All units tested equipped with MERV 8 filters. Appropriate supply (SG) and return (RG) grilles installed during testing.
Pressure switch adjustment may be necessary due to variations in filter type, installation and room pressure.
Bard recommends filter switch be set at 50% filter blockage or less. Higher settings may significantly hinder unit
performance.
