Condenser only performance data notes
• For outdoor unit (condenser) performance only. Data does not include the effects of air handler
power or heat.
• Performance based on 15°F subcooling and 15°F superheat at the outdoor unit base valves:
a. Increase capacity by 1% for each 2°F increase in subcooling.
b. Decrease capacity by 1% for each 2°F decrease in subcooling.
• Maximum recommended condensing temperature is 140°F.
