4. Maximum continuous bhp is 3.7 and the maximum continuous
watts are 3313. Extensive motor and electrical testing on these
units ensures that the full range of the motor can be utilized with
confidence. 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. See Indoor-Fan Motor Performance
table on page 52 for additional information.
