Dealer Installation Instructions

Forced air handler/furnace systems:
The HEPA system should be installed as a bypass system, with part of the
return ducted into the HEPA system. The filtered air is then rerouted back
into the return air, and continues through the system to be heated/cooled.
Typical Return to Return Application
For homes with upflow forced air handler/furnace systems.( Air handler/furnace
is shown in a typical basement.)
Distance between
A and B should
be 6' to 16' for
best results
NOTE: This filtration system is an ADDITIONAL filter, and does NOT replace the existing air handler/furnace system filter.
Preparation:
Here are some things to consider as you decide where to install the
HEPA system.
Location:
• Make sure there is room to open the HEPA filter access panel for filter
changes/inspections.
• Keep the HEPA system in a location where you can still access the air
handler/furnace filter.
• Keep the HEPAsystem away from possible water damage.
• Vibration pads will reduce vibration for installations where the unit is placed
on the floor.
• Install HEPA System on floor or suspended platform. If the unit is suspended,
screws must not penetrate through the cabinet. Make sure that you have
the proper chains/straps/joists and equipment to keep unit secure. Intake
(Marked as 'Air In' on unit):
• Intake ducts should be installed upstream of any humidifiers and be
installed on the main return.
• Intake duct should be installed at least 6 ft. away from the outflow duct on
the main return. Outflow (Marked as 'Clean Air Out' on unit):
• Outflow duct should be installed as close to the air handler/furnace inlet as
possible but not directly into the return air elbow of the main return.
• If the unit is being installed independently of any other system, room diffusers
are recommended to help distribute airflow evenly in the occupied space.
Ducting:
• If HEPA system is installed where inlet and outflow collars face down, metal
elbows must be connected to both inlet and outflow collars.
• Each connection must be sealed with aluminum tape or mastic, including
all take offs.
• Installed duct runs should be as straight as possible (if the duct runs are
too long, reduced CFM may result).
• If duct is exposed to unconditioned air, externally insulated flex duct is highly
recommended.
• Externally insulated flex duct can also be used for noise reduction purposes.
• For best indoor air quality, do not use ductboard or fiberglass inside of ducts.
Electricity:
• The unit must be plugged into a grounded 20V, 60Hz outlet.
