Maximum Overcurrent Protection (MOP)
Every installation must include an NEC (USA) or CEC
(Canada) approved overcurrent protection device. Also,
check with local or state codes for any special regional requirements.
Protection can be in the form of fusing or HACR style circuit
breakers. The Series and Rating Plate can be used as a
guide for selecting the MAXIMUM overcurrent device.
Refrigerant Lines
This product is factory-shipped under pressure. Follow
these instructions to prevent injury.
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.
NOTE: Fuses or circuit breakers are to be sized larger
than the equipment MCA but not to exceed the MOP.
Electrical Connections – Supply Voltage
USE COPPER CONDUCTORS ONLY.
A knockout is provided on the air handler top panel or side to
allow for the entry of the supply voltage conductors. If the
knockouts on the cabinet sides are used for electrical conduit, an adapter ring must be used in order to meet UL1995
safety requirements. An NEC or CEC approved strain relief
is to be used at this entry point. The wire is to be sized in
accordance with the “Electrical Wire and MOP” section of
this manual. Some areas require the supply wire to be enclosed in conduit. Consult your local codes.
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 pipe cutters to remove the closed end.
Post Brazing
Quench all welded joints with water or a wet rag.
Piping Size
For the correct tubing size, follow the specification
for the condenser/heat pump.
Air Handler Only (Non-Heat Kit Models)
The building supply connects to the stripped black and red
wires contained in the air handler electrical compartment cavity. A ground screw is also contained in this area. Attach the
supply wires to the air handler conductors as shown in the
unit wiring diagram using appropriately sized solderless connectors or other NEC or CEC approved means.
CAUTION
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.
Air Handler With Non-Circuit Breaker Heat Kits
A terminal block is provided with the HKR kit to attach the
power supply and air handler connections. Follow the HKR
Installation Manual and wiring diagram for complete wiring
details.
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 piston is required.
However, in mix-matched applications, a flowrator piston
change may be required. See the Goodman® piston kit chart
or consult your local distributor for details regarding mixmatched piston sizing. If the mix-match application requires
a different piston size, change the piston in the flowrator on
the indoor coil before installing the coil and follow the procedure shown below.
Air Handler With Heat Kits Containing a Circuit Breaker
HKR models with a “C” suffix contain a circuit breaker(s).
The air handler has a plastic cover on the access panel that
will require either one or both sections to be removed to allow the heat kit circuit breaker(s) to be installed. See the
HKR Installation Instructions for further details. The air handler wires and supply wires are installed directly onto the HKR
circuit breaker(s) as shown in the HKR Installation Manual
and wiring diagram.
IMPORTANT NOTE: Torch heat required to braze tubes of
various sizes is proportional to the size of the tube. Tubes of
smaller size require less heat to bring the tube to brazing
temperature before adding brazing alloy. Applying too much
heat to any tube can melt the tube. Service personnel must
use the appropriate heat level for the size of the tube being
brazed.
NOTE: The use of a heat shield when brazing is recommended
to avoid burning the serial plate or the finish on the unit. Heat
trap or wet rags should be used to protect heat sensitive
components such as service valves and TXV valves.
Low Voltage Connections
Several combinations of low voltage schemes are available,
depending on the presence of a heat kit and whether the
heat kit is single-stage or multi-staging. The low voltage connections are determined by whether the outdoor unit is a condenser or heat pump. The 24V-control voltage connects the
air handler to the room thermostat and condenser. Low voltage wiring is to be copper conductors. A minimum of 18AWG
must be used for installations up to 50’ and 16AWG for installations over 50’. Low voltage wiring can be connected
through the top of the cabinet or either side. See the “Thermostat Wiring” section of this manual for typical low voltage
wiring connections.

