CAUTION
!
Failure to follow this Caution could result in property damage or personal injury. 4GXC* and
4MXC* coils installed on upflow furnaces in vertical, horizontal left, or horizontal right
orientations without a factory installed metal drain pan shield must use a MAY*FERCOLKITAA
kit. Coils installed on upflow furnaces must have drain pans that are suitable for 400° F
(205°C) or have a metal drain pan shield. Downflow furnaces do not require a metal drain pan
shield or the use of the MAY*FERCOLKITAA kit.
