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

Hang the unit with the four hooks, chains and springs provided. See illustration at right.
CAUTION
Make sure the unit is level.

3.4 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.

3.5 INSTALLING NON-INSULATED DUCTS AND DIFFUSERS
3.5.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 1.1)

WARNING
Never install a stale air exhaust diffuser 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 diffuser in the main area where the contaminants are produced: kitchen, living room, etc. Position the diffuser 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 desired, you can install another diffuser (sold separately).

• If a diffuser is installed in the kitchen, it must be located at least 4 feet (1.2 m) from the range.

• Install the diffuser 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install it in the ceiling.
  Fresh air distribution ductwork

• Install the fresh air distribution diffuser in a large, open area in the lowest level to ensure the greatest possible air circulation.

• Keep in mind that the fresh air diffuser must be located as far as possible from the stale air diffuser. If desired, you can install another diffuser (sold separately).

• Install the diffuser either in the ceiling OR 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall. (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.

HOW TO CONNECT THE FLEXIBLE DUCTS TO THE DIFFUSERS

Once the diffusers location is determined, cut out 5¼” diameter hole.
Run one end of the flexible duct through the hole and fix it to the diffuser base (1), using a tie wrap and duct tape. Assemble the diffuser base to the wall (or ceiling using its 4 no. 8 x 3/4” screws. Then, slide in the diffuser (2).
See illustration at right.

UNIT PORTS IDENTIFICATION
Each unit port has an identification label beside it to avoid wrong duct connections to the unit. Always refer to these labels before performing any duct and port connection.

3.5 INSTALLING NON-INSULATED DUCTS AND DIFFUSERS (CONT’D)
3.5.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 1.1) (CONT’D)

HOW TO CONNECT THE FLEXIBLE DUCTS TO THE UNIT PORTS
Both flexible ducts attached to the diffusers must be connected to the bottom ports of the unit. When facing the unit door, the fresh air to building port is located on left side
and the exhaust air from building port is on the right side. Refer to the identification labels affixed beside each unit ports. Using tie wrap, attach the fresh air to building duct to its corresponding port, then do the same for the exhaust air to building duct and port. See illustration at right.
NOTE: Use an insulated duct (not included) if the duct will have to go through a space where it is possible to experience extreme temperature conditions (eg: in northern area, not unheated attic in winter or uncooled attic in southern area). Also, if you plan to stop the unit for more than 12 hours, we recommend to cover the duct with R12 insulation.

3.5.2 CENTRAL DRAW POINT (AS ILLUSTRATED IN SECTION 1.2)

3.6 INSTALLING INSULATED FLEXIBLE DUCTS

CAUTION
Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within the ducts.
Use the following procedure for connecting the insulated flexible ducts to the Tandem® transition (exhaust air to outside and fresh air from outside).
NOTE: If the joists are perpendicular to the ducts, or if the connection to the exterior hood is in a limited area, the installation will need two exterior hoods instead of one. In this case, do not use the Tandem transition; go to point 3.6.2 and refer to the optional single hood enclosed instructions.

3.6.1 CONNECTION TO TANDEM TRANSITION

1. For each duct, pull back the insulation to expose the interior flexible duct.
2. Connect the interior flexible duct to the smaller part of the Tandem transition (5’’ oval) using a tie wrap.
3. Pull the insulation over the joint. Pull the vapor barrier over the insulation.
4. Apply duct tape gently to the joint in order to make an airtight seal. See figures below.

CAUTION
The exhaust air to outside duct MUST BE connected to the TOP of Tandem transition.

3.6 INSTALLING INSULATED FLEXIBLE DUCTS (CONT’D)
3.6.2 CONNECTION TO THE UNIT PORTS
Use the following procedure for connecting the insulated flexible ducts to the unit ports (exhaust air to outside and fresh air from outside). Refer to identification labels beside ports before performing any duct and port connection.