7. Install the plastic plug removed in step 5 to the right
side lower access panel and the oval shaped rubber
gasket to the lower left access panel.
NOTE: When converted to downflow position, the coil may
protrude above the cabinet on some models.
8. Reinstall the evaporator coil with the horizontal panel
on the left side. Note: Push the assembly completely to
the rear to ensure the engagement of the upflow pan
with the rear channel bracket.
Horizontal Conversion
Dedicated Downflow models are not suitable for horizontal
application and must not be used for this type of installation.
The only field modification required for conversion to “Horizontal Right-Hand” is the removal of the plastic knockouts in
the horizontal panel drain connections. To prevent the horizontal drain pan from sweating in high humidity applications,
it is recommended that a DPIH insulation accessory kit be
used. NOTE: The DPIH insulation kit is not supplied with this
product and should be purchased separately. See Table 8
for the correct DPIH kit.

9. Install the “J” bracket (removed in step 2) to support the
upflow pan to the tie channel.
10. Attach all panels and the metering device.
Condensate Removal
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, CPVC or metal
pipe and should be hand tightened to a torque of approximately 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. Use the female (3/4
fpt) threaded fitting that protrudes outside of the enclosure
for external connections.
Table 8
1. Ensure drain pan hole is NOT obstructed.
The following describes converting to “Horizontal Left-Hand”.
Conversion to downflow MUST be performed in an area that
allows access to all sides prior to placing the air handler in its
2. To prevent potential sweating and dripping on to finished
space, it may be necessary to insulate the condensate
8
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 located inside the building to prevent sweating. Install a
condensate trap to ensure proper drainage. If the secondary
drain 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.
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.
When coils 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. Drain lines from the auxiliary
pan must be installed and terminated so that the homeowner
can see water discharges.
ACHIEVING 2% LOW LEAKAGE RATE
CAUTION
Ensure that the Neoprene gasket with PSA remains intact on
all surfaces that the access panels are secured to. These
surfaces are the entire length of the wrapper and areas between the upper tie plate, upper and lower access panels.
Be sure that upper access panel breaker insert gasket is intact and also flowrator gasket is installed on the lower access panel. An additional drain hole cover is required.
If secondary drain is not installed, the secondary
access must be plugged.
The installation must include a “P” style trap that is located
as close as is practical to the evaporator coil. See Figure 7
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.
ATUF/ARUF/ARPF/ADPF MOTOR
(Motor Speed Adjustment)
The motors in all ATUF, ARUF, ARPF and ADPF motors are
multi-speed PSC motors. The color of the wire coming from
the motor to the “COM” terminal on the control board defines
in which speed the motor will operate. The black wire represents high speed, the red wire represents low speed, and
the blue wire (select models only) represents medium speed.
To change speeds, remove the wire attached to the “COM”
terminal on the control board, and swap it with the wire (on
terminal “M1” or “M2”) with the color that will give the desired
speed.
NOTE: In some models, not all speed taps are allowable for
certain electric heat applications. Refer to air handler Series
and Ratings plate for minimum speed.

Use of a condensate removal pump is permitted when necessary. This condensate pump should have provisions for

A trap must be installed between the unit and the condensate pump.
IMPORTANT NOTE: The evaporator coil is coated with oils
that may dissolve styrofoam and certain types of plastics.

ASPF THERMOSTAT CONNECTIONS
The following composite wiring diagrams detail various configurations in which the ASPF air handlers can be used. Examples include single-stage cooling and heat pump with single or two-stage electric heating. All these configurations can be
applied with convenient connections to outdoor thermostat applications.
The following sections will be detailed:
•
Single-Stage Cooling (GMC Thermostat Part #CHT18-60 or equivalent.)
•
Heat Pump (GMC Thermostat Part #18-60 or equivalent)
Each diagram details the connections between room thermostat and ASPF air handlers, and the connections between the
ASPF air handlers and the Condensing Unit (or Heat Pump) with optional connections to Outdoor Thermostats. For each
configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will result
in the programmed ECM™ motor.
IMPORTANT: WHEN MATCHING THE ASPF AIR HANDLERS TO A SINGLE SPEED COOLING OR HEAT PUMP UNIT, REMEMBER TO CONNECT “Y” FROM THE THERMOSTAT TO
THE “Y2” ON THE LOW VOLTAGE TERMINAL BOARD.
An equivalent thermostat can be used in place of the Goodman thermostat part number. The GMC thermostats that listed
