PERFORMANCE DATA - 1.5 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 15ºF subcooling and 15ºF superheat at the Outdoor Unit base valves.
a. Increase capacity by 1% for each 2ºF increase in subcooling.
b. Decrease capacity by 1% for each 2ºF decrease in subcooling.
3. Maximum recommended condensing temperature is 140ºF.
