Condensing unit only ratings are at 45 F SST and
95 F entering-air temperature.
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).
EER; condensing unit only ratings based on 45º F SST and 95ºF entering outdoor air temperature.
