Typical Installation There are three (3) common installation methods. 5.1 F ULLY UCTED YSTEM (Primarily for homes with radiant hot water or electric baseboard heating. See figure 1.) Moist, stale air is exhausted from the high humidity areas in the home, such as bathrooms, kitchen and laundry room.
Installation NSPECT THE ONTENTS OF THE • Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, door latches, door hinges, dampers, duct collars, cabinet, etc. • Inspect the interior of the unit for damage. Ensure that the fan motor assembly, recovery core, insulation, dampers, damper actuator and drain pan are all intact.
Installation (cont’d) 6.3 P LANNING OF THE UCTWORK a) Follow the instructions in Section 6.4 below to determine the appropriate duct diameters for your system. b) Keep it simple. Plan for a minimum number of bends and joints. Keep the length of insulated duct to a minimum.

Installation (cont’d) 6.5 Installing the Ductwork and Registers (cont’d) 6.5.3 Simplified installation (Volume Ventilation) (as illustrated in Section 5.3) 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 connection to the furnace ducts (Method 1), these ducts must be sized to support the additional airflow produced by the HRV/ERV.
Installation (cont’d) 6.6 C ONNECTING UCTS TO THE Insulated flexible duct Use the following procedure for connecting the insulated flexible duct to the ports on the unit (exhaust to outside and fresh air from outside). a) Pull back the insulation to expose the flexible duct. b) Connect the interior flexible duct to the port using a duct tie.

10.0 Air Flow Balancing (cont’d) ALANCING ROCEDURE 1. Set the unit to high speed. Make sure that the furnace blower is ON if the installation is in any way connected to the ductwork of the cold air return. If not, leave furnace blower OFF. If the outside temperature is below 0°C / 32°F, make sure the unit is not running in defrost while balancing.
