3. PLANNING THE INSTALLATION The Guardian Plus units are versatile appliances capable of delivering filtered air (model GSFH1K) or both filtered and fresh air to your home (models GSVH1K and GSHH3K). Because each installation is different, it is recommended you take the time to plan your installation.
3. PLANNING THE INSTALLATION 3.1 PLANNING OF THE DUCTWORK • Keep it simple. Plan for a minimum of bends and joints. • Keep the length of insulated ducts to the outside of home to a minimum (not for HEPA Filtration model GSFH1K). • Do not ventilate crawl spaces or cold rooms. • If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level. Use the following table to plan the flexible ducts length.
