
Thank you for your purchase of a RecoupAerator 2000DX, the most advanced energy recovery
ventilation system available today! Your RecoupAerator 2000DX is designed to bring fresh,
filtered air into your building while simultaneously exhausting stale air.
The 2000DX is an Energy Recovery Ventilator (ERV), meaning the RecoupAerator recovers and
transfers air temperature and moisture from the stale outgoing air to the incoming fresh air.
No matter what the season, you stay comfortable while breathing fresh clean air.
In addition to having an energy transfer rating of up to 95%, the RecoupAerator moderates
indoor humidity in the winter and turns away outdoor humidity in the summer.

The RecoupAerator 2000DX is a modular unit with separate housings for the fans and heat
recovery wheel. The Fan Housing contains the intake and exhaust fans and their associated
controls while the Wheel Housing contains the heat recovery wheel and its respective drive
components. The two housings are coupled via external draw latches and join with an
airtight seal. The heat recovery wheel is made up of removable cartridge filter inserts
which contain the heat recovery and filter material. The cartridge inserts allow the heat
recovery and filter material to be easily removed and cleaned. Both housings sit on a
vibration isolating rubber pad on the included base which has vibration dampening,
adjustable height feet. The 2000DX controls are custom per installation.
The 2000DX has four 18” dia. duct connections. Please see illustrations contained in this
manual. Both housings have removable doors at each duct connection for access to the
interior for maintenance. All user performed maintenance will occur in the Wheel Housing.
The Fan Housing contains no user adjustable or replaceable parts.

Case: 16 gauge baked powder coat sheet steel insulated with 1.5
inch EPS with flame retarder additive.
Blowers: Two maintenance free EBM backward inclined motorized
ECDC impellers with permanently lubricated sealed ball
bearings and thermal overload protection.
Wheel motor: Maintenance free ECDC motor with permanently lubricated
sealed ball bearings and thermal overload protection.
Energy Recovery Core: The energy recovery core is manufactured from a blend of
visil and nylon designed to transfer both sensible and latent
heat. The core also acts as the MERV 8-12 filter.
Controls: Standard control is on/off function with capability of setting
continuous flow within the operating flow range of 200-2000
CFM. Boost input, external control input, pressure input are
available.
Serviceability: The unit is designed in two main housings (wheel housing and
fan housing). The unit can be split in two for transport,
service, and installation. Each of the two housings have two
doors for ease of service. The wheel is accessible for cleaning
without removal-or easily removed for more detailed
cleaning.
Mounting: Unit comes with a vibration mounting stand. Any other
orientation is acceptable with the proper designed mount and
access.
 The RecoupAerator is warranted to be free from defects in material and
workmanship, and all parts for a period of 2 years from purchase date.
The energy recovery core is warranted for 5 years with a proper yearly cleaning schedule.


Install the 2000DX in a position where ventilation ducts can be easily run to each of the
four duct connection points and there is adequate room to access each door on the unit for
maintenance purposes. (See Airflow Diagrams for duct connection locations and airflow
designations, these are also labeled on the unit.) It is recommended that there be at least
36” of clearance at each duct connection point to ensure there is enough room to remove
the doors. To facilitate easy duct removal for maintenance, make a portion of each duct
section, 24” to 36”, easily removable.

The 2000DX is supplied ready to be hard wired to a building power system. Terminal blocks
are supplies in the electronics cover of the Fan Housing to connect power to. To connect
the power wiring, remove the four sheet metal screws holding on the electronics cover.
Be careful when removing the cover on the Fan Housing, as the control knob is in some
configurations affixed to the cover. Wire the terminal blocks as shown in the illustrations.
Please see the Diagrams for additional reference.
Always wait at least 60 seconds before turning power back on.
Fan Housing Wiring Arrangement
The Fan Housing should be wired to a 240 VAC, single phase, 50 / 60 Hz dedicated circuit
with a maximum service rating of 15 Amps.

The DX2000 is set to provide a constant pressure inside the main duct despite the flow
changes. The main control board DCC7545 and a feedback pressure transducer: Veris
PXDLX01S are used to accomplish the function. Both the DCC7545 and the transducer are
powered by the 24VAC power.
The transducer is mounted on the duct monitoring the inside pressure. The output signal is
a DC signal varying from 0V~10V. The DCC7545 takes the signal as a feedback and uses the
PID control strategy to maintain a constant pressure inside the duct which can be set by
three jumpers on the DCC7545.

When the RecoupAerator is wired directly to the optional CO2 monitor, the air flow will be
controlled by the CO2 level input. The CO2 monitor will respond approximately as follows:
<800 ppm CO2: lo flow 240 CFM
800-1000 ppm CO2: med flow 720 CFM
1000-1200 ppm CO2: med hi flow 1210 CFM
>1200 ppm CO2: hi flow 1795 CFM
The control will default to the higher flow position –being the command from the CO2
monitor or via the dial control.

The RecoupAerator is EconoCool-equipped, so that you can make use of outside air in
summer (e.g., during the night) to cool your building, thereby providing AC energy savings.
Using a temperature sensor on the incoming air stream and a sensor on the room
temperature, the RecoupAerator automatically stops energy recovery at some preset
certain conditions. The user can select between the presets by changing JP2~JP6.
