NOTES:

1.Standard low-medium static drive range is 1066 to 1283 rpm, Alternate high-static drive range is 1332 to 1550. Other rpms require a field- supplied drive,

2.Maximum continuous bhp is 10.2 (208/230, 575 v) or 11.8 (460 v) and the maximum continuous watts are 9510 (208/230, 575 v) or 11,000 (460 v). Do not adjust motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum operating cfm.

3.Static pressure losses (i,e., economizer) must be added to external static pressure before entering Fan Performance table,

4.Interpolation is permissible. Do not extrapolate,

5.Fan performance is based on wet coils, clean filters, and casing losses. See Tables 21-23 for accessory/FlOP static pressure information,

6.Extensive motor and drive testing on these units ensures that the full horsepower and watts range of the motor can be utilized with confi- dence, Using fan motors up to the watts or bhp rating shown will not

result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

7.Use of a field-supplied motor may affect wiring size. Contact your Carrier representative for details,
