2. TYPICAL INSTALLATIONS

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.

If required, bathroom fans and a range hood may 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.

2.1 FULLY DUCTED SYSTEM (PRIMARILY 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.

VH0081

2.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM)

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.

2.3 SIMPLIFIED INSTALLATION (CONNECTION TO A FORCED AIR 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.

4. INSTALLATION

4.1 INSPECT THE CONTENT OF THE BOX

Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, ports, power cord, etc.

4.2 LOCATING THE UNIT

Choose an appropriate location for the unit.

• Within an area of the house where the ambient temperature is kept between 10°C (50°F) and 40°C (104 °F).

• Away from living areas (dining room, living room, bedroom), if possible.

• So as to provide easy access to the interior of the unit, for quarterly and annual maintenance.

• Close to an exterior wall, so as to limit the length of the insulated flexible duct to and from the unit.

• Away from hot chimneys and other fire hazards.

• Allow for a power source (standard 3-prong grounding outlet).

• Close to a drain (HRV units only). If no drain is close by, use a pail to collect run-off. Hang the unit with the four chains and springs provided. See illustration beside.

Make sure the unit is level.

4.3 PLANNING OF THE DUCTWORK

• Keep it simple. Plan for a minimum of bends and joints.

• Keep the length of insulated ducts to a minimum.

• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or a range hood. This would cause clogging of the filters and recovery module.

• If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level.

VD0242

CAUTION

4.4 INSTALLING THE DUCTWORK AND REGISTERS

ULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1)

4.4.1 F

Never install a stale air exhaust register in a closed room where a combustion device operates, such as a gas furnace, a gas water heater or a fireplace.

Stale air exhaust ductwork

• 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 to 12 inches (152 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 either in the ceiling or high on the walls with air flow directed towards the ceiling. (The cooler air will then cross the upper part of the room and mix with room air, before descending to occupant’s level.)

• If a register must be floor installed, direct the airflow up the wall.

4.5 CONNECTING THE DUCTS TO THE UNIT

NOTE: All units ports were created to be connected to ducts having a minimum of 4” diameter, but if need be, they can be connected to bigger sized ducts by using an appropriate transition (e.g.: 4” diameter to 5” diameter transition).

Insulated flexible ducts

Use the following procedure to connect the insulated flexible ducts to the ports of the unit (Exhaust air to outside and Fresh air from outside ports).

All units have those 2 ports equipped with integrated balancing damper. Prior to install the insulated flexible ducts, ensure these both ports have their damper entirely open (their adjusment pin (A) must be set vertical, as shown beside).

VJ0033

CAUTION

If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts.

 Pull back the insulation to expose the flexible duct.  Attach the flexible duct to the port using tie wrap.  Pull the insulation over the joint and tuck in between the inner and outer rings of the double collar.  Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Fasten in place the vapor

barrier using the port strap included in unit par ts bag). To do so, insert one collar pin through vapor barrier and first strap hole, then insert the other collar pin through vapor barrier and center strap hole and close the loop by inserting the first collar pin in the last strap hole.

CAUTION

Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within the ducts.

4. INSTALLATION (CONT’D)

4.8 CONNECTING THE DRAIN

CAUTION

A drain tubing (included) must be installed for all HRV units. For ERV units, it is not required, however, it is recommended for climates where the outside temperature typically remains below -25°C (-13°F), (over a 24-hour period) for several days in a row, combined with an indoor humidity of 40% or higher.

Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the drain source. Run the tube to the floor drain or to an alternative

VO0190

Connect the plastic tube to the inner drain fitting located under the unit as shown.

NOTE: For ERV units, remove drain plug outside the unit prior to install tubing.

drain pipe or pail.

IMPORTANT

If using a pail to collect water, locate the tube end approximately 1” from the top of the pail in order to prevent water from being drawn back up into the unit.

5. CONTROLS

All units are equipped with an integrated control located on upper left side of the unit. Plug the unit.

5.1 BOOTING SEQUENCE

The unit booting sequence is similar to a personnal computer boot sequence. Each time the unit is plugged after being unplugged, or after a power failure, the unit will perform a 30-second booting sequence before starting to operate.

