BR70 AND BR130 INFO PURPOSE OF AN ENERGY RECOVERY
VENTILATION (ERV) SYSTEM
Many modern homes are built air-tight for energy
efficiency and comfort. The result is that natural
air infiltration rates are often too low to provide
acceptable indoor air quality. The solution is to
use an ERV to remove gaseous pollutants such as
odors, winter-time excess humidity, formaldehyde,
smoke, radon, vapors from cleaning products, and
other chemicals. The removal of dust and other
small particles from your home is not the function
of an ERV.
WHEN SHOULD YOU USE YOUR ERV?
Use your ERV when windows are closed and you
need to ventilate. When the outdoor air is warmer
or cooler than comfortable, the ERV will allow
a quieter, more secure home with the windows
closed and will also save energy.
USING AN ERV WITH AIR-CONDITIONING
An ERV works very well with air-conditioning,
because its “enthalpy-transfer” energy-exchange
core will reduce the amount of moisture in
the outside air that is brought in. ERVs are the
preferred way to ventilate while air-conditioning
because it brings in less moisture than any other
ventilation method.
CONTROLLING EXCESS HUMIDITY
DURING COLD WEATHER
When the ERV is first turned on at the beginning
of the heating season (or when first installed), it
will have to run full-time for several days to reduce
indoor humidity levels. The proportional timer
should be set to “100%” for several days whenever
you have a problem with excess humidity during
cold weather.

TABLE OF CONTENTS
There is no known safe level of
cigarette smoke. Any ventilation
system may provide noticeable
improvement in spaces where
cigarettes are smoked, but it
cannot be expected to protect
against the severe long-term
health hazards of exposure to
cigarette smoke.
WARNING
ABOUT RENEWAIRE
For over 30 years, RenewAire has been a pioneer in improving people’s health, cognitive function,
productivity and wellbeing by enhancing indoor air quality (IAQ) in homes and buildings of every type.
This is done energy-efficiently, cost-effectively and sustainably via our fifth-generation, static-plate,
enthalpy-core Energy Recovery Ventilators (ERVs) and Dedicated Outdoor Air Systems (DOAS) that
reuse otherwise-wasted energy to condition incoming outdoor air. This process optimizes energy
efficiency, lowers capital costs by reducing HVAC loads and decreases operational expenses by
downsizing equipment, resulting in major energy and cost savings. RenewAire technologies also
enjoy the industry’s best warranty with the fewest claims due to tremendous reliability, flexibility and
ease of use.
RenewAire was the first innovator with static-plate, enthalpy-core technology in the U.S., and is
currently one of the largest ERV companies in the country. Committed to sustainability and protecting
the environment, our manufacturing facility in Madison, WI is 100% powered by renewable energy
and is on track to be one of the few buildings worldwide with LEED Gold, Green Globes and ENERGY
STAR certifications. Our technology excels in every geography, every climate, every building and
every application, enabling RenewAire to be everywhere. In 2010, RenewAire joined the Soler &
Palau Ventilation Group, providing direct access to state-of-the-art, air-moving technology. For more

BEFORE YOU BEGIN
There are two general ways that the BR models can be installed. This manual covers duct hung
installations. Please refer to the Thru-Wall instructions packed with the TW kit when installing units to
an outside wall. Read all instructions before installing the unit. Also review supplemental instructions for
the Thru-Wall kit if used. Carefully unpack and inspect the unit for shipping damage. Attach the two duct
collars with the screws provided in the plastic small parts bag.
PLANNING
YOUR INSTALLATION
INSTALLATION
LOCATION OF THE UNIT
Select a location so that:
• The unit is hung on the furnace or air conditioner
return trunk line.
• The two ducts to the outside are kept as short
as possible with few gentle bends. Keeping all
ducts as short and simple as possible provides
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. Unbalanced flow
can cause poor performance from the unit and
may even result in frosting of the core during
extremely cold weather.
• The fresh air intake vent from the outside is
placed a minimum of ten feet from any other
exhaust vent.
• The power cord reaches an electrical outlet.
• The front cover 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 exchanger core.
It is recommended that the BR units be used
with standard furnace air handling equipment
with velocities not exceeding 750 fpm at the
point in the return air duct where the BR unit is
attached. An alternate field measurement would
be to locate the BR unit where the static pressure
measurement does not exceed -0.2 inch. If the air
handling system is high velocity or high pressure
then the EV Series of products by RenewAire is
recommended.
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.
Provide Adequate Service Access
for Maintenance. The unit will
require regular filter and core
inspections. Install the unit where
you can access the core for
cleaning and replacing the filters,
and where you can get at the
wiring for installation and service.

