What plenum size to connect to coil for upflow configuration.

For the MVP-24-HP-C-230A00-O coil paired with the MVP-24-HP-MUAH-230A00-O air handler in an upflow configuration, the supply plenum should connect to the unit's factory supply opening, which is approximately 15-5/8 inches wide by 10-1/4 inches deep. In practice, installers typically use a 16-inch by 10-inch plenum connection or a transition that starts at that size and expands to a larger plenum as required by the duct system's airflow and static pressure design.
