Example:
MHCCW04 @ 0.20 ESP produces 325 cfm.
Locate 325 cfm (for the MHCCW04) on the Capacity Adjustment Factors on page 101. (TC =.79 & SC = .75)
Multiply the stated chilled water capacity for the MHCCW04 on page 89 or the hot water capacity on page 94 by the adjustment factors to achieve
the capacity adjustment.
