Healthy Climate® 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.

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 HEPA system 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.
Inlet (Marked as ‘Air In’ on unit):
•Inlet ducts should be installed upstream of any humidifiers and be installed on the main return.
•Inlet duct should be installed at least 8 ft. away from the outlet duct on the main return.
•Use a 45 degree takeoff to draw air from the main return.
Outlet (Marked as ‘Clean Air Out’ on unit):
•Outlet 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.
•To reduce static pressure, install outlet with a 45 degree takeoff directly
•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 outlet
collars face down, metal elbows must be connected to both inlet and outlet 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 120V, 60Hz outlet.
