HRV ducting for fully Dedicated System
INSTALLATION EXAMPLES
Example only – duct configuration may differ depending on the model.
FULLY DEDICATED SYSTEM
BEST FOR NEW CONSTRUCTION
1. Stale air is drawn from key areas of the home requiring local exhaust
(bathroom, kitchen, laundry room).
2. Fresh air is distributed directly to habitable rooms in the house
(bedrooms, living room)
3. The HRV’s airflow must be balanced after installation using the procedure
found in the section “AIRFLOW BALANCING”
Suggested installation for:
• Hydronic baseboard
• Inoor heating
• Electric baseboard
• Mini split heat pump
Benets: Provides the best
fresh air distribution in the
house; lowest operation cost
since the furnace/air handler
unit is not needed.

PARTIALLY DEDICATED SYSTEM (BETTER)
Suggested installation for:
• Central furnace (air
handling unit or central
air conditioners)
• When ducting fresh
air to living area is not
possible or practical,
i.e. expensive or when
the central AHU will
operate year-round.
Benets: Conditions the
fresh air prior to
distributing it throughout
the house
1. In order to provide proper distribution of the fresh air, it is
recommended that the furnace blower be set to run continuously or
interconnected with HRV. See furnace electrical connection on
page 16.
2. Stale air is drawn from key areas of the home (bathroom, kitchen,
laundry room).
3. Fresh air is supplied to the return air plenum of the furnace.
4. Due to the difference in pressure between the HRV and the
equipment it is being connected to the HRV’s airflow must be
balanced on site, using the procedure found in the section “AIRFLOW
BALANCING”
* In the case of a multi-zone system, please contact Fantech customer
service prior to installing any installation type requiring the use of the
furnace interlock"
Make sure the HRV is

EXTERIOR DUCTING INSTALLATION
WEATHERHOOD LOCATION
• Decide where your intake and exhaust hoods will be located.
Locating the Intake Weatherhood
• Should be located upstream (if there are prevailing winds) from the
exhaust outlet.
• At a minimum distance to 900 mm (3') away from dryer vents and furnace
exhaust (medium or high efficiency furnaces), driveways, oil fill pipes, gas
meters, or garbage containers.
• At a minimum height of 460mm (18’’) above the ground, or above the level
of expected snow accumulation.
• Ideally, keep weatherhoods 1m (3') from corners.
• Do not locate in the garage, attic, crawl space, or underneath deck.
Locating the Exhaust Weatherhood
• At least 460mm (18") above ground or above the depth of expected snow accumulation
• Ideally, keep weatherhoods 1m (3') from corners.
• Not near a gas meter, electric meter or a walkway where fog or ice could create a hazard
• Do not locate in a garage, workshop or other unheated space
INSTALLING THE DUCTING TO THE WEATHERHOODS
A well designed and installed ducting system will allow the HRV to operate at its
maximum efficiency. The inner liner of the flexible insulated duct must be secured to the
sleeve of the weatherhood (as close to the outside as possible) and to the appropriate duct
connection on the HRV. The insulation should remain full and not crushed. The outer liner,
which acts as a vapor barrier, must be completely sealed to the outer wall and the HRV
using tape and/or caulking. A good bead of high quality caulking (preferably acoustical
sealant) will seal the inner flexible duct to both the HRV duct connection and the
weatherhood prior to securing them.
To minimize airflow restriction, the flexible insulated duct that connects the two outside
weatherhoods to the HRV should be stretched tightly and be as short as possible.
Twisting or folding the duct will severely restrict airflow.
See “Installation Diagram Examples” for installation examples.
1Using the duct connection of
the outside hood, outline the
intake & exhaust holes to be
cut. The holes should be slightly
larger than the duct connection
to allow for the thickness of the
insulated flexible duct. Cut a
hole for both the intake and
exhaust hoods.
3 Push the hood into the opening
and then attach the hood to the
outside wall with mounting
screws.
Repeat the installation
procedure for both the supply
and exhaust hoods.
2Pull the insulated flexible duct
through the opening until it is
well extended and straight.
Slide the duct’s inner vinyl sleeve
over the hood duct connection
and secure. Pull the insulation
over the duct and pull the vapor
barrier over the sleeve. Secure
with appropriate tape or
sealant.
4Using a caulking gun, seal
around both hoods to prevent
any leaks.

