There is no conversion required to reverse from right to left
application. Attach the duct flanges to the discharge side of
the unit. If the coil and furnace combination are not similar in
depth and width, use a field-supplied transition to center the
furnace and coil openings (see figure 3). The supplied Z-bracket
attachment should be used to attach the coil to a narrower
furnace when the furnace is one size smaller than the coil (i.e.
coil height = 17.5-inches and furnace width = 14-inches) (See
figure 3). Figure 3a indicates incorrect coil/furnace attachment method.
Duct Flange Att achment
1. Remove the shipping bracket spanning the A-Coil apex
to the rear of the wrapper on all models prior to installation.

Condensate Drain Piping
When coils are installed above ceilings, or in other locations
where damage from condensate overflow may occur, it is MAN-
DATORY to install a field-fabricated auxiliary drain pan under
the coil cabinet enclosure. Drain lines from the auxiliary pan
must be installed and terminated so that the homeowner can
see water discharges.
The coil drain pan has a primary and an optional secondary
drain with 3/4" NPT female connections. The connectors required can be 3/4" NPT male either PVC or metal pipe and
should be hand tightened to a torque of no more than 37 in-lbs.
to prevent damage to the drain pan connection. An insertion
depth between .355 to .485 inches (3-5 turns) should be expected at this torque. If using a copper drain line, solder a
short piece of pipe to the connector before installing a drain
fitting. DO NOT over torque the 3/4” copper connector to the
plastic drain connection.

1. Ensure drain pan hole is NOT obstructed.
2. To prevent potential sweating and dripping on finished
space, it may be necessary to insulate the condensate
drain line located inside the building. Use Armaflex® or
similar material.
A Secondary Condensate Drain Connection has been provided
for areas where the building codes require it. Pitch the drain
line 1/4" per foot to provide free drainage. Insulate drain lines
(primary and secondary) located inside the building to prevent
sweating. Install a condensate trap in the primary drain line to
ensure proper drainage. If the secondary line is required, run
the line separately from the primary drain and end it where it
can be easily seen.
NOTE: Water coming from this line means the coil primary
drain is plugged and needs clearing.

CAUTION
If secondary drain is not installed, the secondary access
must be plugged.
NOTE: Trapped lines are required by many local codes. In the
absence of any prevailing local codes, please refer to the
requirements listed in the Uniform Mechanical Building Code.
A drain trap in a draw-through application prevents air from
being drawn back through the drain line during fan operation
thus preventing condensate from draining, and if connected to
a sewer line to prevent sewer gases from being drawn into the
airstream during blower operation. In a blow-through application the drain trap prevents conditioned air from escaping. It is
permissible in this application to use a shallow trap design
sometimes referred to as a running trap.

The depth of a running trap (Figure 5) should be either 1" or a
depth that permits unrestricted condensate drainage without
excessive air discharge.
Field experience has shown condensate drain traps with an
open vertical Tee between the air handler and the condensate
drain trap can improve condensate drainage in some applications, but may cause excessive air discharge out of the open
Tee. The manufacturer does not prohibit this type of drain but
we also do not recommend it due to the resulting air leakage.
Regardless of the condensate drain design used, it is the
installer’s responsibility to ensure the condensate drain system is of sufficient design to ensure proper condensate removal from the coil drain pan.

pipe cutter to remove the closed end of the spun closed suction line.
To avoid overheating after brazing, quench all welded joints
with water or a wet rag.
For the correct tubing size, follow the specification for the condenser/heat pump
WARNING
The coil is shipped under press ure. Follow these
instructions to prev ent in ju ry.
CAUTION
Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportiona l to the s ize of th e tub e. S erv ice p ersonn el m u st
use the appropriate heat level for the size of the tube being
brazed.
NOTE: Tubes of smaller size require less heat to bring the
tube to brazing temperature before adding brazing alloy. The
use of a heat shield when brazing is recommended to avoid
burning the serial plate or the finish on the unit.

Special Instructions
This coil comes equipped with a check style flowrator for refrigerant management. For most installations with matching applications, no change to the flowrator orifice is required. However, in mix-matched applications, a flowrator change may be
required. See the Piston Kit Chart or consult your local distributor for details regarding mix-matched orifice sizing. If the
mix-match application requires a different piston size, change
the piston in the distributor on the indoor coil before installing
the coil and follow the procedure shown below.
1. Loosen the 13/16 nut 1 TURN ONLY to allow high pressure tracer gas to escape. No gas indicates a possible
leak.
2. After the gas has escaped, remove the nut and discard
the plastic or brass cap.
3. Remove the check piston to verify it is correct and then
replace the piston. See piston kit chart in instructions.
4. Use a tube cutter to remove the spin closure on the suction line.
5. Slide the 13/16 nut into place on the tailpiece supplied in
the literature bag or with the unit.
CAUTION
Excessive torque can cause or ifices to stick. Use the proper
torque se tting s wh en tig h ten in g orific es .
