*Extensive motor and electrical testing on these units ensures that the
full horsepower and watts range of the motors can be utilized with con-
fidence. Using the fan motors up to the ratings shown in this table will
not result in nuisance tripping or premature motor failure. Unit warranty
will not be affected.

*The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should be used in conjunction
with the Fan Performance tables to determine indoor blower rpm and
watts.
