* DX coil configuration (S = Standard, L = Large) is identified by the eighth digit of the RPS/RDT or RFS model number, found on the unit nameplate.
For example, DX = L for unit model number RFSO6OCLY.
** Condenser pumpdown capacity is the total charge for both circuits and is based on volume between condenser entrance and liquid linesolenoid at 90ºF, 90% full.
