COIL REQUIREMENT!
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. See Installer's Guide for more information.
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning
equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person
could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that
are attached to the equipment.
