1. These values have been accessed using a model of sound propagation from a point source into the hemispheric\free field. The
dBA values provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan
manufacture has no way of knowing the details of each system. This constitutes and expectation to any specification or guaran-
tee requiring a dBA value or sound data in any other form than sound power level ratings.

NOTES:
1. Certified in accordance with the Unitary Large Equipment certification program, which is based on ARI Standard 340/360.
2. Rated in accordance with ARI Standard 270.
SEER = Seasonal Energy Efficiency Ratio - the total cooling output in BTU’s during a normal annual usage period for cooling divided by the total electric power input
in watt-hoursduring the same period.
EER = Energy Efficiency Ratio-the cooling capacity in BTU’s per hour (BTUH) divided by the power input in watts at any given set of rating conditions, expressed in
BTUH per watt (BTUH/watt).
COP = Coefficient of Performance - the total heating capacity provided by the refrigeration system, including circulating fan heat but excluding supplementary resistance
(BTU’s per hour) divided by the total electric input (watts) x 3.412.
HSPF = Heating Seasonal Performance Factor - the total heating output during a normal annual usage period for heating divided by the total electric power input during
the same period. (Based on Region IV minimum design heating requirement).
