2. TYPICAL INSTALLATIONS
Installations may vary according to the type of unit and the ports configuration (top or sides). Use the following illustrations as guidelines to help you decide on how the unit will be installed.
All the units should be hung from the joists.
In every case, bathroom fans and a range hood should be used to exhaust stale air. Also, for homes with more than one level, we recommend one exhaust register at the highest level.
There are 3 installation methods: Fully ducted, Central Draw Point and Simplified Installation.
NOTE: An electrical outlet has to be available within 3 feet of the unit.

RIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING
)
Stale air coming from the registers located at the highest level of the house is exhausted to the outside. Fresh air from outside is filtered and supplied by the register located in the lowest liveable level.
Homes with more than one level require at least one exhaust register at the highest level.
See figure at right.

Stale air coming from the registers located at the highest level of the house is exhausted to the outside. Fresh air from outside is filtered and supplied to the return (plenum) or the supply duct of the forced air unit. See figure at right.
For this type of installation, it is not essential that the forced air system blower runs when the unit is in operation, but we recommend it.
NOTE: Home with multiple forced air systems should have one unit on each system.

Stale air is exhausted to the outside. Fresh air from outside is filtered and supplied to the return (plenum) or the supply duct of the forced air unit. See figure at right.
To avoid cross-contamination and achieve the highest efficiencies, the forced air system blower must always be ON.
NOTE: Home with multiple forced air systems should have one unit on each system.

NOTE: The ERV unit is designed to assist in the management of humidity introduced into the home.
During cooling season, in extreme humidity conditions, the use of additional dehumidification unit may be required to quickly remove all excess moisture. During heating season, in extreme dryness conditions, the use of a humidifier may be required if the indoor air is still too dry.

NSTALLATION
All 3 types of installations can be used in the attic (Fully ducted system, Central Draw Point or Simplified). The example shown below is a Simplified installation (connection to a forced air system).
CAUTION
Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.
CAUTION
The attic temperature must always be above 0°C (32°F).
Stale air is exhausted to the outside. Fresh air from outside is filtered and supplied to the return (plenum) of the forced air unit.
See figure at right.
To avoid cross-contamination and achieve the highest efficiencies, the forced air system blower must always be ON.
NOTE: Home with multiple forced air systems should have 1 unit on each system.

• Install the stale air exhaust registers where the contaminants are produced: kitchen, living room, etc. Position the registers as far from the stairway as possible and in such a way that the air circulates in all the lived-in spaces in the house.
• If a register is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.
• Install the registers 6 in. to 12 in. (152 mm to 305 mm) from the ceiling on an interior wall OR install them in the ceiling.
Fresh air distribution ductwork
• Install the fresh air distribution registers in bedrooms, dining rooms, living room and basement.
• Keep in mind that the fresh air registers must be located as far as possible from the stale air registers.
• Install the registers in the ceiling or 6 in. to 12 in. (152 mm to 305 mm) from the ceiling on an interior wall. The duct length should be at least 15’ (4.6 m). (The fresh air will then flow through the room and mix with room air, ensuring a continuous renewed airflow.)
• If a register must be floor installed, direct the airflow up the wall.

WARNING
When performing duct connections, always use approved tools and materials. Respect all corresponding laws and safety regulations. Please refer to your local building code.
CAUTION
When performing duct connections to the furnace supply duct, this duct must be sized to support the additional airflow produced by the HRV/ERV. Also, use a steel duct. It is recommended that the HRV/ERV is running when the furnace is in operation to prevent backdrafting inside HRV/ERV.
There are 2 methods for connecting the unit to the furnace/air handler:
Method 1: Supply side connection
• Cut an opening into the furnace supply duct at least 18 inches (0.5 m) from the furnace/air handler.
• Connect this opening to the Fresh air to building port of the HRV/ERV (use steel duct, see figure beside).
• Make sure the HRV/ERV duct form an elbow inside the furnace/air handler ductwork.

WARNING
Always disconnect the unit before making any connections. Failure in disconnecting power could result in electrical shock or damage of the wall control or electronic module inside the unit.
CAUTION
Never install more than one optional main wall control per unit. Make sure that the wires do not short-circuit between themselves or by touching any other components on the wall control. Avoid poor wiring connections. To reduce electrical interference (noise) potential, do not run wall control wiring next to control contactors or near light dimming circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.
Use the terminal connector included in the installation kit to perform the electrical connection for main and optional wall controls. Check if all wires are correctly inserted in their corresponding holes in the terminal block. (A wire is correctly inserted when its orange receptacle is lower than another one without wire.

!
WARNING
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low voltage class 2 circuit of the furnace blower control.
For a furnace connected to a cooling system:
On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “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.

To avoid balancing, the difference between stale air ducts total length and fresh air ducts total length must not exceed 50 ft. However, even if the stale air ducts and fresh air ducts lengths are almost equal, your local building codes may require balancing the unit.
If the unit does not need to be balanced, shut all the pressure taps (located on the unit door) with the small plastic plugs included in the hardware kit.

1.
Set the unit to high speed.
Make sure that the furnace/air handler blower is ON if the installation is in any way connected to the ductwork of the cold air return. If not, leave furnace/air handler blower
OFF. If the outside temperature is below 0°C / 32°F, make sure the unit is not running in defrost while balancing. (By waiting 10 minutes after plugging the unit in, you are assured that the unit is not in a defrost cycle.).
2.
Place the magnehelic gauge on a level surface and adjust it to zero.
3.
Connect tubing from gauge to EXHAUST air flow pressure taps (see diagram beside).
Be sure to connect the tubes to their appropriate high/low fittings. If the gauge drops below zero, reverse the tubing connections.

