To install cased coils in downflow applications, follow the instructions
below, (Downflow Coil Installation on p5).
To install cased coils in horizontal applications, follow the instructions
below, (Horizontal Coil Installation on p5).
See Table 1 for coil connection options. Refer to instructions for
placement of coil casing on furnace.
NOTE: We recommend a 4" transition for peak performance, but it is
not required unless stated.

CAUTION
!
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in property damage.
Installing coils rotated 90° from the front of the furnace, in upflow,
downflow, or horizontal applications, may cause water blow-off or coil
freeze-up due to the concentration of air on one slab of the coil or lack
of air to a slab of the coil. It is required that on this type of application,
a field-supplied adapter be placed between the coil and furnace to allow
air to distribute properly between all slabs of the coil.
