PLEASE READ AND SAVE THESE INSTRUCTIONS

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 pressure. After installation, the compatibility of the two pieces of equipment must be conrmed

by measuring the airow of the Fresh Air Applliance using the balancing procedure found in this manual.

It is always important to assess how the operation of any FAA may interact with vented combustion equipment (i.e.

Gas Furnaces, Oil Furnaces, Wood Stoves, etc.)

Products are designed and manufactured to provide reliable performance, but they are not guaranteed to be 100%

free of defects. Even reliable products will experience occasional failures, and this possibility should be recognized

by the user. If these products are used in a life support ventilation system where failure could result in loss or injury,

the user should provide adequate back-up ventilation, supplementary natural ventilation or failure alarm system, or

acknowledge willingness to accept the risk of such loss or injury.

Your ventilation system should be installed in accordance with the local building code that is in effect, in absence

of such requirements, it is recommenced to check with local authorities having jurisdiction in your area prior to

installing this product.

* ASHRAE 62.2-2016 Table 4.1, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings.

Bathroom: If the FAA is going to provide the required local exhaust ventilation for each bathroom with each a continuous 20 CFM

(10 L/s), this ventilation rate can be considered as part of the whole-building ventilation rate.

INSTALLATION EXAMPLES

The way your heat/energy-recovery ventilator is installed can make a significant difference to the electrical

energy you use. To minimize the electricity use of the heat/energy-recovery ventilator, a stand-alone fully

ducted installation is recommended. If you choose a simplified installation that operates your furnace air

handler for room-to-room ventilation, an electrically efficient furnace that has an electronically commutated

(EC) variable speed blower motor will minimize your electrical energy consumption and operating cost.

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 FAA’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.

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 FAA. 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 FAA and the equipment

it is being connected to the FAA'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

Fantech fresh air applicance (FAA or HRV/ERV) that use a supply fan shutdown for frost

prevention do not include an outdoor air motorized damper. If you are using a simplied

installation, i.e. connecting the FAA supply air duct to a furnace's return air duct, the FAA

must operate continuously. When the FAA is turned off, no warm exhaust air will ow

through the FAA but the furnace's fan will continue to draw in outdoor air directly into the

furnace. If it's cold outside, cold air will be introduced, without re-heating, directly into

the furnace.

If the FAA is installed such that the homeowner may turn off the FAA during the winter, we

recommend installing a motorized damper between the FAA's supply air and the furnace's

return air duct that closes when the FAA is not operating. See wiring diagram (gure 1).

You may also choose to use a Fantech FAA that uses a recirculation defrost that incorpo-

rates an outdoor air damper.

2. A minimum separation of 1m (39’’) is recommended between the two direct

connections.

3. In order to prevent exhausting any fresh air, the FAA's exhaust air connection should be

upstream of the FAA's supply air connection when ducting to the furnace’s cold air return.

4. Due to the difference in pressure between the FAA and the equipment it is being

connected to the FAA's airflow must be balanced on site, using the procedure found in the

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 FAA 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 FAA. 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 FAA

using tape and/or caulking. A good bead of high quality caulking (preferably acoustical

sealant) will seal the inner flexible duct to both the FAA 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 FAA 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.

1 Using 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.

2 Pull 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.

4 Using 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 FAA 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 FAA and the supply/exhaust ductwork system.

• The main supply and return line to/from the FAA 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 FAA

Warning: Always fix and secure the 6" collars with the screws supplied. Avoiding this critical step the unit will accumulate condensation.

Tip to Installer: To ensure a better installation and to avoid an undesired bend in the duct, align the duct with the collar before securing over the four

hooks.

The fresh air from outside and the Exhaust air to outside from the termination ducts to the FAA must be fully insulated of thermal insulation ducts to

minimize heat loss and gain. All tapes, mastics, and nonmetallic clamps used for field installation of flexible ducts shall be listed and labeled to Standard

UL 181B - Closure Systems for Use With Flexible Air Ducts and Air Connectors.

Air Connector A category of flexible duct not meeting the requirements of an Air Duct per UL 181 Standard (not tested for flame penetration, puncture

and impact) and having limitations on use, length and location as defined by NFPA 90A and 90B. Air Connectors are identified by a “round shape” listing

label of the listing agency.

Air Duct A category of flexible duct tested and classified as to the Surface Burning Characteristics in accordance with the UL 181 Standard. Air Ducts

are identified by a “rectangular shape” listing label of the listing agency.

To ensure quiet operation of ENERGY STAR qualified FAA, each product should be installed using sound attenuation techniques appropriate for the

installation. Once insulated flex is attached to the collar, slide collar in keeper section, fixed collar to the unit with four screws supplied in installation

kit to insure a proper seal.

Warning: To reduce air leakage in the final installation always seal the joint between all collars and keepers with aluminum tape or mastic.

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 FAA 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”.

Insert vinyl duct over the hooks

and seal with a Tie wrap

Insert insulation inside the double

collar.

Finish by taping the vapor

barrier to the collar to insure

proper seal.

Slide collar on the unit. Fix and secure with four screws supplied

and seal all joints.

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.

FAA INSTALLATION

LOCATION

The FAA must be located in a conditioned space where it will be possible to conveniently service the unit. Typically

the FAA 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 FAA 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 FAA, damaging the unit.

Connecting any of these types of appliances to the

FAA 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 Take at screwdriver and

slightly pull on punched out

tab. Put chain link under

hook.

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.