1. For both remaining ducts, pull back the insulation to expose the interior flexible duct.
2. Connect the interior flexible duct to the inner ring of the port using a tie wrap.
3. Pull the insulation over the joint and tuck it between the inner and outer rings of the port. Pull the vapor barrier over the insulation and over the outer ring of the port.
4. Apply duct tape carefully to the joint in order to make an airtight seal. See figures below.

CAUTION
Avoid compressing the insulation when you pull the tape tightly around the joint. Compressed insulation loses its insulation properties and causes water dripping due to condensation on the exterior surface of the duct.

3.8 CONNECTING THE SRAIN
Cut two sections of plastic tubing, approximately 12” long, and connect each one to both inner drain fittings located under the unit as shown.
Join these both sections to the “T” junction and main tube as shown, to prevent the unit from drawing unpleasant odors from the drain source.

Run the tube to the floor drain or to an alternative 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.

CONTROLS

This unit is equipped with an integrated defrost control located under the electrical compartment of the unit. Plug the unit.
4.1 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 booting sequence before starting to operate.
During the booting sequence, the integrated defrost control LED (2 in illustration below) will be OFF for 3 seconds, and then will turn RED for the rest of the booting sequence (approximately 15 seconds). During this RED light phase, the unit is checking and resetting the motorized damper position. Once the motorized damper position completely set, the booting sequence is done; the color of the LED will show on which defrost cycle the unit is set.
NOTE: No command will be taken until the unit is fully booted.
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 7 Troubleshooting on last page for further details.

4.2 DEFROST CYCLES
Five seconds after the booting sequence is done, the LED (2) will light and stay lit to show in which defrost cycle the unit is set. Use the push button (1) to change the defrost cycle of the unit (see tab below).

NOTE: There is a 15-minute delay for the new defrost cycle choice to be kept in memory; if a power failure occurs during this time delay, when the power returns, the unit resume to its previous setting.

According to your need, there are 3 defrost cycles available:
STANDARD: This is the factory set defrost cycle, which is the most commonly used to suit normal weather conditions. When needed, the unit will perform defrost cycle on high speed.
PLUS: This mode has been created for people who live in cold region (outside temperature -27°C [-17°F] and lower). This setting makes the unit perform defrost cycle on high speed for a longer period of time.
DISCRETION: When needed, the defrost cycle will be performed on the same speed than the unit ventilation speed. For example, if the unit is set on high speed, the defrost cycle will be done on high speed, but if the unit is set on low speed, the defrost cycle will be done on low speed.

4.3 MAIN WALL CONTROL INSTALLATION
These units should be controlled using a main wall control (included).
NOTE: If an optional auxiliary control is used, if activated, this auxiliary control will override the main control operation.

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
Failure to comply with the following can cause erratic operation of the unit and/or the wall control:

• Never install more than one main wall control per ventilation unit;
• Keep control low voltage wiring at least 1 foot (305 mm) away from motors, lighting ballast, light dimming circuit and power distribution panel. Do not route control wiring alongside house power wiring;
• Ensure the wires are securely connected.

1. Route the control cable (included) from the unit to a convenient location for the wall control.
2. Loosen the locking screw (the screw should not be removed).
3. Detach the faceplate from the mounting plate by pulling the bottom part. If necessary, bore the mounting holes and insert anchors.
4. Run the cable (4 wires) through the opening of the mounting plate and mount the plate to the wall using 2 screws (included in the unit parts bag).
5. Splice back the end of the cable to access the 4 wires. Strip the end of each wire. Connect each wire to its corresponding terminal: YELLOW wire to “Y’’, RED wire to “R’’, GREEN wire to “G’’ and BLACK wire to “B’’. See illustration at right.
6. Reinstall the front module onto the back plate and tighten the locking screw.

4.4 WALL CONTROL (S) CONNECTION TO THE UNIT
Use the terminal connector included in the installation kit to perform the electrical connectionfor 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.) Splice back the end of the cable to access the 4 wires. Strip the end of each wire. Connect each wire to its corresponding terminal: YELLOW wire to “Y’’, RED wire to “R’’, GREEN wire to “G’’ and BLACK wire to “B’’. Check if all wires are correctly inserted in their correspondingholes in the terminal block.
