Before you begin
Read all instructions before installing the unit. Also review
supplemental instructions included with any controls that will
be installed. Carefully unpack and inspect the unit for
shipping damage. Open the access door and inspect inside the
unit. Attach the four duct collars to the unit with the screws
provided in the plastic small-parts bag.
Location of the Unit
Select a location so that:
♦
The fresh air intake vent from the outside is placed a
minimum of ten feet from any other exhaust vent, and is
at least 30” long.
♦
The two ducts to the outside are as short and straight as
possible, for the best performance from the system.
Shorter duct runs help assure that the system is balanced:
the amount of air brought in is equal to the amount of air
exhausted.
♦
The power cord reaches an electrical outlet.
♦
The door can be opened to allow cleaning the core and
filters.
Provide at least 24” of clearance at front of unit
for service access to the blowers, filters and energy
exchange core.
♦
The exhaust outlet and fresh air inlet on 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.
♦
Do not install the exhaust outlet and fresh air inlet through
the roof or roof soffit. If these are the only available
options call RenewAire technical support for help.
The preferred mounting location for the unit is on a concrete
foundation wall because the foundation wall will isolate 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 wish to install the unit in an attic or other
unconditioned space, you must insulate all of the unit’s
ductwork that is located in the attic. Use at least R-6
insulation.
