kW — Total Fan Motor Power Input (kilowatts)

NOTES:

1.Above fan performance is based upon coil and deducted casing losses only.

2.External static pressure (ESP) is measured in inches water gage (in. wg).

3.Interpolation is permissible. Do not extrapolate.

4.Condenser fan on unit size 024 only, is direct drive.

5.Minimum one turn open of motor pulley is required on unit sizes 036 and 060.

6.Number of turns open applies to field setting of motor pulley.

7.Factory setting as follows: 036, 4 turns open; 048, 2 turns open; 060, 5 turns open.
