Watts — Input Watts to Motor
NOTES:
1, Factory shipped fan speed is 1092 rpm. The range of the stand
ard evaporator-fan motor is 978 to 1285 rpm. Other rpms may
require a field-supplied drive.
2 Static pressure iosses (i.e., economizer, eiectric heater) must be
added to external static pressure before entering Fan Perfor
mance table.
3. To convert watts to bhp, use the following equation:
„Watts X motor efficiency
^ 746
Motor efficiency: Horsepower — Maximum Continuous Watts:
0 84 3 hp - 3065
4 Interpolation is permissible Do not extrapolate.
5. Fan performance is based on wet coils, clean filters, and casing
losses.
6. Extensive motor and drive testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the watts rating shown will not result in nui
sance tripping or premature motor failure Unit warranty will not
be affected.
