Reading the model number
CB is an air handler, K is R-454B, and 47 is the Elite Series with the Quantum coil. UH is upflow/horizontal, E is the high-efficiency constant torque motor, and T is the factory check/expansion valve. 048 is 4 tons, 230 is 208/230V single-phase, and 71 means an R-454B valve is installed.
What it pairs with
The AHRI Directory lists it with these Lennox units we sell: EL15KC1, EL16KC1, EL18KCV, EL22KCV, ML13KC1, ML14KC1, and ML17KC2 air conditioners and EL16KP1, EL18KSLV, EL19KPV, EL21KLV, and ML14KP1 heat pumps. Listed ratings run from 13.8 to 19.5 SEER2, and the best match is the EL21KLV-048-230 heat pump.
For electric heat, Lennox lists ECB47 heaters from 4 to 25 kW for this size: 4, 5, 6, 8, and 9 kW with a terminal block or a circuit breaker; 12.5, 15, 20, and 25 kW with a circuit breaker. Three-phase ECB47 kits are listed for this size too.
Sizing and fit
Downflow needs Lennox's 28B60 downflow kit, and horizontal left-hand discharge needs the horizontal drain pan moved. Match the air handler to your outdoor unit's tonnage.
Warranty and registration
HVAC USA is an authorized Lennox reseller, and everything we sell is new factory equipment. Your full Lennox warranty applies when a licensed, manufacturer-certified contractor installs your system and registers it within 60 days.
