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.

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
words WARNING and
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.

LOCATION
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.
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.
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
