5 Pre-Installation Considerations
5.1 Preparation
Keep this document with the unit. Carefully read all instructions for the installation prior to installing product. Make sure each
step or procedure is understood and any special considerations are taken into account before starting installation. Assemble all
tools, hardware and supplies needed to complete the installation. Some items may need to be purchased locally. Make sure
everything needed to install the product is on hand before starting.
5.2 System Matches
The entire system (combination of indoor and outdoor sections) must be manufacturer approved and Air-Conditioning, Heating,
and Refrigeration Institute (AHRI) listed. NOTE: Installation of unmatched systems is not permitted. Damage or repairs due to
installation of unmatched systems is not covered under the warranty.
5.3 Interconnecting Tubing
Give special consideration to minimize the length of refrigerant tubing when installing air handlers. Refer to Remote Cooling/Heat
Pump Service Manual RS6200006, and TP-107 Long Line Set Application R-410A for tubing guidelines. If possible, allow adequate
length of tubing such that the coil may be removed (for inspection or cleaning services) from the cabinet without disconnecting
the tubing.
5.4 Clearances
The unit clearance from a combustible surface may be 0". However, service clearance must take precedence. A minimum of 24" in
front of the unit for service clearance is required. Additional clearance on one side or top will be required for electrical wiring
connections. Consult all appropriate regulatory codes prior to determining final clearances. When installing this unit in an area
that may become wet (such as crawl spaces), elevate the unit with a sturdy, non-porous material. In installations that may lead to
physical damage (i.e. a garage) it is advised to install a protective barrier to prevent such damage. Always install units such that a
positive slope in condensate line (1/4" per foot) is allowed.

5.5 Horizontal Applications
If installed above a finished living space, a secondary drain pan (as required by many building codes), must be installed under the
entire unit and its condensate drain line must be routed to a location such that the user will see the condensate discharge.
6 Installation Location
NOTE: These air handlers are designed for indoor installation only.
The AVPTC**14** product line may be installed in one of the upflow, downflow, horizontal left or horizontal right orientations as
shown in Figures 2, 3, 4 and 5. The unit may be installed in upflow or horizontal left orientation as shipped (refer to specific sections for
more information).
Minor field modifications are necessary to convert to downflow or horizontal right as indicated in below sections.
6.1 Upflow Installation
No field modifications are mandatory however to obtain maximum
efficiency, the horizontal drip shield must be removed.
Drip Shield Removal: Refer to Figure 1, remove the two (2) screws
that secure the drip shield support brackets to the condensate
collectors (one screw per side). Remove the two (2) screws that
secure the drip shield to the drain pan. The drip shield and drip
shield brackets may now be removed.
The bottom left drain connection is the primary drain for this application and condensate drain line must be attached to this drain
connection. The top connection of the three drain connections on
the drain pan must remain plugged for this application. The bottom right drain connection is for the secondary drain line (if used).
6.2 Horizontal Left Installation
No field modifications are permissible for this application.
The bottom right drain connection is the primary drain for this
application and condensate drain line must be attached to this drain
connection. The top connection of the three drain connections on

the drain pan must remain plugged for this application. The bottom left drain connection is for the secondary drain line (if used).
Use condensate management kit if equipment is installed in high humidity condition (for example: 70% or higher).
6.3 Downflow/Horizontal Right Installation
IMPORTANT NOTE: In the downflow application, to prevent coil pan “sweating”, a downflow kit (DFK) is available through your
local Goodman distributor. The DFK is not supplied with the air handler and is required by Goodman on all downflow installations.
See Table 2 for the correct DFK and follow the instructions provided for installation.
Refer to Figure 6 and 7 for the location of the components referenced in the following steps.
1. Before inverting the air handler, remove blower access panel and coil access panel. The coil access panel and tubing panel may
remain screwed together during this procedure. Remove and retain the seven (7) screws securing the coil access panel to the
cabinet and the six (6) screws securing the blower access panel
to the cabinet.
2. Slide the coil assembly out using the drain pan to pull the assembly from the cabinet.
NOTE: DO NOT USE MANIFOLDS OR FLOWRATOR TO PULL THE
COIL ASSEMBLY OUT. FAILURE TO DO SO MAY RESULT IN BRAZE
JOINT DAMAGE AND LEAKS.

7.1 Tubing Size
For the correct tubing size, follow the specification for the condenser/heat pump.
7.2 Tubing Preparation
All cut ends are to be round, burr free, and clean. Failure to follow this practice increases the chances for refrigerant leaks. The
suction line is spun closed and requires tubing cutters to remove the closed end.
NOTE: To prevent possible damage to the tubing joints, do not
handle coil assembly with manifold or flowrator tubes. Always
use clean gloves when handling coil assemblies.

