Select a location so that:

The fresh air inlet from the outside is placed a minimum of 10 feet from any other exhaust vent

The two ducts to the outside are as short and straight as possible for the best system performance

The door can be opened to clean the core and filters conveniently. Provide clearance at front of unit for service access to the  

blowers, filters and energy exchange core (minimum 20-1/8" for full door swing, 14-1/4" for door removal from hinges)

The exhaust outlet to the outside and fresh air inlet from the outside of the building should be at least ten feet apart to 

avoid cross-contamination. The exhaust duct should be about the same length as the fresh air duct

The exhaust outlet should NOT dump air into an enclosed space or into any other structure

Th

e preferred mounting location for the unit is on a concrete foundation wall because the foundation wall isolates any blower 

vibration. If a basement area is not available or practical, use other mechanical room space such as a closet, garage, storage, or 
accessible attic or crawl space.

** If you locate the unit in an attic or other unconditioned space, all of the unit's ductwork that is located in the attic MUST be

** 

insulated.

 Use at least R-6 insulation
