NOTES:
* Factory Set Cooling Speed
** Factory Set Heating Speed
1. Two openings are recommended for airfl ows above 1,600 CFM if fi lter(s) is(are) adjacent to furnace.
2. Temperature rises in the table are approximate. Actual temperature rises may vary.
3. Temperature rises shaded in gray are for reference only. These conditions are not recommended.