Risk of injury when lifting unit
and installing it overhead. Get a
helper and wear eye protection.
CAUTION
NOTE: All the provided brackets
should be installed surrounding
the opening between the unit
and return duct.
MOUNTING THE UNIT
Mounting the unit on ducting
The unit can be mounted on a return duct in
various orientations. It can be attached to the
bottom of the return duct in lengthwise or
crosswise orientation. It can be attached to the
side of the return duct. The different orientations
are shown in Figures F2-F5.
Mount the unit hanging bracket to the unit. Attach
the hanging bracket to the duct work. Make sure
the unit orientation provides for proper airflow
direction in the return duct. Refer to the air flow
direction label on the unit. Using the template
provided cut a rectangular hole in the duct work.
To add rigidity to the duct, bend the edges of the
hole into the duct as flanges. Check the gasket on
the back of the unit to ensure it is free of tears
F6
Mounting the Thru-Wall Kit
As another installation option the Breeze unit may
be mounted directly to the inside of an exterior
wall. The Thru-Wall kit must be used for this
application. Refer to Thru-Wall instructions packed
with the TW kit.
The Thru-Wall Kit, or TW, consists of two hoods,
insulated metal ducts, an interior mounting plate,
and small air seal gasket. See Figure F6. The
interior plate is attached to the interior of the wall.
Using the holes in the plate as a reference cut 6"
holes to the outside allowing for a downward tilt
to the outside of ½" for 12" of duct length. The
insulated ducts are slid through the holes from the
inside of the building. Bend over the tabs at the
ends of the ducts on the outside of the building.
These tabs can be attached to the building to keep
the duct in position.
Duct length must be adjusted by cutting the duct
to size. Allow a maximum of ½" of duct to extend
past the interior wall covering.
Attach the wall caps to the exterior of the building.
The wall cap with a rain guard is for the fresh air
duct and the small wall cap without rain guard is
for the exhaust air duct. Install appropriate flashing
and sealing around the wall cap flanges to prevent
moisture penetration into the building structure.
See instructions packed with the TW kit for more
information.
Thru-Wall kit
and rips. Add the long piece of gasket provided
in the hardware kit to the back of the unit to
form a rectangle with the other three pieces of
gasket already applied. Lift the unit and connect
the hanging bracket on the unit into the hanging
bracket on the duct work. Use caution and an
assistant when installing the unit overhead.
Swing the unit into position and verify its fit. Attach
the unit end flanges to the duct work. Now fasten
the crosswise bracket to the duct work and then to
the unit. The smaller crosswise bracket may need
to be installed after the lengthwise bracket if one
of the unit flanges cannot be attached to the return
duct. Make sure the screws used are properly
selected for the loads and substrate involve.

