036-21024-006 Rev. D (0403)Unitary Products Group 9NOTES:1. For condensing unit only. Does not include effect of evaporator motor power or heat.2. Performance based on 15° superheat and 15° sub-cooling at condensing unit.a. Increase capacity 1% for each 2° increase in sub-cooling.b. Decrease capacity 1% for each 2° decrease in sub-cooling.3. Sub-cooling in excess of 20° may result in excessively high condensing temperature with air on condenser above 115°F.Maximum recommended condensing temperature is 140°F.TYPICAL INSTALLATIONCOOLING PERFORMANCEMODELSUCT.
