The net capacity data has fan motor heat factored in for all ratings and the entering air conditions of 75°F (23.9°C), 45% RH, is the standard rating condition for
ASHRAE 127-2007. All capacities are nominal values; actual performance will be ±5%.
* Hot Gas Reheat operates only during dehumidification. Capacity shown is offset by cooling capacity; cannot be used for space heating and is for reference only.
