capacities of the compressor at high and low speeds. To select the
recommended airflow and for adjustments to the manual switches
labeled SW1, AiC and CF on the control board refer to the furnace
Installation, Start-Up, and Operating Instructions. The
58CVAi58CVX utilizes a control center that allows the installing
technician to select the proper airflows. The AC switch deter-
mines the airflow during high speed compressor operation. Air-
flow for high and low speed can be calculated at either 350 CFM
per ton or 400 CFM per ton based on the positions of SW1-5.
