2. TYPICAL INSTALLATIONS NOTE: Installation may vary according to the model number and the position; normal or reverse (Solo units only) in wich the unit is installed. 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.
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) 3.7 INSTALLING THE EXTERIOR HOODS Choose an appropriate location for installing the exterior hoods: 6” ø (152 MM) EXHAUST HOOD • At a minimum distance of 6 feet (1.8 m) between the hoods to avoid cross-contamination INTAKE HOOD • At a minimum distance of 18 inches (457 mm) from the ground 18” (457 MM) 6’ (1.8 M) ! WARNING Make sure the intake hood is at least 6 feet (1.
