2. TYPICAL INSTALLATIONS There are three common installation methods. 2.1 FULLY DUCTED SYSTEM (Primarily for homes with radiant hot water or electric baseboard heating. See illustration at right.) Moist, stale air is exhausted from the high humidity areas in the home, such as bathrooms, kitchen and laundry room. Fresh air is supplied to bedrooms and principal living areas. If required, bathroom fans and a range hood may be used to better exhaust stale air.
3. INSTALLATION ! WARNING When applicable local regulation comprises more restrictive installation and/or certification requirements, the aforementioned requirements prevail on those of this document and the installer agrees to conform to these at his own expenses. ! WARNING When performing installation, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves. 3.1 INSPECT THE CONTENT OF THE BOX • Inspect the exterior of the unit for shipping damage.
3. INSTALLATION (CONT’D) 3.4 CALCULATING THE DUCT SIZE Use the table below to ensure that the ducts you intend to install will be carrying air flows at or under the recommended values. Avoid installing ducts that will have to carry air flows near the maximum values and never install a duct if its air flow exceeds the maximum value.
3. INSTALLATION (CONT’D) 3.5 INSTALLING THE DUCTWORK AND THE REGISTERS ! WARNING Never install a stale air exhaust register in a room where there is a combustion device, such as a gas furnace, a gas water heater or a fireplace. CAUTION The ductwork is intended to be installed in compliance with all local and national codes that are applicable. 3.5.1 FULLY DUCTED SYSTEM (AS ILLUSTRATED IN SECTION 2.
3. INSTALLATION (CONT’D) 3.5 INSTALLING THE DUCTWORK AND THE REGISTERS (CONT’D) 3.5.3 SIMPLIFIED INSTALLATION (AS ILLUSTRATED IN SECTION 2.3) ! WARNING When performing duct connection to the furnace, installation must be done in accordance with all applicable codes and standards. Please refer to your local building code. CAUTION When performing duct connection to the furnace ducts (Method 1), these ducts must be sized to support the additional airflow produced by the ERV/HRV.
3. INSTALLATION (CONT’D) 3.6 CONNECTING THE DUCTS TO THE UNIT CAUTION If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts. INSULATED FLEXIBLE DUCTS Use the following procedure for connecting the insulated flexible duct to the ports on the unit (exhaust to outside and fresh air from outside). Pull back the insulation to expose the flexible duct and place it over inner port ring.

3. INSTALLATION (CONT’D) 3.8 CONNECTING THE DRAIN (CONT’D) 3.8.2 ERV UNIT 8" MIN. 8" MAX. VD0287 ± 1" Insert a drain plug (included in parts bag) in alternate drain fitting located on top of the unit. VO0243A 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.
4. CONTROLS (CONT’D) 4.2 ELECTRICAL CONNECTION TO OPTIONAL WALL CONTROL For more convenience, this unit can also be controlled using an optional main wall control. ! 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.

9. TROUBLESHOOTING If the integrated control LED of the unit is flashing, this means the unit sensors detected a problem. See the list below to know where on the unit the problem occurs. LED flashes GREEN (double blink). LED flashes AMBER. • Thermistor error. • Damper error. Replace the thermistor kit. Go to point 8. ! WARNING A few diagnosis procedures may require the unit to be in operation while proceeding. Open the unit door and bypass its magnetic switch by putting the door white magnet on it.
9. TROUBLESHOOTING (CONT’D) PROBLEMS POSSIBLE CAUSES 7. The motor does not work. • The circuit board may be defective. • • • • • • • Press on the integrated control push button until the unit turns on low speed (the LED will light AMBER). Using a multimeter, check the voltage on J9-4 and J9-3. Refer to Section 6 Wiring Diagram. The reading must be 120 VAC Then set the unit on high speed by pressing on the integrated control push button one more time (the LED will light GREEN).
