WARNING
FIRE HAZARD!
Failure to follow this Warning could result in property damage, severe personal
injury, or death.
This Warning applies to installations with a ammable refrigeration system.
The furnace must be powered except for service. The furnace shall be installed
and connected according to installation instructions and wiring diagrams that
are provided with the evaporator coil.
NNoottee:: Graphics in this document are for representation
only. Actual model may differ in appearance.
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.
