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.
ATTENTION
• 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.
NOTE
• Due to ongoing research and product
development, specifications, ratings, and
dimensions are subject to change without notice.

Thank you for purchasing a Field Control eat/Energy Recovery
Ventilator ( RV/ERV). The RV/ERV 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 RV/ERV:
• 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 Heat and Energy Recovery Ventilator (FC Series)
Optional Controls are available to adjust the amount of ventilation
in your home:
• The ealthy ome System™ Control ( SC) will automatically
deliver fresh air to your home.
• The Dehumidistat Control (D I) can be used in conjunction with
the SC to provide additional ventilation for high indoor
humidity levels.
• The Dehumidistat Ventilation Control (D VC) is a manual
control which features ON/OFF, igh speed, Low Speed, and an
electronic dehumdistat.
*Refer to the individual control pages of this manual for more
information about these controls.
Ventilation and Control Options*
igh 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. igh indoor humidity levels can result in mold and
mildew and the eventual degradation of the building structure itself.
Your RV/ERV 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
RV/ERV 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 Oper tion nd Inst ll tion M nu l 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 R 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
RV features and functions operate normally while the
dehumidistat function is disabled.
DEHUMIDISTAT RE-ENABLE - 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 RV is reset
(unplugged for 30 seconds).
How the Dehumidistat Works (Colder Climates)
DEFR ST M DE - To ensure reliable operation during cold
weather, the RV automatically cycles through its defrost mode
when the outdoor temperatures drop below freezing.
HRV/ERV - a eat Recovery Ventilator ( RV/ERV) 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 RV/ERV helps to cool the
incoming fresh air with the cool exhausted stale air.
SELF-TEST - Each time the RV/ERV is powered/energized, the
self-test function automatically initiates. The RV/ERV cycles
through the available speeds and tests the damper motor operation.
The RV/ERV defaults back to the previous operational mode and
speed selection after the self-test (approximately 60 seconds in
duration).
STANDBY - The RV/ERV is powered/energized and waiting for
ventilation to be initiated by an external control.
TIMERS - These optional controls may be installed at specific
exhaust locations (bathrooms etc.) to initiate high speed ventilation.
eat Recovery Ventilators ( RV) carry a Lifetime Warranty on the
heat recovery core and a 5 (five) year replacement parts warranty.
Energy Recovery Ventilators (ERV) carry a 5 (five) year warranty
on the energy recovery core and a 5 (five) year replacement parts
warranty.
Glossary and Additional nformation
Warranty

Your RV/ERV system produces a dehumidifying effect when
outdoor humidity levels are lower than indoor humidity levels.
These conditions occur normally when outdoor termperatures are
below 60°F. An additional dehumidification effect is achievable
with the Optional Dehumidistat (Part D 1).
The Optional D 1 Control may be combined with the ealthy
ome System Control ( SC). The D 1 will initiate high speed
ventilation when the moisture level in the home exceeds the set
point on the control. Once the humidity in the house is reduced,
the RV will revert back to the SC automatic setting. The
Dehumidistat should be set to OFF for all seasons except the
heating season.

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).
WARNING: 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 RV 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
Note: 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
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 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.
NOTE: 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 RV may accumulate dirt.
Wipe and vacuum the duct once every year. You may wish to
contact a eating/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 RV. 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 RV 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 FC95HRV
In order to make the RV as space efficient as possible, the
INDOOR supply and return ports are converted from round to oval
shape. Overall size of the port remains the same. Simply bend a
standard duct fitting to the correct shape, and attach to the oval
port using the same method as for a round port.
FC95HRV Air Flow
Stale air enters the FRONT-RIG T side port. The air passes down
the front half of the core, then up the back half of the core and out
the RIG T-REAR port.
Fresh outdoor air enters the LEFT-REAR port and passes down
the back half of the core. Then the fresh outdoor air passes up the
front half of the core and out the LEFT-FRONT port. This
configuration allows the air to actually travel through the core
twice, which makes the FC95 RV nearly as efficient as a double
core unit.