RENEWAIRE.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.627.449910
INSTALLATION
INSTALLING OUTSIDE AIR AND EXHAUST AIR DUCTS
For duct hung applications, the exhaust outlet and fresh air inlet on the outside of the building should be
at least ten feet apart to avoid cross-contamination. Keep the length of the two flexible ducts roughly
equal and as short and straight as possible. Normally, six inch insulated flexible duct is used. Band or tape
inner duct liner to inner flange of appropriate collar. Drive a sheet metal screw through liner to secure duct
spiral wire to collar. Straighten insulation, and slide outer duct jacket onto the outer flange of the duct
collar. Secure with band or tape.
If duct runs are exceedingly long (over 10 feet of flex duct for 130 CFM) or have excessive bends or
elbows or if maximum air flow rates are required, eight inch insulated flexible duct should be used. The
outer flange of the duct collar can be used for both the inner and outer jacket of the flexible duct. Care
must be taken to ensure that the duct is securely fastened and sealed to the duct collar. Ducts connecting
the unit to the outside must be insulated with sealed vapor barrier on both inside and outside of the
insulation.
The inlets and outlets should be screened against insects and vermin and shielded from the weather to
prevent the entry of rain or snow. The exhaust outlet should not dump air into an enclosed space or into
any other structure.
INSTALLATION INSTRUCTIONS
INSIDE DUCTWORK SYSTEM (FOR WALL MOUNTED UNITS ONLY)
Collect Stale Air from the House
Locate stale air return grilles (RA) in rooms where moisture and odors are generated: stale air returns
(which pick up stale household air to be exhausted) should be located in bathrooms and the kitchen. A
central location such as a hallway is also acceptable but won't clear humidity and odors from baths and
kitchens as rapidly.
Connect Fresh Air from the Unit to the House
Use a five foot section of flexible insulated duct to connect the unit to the return air duct at the port
labeled Fresh Air (FA). Note that the flex duct is not required for the room air connection (RA). This will cut
noise transmitted from the unit. Stretch the flex duct tightly in order to maintain good airflow.
For houses with forced-air heating and cooling systems
Most units are installed with the fresh air duct connected directly to a return duct for the main heating
and cooling system. Be careful to connect the fresh air duct at least three feet from the return plenum to
minimize suction from the furnace blower. A connection closer to the furnace may result in unbalanced
flow and associated problems.
For houses without ducted heating or cooling systems
In most houses one or two fresh air grilles in a central part of the house provide effective distribution of
the fresh air into the home, particularly when the stale exhaust air is picked up at several points. Because
the fresh air is usually somewhat cooler than the household air, the fresh air supply grilles should be
located in a traffic area like a hallway or stairway rather than in a sitting area.
CAUTION
INSTALL FRESH AIR INLET
AWAY FROM SOURCES OF
CONTAMINANTS.
• Do not locate the fresh air
inlet where vehicles may be
serviced or left idling.
• The fresh air inlet should be at
least ten feet away from any
exhaust such as dryer vents,
chimneys, furnace, and water
heater exhausts or other
sources of contamination or
carbon monoxide.
• Never locate the fresh air inlet
inside a structure.

START-UP & OPERATION
START-UP STARTING UP THE UNIT
• Inspect your installation to be sure all duct work
is correctly installed and sealed, that filters are
in place, and controls (if any) are connected.
• Shut and latch the door to the unit.
• Plug unit into 115 VAC outlet. It may start
immediately.
• Use control to turn on the unit. Check operation
of the control(s).
• Check that the unit’s safety interlock switch
turns off the unit when the door is opened.
VERIFYING UNIT PERFORMANCE
AIRFLOW
Airflow should be occurring in both airstreams. Sometimes the easiest place to confirm that air is moving
is at the external wall caps.
If exact airflow is critical, it may be desirable to permanently install flow measuring stations and
manometers. These can also be used to determine when filters should be cleaned or changed.
Use Static Taps to Measure Aiflow Rates
See "Cross Core Static Drop" in MEASURING AIRFLOW table on page 13.
Use Damper to Balance Air Flow to Desired Rates, if necessary
The ERV's blower motor are well suited for volume control by dampers on the inlet of the unit. One
balancing damper is provided in the unit parts tray. NOTE: The unit is considered balanced if the
difference between the two airflows is not more than 10 CFM.
After measuring the airflow of the unit, the balancing damper may be used to balance airflow if desired.
Place the damper between the duct collar and the unit for the RA (Through Wall) / OA (Duct Hung)
airstream. NOTE: Install the damper as shown in Figure 8 below.
Slowly move the damper further into the duct until the desired airflow is recorded. Secure the damper
in place using 1/8" tek screws (provided). NOTE: Drilling through the case while the unit is running may
cause metal shards to be drawn into the unit.

EQUIPMENT REQUIRED
•A magnehelic gauge or other device capable of
measuring 0 to 1.0 in. water of differential pressure.
•2 pieces of natural rubber latex tubing, 1/8” ID,
1/16” Wall works the best.
NOTE: Be sure to remove cap from pressure port
before inserting tubing. Insure tubing is well seated
in pressure ports.
NOTE: The tubing should extend in the pressure
port approx. 1 inch.

