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.

2. EER = Energy Efficiency Ratio at full load - the cooling

capacity in Btu’s per hour (Btuh) divided by the power

input in watts, expressed in Btuh per watt (Btuh/watt).
