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

*The static pressure must be added to external static pressure. The sum and the evaporator
entering-air cfm should then be used in conjunction with the Fan Performance tables to deter-
mine blower rpm and watts.
NOTE: The rooftop unit return air configuration determines the economizer configuration (verti-
cal or horizontal).
