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.

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.

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.

2.4 INSTALLATION FOR ERV UNITS ONLY

2.4.1 GEOGRAPHICAL LOCATION

The ERV units are created to meet specific requirements related to geographical locations. Take a look at the map below; the shaded area shows the limits where the ERV unit can be installed. However, there is no geographical limitation for installing an HRV unit.

VN0006

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.

2.4.2 ERV U

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).

NOTE: To get the most of your ERV unit, the ambient temperature around the unit should be conditioned. If the unit has to be installed in

an unconditioned space, the heat gains or losses from the unit and the ducts could increase the operation costs of the unit.

• Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.

NITS ATTIC INSTALLATION

• The attic temperature must always be above 0°C (32°F) and under 65°C (149°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.

CAUTION

VH0058

3. INSTALLATION

J003

3.1 INSPECT THE CONTENTS OF THE BOX

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

• Remove and discard both transport brackets (A) and open the door. Discard the styrofoam

fillers (ERV units only) and remove the hardware kit from the unit. Inspect the interior of the unit for damage. Ensure that heat or energy recovery core, core filters, insulation, dampers, etc. are all intact.

VD0183

3.2 LOCATING THE UNIT Choose an appropriate location for the unit.

• Within an area of the house where the ambient temperature is kept between 18°C (65°F) and 40°C (104°F) (basement, furnace room, closet, etc.)

• So as to provide easy access to the interior of the unit, for 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).

• For HRV units ONLY: Close to a drain. If no drain is close by, use a pail to collect run-off.

3.3 UNIT PREPARATION

Both HRV and ERV units are equipped with 2 ports having integrated balancing damper. Turn the thumb screw (B) clockwise to manually open and adjust the damper (C).

HRV UNITS: Set the Fresh air to building port to wide open position, and adjust the Exhaust air to outside port

to 3rd notch.

NOTE: If the unit needs to be balanced, adjust the damper of the Exhaust air to outside port to wide open

position. See Section 7.

ERV UNITS: Set both Fresh air to building port and Exhaust air to outside port to wide open position.

3.4 HOW TO HANG THE UNIT

Hang the unit with the 4 chains, hooks and springs provided.

CAUTION

Make sure the unit is level.

VD0185

VD0184

If there is not enough space on top of the unit, slightly bend the hooks and install them lower on the unit. See figure at right.

VD0187

3.5 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.

3.6 INSTALLING THE DUCTWORK AND REGISTERS

WARNING

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.

3.6.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.1)

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 in the ceiling OR 6 to 12 inches (152 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.

CAUTION

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

VJ0042

Apply duct tape to the joint making an airtight seal. Avoid compressing the insulation when pulling the tape tightly around the joint. Compressed insulation loses its R value and causes water dripping due to condensation on the exterior surface of the duct.

Rigid ducts:

CAUTION

Do not use screws to connect the rigid ducts to the ports.

Use a small length of flexible duct to connect the rigid duct to the ports in order to avoid vibration transmissions. Use tie-wraps to

perform connections.

3.8 INSTALLING THE TANDEM® TRANSITION* KIT

Use the following procedure for connecting the insulated flexible ducts to the Tandem Transition (Exhaust air to outside and Fresh air from outside).

NOTE: The joist opening needed to install the Tandem

The maximum height of the Tandem® transition is 8¾”. See tandem Transision end view at right. If the joists are perpendicular to the ducts, or if the connection to the exterior hood is in a limited area, your installation will need two exterior hoods instead of one. In this case, do not use the Tandem Transition kit. See next Section

• There must be a minimum distance of 6’ (1.8 m)

between the hoods to avoid cross-contamination

• There must be a minimum distance of 18” (457 mm)

from the ground

WARNING

Make sure the intake hood is at least 6 feet (1.8 m) away (or more, as per applicable building codes or standards) from any of the following:

• Dryer exhaust, high efficiency furnace vent, central vacuum vent

• Gas meter exhaust, gas barbecue-grill

• Any exhaust from a combustion source

• Garbage bin and any other source of contamination

OOT SEQUENCE

The unit boot sequence is similar to a personal 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 or AMBER for 5 seconds, and then will shut off for 2 seconds. After that, the LED will light RED for the rest of the booting sequence. 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.

4.2 ELECTRICAL CONNECTION TO OPTIONAL WALL CONTROLS

For more convenience, this unit 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 illustration at right, wire A is correctly inserted, but not wire B.)