Fresh Air (FA) CFM 16 31 47 62 78
Room Air (RA) CFM 16 31 47 62 78
The individual differential static pressures (DP)
are measured using the installed pressure ports
located in the front of the units core access doors.
NOTE: These ports are carefully located on the unit
to give the most accurate airflow measurement.
Do not relocate pressure ports.
• To read SCFM of Fresh Air (FA) install the “high”
pressure side (+) of your measuring device to the
Outside Air (OA) port and the “low” pressure side
(-) to the Fresh Air (FA) port.
• To read SCFM of Room Air (RA) install the “high”
pressure side (+) of your measuring device to the
Room Air (RA) port and the “low” pressure side
(-) to the Exhaust Air (EA) port.
• If gauge drops below zero, reverse tubing
connections.
• Use the reading displayed on your measurement
device to cross reference the CFM output using
the conversion chart.
NOTE: Be sure to replace cap into pressure port
when airflow measuring is completed.
NOTE: For best performance the airflow rate for
both the Fresh Air and the Exhaust Air should be
roughly equal (“balanced”). In some facilities a
slight positive or negative pressure in the building
is desired. RenewAire energy recovery ventilators
can generally operate with a flow imbalance of up
to 20% without significant loss in energy recovery
efficiency.

MAINTENANCE
REQUIREMENTS
Keep your ERV performing at its best by cleaning it as described below:
TO CLEAN THE ENERGY EXCHANGE ELEMENT
Vacuum the Face of the Energy Exchange Element Yearly.
Dust collects only on the entering faces of the energy exchange element. The interior of the energy
exchange element stays clean even if the element faces are dust covered. The RenewAire core airflow
paths are designed to transport the air in a laminar motion. The core flutes move the air in a laminar
airflow such that particulate deposition is maintained at virtually nill.
1. Remove the filters (see below).
2. Vacuum the exposed faces of the energy exchange element with a soft brush attachment.
3. After servicing the filters, re-install them (see below).
4. Vacuum out dust from the rest of the unit case.
INSPECT AND CHANGE THE FILTERS REGULARLY
Service filters every three months when the unit is in regular use or as needed to keep them reasonably clean.
1. Release cam latches and carefully swing access cover open. The cover may be removed by sliding to
one side.
2. In BR130 units, remove filter clips.
3. Pull the filters out.
4. Vacuum with a hose attachment.
5. Re-install filters and filter clips. Orange side of filter should face the core.
6. Re-install cover and fasten cam latches.
NOTE: Filters should be replaced after they have been cleaned several times. The primary contact for
replacement filters for your RenewAire unit is the installing contractor. As an alternative, you may wish to
produce your own filters following these instructions:
Filters may be cut from a sheet or roll of ¾" - 1" firm, spun polyester filter “hog hair” media or material,
similar to the existing filter in the residential unit.
The size of each filter (2 required per unit) is as follows:
BR70 7" x 10 ½"
BR130 10 ½" x 10 ½"
Call your HVAC contractor or RenewAire for further information.
NOTE: Filters must be used or the face of the energy exchange core will become blocked by dust and
reduce unit efficacy. The filters supplied in the unit are usually able to keep the energy exchange core
clean for many months. Finer filters can be used but must be cleaned more often.
MOTOR MAINTENANCE
The blower/motor package needs no lubrication.
If necessary, vacuum clean the blower wheels at the same time you clean the face of the energy
exchange element (yearly). Confirm blower wheel is not rubbing against the blower inlet or housing by
rotating wheel manually.
GENERAL CLEANING AND INSPECTION
Perform general cleaning and visual inspection when changing filters.
1. Remove paper, leaves, etc. from inlet and outlet screens.
2. Inspect for insect nests.
RISK OF ELECTRIC SHOCK
OR INJURY.
• Before servicing or cleaning the
unit, unplug the unit line cord.
• Make sure unit is not running
before opening its door. Blower
wheels are sharp and can cut.
• Do not disable the interlock
switch: it is there for your
safety.
WARNING
DO NOT WASH THE ENERGY
EXCHANGE CORE.
Keep it away from water or fire to
avoid damaging it. Always handle
the core carefully.
