Introduction
Welcome to the most advanced whole-house air filtration & Energy
Recovery Ventilation on the market today.
Energy Recovery Ventilation (ERV) means this machine captures
temperature and a portion of the moisture from the stale, outgoing air and
transfers it to the incoming Fresh Air. No matter what the season, you will
be comfortable breathing fresh clean air.
In addition to having an energy transfer rating of 99% ASE, the UltimateAir
ER80M moderates indoor humidity in the winter and turns away outdoor
humidity in the summer.

Installation & Ducting
We recommend a licensed HVAC technician install this product, because of
complex considerations such as airflow dynamics and condensation issues.
Please read these instructions carefully before beginning any installation
procedure. Failure to follow them closely may reduce ventilation
effectiveness, cause a hazardous condition, and/or invalidate your
warranty. Installation by non-licensed HVAC personnel may void the
warranty.
Unpack your RecoupAerator and check to be sure the following items are
included and undamaged:
•UltimateAir RecoupAerator ER80M Energy Recovery Ventilator
•Wall mount control dial pre-wired for test run.
•Power cable.
•Aux cable for accessory options.
•Literature package with this manual, & warranty registration.

Model ER80M :: ultimateair.com :: Athens, Ohio 45701 :: 740.594.2277
When Installing:
1. Test Run the RecoupAerator by plugging into a power outlet, and
adjust the blower speed with the included Wall Dial. Familiarize
yourself with the intake and outlet duct configuration and installation
dimensions. Decide how you will mount the unit. We recommend
ACCA’s manuals D & J for proper load calculations and duct sizing.
2. After installation is complete, fill in contractor’s name and phone
number on the last page of this manual, and please complete the
Warranty Registration to validate the installation.
CAUTION
Always disconnect the power source
before wiring to prevent electrical shock
and/or equipment damage.
Electrical requirement: 120 VAC, single phase, 3 AMP max
no preheat or 6AMP max with preheat
The RecoupAerator is equipped with a three-pronged grounding plug for
your protection against shock hazards and should be plugged directly into a
properly grounded, 120V, three-pronged wall receptacle. If only a two-
pronged outlet is available, it must be replaced with a properly grounded
three-pronged receptacle in accordance with the National Electrical Code
and local codes and ordinances. A qualified electrician should do this work.
Use proper circuit protection. If you have any doubts about the grounding in
your house, contact a qualified electrician.

Model ER80M :: ultimateair.com :: Athens, Ohio 45701 :: 740.594.2277
Positioning the RecoupAerator
We recommend the RecoupAerator be mounted in a conditioned space, as
this will affect the performance and longevity of the unit. If the
RecoupAerator is installed in an unconditioned space, the section(s) of
inside ducts, and possibly the unit itself may need to be insulated from the
unconditioned environment.
Position the RecoupAerator in a location convenient to existing
ducting. If possible, locate equipment away from the quiet rooms (e.g.,
bedrooms). Avoid directly suspending the RecoupAerator from the mid-
span area of joists. This can result in structural vibration. Allow adequate
space for maintenance and service of the RecoupAerator.

Ducting to Outside
Note: The ducts to the outside must be insulated.
The collars labeled “to Outside” must be ducted
through the exterior of the building, and the
following precautions should be taken.
1. The ends of the two ducts should be as far
apart as practical (at least six feet, either
horizontally or vertically) to minimize
re-circulation of the exhaust air.
2. Terminate the ducts using exterior weather
hoods. Ensure that the exterior weather caps
have wire mesh to keep out birds and debris.
Angle the weather caps down and away from
each other and place them away from exhaust
vents for other appliances such as dryers or
hot water heaters. Avoid placing air intake
vents near exhaust vents from adjacent
buildings or sources of automobile exhaust.
Never place an air intake in a garage, for
instance.
3. Make sure that the joints between the
termination vents and the walls are weather
sealed.

Connecting Duct Work
Ducting between the RecoupAerator and the outdoors must be insulated
and sealed with a vapor barrier to prevent condensation.
1. Locate the three tabs at each duct hole and bend them ‘out’.
2. Apply a bead of silicone or general sealant inside the duct opening
where the crimped end of a male 4” duct starter will intersect and
insert the fitting into the opening until it stops against the inside
wall (approximately 1”). The sealant is to create an air seal
between the ERV duct opening and the inserted duct. Any male
crimped 4” transition fitting can be used. UltimateAir
recommends a minimum of a 5” to 4” taper reducer at all four
collars. Some installations will require 6” to 4” starting out.
Minimum trunk duct diameter is 5”.
