Furnace In Horizontal Left Position - Trane 5TXCA001AS3HCA Installer's Manual

Installer's Guide
Note: When installing coil onto an S-Series furnaces
in horizontal right or downflow configuration, bend
the flanges downward for a flush fit.

I. FURNACE IN HORIZONTAL LEFT POSITION:
!
CAUTION
Both the coil and furnace must be fully supported. Do not
attempt to suspend the coil using the connection brackets.
1. HORIZONTAL LEFT COIL CONVERSION: While not
required, optional removal of some coil components will
maximize airflow efficiency.
a. Remove the coil by sliding the coil out of the coil
enclosure.
b. Optional but recommended: On 5TXCA009AS and
5TXCD010AS only, remove the (2) outer water diverter
baffles by removing the 5/16" hex head screws. See
Figure 10.
2. HORIZONTAL LEFT (All coils)
The non-condensing furnaces may be laid on either side
for horizontal application. The condensing downflow/hori-
zontal and upflow/horizontal furnaces may only be rotated
onto their left side. Connection brackets for coil/furnace
alignment are included with the furnaces.
a. In horizontal left, the 5TXC coil case is rotated so
the apex of the coil is away from the furnace and the
auxiliary drain pan is now on the lower side.
b. The two piece baffle ships installed on the coil and is
required for horizontal left applications.
c. The base of the coil enclosure is placed flush against
the downflow/horizontal furnace. Upflow/horizontal
condensing furnaces have the coil match the top
flange.
d. There are three brackets included with the non-
condensing downflow furnace which are used to
connect the furnace and coil together. See Figure 11.
e. Two brackets are used to attach the rear of the coil and
furnace and one bracket is used to attach the front.
The rear brackets will use existing screws on the coil
enclosure (two on each side at the bottom). Each of the
rear brackets will be attached with the wide side of the
bracket resting on the top and bottom of the horizontal
coil and furnace (see Figure 12). Four additional
screws will be used to attach each rear bracket.
f. The front bracket is positioned as close to the center
as possible with the narrow edge against the coil
enclosure and the wide edge against the furnace. Two
screws each are driven into the coil enclosure and
furnace.
g. There is a splash guard packaged with the coil. This
guard is for horizontal left coil installation only. The
guard has a bend which is inserted into the front
channel of the horizontal drain pan on the outlet
air side of the coil case. The guard is then rotated
downward until it rests in the drain pan. One sheet
metal screw is driven through the coil case duct flange
on the front side and into the splash guard side hole.
See Figure 13.
h. Pull refrigerant sensor and clip up and away from the
primary drain pan and remove it from the pan. Secure
sensor to secondary pan using provided clip. Sensor
should be positioned close to secondary drain lines.
See Figure 6 for detail. Ensure sensor wiring harness
is clear of refrigerant lines to avoid damage during
field connection brazing. In some models, the wire tie
attaching the sensor harness to the TXV body may
need to be snipped to allow for wire harness to be
extended for correct sensor palcement.
