Dealer Installation Instructions
The HEPA systems can be used independently of any other equipment! The 
intake and outflow of the filtration system can be ducted into the same room 
to create a cleaner enviro ment almost anywhere. The intake or outflow can also 
be ducted elsewhere. The intake and outflow should be installed on opposite 
sides of the room; however, this varies according to your specific needs.
Preparation:
Here are some things to consider as you decide where to install the HEPA 
system independently of other systems.
Location:
• Make sure there is room to open the HEPA filter access panel for filter 
changes/inspections.
• 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. 
Intake (Marked as ‘Air In’ on unit):
• Intake ducts should be installed near the floor for optimum airflow. 
  If space does not allow, then the inlet can be installed in the ceiling.
• Intake duct should be installed at least 6 ft. away from the outflow duct.
• Intake duct should be installed at opposite end of the room from the  
outflow duct(s) if in the same room.
• Diffusers are recommended to help distribute airflow evenly. 
Outflow (Marked as ‘Clean Air Out’ on unit):
• Outflow(s) should be installed in the ceiling away from any other air inlet(s)
• 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 vent connections.
• 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, insulated flex duct is highly  
recommended.
Example of Single Room Stand Alone System Installation
For single rooms where increased filtration is desired such as a dedicated 
‘smoking room’.
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.

NOTE: Be sure to review ‘Rules for Safe Installation and Operation’ on page 
 of this document before start-up of this unit.
Operation (350 & 675)
 Make sure that the unit is plugged into a grounded power source  
(20 Volt, 60 Hz).
2 For optimum performance, the HEPA system should operate with the 
indoor air handler/furnace blower on.
3 Turn the unit on by pressing the on/off button and the green power light  
will illuminate.
4 To turn the unit off, press the on/off button and the power indicator light will go out.
Filter Light Indicators
Your HEPA system is equipped with an electronic filter timer. This timer  
monitors the life expectancy of each filter in the unit. By default, the Pre-Filter, 
HEPA Filter and VOC Blanket lights will turn on when the unit is powered on.
5 Turn the unit off and see instructions for “filter removal” to determine if filter 
replacement is needed. See ‘Maintenance” on next page.
6 Once the filters have been checked or replaced, turn the unit back on and 
reset the control panel. To reset, press and hold the flashing filter button 
until the light is constant.
Air should be drawn from
location B if space is avail-
able, otherwise, use loca-
tion A.
