5.0 Typical Installation There are three (3) common installation methods. 5.1 FULLY DUCTED SYSTEM (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. Fresh air is supplied to bedrooms and principal living areas. The use of bathroom fans and a range hood is suggested to better exhaust stale air.
6.0 Installation INSPECT • • • • THE CONTENTS OF THE BOX 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. If the unit was damaged during shipping, contact your local distributor.
6.0 6.3 Installation PLANNING OF THE (cont’d) DUCTWORK 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. c) Do not use wall cavities as ducts. Do not use branch lines smaller than 4” (102 mm) Ø. d) Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or a range hood.

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.
6.0 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) 010 ! 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.
6.0 6.6 Installation (cont’d) CONNECTING DUCTS TO THE UNIT 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) b) c) d) e) f) Pull back the insulation to expose the flexible duct. Connect the interior flexible duct to the port using a duct tie. Carefully seal the connection with duct tape.
6.0 6.7 Installation (cont’d) INSTALLING THE EXTERIOR HOODS CAUTION All models require an exhaust hood with a backdraft damper. This damper closes when the unit is off and prevents unwanted cold air from entering the house. Choose an appropriate location for installing the exterior hoods: • a minimum distance of 6 feet (1.8 m) between the hoods to avoid cross-contamination • a minimum distance of 18 inches (457 mm) from the ground Make sure the intake hood is at least 6 feet (1.

10.0 Air Flow Balancing WHAT YOU NEED TO BALANCE THE UNIT LOW • A magnehelic gauge capable of measuring 0 to 0.25 inch of water (0 to 62.5 Pa) and 2 plastic tubes. Two ”Flow Measuring Stations” or two flow collars (the size will vary depending on the duct diameter). HIGH FLOW • LOW H W VP0006 VP0005 Flow collar Flow measuring station PRELIMINARY STAGES TO BALANCE THE UNIT • Seal all the unit ductwork with tape. Close all windows and doors.
10.0 Air Flow Balancing (cont’d) BALANCING PROCEDURE 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. (By waiting 10 minutes after plugging the unit in, you are assured that the unit is not in a defrost cycle.) 2.
