For integrated system installation
• Verify clearance on the ductwork to mount the unit using the Forced
Air heating/cooling system
• Minimum clearance requirements for maintenance and service
• Electrical power requirements
• Interaction between the HEPA lter unit and other mechanical
devices.
The Whole House HEPA unit is a versatile appliance with multiple
installations conguration. It is recommended to take your time in
planning the installation.
Several Installations are illustrated herein’ for Whole House ltration
applications:
• Return to return integrated with the forced air heating/cooling
system.
• Central draw points using dedicated duct system
Types of Intsallation
I. RETURN TO RETURN INTEGRATED SYSTEM
DUCTING FLAIR SYSTEM
Installation
The Whole House HEPA Filtration system is
designed to install directly onto the return
air plenum of the forced air heating/cooling
system. Choosing this type of installation
eliminates the need to externally duct the
HEPA lter unit to the plenum system. If
you choose this type of installation, it is
recommended that you run the fan on your
forced air system continuously to maximize its
cleaning ability.
COLLAR MOUNT SYSTEM
Installation
Whole House HEPA Filtration system can
be converted to use 8 inch round collars for
application requiring ducting. The kit includes
two, 8 inch round collars, two mounting
brackets for wall or oor mounting, installation
guide and fasteners.
Tips to installer
The Whole House HEPA Filtration
system does not replace the lter
from the forced air heating/cooling
system. Regular maintenance of
this lter is necessary to permit
the good operation of the forced air
heating/cooling system.

Consult your HVAC product manufacturer if the usage of this product will affect the performance of your forced air heating / cooling system.
II. STAND ALONE SYSTEM
ATTIC INSTALLATION
Ideal for homes without a forced air heating
/ cooling system. Allows for air ltration and
circulation throughout the home.
HEPA system must be operated continuously whenever a part or all the
system is located in an unconditioned space to avoid condensation in the
ductwork below freezing (0°C, 32°F).
BASEMENT INSTALLATION
Ducting will usually consist of one return
with grille from one side of the home, and
one supply with grille at the opposite end of
the home.

Once the holes are made in the main return duct
and the unit is aligned, the installer just has to
unfold the «Ducting Flairs» and screw the unit in
place.
STEP BY STEP INSTALLATION
Steps involved in the preparation of the plenum mount system are as followed:
Step 1
Preparing return air plenum
Find a location that satises both service and maintenance requirements and proceed to cut holes as
illustrated below.

The unit should look like this
when the foam piece is remvouved.
Tips to installer
It is recommended that the ltration unit
have a devoted receptacle with 120V.
It is not recommended to connect unit
with an extension cord. If no receptacle
is available please call an electrical contractor to have one installed.

Apply plenum seal tape all around both openings on the back of the unit. Bend tabs outward approximately 90 degrees.
Step 3
Mount Hepa
Align unit into place. Unfold the ducting airs completly to sandwich the return air plenum between the
ducting air and the ltration unit. Install unit as usual using all supplied fastening hardware.

FUNCTION
The Whole House HEPA system is comprised of
a ventilator, speed selection switch,
3 stages of ltration and the cabinet enclosure
system. The ventilator pulls air through the
pre-lter and then threw the impregnated carbon
pad for odor control and nally the last stage
of ltration is the HEPA lter which removes
99.97% of particles 0.3µm in size.
OPERATION MODE OPTIONS
The unit features two speeds of operation for
your convenience. The speed selection switch
is located on the front of the motor assembly.
At lowest speed the unit will provide 220 CFM
of clean air while at highest speed, the unit will
provide 300 CFM of clean air. It is recommended
that the unit be operated on highest speed
at all times to maximize the benets of the
HEPA ltration system. If for some reason the
ltration needs are not
as important then one
might operate the unit at
low speed.
An access door is
provided at the front
of the unit to permit
access to the lters and
speed selection switch. Opening the latch on the
right side of the unit will permit the door to swing
open. A safety door interlock switch cuts the
power to the motors for your safety. If needed
the door can be removed from the cabinet hinges
by holding the top part of the door with one hand
and gently taping on the bottom edge of the door
with the other hand to release the door from its
hinges.
Replace door and insert power
cord into the receptacle of the
lter units and the other end into
wall outlet.
RECOMMENDED OPERATION
The return plenum mount model operates
in conjunction with your forced air heating/
cooling system. A forced air distribution system
continuously circulates the same air inside your
home. The whole house HEPA ltration system
operates on the principal of bypass ltration,
which means that a portion of the air being
returned into the furnace is ltered on each
pass. Over time all the air in the home gets
cleaned. It is recommended that the furnace
blower be in operation whenever the ltration
system is in operation.
For stand-alone attic installation, the HEPA
ltration system must be operated continuously
whenever a part of all the system is located in an
unconditionned space to avoid condensation in
the ductwork below freezing (32°F ,0°C)
Maintenance of the unit should be performed at
regular interval to keep the benets of the HEPA
ltration unit.
