Thank you for your recent purchase of the most
advanced air filtration and energy recovery
ventilation available today. Your RecoupAerator
is designed to bring fresh filtered air indoors to
your home or business while simultaneously
exhausting stale air.
The 200DX is an Energy Recovery Ventilator (ERV),
meaning the RecoupAerator captures
temperature and 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 96%, the RecoupAerator
moderates indoor humidity in the winter and turns away outdoor humidity in
the summer.
Automatically self-balances air flow
96%+ heat recovery efficiency
95% filtration at 1.8 microns (MERV 12)
Up to 75% moisture transfer capability (depending on season)
UL listed and certified
ECM motors with Permanently lubricated Ball Bearing
Optional Pressure Transmitter (senses and adjusts for changes in indoor air
pressure)
Optional CO2Guard™ (senses and adjusts for elevations in CO2)
EconoCool™ (brings in cool, filtered night air in summer)
Compatible with many IAQ monitors and fans
Automatic frost prevention down to 10° F
Variable blower speed
Quiet operation
Low/easy maintenance
Exceeds ASHRAE 62.2 ventilation recommendations
No drain required
Filter service indicator
Fully insulated
5-year Warranty

Application
The 200DX is an Energy Recovery Ventilator (ERV),
meaning that the RecoupAerator captures temperature
and moisture from the stale, outgoing air and transfers
it to the incoming air stream.
Controls
RecoupAerator is equipped with a variable speed
controller, unlimited boost function capability (i.e., you
can add timers and controllers), “check filter” indicator
light, EconoCool™ equipped, auxiliary IAQ and timer
inputs, furnace wiring terminals, and auxiliary output.
These controls allow you to adjust the airflow as
needed to maintain a comfortable level of fresh air. The
“check filter” indicator light is designed to let you know
when to check and/or clean/replace your pre-filters
and energy transfer/filtration material. For systems in
which constant ventilation is not required, a remote
on/off switch, timer, and/or furnace inputs can be
wired directly to the unit.
Frost Control
Programmed to regulate heat exchange automatically
to prevent frost build-up down to approximately 10˚F.
During this mode, the Wall Dials green light will flash.

We strongly recommend a licensed HVAC technician install this product,
because of complex considerations such as airflow dynamics and condensation
issues. 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 make sure that the following are
included and undamaged:
UltimateAir RecoupAerator 200DX Energy Recovery Ventilator with four (4)
starter collars packaged inside the RecoupAerator.
Literature package with maintenance guide, parts list, registration card, and
warranty.
Wall mountable control dial (pre-wired for test run, and shipped inside the
RecoupAerator).
Control options if ordered.

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 be sure to complete the
Warranty Registration to validate the installation.

CAUTION
Always disconnect the power supply before wiring to prevent
electrical shock and/or equipment damage.
The RecoupAerator is equipped with a grounding plug for your
protection against shock hazards and should be plugged directly into
a properly grounded, 230V, 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 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 building, contact a qualified electrician.

Option 1: Dedicated Ventilation Ducting
This is the most complete installation option and is ideal for new construction.
Use option 1 when a home or business is especially concerned with health
issues (e.g., when an occupant has asthma or severe allergies). Option 1 is the
only option for homes and businesses without existing forced air ductwork.
Option 1 is also used for homes employing radiant heat flooring or geothermal
heating.
The more rooms to which ductwork is run, the more effective the system will
be. Dedicated ductwork is installed for the exhaust intake and the fresh air
delivery. The kitchen, laundry room, and other areas with high contamination
should contain registers for the exhaust intakes. Areas such as the living room,
den, and bedrooms should receive the full benefit of the fresh air being
brought in, and a good installation will feature supply vents in these locations.
As a general note, fresh air is generally supplied at floor level, and stale air is
removed at ceiling level.
A simpler but somewhat less effective version of this system uses one exhaust
and one or more delivery registers located strategically to encourage
circulation throughout the house.

Option 2: Shared Forced Air Supply, Dedicated Stale-Return
This method partially uses the existing HVAC duct system. Fresh Air IN from
the RecoupAerator® gets ducted into the cold air return side, or the supply
side of the furnace. Stale Air Out thru the RecoupAerator® is ducted separately
to strategically located points throughout the house from which you’d like to
remove stale air (e.g., the kitchen, bathroom, open stairwell). This method
allows for independent control between the HVAC air handler and the
RecoupAerator® (i.e., the air handler and the RecoupAerator® are not
interlocked and run independent of each other).

The UltimateAir® RecoupAerator® 200DX Manual and Installation Guide, March 2014 
Option 3: Shared Forced Air Supply, Shared Return
This method uses the existing HVAC duct system completely.
Fresh Air IN from the RecoupAerator® is ducted to the main
supply duct to the house. The Stale Air Out thru the RecoupAerator®
is ducted into the cold air return duct of the furnace. If you use this
method, we recommend that you wire your RecoupAerator® and
your air handler to run simultaneously (i.e., they will be interlocked) to
prevent recirculation shorting thru back past the furnace air handler.
Option 4: Shared Forced Air Return
This method uses the existing HVAC duct system
completely. Both the Stale Air Out and the Fresh Air
IN from your RecoupAerator® are attached to the
cold air return duct of your HVAC system. Be sure to
keep at least three feet of space along the cold air
return duct between the two RecoupAerator ducts.
When using this method, your RecoupAerator® and
your air handler must be wired to run simultaneously
(i.e., they are interlocked).
