USING THIS UNIT

CAUTION

Before using this unit for the first time, please take the time to carefully read page 2 of this guide to ensure it is used safely and and properly

Your ventilation system

This unit is designed to provide fresh air to your home while exhausting stale, humid air. By eliminating accumulated pollutants and humidity, it maintains an optimum air quality and an ideal relative humidity. It is equipped with a recovery core that is designed specifically to control excess humidity and reduce ventilation costs by recovering the heat or energy from the exhausted air, and using that same heat or energy to warm the fresh air being supplied. This recovery process is accomplished in such a way that the stale air is never mixed with the fresh air.

When the outdoor temperature is below -5°C (23°F), recovery creates frost in the module. To maintain proper operation, the unit is programmed to defrost the recovery module. The defrost duration and frequency vary according to the outdoor temperature. After defrosting, the unit returns to the operating mode selected by the user

Integrated Control

Unit Booting Sequence
The unit’s booting sequence is similar to a personnal computer’s booting sequence. Each time the unit is plugged in after being unplugged, or after a power failure, it will perform a 30-second booting sequence before starting to operate. No command will be taken until the unit is fully booted.

This unit is equipped with an integrated control, located on its upper left side.

• Use the integrated push-button (1) to go from OFF to Low Speed, to High Speed, and back to OFF.
• The color of the LED indicator shows what speed the unit is running in:
  LED COLOR| R ESULTS
  ---|---
  AMBER| Unit is on Low speed
  GREEN| Unit is on High speed
  NO LIGHT| Unit is OFF or controlled by a main control
• If a problem occurs while the unit is running, the LED indicator (2) will blink. The color of the blinking light indicates the type of error detected. Refer to Troubleshooting section.

For more convenience, these units can also be controlled using an optional wall control. When using an optional control, unit must be set to OFF using the integrated push-button.

• Exhaust hood
• 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

*Installing Dual Exterior Hood Using Tandem® Transition Kit (optional)**

If desired, a dual exterior hood can be used instead of 2 exterior hoods to connect inulated ducts. The joist opening needed to install the Tandem® transition is 9¾” minimum. The maximum height of the Tandem® transition is 8¾”.

To connect 4” insulated flexible ducts to the 5” oval ends of the Tandem® transition (Exhaust air to outside and Fresh air from outside), connect an adapter to the Tandem® transition (not included) as follows.

For each duct connection:

1. Slightly squeeze a section of 4” round metal duct, at least 8” long, to insert it into the oval opening of the Tandem® transition and push it all the way in.

2. Using silicon, seal the joint between the outside of the metal duct and Tandem® transition, and allow silicon to dry completely.
   CAUTION
   When connecting insulated flexible duct to the Tandem® transition, pull the interior flexible duct over the adapter all the way to the silicon joint and secure using a tie wrap. Then pull the insulation over the joint, making sure that no part is left without insulation.

3. From this point on, follow the instructions included with the Tandem® transition kit (part no. 14690). *Patented.

Connecting the Ducts to the Unit

NOTE: This unit was designed to be connected to ducts of at least 4” in diameter, but can be connected to bigger sized ducts by using an appropriate transition (e.g.: 4” diameter to 5” diameter transition).

CAUTION

Make sure the vapor barrier on the insulated ducts does not tear during installation to avoid condensation within the ducts. If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts.

1. Pull back the insulation to expose the flexible duct.

2. Attach the flexible duct to the port using a tie wrap.

3. Pull the insulation over the joint and tuck it in between the inner and outer rings of the double collar.

4. Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Apply duct tape to the joint to make an airtight seal. Avoid compressing the insulation when pulling the tape tightly around the joint.

Non-insulated rigid ducts
Use metal screws and duct tape to connect the rigid ducts to the unit ports.

Non-insulated flexible ducts
Use tie wraps to connect the flexible ducts to the unit ports.

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.

1. Connect the plastic tube to the drain fitting located under the unit.
   

2. 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 drain pipe or pail.
   

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

CONTROLS

Electrical connection to optional controls

⚠ 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 there are no short-circuit between the wires or with 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 pan

• Use the terminal connector included in the installation kit to perform the electrical connection for main and optional wall controls.
• Make sure 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.

Setting 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 the 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, and turn RED (the unit resumes its booting sequence).

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.

BALANCING THE UNIT

Preparation

Follow these steps to ensure accurate measurements:

• Seal all the 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 vertical, see illustration aside).
• Make sure all filters are clean (if it is not the first time the unit is balanced).
• If the installation is in any way connected to the ductwork of the cold air return of a furnace/air handler, make sure that the furnace/air handler blower is ON. 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.
• Set the unit to high speed.

Balancing Procedure

1. Place the magnehelic gauge on a level surface and adjust it to zero.
2. Connect tubing from gauge to EXHAUST air flow pressure taps (refer to label on unit for gauge connection).
3. 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. Using the appropriate adjustable balancing damper, lower the highest value so it matches the lowest value. A difference up to ±10 cfm is acceptable.
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).