The Three Methods of nstallation
The following three installation methods are for the
RV/ERV system:
• 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/ERV 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
RV is operating to evenly distribute the fresh air
throughout the house. Refer to "Interlocking the HRV/ERV
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.
Grilles should be located high on a wall or in ceiling
locations. Grilles that diffuse the air comfortably are
recommended. Refer to "Grilles" 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/ERV &
Living Areas in the House
A well designed and installed ducting system will allow the
RV/ERV 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.
Galvanized (rigid) ducting from the RV/ERV 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 RV/ERV 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
ATTENTION
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

Key Points
• The RV/ERV must be balanced.
• It is mandatory that the furnace blower run continuously or
RV/ERV operation be interlocked with the furnace
blower. (Refer to “Interlocking the RV/ERV to an Air
andler/Furnace Blower.”)
• The duct configuration may change depending on the
RV/ERV 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/Air andler 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 RV/ERV 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.

Location
Install the unit in a heated space that provides convenient space for
service access. A typical location is in either a mechanical room or
an area close to the outside wall within close proximity to where
the weatherhoods are mounted. If a basement area is inconvenient
or non- existent, install the unit in a utility or laundry room.
Attic installations are not recommended due to:
A) the complexity of work to install
B) freezing conditions in the attic
C) difficulty of access for servicing and cleaning
Leave sufficient clearance at the front of the access door for

Drain Connection (HRV only)
Grilles
Drain Connection
The RV may produce some condensation during a defrost cycle.
This water should flow into a nearby drain, or be taken away by a
condensate pump.
The RV cabinet has prepunched holes for the drain (see below).
Insert the drain spout through the hole in the drain pan. Be sure to
install the "O ring" which seals each spout to the pan. AND
TIG TEN the washer and lock nut which hold the drain spout in
place.
Construct a P-Trap using the plastic tee connector. Cut two lengths
of 1/2" drain hose (not included) and connect the other ends to the
two drain spouts. Position the "T" fitting to point upward and
connect the drain line. Tape or fasten base to avoid any kinks. Pour
a cup of water into the drain pan of the RV after the drain
connection is complete. This creates a water seal which will
prevent odors from being drawn up the hose and into the fresh air
supply of the RV.
Adjustable grilles should be used to balance the flow rates into and
out of various rooms. The grilles should not be adjusted after
balancing the unit.
Grilles or diffusers should be positioned high on the wall or in the
ceiling. Kitchen Exhaust grilles must never be connected to the
range hood. They should be installed at least 4 feet (1.2 m)
horizontally away from the stove.
Field supplied balancing dampers should be installed external to
the unit to balance the amount of stale air being exhausted with the
amount of fresh air being brought into the house. Refer to Air flow
Balancing section.
The Techgrille
The TEC GRILLE is a round, fully adjustable grille, which
provides superior, quiet air distribution.

Weatherhood nstallation
nstalling the Ducting from the
Weatherhoods to the HRV/ERV
The inner and outer liners of the flexible insulated duct must be
clamped to the sleeve of the weatherhoods (as close to the outside
as possible) and the appropriate port on the RV/ERV. It is very
important that the fresh air intake line be given special attention to
make sure it is well sealed. A good bead of high quality caulking
(preferably acoustical sealant) will seal the inner flexible duct to
both the RV/ERV port and the weatherhood prior to clamping.
To minimize air flow restriction, the flexible insulated duct that
connects the two outside weatherhoods to the RV/ERV should
be stretched tightly and be as short as possible.
Twisting or folding the duct will severely restrict air flow.
ard (rigid) ducting which has been sealed and insulated should be
used for runs over 10’ (3.3 m). Refer to your building code.
ntake Weatherhood Requirements
• Should be located upstream (if there are prevailing winds)
from the exhaust outlet
• At least 6' (2 m) from the exhaust weatherhood
• At least 6' (2 m) away from dryer vents and furnace exhaust
(medium or high efficiency furnaces)
• A minimum of at least 6' (2 m) from driveways, oil fill pipes,
gas meters, or garbage containers
• At least 18" (460 mm) above the ground, or above the depth
of expected snow accumulation
