Bathroom: If the ERV 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
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 ERV's airflow must be balanced after installation using the procedure found in the section "AIRFLOW BALANCING"

5
Suggested installation for: � Hydronic baseboard � Infloor heating � Electric baseboard � Mini split heat pump
Benefits: Provides the best fresh air distribution in the house; lowest operation cost since the furnace/air handler unit is not needed.

INSTALLATION EXAMPLES (CONT'D)
DIRECT CONNECTION of the FRESH air to living area to the RETURN PLENUM of the AIR HANDLER (Stale air drawn from key areas of home)
PARTIALLY DEDICATED SYSTEM (BETTER)
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 ERV. See furnace electrical connection on page 15.
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 ERV and the equipment
it is being connected to the ERV'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"

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.
Benefits: Conditions the fresh air prior to distributing it throughout the house

* Unit air flow should be balanced while ERV is on "Normal" speed and furnace blower is running.

Fantech energy recovery ventilators (ERV) that use a supply fan shutdown for frost prevention do not include an outdoor air motorized damper. If you are using a simplified installation, i.e. connecting the ERV supply air duct to a furnace's return air duct, the ERV must operate continuously. When the ERV is turned off, no warm exhaust air will flow through the ERV 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 ERV is installed such that the homeowner may turn off the ERV during the winter, we recommend installing a motorized damper between the ERV's supply air and the furnace's return air duct that closes when the ERV is not operating. See wiring diagram (figure 1). You may also choose to use a Fantech ERV that uses a recirculation defrost that incorporates an outdoor air damper.

Benefits: Least expensive installation type

1. Furnace blower must operate when ventilation from ERV is required. The furnace should be set to run continuously or interlocked with ERV. See furnace electrical connection on page 15.
2. A minimum separation of 1m (39'') is recommended between the two direct connections.
3. In order to prevent exhausting any fresh air, the ERV's exhaust air connection should be upstream of the ERV's supply air connection when ducting to the furnace's cold air return.
4. Due to the difference in pressure between the ERV and the equipment it is being connected to the ERV's airflow must be balanced on site, using the procedure found in the section "AIRFLOW BALANCING"

EXTERIOR DUCTING INSTALLATION

WEATHERHOOD LOCATION
� Decide where your intake and exhaust hoods will be located.

OUTSIDE CORNER 36" (1m)

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.

INTAKE 18" (460mm)

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 ERV 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 ERV. 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 ERV using tape and/or caulking. A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the ERV 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 ERV 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.

STEPS FOR HOOD INSTALLATION:

INSIDE CORNER 36" (1m)

3' (900mm) min.

EXHAUST 18" (460mm)

REQUIRES A WEATHERHOOD WITH A BACKDRAFT DAMPER ON THE EXHAUST SIDE.

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.

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.

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.

4 Using a caulking gun, seal around both hoods to prevent any leaks.

9
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. � 45� elbows are preferable to 90�. � 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 ERV 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 ERV and the supply/exhaust ductwork system. � The main supply and return line to/from the ERV 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 ERV
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 ERV 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 ERV with "dedicated lines".
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
ERV INSTALLATION

� 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

LOCATION
The ERV must be located in a conditioned space where it will be possible to conveniently service the unit. Typically the ERV 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 ERV 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 ERV, damaging the unit.

Connecting any of these types of appliances to the ERV will void your warranty.

Mounting- Chain mount

1 Place fastening hooks on the strapping board or the floor 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.

3 Hang the unit by slipping a link onto the hanging hooks, making sure the unit is level.

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.

11
INSTALLING DRAIN LINE
Through normal operation and during its defrost mode, the ERV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. The ERV 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.
The drain nipple is placed upside down in the unit to prevent it being damaged during shipping or the installation of the unit. For both drain and drainless installation the drain nipple needs to be flipped.

1 Remove the nutsert.

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.

Caution:
A Drain and Tubing (included) must be installed for all HRV units. For ERV units, drain is not required, however, it is recommended for climates where outdoor temperature typically remains below -25�C (-13�F) combined with an indoor relative humidity higher than 40% for a period of 24 hours or several days in a row.

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, ERV unit should be re-balanced after a major renovation or after the installation of extra grilles or registers.

12
Airflow balancing (Cont'd)
Adjusting airflows
A damper is integrated into the Fresh Air to Building collar and on to the Stale Air to Outside. This damper replaces the installation of a separate damper into the Fresh Air to Building and on to the Stale Air to Outside 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 TO THE MECHANISM
Measuring the airflow using station (grid) method

1 Cut 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.

2 Before 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.

3 Adjust the "Supply Air Out" damper until you reach the desired velocity. Follow steps 1-3 to adjust the "Exhaust Air Out" damper, if needed.

Minimum 457mm (18")
Measure here

Measure here
Minimum 457mm (18")

� 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.

Increase the desired level of humidity. Change ventilation mode from continuous mode to standby. Have contractor balance ERV airflows
Reduce the desired level of humidity. Combine this with the use of continuous exchange mode. Wait until outside temperature stabilizes (winter). Heating will also improve situation. Store a majority of your wood outside. Even dried, a cord of wood contains more than 20 gallons of water. Make sure the dryer vent is exhausting outside.
Open curtains or blinds. Have contractor balance ERV airflows
Open the door or install a grill on the door.
Check defrost damper. If damper is always blocking incoming fresh air, have contractor verify damper system.
Reduce the desired level of humidity. Combine this step with use of continuous exchange mode. Have contractor balance ERV
Open curtains or blinds.
Clean exterior hoods or vents
Remove and clean filter
Remove and clean core
Check and open grilles
Have electrician check supply voltage
Check duct installation
Increase the speed of the ERV (i.e. change unit control from REDUCED to NORMAL speed)
Have contractor balance ERV airflows
Have contractor reconnect ducting
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 ERV 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 If supply air is ducted into furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably
