NOTES:
1. Maximum allowable fan speed is 1100 rpm for unit size 300;
1200 rpm for all other sizes.
2. Fan performance is based on deductions for wet coil, clean 2-in.
filters, and unit casing. See table on page 70 for factory-supplied
filter pressure drop.
3. The medium-static drive and standard motor combination is not
available for 300 size. Use alternate motor if medium-static drive is
required for these sizes.
