IMPORTANT -
PLEASE READ THIS MANUAL
BEFORE INSTALLING UNIT.
• Due to ongoing research and product
development, specifications, ratings, and
dimensions are subject to change without notice.
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.
• 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 Installation 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. If 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.

Getting to Know your Heat and Energy Recovery Ventilator (FC Series)
Thank you for purchasing a Field Control Heat/Energy Recovery
Ventilator (HRV/ERV). The HRV/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 HRV/ERV:
• Exhausts the stale, contaminated air, found in today’s tight
buildings.
Ventilation and Control Options*
Optional Controls are available to adjust the amount of ventilation
in your home:
• The Healthy Home System™ Control (HHSC) will automatically
deliver fresh air to your home.
• The Dehumidistat Control (DHI) can be used in conjunction with
the HHSC to provide additional ventilation for high indoor
humidity levels.
How the Dehumidistat Works (Colder Climates)
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/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
HRV/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 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.
• 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.
• The Dehumidistat Ventilation Control (DHVC) is a manual
control which features ON/OFF, High speed, Low Speed, and an
electronic dehumdistat.
*Refer to the individual control pages of this manual for more
information about these controls.
Refer to the main control instructions located in the Operation and
Installation Manual 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-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 HRV is reset
(unplugged for 30 seconds).
Glossary and Additional Information
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/ERV - a Heat Recovery Ventilator (HRV/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 HRV/ERV helps to cool the
incoming fresh air with the cool exhausted stale air.
Warranty
Heat Recovery Ventilators (HRV) 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
SELF-TEST - Each time the HRV/ERV is powered/energized, the
self-test function automatically initiates. The HRV/ERV cycles
through the available speeds and tests the damper motor operation.
The HRV/ERV defaults back to the previous operational mode and
speed selection after the self-test (approximately 60 seconds in
duration).
STANDBY - The HRV/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.
on the energy recovery core and a 5 (five) year replacement parts
warranty.

Healthy Home System Control (HHSC)
Th e H ea lt hy Home Sy st em Control ( HH SC) a ct iv at es the
HRV/ERV automatically to deliver fresh air into your home.
Setting the Control
The duration of the ventilation rate is adjustable on the HHSC.
Your installer sets up this control during the installation of your
system . Refer to the instructions that came with the HHSC for the
setup information.
Dehumidistat (Part DH1)
The Healthy Home System™ Control (HHSC)
Your HRV/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 DH1).
The Optional DH1 Control may be combined with the Healthy
Home System Control (HHSC). The DH1 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 HRV will revert back to the HHSC automatic setting. The
Dehumidistat should be set to OFF for all seasons except the
heating season.

Maintenance Routine for HRV
Electric shock hazard. Can cause
injury or death. Before attempting to
perform any service or maintenance,
turn the electrical power unit OFF at
disconnect switch(es). Unit may have
multiple power supplies.
WARNING
1. Inspect 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: Blockage of hoods may cause an imbalance.
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
Note: Core installation label 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) mo unt t he left or ri ght s id e fla ng e of th e cor e 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.
NOTE: Core will appear to stick out from cabinet approximately 1/8”
(3mm). This is designed this way so that the access door will fit tight
against the core.
4. Motors - Maintenance Free
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 ma y oc cur peri odically after that ov er 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 lar ge o pe ning of the fan
assembly and then
(b) th rough the sma ll er o pe ning 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 attempting this task, thought should be given to having a
qualified service technician complete the service work.
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.

Port Configuration and Airflow Model FC95HRV
In order to make the HRV 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.
Round port bent to oval
FC95HRV Air Flow
Stale air enters the FRONT-RIGHT side port. The air passes down
the front half of the core, then up the back half of the core and out
the RIGHT-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 FC95HRV nearly as efficient as a double
core unit.
