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 odours with the Carbon
Filter.
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 installed
on the return air duct. A portion of this return air is by-
passed through an opening on the rear of the unit and
passes through a 3-stage filtration system.
The air passes through an efficient pleated MERV 11
Prefilter to remove lint and large particles to extend the
life of the HEPA filter.
The Activated Carbon Prefilter (activated carbon
impregnated polyester filter) removes odours before
they enter the HEPA filter.
Smaller particles then pass through a long-life, HEPA
(High Efficiency Particulate Air) Media Filter which
captures 99.97% of particles 0.3 micron (1/84,000 of
an inch) and larger. This HEPA filter has more than
40 ft² of collection surface area.
Clean air is discharged back into the return air duct.
INSTALLATION
Duct Mount Installation
LOCATION
The HEPA Air Cleaner can be installed directly on the
return air duct eliminating the need for external ducting.
The unit can also be mounted on the floor, a wall or be
suspended from the ceiling and with the use of collars
be ducted into the return air plenum. It can also be
used as a free standing unit. 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
13 inches in front of the unit to remove the filters
for replacing.
GENERAL INSTALLATION STEPS (Duct Mount)
1. Remove any packaging, as well as the door and
filters before installing. See Maintenance for
instructions to remove the filters.
2. If the unit is to be mounted on the return air
plenum, it must be installed after the last return
branch connection on the plenum. 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.
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.

3. Tape the mounting template level on the plenum
and proceed to cut and drill the necessary holes as
marked.
4. Cut the small joints on the mounting flaps on the
back of the unit as indicated. Bend all the flaps
outward slightly less than 90 degrees, except for
the upper bottom flap which is only bent up 45
degrees. This bottom flap will act as a deflector for
the exhaust air entering back into the plenum.
5. Place the gasket material around the two openings
on the back of the air cleaner. Place the unit on the
plenum so the flanges are placed through the holes
cut in the duct. Fold all the flanges, except the
upper bottom flap over, to enclose the duct
between the flanges and the unit. The upper
bottom flap is only bent up 45 degrees.
6. Secure the unit to the duct with the screws
provided.
GENERAL INSTALLATION STEPS (Collar Mount)
(Inlet collars are available as a kit from your distributor)
Collar Mount Installation
1. This unit can be installed with collars and flexible
ducting if desired. Openings are prepunched on
the top and bottom of the unit for this purpose.
Remove the plastic film over the holes and snip out
the joints to open the hole. Do not open the holes
in the back of the unit if you are collar mounting the
air cleaner.
2. The collar is installed with the flange on the inside
of the cabinet with only the collar ring on the
outside of the cabinet. Compress the collar until
you can insert the flange into the opening in the
enclosure. Enlarge the collar to its maximum and
install two screws into the ring to hold it to the
proper diameter. Turn the collar in the hole until the
holes in the enclosure line up to the holes on the
collar flange. Secure with the screws provided.
3. The intake collar on the return duct must be
installed after the last return branch connection on
the plenum. 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.
4. The 8 inch intake collar (top) must draw air from
the 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.
5. An 8 inch collar will be installed on the return duct
and a length of 8 inch flexible hose or duct is
required to attach between the 8 inch intake collar
and the collar on the 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.
6. The 8 inch exhaust collar can be mounted in the
same manner to the bottom of the unit. An 8 inch
collar will be installed on the return duct close to
the furnace and a length of 8 inch flexible hose or
duct is required to attach between the exhaust
collar and the collar on the return duct. 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.

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 bottom of the unit,
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 door 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 front door.
2. Carefully remove filters to avoid spilling of collected
contaminants. Dispose of filters in a plastic bag
and discard with regular household trash.
3. Remove plastic from new filters before installing.
Discard plastic safely. Take care not to damage
the filters. Hold by the frame only.
4. Date the replacement filter in the space provided.
5. Place the filters in their appropriate track with the
arrows pointing toward the fan.
6. 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 hours.
Prefilter (#DMH4-0855): This must be replaced every
3-6 months. A clean prefilter will increase the life of the
HEPA filter and improve airflow.
Carbon Prefilter (#DMH4-0810): This must be
replaced every 3 - 6 months. If there are heavy odors
in the home from cooking, smoking, painting or other
sources, the filter will require changing more often.
HEPA Filter (#DMH4-0400): 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.
Note: Handle the HEPA filter by the frame only. The
paper is fragile and a puncture or tear will reduce
efficiency.
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.