7.4 Thermal Expansion Valve System Adjustment
Run the system at Cooling for 10 minutes until refrigerant pressures
stabilize. Use the followung guidelines and methods to check unit
operation and ensure that the refrigerant charge is within limits.
Charge the unit on low stage.
1. Purge gauge lines. Connect service gauge manifold to base-valve service
ports.
2. Temporarily install a thermometer on the liquid line at the liquid line service valve and 4-6’’ from the compressor on the suction line. Ensure the
thermometer makes adequate contact and is insulated for best possible
readings. Use liquid line temperatice to determine subcooling and vapor
temperature to determine superheat.
3. Check subcooling and superheat. Systems with TXV application should
have a subcooling of 5 to 7°F and superheat of 7 to 9°F
a. If subcooling and superheat are low, adjust TXV to 7 to 9°F, and then check subcooling.

8 Condensate Drain Lines
The coil drain pan has a primary and a secondary drain with 3/4" NPT female connections. The connectors required are 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 of approximately 3/8” to 1/2” (3-5 turns) should be expected at this torque.
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 all drain lines a minimum of 1/4" per foot to provide free drainage. Provide required
support to the drain line to prevent bowing. If the secondary drain
line is required, run the line separately from the primary drain and
If secondary drain is not installed, the secondary
access must be plugged.
end it where condensate discharge can be easily seen.
NOTE: Water coming from secondary line means the coil primary
drain is plugged and needs immediate attention.
Insulate drain lines located inside the building or above a finished living space to
prevent sweating. Install a condensate trap to ensure proper drainage.
NOTE: When units are installed above ceilings, or in other locations where
damage from condensate overflow may occur, it is MANDATORY to install a field
fabricated auxiliary drain pan under the coil cabinet enclosure.
The installation must include a “P” style trap that is located as close as is practical to the evaporator coil. See Figure 12 for details of a typical condensate line
“P” trap.
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.
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. Goodman® 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.
Use of a condensate removal pump is permitted when necessary. This condensate pump should have provisions for shutting off the
control voltage should a blocked drain occur. A trap must be installed between the unit and the condensate pump.

IMPORTANT NOTE: The evaporator coil is fabricated with oils that may dissolve styrofoam and certain types of plastics. Therefore, a
removal pump or float switch must not contain any of these materials.
Tip: Priming the “P” trap may avoid improper draining at the initial installation and at the beginning of the cooling season.
9 Ductwork
This air handler is designed for a complete supply and return ductwork system.
To ensure correct system performance, the ductwork is to be sized to accommodate 350-450 CFM per ton of cooling with the static
pressure not to exceed 0.5" in w.c. Refer to ACCA Manual D, Manual S and Manual RS for information on duct sizing and application.
Flame retardant ductwork is to be used and sealed to the unit in a manner that will prevent leakage.
NOTE: A downflow application with electric heat must have an L-shaped sheet metal supply duct without any outlets or registers
located directly below the heater.
9.1 Return Ductwork
DO NOT LOCATE THE RETURN DUCTWORK IN AN AREA THAT CAN INTRODUCE TOXIC, OR OBJECTIONABLE FUMES/ODORS INTO
THE DUCTWORK. The return ductwork is to be connected to the air handler bottom (upflow configuration).
10 Return Air Filters
Each installation must include a return air filter. This filtering may be performed at the air handler using the factory filter rails or
externally such as a return air filter grille. When using the factory filter rails, a nominal 16x20x1”, 20x20x1” or 24x20x1” (actual
9
dimension must be less than 23-½”x20”) filter can be installed on a B, C and D cabinet respectively (the cabinet size is the seventh letter
of the model number).
11 Electric Heat
Refer to the installation manual provided with the electric heat kit
for the correct installation procedure. All electric heat must be
field installed. If installing this option, the ONLY heat kits that are
permitted to be used are the HKS series. Refer to the air handler
unit’s Serial and Rating plate or the HKS specification sheets to
determine the heat kits compatible with a given air handler. No
other accessory heat kit besides the HKS series may be installed in these air handlers.
The heating mode temperature rise is dependent upon the system airflow, the supply voltage, and the heat kit size (kW) selected. Use
data provided in Tables 3, 4 and 5 to determine the temperature rise (°F).
NOTE: For installations not indicated above the following formula is to be used:
TR = (kW x 3412) x (Voltage Correction) / (1.08 x CFM)
Where: TR = Temperature Rise
kW = Heater Kit Actual kW
3412 = Btu per kW
VC* = .96 (230 Supply Volts)
= .92 (220 Supply Volts)
= .87 (208 Supply Volts)
1.08 = Constant
CFM = Measured Airflow
Do not operate this product without all the ductwork
attached.
VC* (Voltage Correction)
NOTE: The Temperature Rise Tables can also be used to estimate the air handler airflow delivery. When using these tables for this
purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions. Insert two thermometers,
one in the return air and one in the supply air. The temperature rise is the supply air temperature minus the return air temperature.
Using the temperature rise calculated, CFM can be estimated from the TR formula above. See Spec Sheets and/or Service Manual for
more information.
12 Electrical and Control Wiring
IMPORTANT: All routing of electrical wiring must be made through provided electrical knockouts. Do not cut, puncture or alter the
cabinet for electrical wiring.
