1. Differentials for Cooling Operation (IDB, COMP, & ODF) are logarithmically calculated from the horizontal flow sound test.
• Tested in accordance with ARI Standard 260-2001. Refer to 2001 Standard for Sound Rating of Ducted Air Moving and Conditioning
Equipment.
• Testing datum includes effect of standard inlet air filters.
• Test duct dimension: 18 in. wide x 28 in. high x 8 ft. long, no elbows.
• Test duct termination is flush with reverberant room wall.
• Duct end (sound reflection) corrections included: (7.2, 3.4, 1.2, 0.4, 0.1, 0, 0, 0) dB at (63, 125, 250, 500, 1k, 2k, 4k, 8k) Hz respectively.
