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 guarantee requiring a dBA value or sound data in any other form than sound power level ratings.

2.At a distance of 10 feet from the blower.

1.Certified in accordance with the Unitary Large Equipment certification program which is based on ARI Standard 340/ 360.

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).

3.IPLV = Integrated Part Load Value.

NOTE:All gas units are two-stage heating. First stage is 50% of total.

S.S.E. = Steady State Efficiency (80%) - output divided by input.

For units with VFD and electric or gas heat, the speed of the indoor blower motor continues to be controlled by duct static pressure via the VAV control board.

If there are VAV boxes present in the duct sys- tem, the boxes must be driven to the full-open position using a customer-supplied power source to assure adequate airflow across elec- tric heating elements or gas heat exchanger tubes.
