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 4TXCcoil case is rotated so
the apex of the coil is away from the furnace and the
auxiliary drain pan is now on the lowerside.
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-
condensingdownflow furnace which
are used to
connectthe furnace and coil together. See Figure 9.
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 resti.1g
on the top and bottom of the horizontal
coil and furnace (see FigurE 10). Fouradditional
screws will be used to attach each rear bracket.
f. The front bracket is positioned as close to the center
as possiblewith 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 leftcoil 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 11 .
Standoffsandscrews
(See Figure 3) are included with the cased
coils for attachment to the furnace.There are clearance alignment
holes near the bottom of the coil wrapper. Drill screws are used
to engage the top flanges ofthe furnace.The standoff is inserted
intothe cabinet alignment hole (See Figure
3) .The drill screws are
inserted through the standoffs then screwed into the furnace top
flange. The co il is always placed downstream ofthe furnace airflow.
The coil and furnace must befully supported when used
in the hori-
zontal position.The standoffs and screws are strictly for securing
alignment, notfor support in horizontal.

Installer's Guide
I. INSTALL I NG/BRAZING REFRIGERANT LINES
A CAUTION
Do 1!KJI open refrigerantvalve at the outdoor unit until the
refrigerantlines
and coil havebeen brazed, evacuated, and
leakchecked. Thiswouldcausecontamination of therefriger-
ant or possibledischarge of refrigerant to theatmosphere.
1. The following·steps are to be considered when installing
the refrigerant lines:
a. Determinethe most practical way to run the lines.
b. Considertypes of bends to be made and space
limitations.
c. Route the tubing making all required bendsand
properly secure the tubing before making final
connections.
NOTE: Refrigerantlinesmustbe isolated from
the structure and
the holes must
be sealed weather tight afterinstallation.
IMPORTANT:
Do not unsealrefrigerant tubing until ready to fit refriger-
ant lines.
Thereisonlyaholdingcharge of dryairintheindoorcoil, therefore
noloss
of operating refrigerant charge occurswhenthe sealing
plugs are removed.
NOTE:
TXV bulb MUSTbeprotected(wrapped with wetrag) or
removed, while brazing the tubing. Overheating of the
sensing
bulb will affectthe functionalcharacteristics and
performance of the comfort coil.
1. Remove both rubber plugs from the indoorcoil.
2. Field supplied tubing should be cut square, round and free
of burrs at the connecting end.Clean the tubing to prevent
contaminants from entering the system.
3. Run the refrigerant tubing into the stub
tub e sockets of the
indoor unitcoil.
PAINTED AREAS OF THE UNIT MUST BE SHIELDED
DURING BRAZING.
4. Flow a small amount of nitrogen through the tubing while
brazing.
5. · Use good brazing technique to make leakproof joints.
6. Minimize the use
of sharp 90 degree bend s.
7. Insulate the suction line and its fittings.
8. Do NOTallow un-insulated lines to come intocontact with
each other.
5.

Installer's Guide
Capillary tubes will come
out the top
of bulb when
positioned correctly.
Figure 12
When replacing the TXV bulb, reinstall the bulb in the
proper orientation.
Somemodels will use a springsteel clip to attach the TXV
bulb, and some models will use a hose clamp. When sup-
plied with a hose clamp, the clamp should be "snug" but
not "tight" -the specification is to torque the hose clamp
to
20 +1-5 in-lbs.
9. Wrapthe
TXV with insulation afterthe hose clamp or spring
clip has been installed.
J. LEAK CHECK
1. Using a manifold gauge, connect an external supply of dry
nitrogen to the gauge port on the liquid line.
2. Pressurize the connectinglinesand indoorcoil to 150PSIG
maximum.
3. Leak check brazed line connections using soap bubbles.
Repairleaks (if any) after relieving pressure.
4. Evacuate andcharge thesystem perthe instructions pack-
aged with the outdoor unit.
K. CONDENSATE DRAIN PIPING
Condensate drain connections are located in the drain pan at
the bottom of the coil/enclosure assembly. The female threaded
fitting protrudesoutside
of theenclosurefor externalconnection.
A field fabricatedtrap is not required for properdrainage
due to
thepositivepressure of thefurnace; however, it is recommended
to preventefficiency loss of conditioned air.
1. Thedrainholeinthedrainpanmust
be cleared of allinsulation.
2. Insulate the primary drain line to prevent sweating where
dew point temperatures may be met. (Optional depending
on climate and application needs)
3. Connect the secondary drain line to a separate drain line
(notrap is needed in this line).
6
L. CLEANING THE COIL
The two piece door allows removal of the outer casing doors
without interference from refrigerant
or condensate lines. Once
the outer doors are removed the inner coil panels can be easily
removed. The insideandoutside of the coilcanbe easilycleaned
witha brushandvacuumwith
the panelsremoved.SeeFigure13.
The foil covered insulation should be wiped down and residual
dirt and dust should·.be vacuumed up to maintaingoodairqual-
ity. See Figure 14.
