Always verify that the systems airflow is not impaired by the filtering system that has been installed, by performing a temperature rise and temperature drop test. Keep the air filters clean at all times. Vacuum dirt from filter, wash with detergent and water, air dry thoroughly and reinstall. See Table 10 and Figures 24 and 25 for proper filter sizes and locations. 1. 14”- 50,000 BTUH unit requires removal of 31/” segment of filter and 2 frame to get proper width for a bottom filter. 2. 21”-100,000 BTUH unit requires removal of 31/” segment of filter and 2 frame to get proper width for a side filter. 3. 241/”-125,000 and 150,000 BTUH 2 units require removal of 7” segment of filter and frame to get proper width for a side filter
