PLEASE READ TH S MANUAL
BEFORE NSTALL NG UN T.
CAUTION
Before installation, careful consideration must be
given to how this system will operate if connected
to any other piece of mechanical equipment, i.e. a
forced air furnace or air handler, operating at a
higher static. After installation, the compatibility of
the two pieces of equipment must be confirmed, by
measuring the air flows of the HRV, by using the
balancing procedure found in this manual.
NEVER install a ventilator in a situation where its
normal operation, lack of operation or partial
failure may result in the backdrafting or improper
functioning of vented combustion equipment.
WARNING
• Disconnect the power from the unit before
cleaning or servicing.
• To prevent electrical shock, it is extremely
important to confirm the polarity of the power line
that is switched by the safety (disconnect) switch.
The hot line (black) is the proper line for switching.
Use either a voltmeter or test lamp to confirm the
absence of a voltage between the disconnect
switch and ground (on the cabinet) while the door
is open. This procedure must be followed, as
dwellings are occasionally wired improperly.
Always enure the proper grounding of the unit.
• Do not apply electrical power to the unit until after
the completion of the installation (including the
installation of low voltage control wiring).
• Ensure the nstallation and wiring is in
accordance with CEC, NEC, and local electrical
codes.
• Due to ongoing research and product
development, specifications, ratings and
dimensions are subject to change without notice.
•Plug the unit into a standard designated (120 VAC)
electrical outlet with ground.
•The use of an extension cord with this unit is not
recommended. f the installation requires further
wiring, have a licensed electrician make all of the
electrical connections. The recommended circuit is a
separate 15 amp/120 volt circuit.
• Due to ongoing research and product
development, specifications, ratings and
dimensions are subject to change without notice.