INTERIOR DUCTING INSTALLATION
•To maximize airflow through the ductwork system, all ducts should be kept short and have as few bends or elbows as possible.
•45º elbows are preferable to 90º.
•Use “Y“ ducts instead of “T” ducts whenever possible.
•All duct joints must be fastened with screws or duct sealant and wrapped with aluminum foil duct tape to prevent leakage.
•Galvanized ducting from the HRV to the living areas in the house is recommended whenever possible, although flexible ducting
can be used in moderation when necessary.
•To avoid possible noise transfer through the ductwork system, a short length (approximately 300 mm, 12’’) of nonmetallic flexible
insulated duct should be connected between the HRV and the supply/exhaust ductwork system.
•The main supply and return line to/from the HRV must have the same diameter as the duct connection or larger.
•Branch lines to the individual rooms may be as small as 100 mm (4’’).
Installing ducting to HRV
For flexible duct installation, slide flexible ducting onto duct connection. Then install a
cable tie over flexible duct to prevent leakage between the ducting and the duct
connection.
In the case of solid ducting, slide duct over duct connection, screw in place and seal.
Supply air grilles location
In homes without a forced air furnace, fresh air should be supplied to all habitable rooms, including bedrooms and living areas. It should be supplied
from high wall or ceiling locations. Grilles that diffuse the air comfortably are recommended. In homes with a forced air furnace, you may want to connect
the HRV to the furnace ductwork (see information below).
Exhaust air grilles location
The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is recommended that return
air ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations may be installed. The furnace
return duct may also be used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the HRV with
“dedicated lines”.
Ducting fifth port
The SHR 260RD has a 5th port on top. This duct port is for both the defrost and recirculation modes. A motorized damper installed in the port closes
during defrost or recirculation, temporarily blocking the incoming fresh air-stream, allowing the warm air from the house to circulate through the HRV.
You may wish to duct this port to a common room with clean air (living room or dining room), so when the recirculation mode is activated, household
odors from the kitchen, bathroom or basement won’t be introduced into the living spaces of the home environment.
As per building codes and installation requirements for combustion appliances:
Air return ducts, or openings for air return, should not be placed in enclosed spaces containing combustion
appliances that are subject to spillage.

10
HRV INSTALLATION
LOCATION
The HRV must be located in a conditioned space where it will be possible to conveniently service the unit. Typically
the HRV would be located in the mechanical room or an area close to the outside wall where the weatherhoods will
be mounted. If a basement area is not convenient or does not exist, a utility room may be used.
Attic installation must meet the following conditions:
• Attic temperature must be above freezing conditions at all times and for best performance should be 12°C
(54 °F).
• The condensate drain (if included) must be installed so that the condensate drains and is protected from freezing.
• The attic is easily accessible for equipment maintenance and inspection.
Connecting appliances to the HRV is not recommended. These include:
• Clothes dryer
• Range top
• Stovetop fan
• Central vacuum system
• Bathroom exhaust fans unless they are specifically designed for this purpose
These appliances may cause lint, dust or grease to collect in the HRV, damaging the unit.
Connecting any of these types of appliances to the
HRV will void your warranty.
Mounting- Chain mount
• Have a nearby power supply
(120 volts, 60Hz)
• Choose a location which
allows the possibility
of mounting the unit to
supporting beams.
• The unit should be level
in order to allow proper
condensate drainage
• To minimize noise, do not
install unit in living area
• Ensure proper drainage
1 Place fastening hooks on
the strapping board or
the oor joists.
2 Attach a hanging chain
(provided) to each 19 mm
(3/4") bolt (provided) in the
top 4 corners of the unit
and tighten.
4 Install a spring on each
chain. Hook the spring
in the links so a loop is
created in the chain. The
spring will then support the
unit's weight and absorb
vibrations.
3 Hang the unit by slipping
a link onto the hanging
hooks, making sure the
unit is level.

