2. 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 Evaporator-Fan Motor Performance table on page 55 for addi-
tional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
local representative for details.