Thank you for purchasing a LIFEBREATH® Heat Recovery Ventilator
(HRV). The HRV provides fresh air to your home while recovering
energy from the air it exhausts.
There are numerous benefits to a properly installed, operated, and
maintained HRV:
• exhausts the stale, contaminated air, found in today’s tight buildings.
• recovers the majority of the energy contained in the exhausted stale air.
• uses the recovered energy to preheat or precool the fresh outdoor air
introduced into the house
.• distributes the fresh air throughout your home.
Getting to Know your RNC Series Heat Recovery Ventilator (HRV)
Your Lifebreath RNC SERIES HRV has several optional controls.
Experiment with the ventilation levels in your home to evaluate the ideal
amount of ventilation to suit your home and personal preferences.
. CONT NUOUS VENT LAT ON
This mode of operation provides continuous ventilation within the home.
You may, for example, select Continuous Ventil tion at a low speed (speeds
1 or 2) for normal operation and increase to a higher speed (speeds 3 to 5)
during increased activity levels, such as cooking and showering, etc.
. 20 M NUTES ON, 40 M NUTES STANDBY
This mode of operation provides 20 minutes of ventilation each hour. You
can use this ventilation mode at low speed for low household
activity levels or when the home is unoccupied. This feature is
unavailable on some controls.
. 20 M NUTES ON, 40 M NUTES REC RCULAT ON *
Ventilates for 20 minutes and recirculates the household air every
40 minutes each hour. This mode is non-applicable if your HRV is
connected to a forced air system (the forced air system already circulates
household air).This feature is unavailable on some controls.
V. CONT NUOUS REC RCULAT ON *
Continuously recirculates your household air (no ventilation). This mode is
non-applicable if your HRV is connected to a forced air system.This feature
is unavailable on some controls.
* If your HRV is connected to a forced air system, recirculation (modes III
and IV) is unavailable and non-applicable on all models.
REC RCULAT ON - recirculates existing household air without
introducing fresh air. Recirculation Modes (III and IV) are
non-applicable if your HRV is connected to a forced air system, since your
forced air system already circulates the household air. Recirculation Modes
are unavailable on some models.
Selecting the Ventilation Rate that is right for You
High indoor humidity levels, during the heating season, have become a
problem in many well insulated, tight homes. Excessive condensation on the
windows is a visual sign of high indoor humidity levels. High indoor
humidity levels can result in mold and mildew and the eventual
degradation of the building structure itself.
Your HRV reduces indoor humidity levels when the outdoor air is drier
than the indoor air. These conditions usually occur during the
heating season when outdoor temperatures are less than 15°C (59°F). During
the heating season, the operation of the HRV may reduce indoor humidity
levels sufficiently to eliminate the need for further dehumidification.
If your home requires further dehumidification, use the dehumidistat
feature located on any optional main control (refer to the Operation and
Installation Manual for Optional Control information). This feature
aggressively addresses high indoor humidity levels by initiating high speed
ventilation when the indoor humidity levels rise above the
adjustable set point on the control.
Refer to the main control instructions located in the Oper tion nd
Inst ll tion M nu l for instructions on how to set the dehumidistat.
The dehumidistat function on the main control should be set to OFF for all
seasons except the heating season, because a dehumidifying effect
occurs only when the outdoor air is dryer than the indoor air. Set the RH
level to 80 to turn the dehumidistat OFF. (Refer to the control
instructions for information on how to set the Dehumidistat).
DEHUMIDISTAT DISABLE - automatically disables the dehumidistat
function on the main control when outdoor temperatures exceed 15°C
(59°F) for a full 24 hour period. All other HRV features and functions
operate normally while the dehumidistat function is disabled.
DEHUMIDISTAT RE-E ABLE - automatically re-enables the
dehumidistat function if either the outdoor temperature drops below 15°C
(59°F) for a full 24 hour period or if the HRV is reset (unplugged for
30 seconds).
How the Dehumidistat Works
DEFROST MODE - To ensure reliable operation during cold weather, the
HRV automatically cycles through its defrost mode when the outdoor
temperatures drop below freezing.
HRV - a Heat Recovery Ventilator (HRV) is designed to provide fresh air
into a building while exhausting an equal amount of stale air. During the
winter months, heat recovered from the stale air, before it is
exhausted to the outdoors, warms the incoming cold fresh air. During the
summer months, when the indoor space is air conditioned, the HRV helps to
cool the incoming fresh air with the cool exhausted stale air.
MAI TE A CE ROUTI E - Homeowner maintenance should be
performed as per "M inten nce Routine for HRV" located in the
Oper tion nd Inst ll tion M nu l.
OPTIO AL CO TROLS - A selection of Optional Controls is available
for the HRV. Refer to the Operation and Installation Manual for more
information.
OPERATIO A D I STALLATIO MA UAL - Contains
instructions and important information regarding your HRV and controls.
You can download the manual at www.lifebreath.com.
SELF-TEST - Each time the HRV is powered/energized, the self-test
function automatically initiates. The HRV cycles through the available
speeds and tests the damper motor operation. The HRV defaults back to the
previous operational mode and speed selection after the self-test
(approximately 60 seconds in duration).
STA DBY (Speed 0) - The HRV is powered/energized and waiting for
ventilation to be initiated by either an external control (i.e. timer) or the
dehumidistat. Set the main control to speed 0 to set the HRV in standby.
TIMERS - These optional controls may be installed at specific exhaust
locations (bathrooms etc.) to initiate high speed ventilation.

