LOCATION OF THE UNIT
Select a location so that:
• The fresh air inlet from the outside is placed a minimum of ten 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 (22 3/4" min. for full door swing)
• 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
The preferred mounting location for the unit is on a concrete structure because a concrete structure 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.
NOTE: 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.
