WARNING
!
Carbon Monoxide Poisoning Hazard
Failure to provide sufcient air needed for proper
combustion and exhausting of gases through the ue
(chimney) of fuel burning equipment that might be
installed in the area affected by this equipment may
cause Personal Injury or Death.
The unit is intended for general building ventilation.
Connection of the unit to ventilation exhaust, drier ex-
haust or ranger exhausts will damage the unit and could
result in hazardous levels of toxic materials in the home.
If this unit is exhausting air from a space in which
chimney –vented fuel burning equipment is located, take
steps to assure that the combustion air supply is not
affected. Follow the heating equipment manufacturer’s
guidelines and safety standards such as those published
by the National Fire Protection Association (NFPA),
the American Society For Heating, Refrigeration and
Air Conditioning Engineers (ASHRAE) and local code
authorities.
CAUTION
!
This unit is intended for general ventilating use only.
Do not use to exhaust hazardous or explosive materi-
als and vapors.
CAUTION
!
This installation manual shows the suggested installa-
tion method. Any structural alterations necessary for
installation must comply with all applicable building,
health and safety code requirements.
ERV LOCATION CONSIDERATIONS
· Select a location to install the ERV with the objective
of keeping the fresh air supply ducts and exhaust
ducts as short as possible. Short runs provide the
best performance and help ensure system balance;
the amount of air brought into the home equals the
amount of air exhausted. Unbalanced air flow can
cause poor performance and may result in frosting of
the core during extremely cold weather. See ACCA
Manual D for ducting guidelines.
· If the fresh air supply from the ERV is connected to the
heating and cooling system return air duct, locate
the ERV as close to the furnace or air handler as
possible.
· If the ERV is to be installed independent from the
forced air heating and cooling system locate the ERV
to minimize the length of all duct runs.
· An electrical outlet must be located within reach of the
ERV power cord. The power cord is 36 inches long.
· Provide at least 24” of clearance at the front of the ERV
for service access to the blowers, filters and heat
exchanger core.
· Provide access for maintenance so the front cover can
be opened to allow cleaning the core and replacing
the filters.
· ERV’s may be installed in a basement, mechanical
room, storage area, garage, accessible attic or crawl
area. Conditioned spaces are prefferred.
B. UNIT INSTALLATION
INSTALLATION ON A CONCRETE FOUNDATION WALL
Install hanging bracket to the wall with appropriate
concrete anchors (supplied by installer). Remove back-
ing from two 2” strips of foam tape and apply each piece
of foam tape equally spaced along the unit’s mounting
flange that will be held by the hanging bracket. (See
Figure 2)
The tape should be applied in a “U” shape to cushion
both the front and back of the integral flanges. Apply
the other two pieces of foam over the two holes that will
be used for fastening the other unit flange.
Lift unit and slide unit flange into the hanging bracket.
Use caution and an assistant when installing unit
overhead. Using metal flat washers, fasten flange op-
posite the hanging bracket to structure.
Safety concrete anchors should similarly be installed

INSTALLATION GUIDELINES
GENERAL GUIDELINES
1) Do operate the ERV independent of the indoor cen-
tral heating and cooling blower system (furnace / air
handler). Independent operation of the ERV allows
the ERV to introduce the minimum required fresh
air at all times of the year.
2) Do Not set up a control system that requires the
indoor (furnace / air handler) blower for the heating
and cooling system to operate (when in the cooling
mode) when the ERV operates. Fan operation during
the cooling mode without cooling occurring is not
recommended under most circumstances and ap-
plications. Fan operation evaporates the condensed
moisture (water) on the cooling coil and results in
increased Relative Humidity inside the home. For
exceptions and additional details, see the ERV Ap-
plication Bulletin.
3) Humidifiers and ERV/HRV’s. When the “fresh air”
is ducted into the return duct and the system is to
have a humidifier, install a “fan power humidifier.”
Do not install a by-pass humidifier, as it can freeze
based on the installation, outdoor temperature and
homeowner thermostat setback requirements.