1. nspect Exterior Hoods at least once a month.
Make sure exhaust and fresh air supply hoods are not blocked or
restricted by leaves, grass, or snow. In winter, it is especially
important to make sure snow is not blocking the hoods or that frost
has not built up on the wire mesh (bird screen).
WARIG: Block ge of hoods m y c use n imb l nce.
2. Clean Air Filters (clean twice a year)
The standard filters equipped with your HRV are removable and
washable.
a) simply open access door and slide core out
b) remove filter clips
c) once clips are removed filters can be taken off the core to be
rinsed with water or a combination of mild soap and water. Do
not clean in the dishwasher
d) to re-assemble, place clean filter(s) (wet or dry) back into their
positions against the core and return clips to their original
position
e) slide core back into its’ original position
3. Clean Core Twice a Year
a) open access door.
b) carefully grip ends of core and pull evenly outward. Core may
be snug, but will slide out of the channel
c) once removed from the cabinet remove filters
d) wash core in warm soapy water (do not use dishwasher)
e) install the clean filters
f) install clean core
ote: Core inst ll tion l bel on the outer end of the core.
To install the clean core:
a) first mount the bottom flange of the core guide into the bottom
H channel approximately 1/4” (6mm)
b) mount the left or right side flange of the core guide
approximately 1/4” (6mm) followed by the other side
c) mount the top flange of the core guide into the top H channel
approximately 1/4” (6mm).
d) with all four corners in place and the core straight and even,
push hard in the centre of the core until the core stops on the
back of the cabinet.
OTE: Core will ppe r to stick out from c binet pproxim tely 1/8”
(3mm). This is designed this w y so th t the ccess door will fit tight
g inst the core.
4. Motors - Maintenance Free
5. Drain (condensate) Line - Clean once a year
Inspect drain line, drain spout and “P” trap for blockage, mould or
kinks. Flush with warm soapy water and replace if worn, bent or
unable to clean.
6. Clean Duct Work if Required
The duct work running to and from the HRV may accumulate dirt.
Wipe and vacuum the duct once every year. You may wish to
contact a Heating/Ventilation company to do this.
7. General Maintenance - Twice a Year
Wipe down the inside of the cabinet with a damp cloth to remove
dirt, bugs and debris that may be present.
8. Cleaning the Fans
Fans may accumulate dirt causing an imbalance and/or excessive
vibration of the HRV. A reduction in the air flow may also occur.
In new construction this may result within the first year due to
heavy dust and may occur periodically after that over time
depending on the outdoor conditions.
• unplug the HRV and open the service door
• remove the core
• remove ducting (metal and/or flexible insulated type) from
the red and/or blue ports which are connected immediately
in-line with the fan assembly
• use a small brush, such as an old toothbrush or pipe cleaner,
and insert first
(a) through the large opening of the fan
assembly and then
(b) through the smaller opening in the end
of the fan assembly.
• scrub individual fan blades until clean. Avoid moving or
damaging balancing flat weight, clip is usually found on one
or more of the fan blades
• vacuum and wipe
• reassemble making sure ducting is reattached firmly and
insulation and moisture barrier are sealed and taped
Before ttempting this t sk, thought should be given to h ving
qu lified service technici n complete the service work.

Port Configuration and Airflow Model RNC95
RNC95 Port Specifications
The RNC95 Heat Recovery Ventilator (HRV) has been designed
to allow the installer to choose between two possible positions on
the cabinet for the INDOOR EXHAUST (return from building)
port. Illustrations in this manual show standard (side mounted)
port location. The same specifications apply to both RNC95
setups, regardless of which port position is selected.
Variable Port Location / nstallation
(Model RNC95 only)
The exhaust return port collar is not factory installed. Installer
may choose either side mounted or alternate top mounted port by
simply removing one of the two knock-out plates and attaching a
port collar (supplied). To remove knock-out plate, insert a utility
knife into the knock-out slits and trace them completely to
puncture protective film underneath. Then, cut the solid tabs
between the slits, using tin snips or side cutters, and remove the
knock-out plate. If any protective film still blocks the opening,
remove it now.
In order to make the RNC95 as space efficient as possible, the
INDOOR supply and return ports are converted from round to oval

standard duct fitting to the correct shape, and attach to the oval
port using the same method as for a round port.
RNC95 Air Flow
Stale air enters the FRONT RI HT side port. The air will pass
down the front half of the core, then up the back half of the core
and out the RI HT REAR port.
Fresh outdoor air will enter the LEFT REAR port and pass down
the back half of the core. It will then pass up the front half of the
core, and out the LEFT FRONT port. This unique configuration
allows the air to actually travel through the core twice, making the
RNC95 almost as efficient as a double core unit.

The HRV can be installed horizontally or vertically as
illustrated on the following pages. The unit should be
suspended using the provided hanging straps. The unit
must be level for proper condensate drainage.
Sufficient clearance below the access door is required for
servicing the air filters and core. A minimum of 25"
(635mm) clearance is recommended so the door can be
removed. Four PVC reinforced polyester hanging straps are
provided for hanging the HRV.

