct, from the cold air return,
to be attached. The 8 inch intake must be drawn
from the cold air return duct at a location that will
be ahead of the clean exhaust air, that will be
returned to the duct from the Air Cleaner.
WARNING
Before beginning any installation or modification, be
certain that the main line electrical disconnect switch
is in the OFF position. Electric shock could result. Tag
disconnect switch with suitable warning labels.
WARNING
This unit must be installed on the return air side of
the system only. Do not connect to supply side.
Do not install in a cooking area or connect directly to
any appliance.

4. A duct adapter and a length of 8 inch flexible hose
or duct is required to attach between the 8 inch
intake collar and the existing cold air return duct.
When running the hose, make sure that there are
no kinks or sharp bends that will impede the air
flow to the unit. Secure and seal the hose and
connections to prevent air leakage.
5. A duct adapter and a length of 6 inch flexible hose
or duct is required to attach between the exhaust
collar and the existing cold air return. The exhaust
hose should be attached to the return air duct,
close to the furnace. The ideal location is low on
the return air boot pointing at the furnace. To
prevent air shear inside the duct, it is
recommended that you install a deflector inside the
boot, so the discharged air is deflected down into
the boot. When running the hose, make sure that
there are no kinks or sharp bends that will impede
the air flow from the unit. Secure and seal the
hose and connections to prevent air leakage.
6. It is important to maintain some distance between
the intake and the exhaust openings in the return
air duct. Failure to do this may result in short
cycling between the intake and the clean air
discharge. It is recommended you leave 10 feet
between the intake and the exhaust; however, as
little as 6 feet will work effectively. If the distance is
smaller than 6 feet, it is important that an air
deflector is installed in the duct.
7. If outside air is introduced into the return air duct,
either through a HRV (Heat Recovery Ventilator) or
direct, it should be added to the system before the
intake inlet to the Air Cleaner.
OPERATING INSTRUCTIONS
The HEPA Air Cleaner is designed to run continuously
to provide clean, filtered air 24 hours a day. The fan on
the heating/cooling system, to which the HEPA Air
Cleaner is dependent on for circulated air, should be
on ‘continuous’.
Note: If the system fan setting is on ‘automatic’, it is
recommended the HEPA Air Cleaner be operated
through an air switch or relay to turn the Air Cleaner
off, when there is no system fan on.
The unit plugs into a regular 120 volt outlet and is
controlled by a switch located on the rear panel, near
the cord.
Note: Do not allow the cord to be placed where it
may be walked on or allow anything to roll over it.
The top cover must be secured for the Air Cleaner to
operate. All filters must be in place for the unit to
operate properly.
MAINTENANCE
For efficient operation, the filters must be changed on a
regular basis. If you notice a reduction in air flow from
the system, check the filters.
1. To access the filters, turn the Air Cleaner OFF at
the switch and remove the top cover.
2. Release the filter hold down bar by pulling it
forward one side at a time.
3. Carefully remove filters to avoid spilling of collected
contaminants. Dispose of filters in a plastic bag
and discard with regular household trash.
4. Remove plastic from new filters before installing.
Discard plastic safely. Take care not to damage the
filters.
5. Date the replacement filter in the space provided.
6. Place the Carbon prefilter around the HEPA filter
and secure with the Velcro.
7. Ensure the open end of the HEPA filter is toward
the motor.
8. Replace the filter hold down bar by placing one
side under the bracket on the side of the cabinet.
Once you have one side started, force the bar
under the bracket on the other side of the cabinet.
This ensures the filter has a good seal.
9. Use genuine replacement filters only. Call the
original installer for parts.
Note: When the filters are new, you may notice a
new smell from the system. This is normal and will
dissipate within a few days.
Carbon Prefilter (Part #W3-0855): This must be
replaced every 3 - 6 months and may be vacuumed
between changes. Use a soft brush attachment when
cleaning. If there are heavy odors in the home from
cooking, smoking, painting or other sources, the filter
will require changing more often.
True HEPA Filter (Part #W3-0840): Replace every 2-
3 years. The life of this filter depends on the amount of
contaminants in the air and the frequency in which the
prefilter has been changed. Renovations in the home
that create wood, drywall dust or similar contaminants
will shorten the life expectancy of the HEPA filter. To
improve airflow, the HEPA filter can be vacuumed
between changes, preferably outdoors. Use a soft
brush attachment for vacuuming this filter.
Note: Handle the HEPA filter by the frame only.
The paper is fragile and a puncture or tear will reduce
efficiency.
VOC After Filter (Part #W3-0810 optional): This
filter is positioned inside the HEPA filter, and must be
replaced every 6-12 months. If there are heavy odors
in the home from cooking, smoking, painting or other
sources, the filter may require changing more often.
WARNING
Never use the unit without all of the filters in place.
CAUTION
Make sure to turn Air Cleaner OFF before
performing any maintenance or removing any
components.