INSTALLING DRAIN LINE

Insert the threaded drain adapter thru the bottom of the FAA and hand tighten the plastic nut, and with a wrench tighten the nut another half turn to assure

a better seal.

Install the condensate line (included in drain kit). Insert condensate tubing by pushing clear plastic line over drain adapter. Make condensate trap by

looping the clear plastic tubing. This procedure is to avoid foul odor to enter the FAA.

The drain nipple is placed upside down in the unit to prevent it being damaged during shipping or the installation of the unit.

The Switch on the electrical box is used to toggle between STANDBY, REDUCED speed and NORMAL speed modes.

Place the unit in NORMAL speed to perform the balancing.

Make a loop in condensate line, not be subject to

freezing temperatures.

Use a condensate pump if you don’t have access to a drain.

If outdoor air temperature is above 32°F (0°C) at the extract air (30% RH/72°F, 30% RH /22°C), no drain line installation is required.

If this is the case keep the drain spout as shipped from factory with the cap.

Airflow balancing

Balancing must be completed using the Fantech ECO-Touch®

Programmable Touch Screen Wall Control

ENTERING BALANCING MODE

In the options menu during the initial 5 second countdown

sequence, long press on "ECO" area for 5 seconds to

enter basic balancing mode. The supply and exhaust

fans are adjusted on high speed only and the offsets

are proportionally applied to the medium and low speed

automatically.

SPEED):

• In this step, balance exhaust fan and

measure airow on the exhaust air side

• Pressing on "up" or "down" will adjust the fan

speed in increments of 1%.

• Once the desired exhaust airow is reached,

press on "next" and move on to the next

stage.

STAGE 2

(BALANCE SUPPLY FAN ONLY IN HIGH

SPEED):

• In this step, balance supply fan and measure

airow on the supply air side

• Pressing on "up" or "down" will adjust the fan

speed in increments of 1%.

• Once happy with the outcome, press on

"next" to complete balancing

• The supply and exhaust offset values will be

proportionally applied to low and medium

speed as well.

CONNECTION TO

A COOLING SYSTEM:

On some newer furnaces and older

thermostats, energizing the R and

G terminal at the furnace has the

effect of energizing the Y at the

thermostat and thereby turning on

the cooling system. If you identify this

type of thermostat, you must use the

“Alternate Furnace Interlock Wiring”

Standard Accessory Control Contact

Alternative Accessory Control Contact

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.

TROUBLESHOOTING

Problem Causes Solutions

Air is too dry Dehumidistat control is set too low Increase the desired level of humidity. Change ventilation mode from

continuous mode to standby.

FAA out of balance Have contractor balance FAA airows

Air is too humid Dehumidistat control is set too high Reduce the desired level of humidity. Combine this with the use of continuous

exchange mode.

Sudden change in temperature Wait until outside temperature stabilizes (winter). Heating will also improve

situation.

Storing too much wood for heating Store a majority of your wood outside. Even dried, a cord of wood contains

more than 20 gallons of water.

Dryer vent exhaust is inside home Make sure the dryer vent is exhausting outside.

Poor air circulation near windows Open curtains or blinds.

FAA out of balance Have contractor balance FAA airows

Well sealed basement door is closed Open the door or install a grill on the door.

Failed damper system may be stuck in recirculation

mode

Check defrost damper. If damper is always blocking incoming fresh air, have

contractor verify damper system.

Persistent condensation

on window

Improper adjustment of dehumidistat control Reduce the desired level of humidity. Combine this step with use of continuous

exchange mode.

FAA out of balance Have contractor balance FAA

Poor air circulation near windows Open curtains or blinds.

Poor Air Flows 1/4" (6mm) mesh on the outside hoods is plugged Clean exterior hoods or vents

Filters plugged Remove and clean lter

Core obstructed Remove and clean core

Indoor grilles closed or blocked Check and open grilles

Inadequate power supply at site Have electrician check supply voltage

Ductwork is restricting airow Check duct installation

Improper speed control setting Increase the speed of the FAA (i.e. change unit control from REDUCED to NORMAL

speed)

FAA airow improperly balanced Have contractor balance FAA airows

Ducting has fallen down or been disconnected from FAA Have contractor reconnect ducting

Supply air feels cold Poor location of supply grilles, the airow may irritate

the occupant

Locate the grilles high on the walls or under the baseboards, install ceiling

mounted diffuser or grilles so as not to directly spill the supply air on the

occupant (eg. Over a sofa)

Turn down the FAA supply speed. A small duct heater (1kw) could be used to

temper the supply air

Placement of furniture or closed doors is restricting the movement of air in

the home

Outdoor temperature extremely cold If supply air is ducted into furnace return, the furnace fan may need to run

continuously to distribute ventilation air comfortably

FAA and/or Ducts frosting up FAA air ows are improperly balanced Have HVAC contractor balance the FAA airows

Malfunction of the FAA defrost system Note: minimal frost build-up is expected on the core before unit initiates

defrost cycle functions

Condensation or Ice Build Up in

Insulated Duct to the Outside

Incomplete vapor barrier around insulated duct Tape and seal all joints

A hole or tear in outer duct covering Tape any holes or tears made in the outer duct covering

Ensure that the vapor barrier is completely sealed.

LED is ashing Everything is in good operations

LED is not ashing No Power is being transmitted to the Control Board Make sure unit is plugged.

Transformer may need replacing.

Note: It is best to get the unit checked by a certied HVAC Contractor/Technician.

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 appareil à air frais (AAF) au moyen de la procédure d’équilibrage du présent manuel. Il

importe de toujours évaluer l’interaction du AAF 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%
