This manual introduces the installation method of the VER200 energy recovery ventilator.
This guide provides step-by-step instructions for installing the Fantech VER200 energy recovery ventilator, including determining airflow needs based on room count and floor area. It details three installation configurations: fully dedicated, partially dedicated, and simplified options, with diagrams and safety notes. The guide also covers exterior and interior ducting, airflow balancing, low-voltage control systems, and maintenance.
Installation must comply with local building codes or ASHRAE standards. Compatibility with furnaces or air handlers must be verified post-installation using the balancing procedure. Special considerations are given for frost prevention and cold-air introduction when ERV is off.
The airflow requirement is calculated by multiplying the number of rooms by 5 L/s (10 CFM) for bedrooms, living rooms, and other rooms, with additional 10 L/s (20 CFM) for bathrooms if they require local exhaust ventilation.
A minimum separation of 1 meter (3 feet 3 inches) is recommended between the two direct connections to prevent exhausting fresh air.
If the ERV is turned off during winter, install a motorized damper between the ERV's supply air and the furnace's return air duct that closes when the ERV is not operating.