Place the magnehelic gauge upright and level. Record equivalent AIR FLOW of the reading according to the balancing chart.
4.
Move tubing to FRESH air flow pressure taps (see diagram). Adjust the fresh air balancing damper until the fresh air flow is approximately the same as the EXHAUST air flow. If fresh air flow is less than exhaust air flow, then go back and adjust the exhaust balancing damper to equal the fresh air flow.
5.
Secure both dampers thumb screw in place with tape.
6.
Write the required air flow information on a label and stick it near the unit for future reference (date, maximum speed air flows, your name, phone number and business address).
NOTE: The unit is considered balanced even if there is a difference of ±10 cfm (or ± 5 l/s or 17 m³/h) between the two air flows.

VO009 3
Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the drain source. Make sure this loop is situated BELOW the “T” as shown. This will prevent water from being drawn back up into the unit in case of negative pressure. Run the tube to the floor drain or to an alternative drain pipe or pail. Be sure there is a slight slope for the run-off.

11. TROUBLESHOOTING
If the integrated control LED of the unit is flashing, this means the unit sensors detected a problem. See the table below to know where on the unit the problem occurs.
LED flashes GREEN.
LED flashes AMBER.
LED flashes RED.
• Thermistor error.
• Damper error.
• The door is open and the unit is not unplugged.
• Exhaust motor error.
Replace the entire port assembly (fresh air from outside port).
Go to Point 6.
Close the door and press once on the integrated control push button to reset the unit.
Go to Point 5.
Problems
1. Unit does not work.
2. The damper actuator does not work.
3. The wall control does not work OR the indicators flash.
4. The Humidity Control does not work OR the
20-minute push-button timer does not work OR its indicator light does not stay on.
5. The supply and/or exhaust motor do not work.
6. The defrost cycle does not work (the fresh air duct is frozen OR the fresh air distributed is very cold.
7. The integrated control push button does not work.
Possible causes
• The circuit board may be defective.
• The damper actuator or the integrated damper port mechanism may be defective.
You should try this
• Unplug the unit. Disconnect the main control and the auxiliary control(s) (if need be).
Jump G and B terminals. Plug the unit
NO C NC I OC OL Y R G B back and wait about 10 seconds. If the motors run on high speed and the
VE0097 damper opens, the circuit board is not defective.
• Unplug the unit. Disconnect the main control and the optional control(s) (if need be). Wait 10 seconds and plug the unit back. Check if the damper opens. If not, use a multimeter and check for 24V AC on J12-1 and J12-2
(in electrical compartment). If there is 24V AC, replace the entire port assembly.
NOTE: It is normal to experience a small delay (7-8 seconds) before detecting the 24V AC signal at starting-up. This signal will stay during 17-18 seconds before disappearing.
• If there is no 24V AC, replace the circuit board.
• The circuit board may be defective.
• The wires may be in reverse position.
• The wires may be broken.
• The wire in the wall OR the wall control may be defective.
• The wires may be in reverse position.
• The Humidity Control or push button may be defective.
• The circuit board may be defective.
• The motor(s) may be defective.
• Ensure that the color coded wires have been connected to their appropriate places.
• Inspect every wire and replace any that are damaged.
• Remove the wall control and test it right beside the unit using another shorter wire. If the wall control works there, change the wire. If it does not, change the wall control.
• Ensure that the color coded wires have been connected to their appropriate places.
• Jump the OL and OC terminals. If the unit switches to high speed, remove the
Humidity Control or push button and test it right beside the unit using another shorter
NO C NC I OC OL Y R G B wire. If it works here, change the wire. If it
VE009 8 doesn’t, change the Humidity Control or the push button.
• Press on the integrated control push button until the unit turn on low speed
(the LED will light AMBER). Using a multimeter, check the voltage on J4-1 and J4-2 (for supply motor), and on J5-1 and J5-2 (for exhaust motor). The reading must be ± 68 V AC. Then set the unit on high speed by pressing on the integrated control 1 more time (the LED will light GREEN). Using a multimeter, check the voltage on J4-1 and J4-2 (for supply motor), and on
J5-1 and J5-2 (for exhaust motor). The reading must be ± 120 V AC if the fan motor speed setting is Low-High, or ± 90 V AC if the fan motor speed setting is Low-Medium. If all the readings correspond to the right voltage values, the circuit board is not defective. If one or both readings are different, change the circuit board.
• Using a multimeter, check the ohms value on each motor connectors. For
BLUE and BLACK motor wires, the right value is ± 52 ohms. For BLUE and
BROWN motor wires, the right value is ± 72 ohms. For BROWN and BLACK motor wires, the right value is ± 124 ohms. If the ohm values are the same, the motor is not defective. Replace the motor capacitor.
• Ice deposits may be hindering the damper operation.
• The damper rod or the port damper itself may be broken.
• The damper actuator or circuit board may be defective.
• Remove the ice.
• Inspect these parts and replace if necessary.
• See point 2.
• The 30-second boot sequence is not completed.
• See Section 4.1.1 Boot Sequence.
