ESP Ð External Static Pressure (in. wg)

NOTES:

1.Values include losses for ®lters, unit casing, and wet coils.

2.Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with con®dence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. For additional information on motor performance, refer to Table 4.

3.Use of a ®eld-supplied motor may affect wire sizing. Contact your distributor to verify.

4.To convert watts to bhp:

bhp =	watts input x motor efficiency
	746
Motor efficiency = .63

NOTES:

1.Boldface indicates a ®eld-supplied drive is required. (See Note 4.)

2.Maximum usable watts input is 1000. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with con®dence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. For additional information on motor performance, refer to Table 4.

3.Values include losses for ®lters, unit casing, and wet coils.

4.Alternate motor drive range: 760 to 1090 rpm. All other rpms require ®eld-supplied drive.

5.To convert watts to bhp:

bhp =

watts input x motor efficiency

746

Motor efficiency = .75
