The Lennox 22K60 MWCB012S4-1P is a high-efficiency 1 Ton mini-split wall mount air conditioner designed for residential and light commercial ductless applications. As part of the MWCB family, this indoor wall-mounted unit delivers 12,000 BTU cooling capacity with an impressive 20.50 SEER rating, providing energy-efficient performance and reliable comfort.

Operating on 208-230 VAC, 1 Phase, 60 Hz power, this R-410A mini split air handler is engineered for quiet operation and maximum air circulation. With three-speed airflow settings (324 / 232 / 194 CFM), the unit quickly reaches the desired room temperature while maintaining whisper-quiet performance.

The MWCB wall mount unit features flexible refrigerant piping options (left, right, or rear access), easy front-panel access for wiring and service, and a built-in LED display for operation status and diagnostic codes. The pre-heat function prevents cold air discharge during heating mode, while auto restart restores previous settings after power interruptions. A 30-minute cooling override button allows temporary forced cooling operation directly from the indoor unit.

A cleanable air filter and wireless remote controller are included as standard.