11
Start up procedure
The Switch on the side of the unit is used to toggle between STANDBY, REDUCED speed and NORMAL speed modes.
Place the unit in NORMAL speed to perform the balancing.
Airflow balancing
IF THE UNIT'S AIR FLOWS ARE NOT PROPERLY BALANCED...
•THE UNIT'S EFFICIENCY MAY BE REDUCED.
•THE UNIT'S CORE MAY BECOME DAMAGED.
•NORMAL OPERATION OF THE UNIT COULD CAUSE THE PRESSURIZATION OR DEPRESSURIZATION OF YOUR
HOME, WHICH CAN LEAD TO AIR LEAKS OR BACKDRAFTING OF ANY COMBUSTION APPLIANCES.
The balancing procedure consists of measuring the supply air flow and the return air flow to ensure that they are equal. A difference of up to 10% is
considered acceptable. In the cases where the air flow is not exactly the same, it is recommended to have a higher return air flow to ensure that the
temperature of the supply air flow coming from outside is as close to room temperature as possible.
•For optimal performance, HRV unit should be re-balanced after a major renovation or after the
installation of extra grilles or registers.
1 Remove the nutsert.
INSTALLING DRAIN LINE
Through normal operation and during its defrost mode, the HRV may produce some condensation. This water should flow into a nearby drain, or be taken
away by a condensate pump. The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point.
A “P” trap should be made in the drain line. This will prevent odors from being drawn back up into the unit.
2 Invert the drain nipple. Make
sure to place gasket between
the unit and the drain nipple
inside the unit.
3 Secure the drain nipple using
the nutsert.
4 Install the drain hose making a
"P" trap, secure the
condensate line drain
connection using the tube
clamp provided.
Fill the condensate line with
water.
The drain nipple is placed upside down in the unit to prevent it being damaged during shipping or the installation of the unit.

12
Airflow balancing (Cont'd)
1Cut hole in duct and insert flow measuring
station. Make sure that the flow measuring
station’s air direction arrow points in the
direction of the airflow. Secure the flow
measuring station with duct tape.
2Before taking the reading, make sure that
the magnehelic gauge is level and at 0.
Refer to the flow measuring station’s
chart to determine your unit’s airflow
velocity.
3Adjust the “Supply Air Out” damper until
you reach the desired velocity. Follow
steps 1-3 to adjust the “Exhaust Air Out”
damper, if needed.

• To avoid airflow turbulence and incorrect
readings, the airflow velocity should be
measured on a section of steel ducting.
Reading should also be taken at a minimum
distance of 457 mm (18") from the unit or
elbow. Measurement should also be made
prior to any transition in the duct work so
entire airflow is measured.
Measuring the airflow using station (grid) method
Adjusting airflows
A damper is integrated into the Fresh Air to Building collar. This damper replaces the installation of a separate
damper into the Fresh Air to Building ducting line.
The damper-collar is pre-set in the fully opened position. If the procedure requires a reduction in airflow to
the fresh air duct, simply turn positioning knob located on the side of the collar clockwise until desired airflow
is obtained. The damper position can be determined by the orientation of the pointers situated on the side of
the damper. The damper is fully open when the pointers are towards the top of the collar (as shown in picture)
and fully closed when they are sideways.
Once procedure is completed, install a piece of tape over positioning knob to avoid any tampering by the home owner.
WARNING! DO NOT TURN POSITIONING KNOB COUNTERCLOCKWISE WHEN DAMPERS ARE FULLY OPENED AS DAMAGE MAY OCCUR

Note Avertissement/
Note importante Information Information technique Conseil pratique
VEUILLEZ LIRE ET CONSERVER CES INSTRUCTIONS
Avant de procéder à l’installation, examinez avec soin la façon dont le système fonctionnera s’il est relié à tout
autre appareil mécanique, notamment une fournaise à air pulsé ou un appareil de traitement d’air dont la pression
statique est plus élevée. Une fois l’installation terminée, la compatibilité des deux appareils doit être conrmée en
mesurant le débit d’air du ventilateur récupérateur de chaleur (VRC) au moyen de la procédure d’équilibrage du
présent manuel. Il importe de toujours évaluer l’interaction du VRC avec les appareils de chauffage à évacuation
(fournaise à gaz, fournaise à mazout, poêle à bois, etc.)
Les produits sont conçus et fabriqués pour fournir une performance able, mais ils ne sont pas garantis à 100%
sans défaut. Même les produits ont des pannes occasionnelles et cette possibilité devrait être reconnue par
l'utilisateur. Si ces produits sont utilisés dans un système de ventilation qui maintien des fonctions vitales où une
défaillance pourrait entraîner des pertes ou des blessures, l'utilisateur doit fournir une ventilation de secours
adéquate, une ventilation supplémentaire naturelle, un système d'alarme de défaillance ou d'accepter les risques
de pertes ou de blessures.
Votre système de ventilation doit être installé en conformité avec le code du bâtiment local qui est en vigueur, en
l’absence de telles exigences, il est recommandé de vérier auprès des autorités locales ayant juridiction dans
votre région avant d’installer ce produit.
