The Lennox DLSC CBK48MVT-048 is a 4-ton, fully digital, variable-speed air handler built for Lennox's highest-performance residential systems.
It's engineered specifically for R-454B, the next-generation low-GWP refrigerant, and includes a refrigerant detection system to meet current safety requirements for this refrigerant class.
At its core is a 1 HP, variable-speed ECM blower motor, delivering a wide airflow range of 1,230 to 2,200 CFM to match varying load demands, with a minimum speed down to 450 CFM for Smart Zoning applications. The unit draws a maximum of 10 amps minimum circuit ampacity on a 208/230V single-phase supply, with a 15-amp maximum overcurrent protection rating. The control board supports two-stage heating and cooling operation, with optional electric heat strips staged up to three ways standard, or four ways with Lennox's EvenHeater control.
Inside, the Quantum coil uses enhanced aluminum tube-and-fin construction in a 3-row A-coil configuration for efficient, reliable heat transfer. The cabinet is 4-way multi-position, shipping standard for upflow or horizontal-right installation and field-convertible to downflow or horizontal-left.
Pairing seamlessly with the Lennox S40 Smart Thermostat and compatible outdoor units, the CBK48MVT-048 delivers precise comfort control backed by Lennox's 10-year limited warranty on covered components.