The Three Methods of nstallation
The three methods of installation for the HRV system are:
• The Simplified installation.
• The Partially Dedicated Installation
• The Fully Dedicated Installation
Simplified nstallations
The Simplified Installation draws stale air from the cold air return
duct of the air handler/furnace and introduces an equal amount of
fresh air farther downstream into the cold air return. Refer to
"Simplified Inst ll tion Di gr ms".
The air handler/furnace blower must be running when the unit is
operating for this system to be effective. Refer to "Interlocking the
HRV to n Air h ndler/Furn ce Blower".
Partially Dedicated nstallations
The Partially Dedicated Installation draws stale air from specific
points in the house and introduces an equal amount of fresh air into
the cold air return. Refer to "P rti lly Dedic ted Inst ll tion
Di gr ms".
Stale air ducts should be installed in areas of the home where the
poorest indoor air quality exists (bathrooms and kitchen). Each
location with a stale air duct should have a timer to initiate high
speed ventilation. Refer to "Option l Timers" in this manual.
The air handler/furnace blower should be running when the HRV
is operating to evenly distribute the fresh air throughout the house.
Refer to "Interlocking the HRV to n Air h ndler/Furn ce
Blower".
Fully Dedicated nstallations
The Fully Dedicated Installation draws stale air from specific
points in the house and delivers fresh air to specific locations of the
house. This system is not connected to an air handler/furnace.
Refer to "The Fully Dedic ted Inst ll tion Di gr ms" in this
manual.
Stale air ducts should be installed in areas of the home where the
poorest indoor air quality exists (bathrooms and kitchen). Each
location with a stale air duct should have a timer which will initiate
high speed ventilation. Refer to "Optional Timers" in this manual.
Fresh air ducts should be installed to all bedrooms and living areas,
excluding bathrooms, kitchen and utility areas. rilles should be
located high on a wall or in ceiling locations. rilles that diffuse
the air comfortably are recommended. Refer to " rilles" in this
manual. Special care should be taken in locating grilles if the floor
is the only option available. Areas such as under baseboard heaters
will help to temper the air.
Optional in-line duct heaters are available for mounting in the
supply duct work to add heat if required.
nstalling the Ducting Between the HRV & Living
Areas in the House
A well designed and installed ducting system will allow the HRV
to operate at its maximum efficiency.
All ducts should be kept short and have as few bends or elbows as
possible to maximize airflow. Forty-five degree elbows are
preferred to 90° elbows. Use "Y" tees instead of straight tees
whenever possible.
All duct joints must be fastened with screws, rivets or duct sealant
and wrapped with mastic or quality duct tape to prevent leakage.
Mastic is preferred but if duct tape is used, we recommend
aluminum foil duct tape.
alvanized (rigid) ducting from the HRV to the living areas in the
house is recommended whenever possible although flexible duct
can be used in moderation if necessary.
A short length (approximately 12 inches or 300mm) of non-
metallic flexible insulated duct should be connected between the
HRV and the supply/exhaust duct system to avoid possible noise
transfer through the duct system.
All ducts running through attics and unheated spaces must be
sealed and insulated to code.
nstallation Methods
Applications such as greenhouses, atriums,
swimming pools, saunas, etc. have unique
ventilation requirements which should be
addressed with an isolated ventilation system.

DIRECT CONNECTION of both the HRV SUPPLY AIR STREAM and
EXHAUST AIR STREAM to the FURNACE COLD AIR RETURN
Installation Notes
• Unit is normally balanced on HIGH speed with the furnace blower ON.
• A minimum separation of 40 inches (1m) is recommended between the
two direct connections.
• The exhaust air connection should be upstream of the supply air
connection to prevent exhausting any fresh air.
• Weatherhood arrangement is for drawing purposes only. Six feet (2m)
minimum separation is recommended. The Weatherhood must also be 18"
(460mm) above grade minimum.
• The airflow must be confirmed on site using the balancing procedures found in this manual
Spring-Loaded Backdraft Damper
Install the Backdraft Damper with the leaf hinge vertical.
The damper is installed on the “Stale Air to Outside Collar”.

The Stale Air to Outside air duct requires
a Backdraft Damper. This damper prevents
outdoor air from entering the HRV
during the operation of the Furnace/
Airhandler while the HRV is in standby,
OFF or Recirculate.

Key Points
• The HRV must be balanced.
• It is mandatory that the furnace blower run continuously
or HRV operation be interlocked with the furnace blower.
(Refer to “Interlocking the HRV to an Air
Handler/Furnace Blower.”)
• The duct configuration may change depending on the
HRV model. See specifications for your unit.
• Check local codes / authority having jurisdiction for
acceptance.
• A backdraft damper is required in the exhaust air duct to
prevent outdoor air from entering the unit when the
Furnace/Airhandler is running and the unit is in Standby,
OFF or Recirculate.
Sizing the Ductwork
It is the responsibility of the installer to ensure all ductwork
is sized and installed as designed to ensure the system will
perform as intended.
The amount of air (cfm) that an HRV will deliver is directly
related to the total external static pressure (E.S.P.) of the
system. Static pressure is a measure of resistance imposed on
the blower by length of duct work plus the number of fittings
used in the duct work.
