3.1 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.

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 50°F and 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 regular and

annual maintenance. NOTE: There must be a 27” clearance in front of the unit to fully open

the door. In limited space, the door can be removed by lifting it up, but there must be a 18” clearance in front of the unit to remove the core.

• 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. If no drain is close by, use a pail to collect run-off.

The unit can be hung using provided 4 chains and springs (see at right) or hung to the wall using provided brackets (see next page).

CAUTION

In every case, make sure the unit is level.

3. INSTALLATION (CONT’D)

3.3 PLANNING OF THE DUCTWORK

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

• Keep the length of insulated and non-insulated ducts to a minimum, because the length of the ductwork impacts directly the unit

airflow performances.

• 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.

3.4 DUCT SIZE

To determine the appropriate duct size to be used, refer to the ASHRAE or HRAI HANDBOOK. Below is an example of a design

for a fully ducted system with a unit having a high speed performance of 160 cfm.

3.5 INSTALLING THE DUCTWORK AND REGISTERS

3.5.1 FULLY DUCTED SYSTEM

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.

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 from the range.

• Install the registers 6 to 12 inches from the ceiling on an interior wall OR install them in the ceiling.

• If possible, measure the velocity of the air flowing through the registers. If the velocity is higher than 400 ft/min, then the register

type is too small. Replace with a larger one.

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.

3. INSTALLATION (CONT’D)

3.6 CONNECTING THE DUCTS TO THE UNIT

NOTE: All unit ports are were created to be connected to ducts having a minimum of 6” diameter, but if need be, they can be connected

to bigger sized ducts by using an appropriate transition (e.g.: 6” diameter to 7” diameter transition).

Insulated flexible ducts Use the following procedure to connect the insulated flexible ducts to the ports of the unit (Exhaust air to outdoors and Fresh air

from outdoors ports).

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 parts 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. CONTROLS

4.1 UNIT 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 unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the booting sequence is done.

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

4.2 WALL CONTROL(S) ELECTRICAL CONNECTION

WARNING

The VT9W wall control is the only main wall control compatible to your unit. Never attempt to install another wall control model. Always disconnect the unit before making any connections. Failure to disconnect power could result in electric shock or damage to the wall control or electronic module inside the unit.

CAUTION

Failure to comply with the following can cause erratic operation of the unit and/or the wall control: Never install more than one VT9W 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.

Unplug the unit from power source. Open the side panel to access terminal blocks (A is the one for main control connection only and B is the one for auxiliary controls). Pull out from the unit board the needed connector(s).
