PERFORMANCE DATA - 4 TON
Multipliers for determining the performance with other indoor sections.
NOTE:
For dry bulb temperatures different than those listed (between 73-87 °F), sensible capacity increases by 1060 BTUH per 1000 CFM per degree above the listed
temperature and decreases by 1060 BTUH per 1000 CFM per degree below the listed temperature.

Notes:
1. For Outdoor Unit (Condenser) performance only. Data does not include the effects of air handler power or heat.
2. 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.
3. Maximum recommended condensing temperature is 140°F.
