This application uses a devoted duct system for the exhausting of stale air accumulated in the home. The fresh air is dumped into the return air duct and is distributed thru the home by the existing supply air ductwork of the forced air system. Make sure when using this application that your fresh air duct connection to the forced air system return air duct is at least 3 feet from the forced air system. You should check with your local code or the forced air system’s manufacturer. The forced air system’s blower does not essentially have to run when the unit is in continuous mode, but recommended for maximum efficiency. CAUTION Insure the unit runs in conjunction with forced air system NOTE Dwellings with multiple forced air systems, we recommend one HRV/ERV per system.
When using this application make sure that there is minimum 6 feet between the fresh air and exhaust air connections of the HRV or ERV in the return air duct. Supply air from HRV or ERV must be at least 3 feet from the forced air system. Can be different from a region to another. You should check with your local code or the forced air system’s manufacturer. CAUTION The HRV and forced air system must be in continuous mode, to achieve maximum comfort and to avoid cross-contamination. Due to temperature differential between unconditioned areas and the rest of the dwelling, all ducts must be fully insulated. The unconditioned areas temperature must always be above 0°C (32°F). NOTES Fresh air must always be down-stream from the exhaust air in the return air duct of the forced air system. Installation of an HRV/ERV is not recommended for unconditioned areas (attic or crawlspace)
