6 Installation Instructions The RNC120F model can be setup in two different airflow configurations as illustrated in the engineering data sec- tion of the manual. Because of this, it is extremely important that the unit be connected properly. The remote electrical control box contains two receptacles labelled “Fan Connection A” and “Fan Conne[...]

7 Location Selection The HRV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV would be located in the mechanical room or an area close to the outside wall where the weather hoods will be mounted. If a basement area is not convenient or does not exist, a utility or laundry room may be us[...]

9 Air Duct Design and Installation A well designed and installed ducting system will allow the HRV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as pos- sible. See Installation Diagrams for various installation options. The inner and outer liners of the flexible insulated duct must be clamped to the sleeve[...]

10 Stale Air Exhaust System The stale air exhaust system draws air from the points in the house where the worst air quality problems occur. Stale air ducts should be installed in the bathroom, kitchen, and laundry room. Applications such as green- houses, atriums, swimming pools, saunas, etc. have unique ventilation requirements which should be add[...]