C. DUCTWORK INSTALLATION - ERV TO
EXTERIOR WALL OUTLETS
CAUTION
!
Failure to follow this installation instruction may result
in property damage from sweating ductwork.
The fresh air duct and exhaust air duct connect the ERV
to the exterior wall outlet. Flexible or metal duct may be
used. The fresh air and exhaust air duct must be insu-
lated.
Keep the fresh air supply and exhaust duct roughly
equal in length and as short and straight as possible.
Typically, six (6) inch insulated flexible duct is used
for the EERVR100/200A1P00B and eight inch for the
EERVR300A1P00B. If using flexible duct band or tape
the inner duct liner to the inner flange of appropriate
collar. Drive a sheet metal screw through the liner to
secure the duct spiral wire to the collar. Straighten
insulation, and slide the outer duct jacket onto the outer
flange of the duct collar. Secure with band or tape. The
outer flange of the duct collar can be used for both the
inner and outer jacket of eight (8) inch flexible duct.
Care must be taken to insure that the duct is securely
fastened and sealed to the duct collar.
If duct runs are exceedingly long (over 25 feet of duct
for the EERVR100 or 300 and over 15 feet for the
EERVR200) see the Air Conditioning Contractors Asso-
ciation of America’s (ACCA) duct sizing manual “Manual
D” to design the appropriate sized ductwork.
FRESH AND EXHAUST AIR INLET AND
OUTLET INSTALLATION
WARNING
!
Failure to follow the installation instructions for loca-
tion of the fresh air inlet and return air grilles could
result in Carbon Monoxide Poisoning or Death.
The fresh air inlet should be at least ten feet away from
any exhaust such as chimneys, furnace vents, water
heater exhausts, dryer vents, driveways or other sources
of carbon monoxide or contamination. Do not locate a
fresh air inlet where vehicles may be serviced or left
idling. Never locate the fresh air inlet inside a structure.
Do not install return air grilles (stale air return) in ga-
rages, or in the same room with any gas fired appliance;
for example a gas fired furnace, gas fired water heater,

CAUTION
!
Failure to follow this installation instruction may result
in property damage from sweating ductwork.
Insulate all connecting ductwork from the ERV to any
indoor termination point that will be subject to forming
condensation. Flexible or metal duct may be used.
An ERV can be applied either with an independent free
standing fresh and return air duct system or the fresh
air supply can be connected to the cooling and heating
system return air duct. The following guidelines should
be considered when applying and installing either duct
system.
FRESH AIR DUCT CONNECTION TO THE COOLING
AND HEATING SYSTEM RETURN AIR DUCT
The Fresh Air Supply duct from the ERV should be
connected a minimum of three (3) feet up stream of the
indoor unit return plenum. (See Figure 7)
A connection closer than three 3 foot may result in
unbalanced airflow. Use a minimum of 5 foot section
insulated flexible duct to connect the ERV port labeled
“Fresh Air To Inside” to the return air duct.
FREE STANDING DUCT SYSTEM
For free standing ERV duct systems one or two fresh air
grilles located in a central part of the house will provide
effective distribution of the fresh air into the home par-
ticularly when the air to be exhausted from the home is
returned from several points. Use a minimum of 5 foot
insulated flexible duct from the ERV port labeled “Fresh
Air To Inside” to the point of termination.

Up to (6) PB controls, wired in parallel, may be used.
During winter, since fresh air is unconditioned, the fresh
air supply grilles should be located in a traffic area like
a hallway or stairway rather than in a sitting area.
Locate fresh air supply register within 12 inches of the
ceiling on an inside wall pointing the register louvers
toward the ceiling.. If fresh air is desired in specific
rooms with high occupancy the fresh supply air can be
split among the additional rooms.
RETURN AIR FROM HOUSE
Locate return air grilles in rooms where moisture and
odors are generated. Preferred locations for returns
are bath rooms, kitchens and hallways. Return grilles
should be installed within 12 inches from the ceiling on
an inside wall. Do not use returns to vent cooking areas.
Do not connect returns to a vent hood.
D. ELECTRICAL CONTROLS
WARNING
!
Hazardous Voltage – Disconnect Power Before Servic-
ing
Note: Proper Wiring Size Selection and Wiring Installa-
tion Is The Responsibility of the Electrical Contractor.
Controls
A percent timer (PT) control is included in the box with
the ERV. This is the primary control for operation of
the ERV. After startup, the PT control will operate the
ERV automatically. The PT control should be set by the
installing dealer.
To assist the dealer in determining the PT control set-
ting a ventilation calculator is available from your local
distributor. MicroSoft Excel is required to run this pro-
gram. The calculator input can accept a minimum venti-
lation airflow requirement per local code or calculate the
minimum airflow required per ASHRAE 62.2-2004.
In addition to the PT control some installations may
include Push Button (PB) or point of use control(s). The
PB controls are typically located in bathrooms or areas
where exhaust ventilation is required for short periods
of time. PB controls are wired in parallel to the PT con-
trols and energize the ERV whenever there is a manual
call for ventilation.
E. PERCENT TIMER CONTROL (PT)
The Percent Timer Control automatically energizes and
de-energizes the energy recovery ventilator every hour,
ensuring ventilation for the home around-the-clock. The
PT control has two status lights . One is the power light
located in the upper left hand corner of the control. The
other is the Runtime % light. The power light is on
whenever the PT control is calling for the ERV to run.
The Runtime % light is located on the right side of the
control. The Runtime % light indicates the amount of
time per hour the ERV will operate. Set the control per
your local code or ASHRAE Std 62.2 and your ventilator
will run once every hour.
FOR CONSTANT OPERATION: Press the fan icon
until the 100% light is on. The “Runtime %” light turns
on. The ERV unit will run continuously.
FOR MINIMUM VENTILATION REQUIREMENT
OPERATION: Set the control at the percentage that
meets local code or ASHRAE 62.2. Press the fan icon
until the light for the percent desired is on.
TO TURN THE ERV OFF: Press the fan icon until
all lights are off. The control is off. The ERV motor is
de-energized. (Power is still persent inside the unit.
Always unplug cord from outlet before servicing!)

