BLK Fig. 13 - Transformer Connections A94067 z_ CAUTION: The conversion of the fan coil to downflow requires special procedures for the condensate drains on both A coil and Slope units. The vertical drains have an overflow hole between the primary and secondary drain holes. This hole is plugged for all applications except downflow, but must be used for downflow. During the conversion process, remove the plastic cap covering the vertical drains only and discard.
