Application Information
Coil must be installed downstream (discharge air) of the fur-
nace. Allow a minimum of 18" from the furnace outlet to the
coil for adequate transition. This coil is bi-directional coil and
can be installed in either the left or right direction. The coil is
factory shipped for left-side application. Determine the coil di-
rection by the side that allows the best access.

Condensate Drain Piping
In all cooling applications, a secondary drain pan should be
provided by the installer and placed under the entire unit with a
separate drain line properly sloped and terminated in an area
visible to the owner. This secondary drain pan can provide ex-
tra protection to the area under the unit should the primary
drain plug up and overflow. As expressed in our product war-
ranty, we will not be liable for any damages, structural or other-
wise due to the failure to follow this installation requirement.
The coil drain pan has a primary and an optional secondary
drain with 3/4" NPT female connections. The connectors re-
quired 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 ex-
pected 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 to 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 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.
If secondary drain is not installed, the secondary access
must be plugged.
CAUTION
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 applica-
tion 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 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 applica-
tions, but may cause excessive air discharge out of the open
3
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 sys-
tem is of sufficient design to ensure proper condensate re-
moval from the coil drain pan.

Do not use the coil pan shipped with the unit on OIL
furnaces or any application where the temperature of
the drain pan may exceed 300ºF. A field fabricated
metal drain pan should be used for these type of appl-
ications. Failure to follow this warning may result in
property damage and/or personal injury.
WARNING
Install a trap in the drain line below the bottom of the drain pan
(required). 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 con-
nection. Using a wet rag or heatsink material on the short
piece to protect plastic drain pan, complete the drain line in-
stallation.
Horizontal Coil Water Blow-Off Bracket
This coil is factory shipped with a horizontal water blow-off
bracket installed on the left side for “horizontal-left” installation
on gas furnaces. If the gas furnace is to be installed horizon-
tal-right, the water blow-off bracket must be moved to the right
side. To move the bracket, slide the bracket off the left edge of
the drain pan and slide it back on the right (see Figure 5).

Refrigerant Lines
A quenching cloth is strongly recommended to
prevent scorching or marring of the equipment
finish when welding close to the painted surfaces.
Use brazing alloy of 5% minimum silver content.
WARNING
All cut ends are to be round, burr free, and cleaned. Any
other condition increases the chance of a refrigerant leak.
Use a 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 con-
denser/heat pump
The coil is shipped under pressure. Follow these
instructions to prevent injury.
WARNING
Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportional to the size of the tube. Service personnel must
use the appropriate heat level for the size of the tube being
brazed.
CAUTION
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 refrig-
erant management. For most installations with matching ap-
plications, no change to the flowrator orifice is required. How-
ever, in mix-matched applications, a flowrator change may be
required. See the Goodman piston kit chart or consult your
local distributor for details regarding mix-matched orifice siz-
ing. 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.
To prevent feeder tube damage, hold the distributor body
with a 3/4" open end wrench when removing or replacing
the 13/16" flare nut.
CAUTION
1. Remove the valve core to allow high pressure tracer gas
to escape. No gas indicates a possible leak.
2. Remove the 13/16" flare nut and tailpiece.
3. Unsweat the access fitting on the tailpiece
4. Remove the check piston to verify it is correct and then
replace the piston. See piston kit chart in instructions.
5. Use a tube cutter to remove the spin closure on the suc-
tion line.
6. Slide the 13/16" flare nut over the tailpiece.
7. Braze tailpiece to the lineset liquid tube.
8. Insert the suction line into the connection, slide the insu-
lation at least 18" away from the braze joint. Braze suc-
tion line.

Aluminum Indoor Coil Cleaning
(Qualified Servicer Only)
This unit is equipped with an aluminum tube evaporator coil.
The safest way to clean the evaporator coil is to simply flush
the coil with water. This cleaning practice remains as the
recommended cleaning method for both copper tube and alu-
minum tube residential cooling coils.
An alternate cleaning method is to use one of the products
listed in the technical publication TP-109 (shipped in the lit-
erature bag with the unit) to clean the coils. The cleaners
listed are the only agents deemed safe and approved for use to
clean round tube aluminum coils. TP-109 is available on the
web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical
cleaners.