4. Use Lutron Decora™ cover plate to complete the
installation (supplied by installer).
F. PUSH BUTTON POINT-OF-USE CONTROL
OPTIONAL ACCESSORY)
For use with all ERV models
OPERATION
The Push Button (PB) Point-of-use Control lets you
manually turn on your energy recovery ventilator for a
short period of operation – for example, when you are
using a bathroom. The PB Control must be connected to
a PT control to operate.
20-40-60 MINUTE VENTILATION CONTROL:
Press the fan icon and your ventilator will run for 20
minutes. Press again and the unit will run 40 min-
utes. A third press provides for 60 minutes of operation.
Percent Timer Control does not need to be on for the PB
Control to operate the ERV unit.
You can cancel a cycle at anytime. Just press the logo
and hold for about five seconds.
You can start another cycle by pressing the logo.
NOTE FOR ERV SYSTEMS WITH MORE
THAN ONE CONTROL:
Another control other than the push button may be
causing your ventilator to run. If you wish to keep your
ventilator from running, check that none of your controls
are calling for unit operation.
INSTALLATION
4. Install control in a standard 2" x 4" electrical box,
with a minimum depth of 1.5", with the two screws
provided.
5. Wire Size: 18 gauge, no more than 500 feet. Wiring
is non-polar.
6. Two wires from the PB Control should be attached
to the ‘PB” positions on the terminal block on the
back of the Percent Timer Control.
7. For two PB controls, one wire from each can be
twisted together and inserted into a single posi-
tion on the terminal block on the Percent Timer
Control. The wires must be a 18 gage solid wire. If
more than two PB controls are attached or 18 gage
stranded wire is used then pigtails must be inserted
into the ‘PB’ positions on the Percent Timer Control
and the leads attached to the pigtails with wire
nuts.

G. START-UP AND CHECK OUT PROCEDURE
1. Make sure power is disconnect by unplugging electri-
cal cord.
2. Check field-supplied control wiring to insure proper
installation and that all connection are tight.
3. Check field-supplied power supply for proper voltage
4. Make sure that unit is securely mounted or sus-
pended and that there are no tools or loose debris in,
around or on top of the unit
5. Check all duct connection to insure they are sealed
6. Check all duct outlets. All outlets must be open
7. Check unit filters.
8. Close unit door – plug in unit.
9. Turn all controls to off
10. Set timer to 10 %; unit should start and run for ap-
proximately six minutes.
11. Go to outside of building and check for airflow at in-
let and outlet hoods. Check that weatherhood screens
are in place and clean. Make sure that the intake
hood is positioned away from any exhausts or other
sources of pollutants. The quality of the intro-
duced fresh air is the most important function
of this system!
12. If the unit has a push-button timer installed press it
one time after the unit has cycled off from the per-
centage timer’s cycle. Unit should run twenty minutes
and then cycle off.
13. Set percent timer to recommended percentage. (See
application guide) Place peel & stick dot on the face
of the percentage timer to indicate percentage proper
setting.
14. Instruct end user on proper operation procedures and
leave use and care manual with them.
H. START-UP AND OPERATION
OPERATION - VERIFYING UNIT PERFORMANCE
1. Airflow - Airflow should be occuring in both air-
streams. 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.
2. Use Static Taps to Measure Airflow Rates - See
"Cross Core Static Drop" in MEASURING AIR-
FLOW table on page 11.
3. 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 consid-
ered balanced if the difference between the two
airflows is not more than 10 CFM.
After measuring the airflow of the unit, the bal-
anced damper may be used to balance airflow if
desired. Place the damper between the duct collar
and the unit for the inlet of the airstream record-
ing higher flow. NOTE: Install the damper so that
it slides from the door of the unit down to the duct
collar.
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.

18-HE58D1-5 11
Installer’s Guide
MEASURING AIR FLOW
1. Equipment Required -
A magnahelic guage or other device capable of mear-
suring 0 to 1.0 in. water of differential pressure.
2 pieces of natural rubber latex tubing, 1/8" ID, 1/16"
wall works 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 approximately 1 inch.
2. Cross Core Static Pressure Measurement Instruc-
tions - 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 guage drops below zero, reverse tubing connec-
tions.
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. Envirowise energy recovery ventilators
can generally operate with a flow imbalance of up
to 20% without significant loss in energy recovery
efficiency.
CAUTION
!
Make sure clean filters are installed before balanc-
ing air flow. Dirty or clogged filters reduce airflow
through the unit.
CAUTION
!
The proper airflow range for the models are:
EERVR100A1P00BA: 50-140 CFM
EERVR200A1P00BA: 100-200 CFM
