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 af- fected. For additional information on motor performance, refer to Table 4.

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

4.To convert watts to bhp:

bhp =

watts input x motor efficiency