During the booting sequence, the integrated control LED will light GREEN for 5 seconds, and then will turn RED. During this RED light phase, the unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the RED light turns off and the booting sequence is done.

NOTE: No command will be taken until the unit is fully booted.

5.2 INTEGRATED CONTROL

Use the push button (1) to control the unit. The LED (2) will then show on which mode the unit is in.

Refer to table below to see how to operate the unit using its integrated control.

PRESS ON PUSH BUTTON LED COLOR RESULTS

ONCE AMBER UNIT IS ON LOW SPEED

TWICE GREEN UNIT IS ON HIGH SPEED

THREE TIMES NO LIGHT UNIT IS OFF

If a problem occurs during the unit operation, its integrated control LED (2) will blink. The color of the blinking light depends on the type of error detected. Refer to Section 9 Troubleshooting on page 21 for further details.

NOTE: WHEN USING MAIN CONTROL, THE INTEGRATED CONTROL MUST BE TURNED OFF.

5. CONTROLS (CONT’D)

5.3 SETTNG EXTENDED DEFROST

These units are factory set to normal defrost. In cold region (outside temperature -27°C [-17°F] and lower), it may be necessary to setup extended defrost. During the first 2 seconds of booting sequence, while the integrated control LED is GREEN, press on push button for 3 seconds to set the unit in extended defrost; the LED will blink AMBER to show the unit is in extended defrost mode. After that, the LED will shut off, then light RED (the unit returns in its booting sequence).

5.4 ELECTRICAL CONNECTION TO MAIN CONTROLS

For more convenience, these units can also be controlled using an optional main wall control. NOTES: 1. The integrated control must be turned OFF to use an optional main control.

2. If an optional auxiliary control is used, if activated, this auxiliary control will override the optional main control.

WARNING

Always disconnect the unit before making any connections. Failure in disconnecting power could result in electric 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. On picture beside, wire A is correctly inserted, but wire B is not.)

6. ELECTRICAL CONNECTION TO THE FURNACE

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.

8. BALANCING THE UNIT

8.1 WHAT YOU NEED TO BALANCE THE UNIT

• A magnehelic gauge capable of measuring 0 to 0.5 inch of water (0 to 125 Pa) and 2 plastic tubes.

• The balancing chart of the unit, located on the unit door.

8.2 PRELIMINARY STAGES TO BALANCE THE UNIT

• Seal all the unit ductwork with tape. Close all windows and doors.

• Turn off all exhaust devices such as range hood, dryer and bathroom fans.

• Make sure the balancing dampers are fully open (their adjusment pin (A) must be set vertical, see illustration beside).

• Make sure all filters are clean (if it is not the first time the unit is balanced).

VP0009

8.3 BALANCING PROCEDURE

1. Set the unit to high speed. NOTE: 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 on unit

door). Be sure to connect the tubes to their appropriate high/low fittings. If the gauge drops below zero, reverse the tubing connections.

4. Note the CFM value from balancing chart on unit.

5. Repeat steps 3 and 4, but to FRESH air flow pressure taps.

6. Match highest CFM value to lowest by adjusting the balancing damper corresponding

to the highest value. To do so, rotate the adjusment pin.

See example below:

PRESSURE FRESH EXHAUST

. W.G. CFM CFM

0.16 47 42

0.18 54 48

0.2 60 55

0.22 66 61

0.24 72 68

0.26 78 74

0.28 84 81

0.3 90 88

In that case, there is 78 CFM in FRESH air and 61 CFM in EXHAUST air. Then, using the adjusment pin, adjust (close) the FRESH air balancing damper until the FRESH air flow matchs the EXHAUST air flow: 60 CFM (0.2 in. w.g.) with magnehelic gauge connected to FRESH air flow pressure taps).

7. Secure both dampers in place with a fastening screw (included in the hardware kit).

8. 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).

NOTES: 1. Use conversion chart provided with the unit to convert magnehelic gauge readings to equivalent cfm values.

2. 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.
