Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas
Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions. If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area. Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.
CO can cause serious illness including permanent brain damage or death.

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.
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 and will void the product 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 installa-
tion only.

7Refrigerant Lines
This product is factory-shipped with R410A and dry
nitrogen mixture gas under pressu re. Use appr opria te
service tools and follow these instructions to prevent
injury .
A quenching cloth is strongly recommended to prevent
scorching or marring of the equipment finish when
brazing close to the painted surfaces. Use brazing
alloy of 5% minimum silver content.
NOTE: Refrigerant tubing must be routed to allow adequate
access for servicing and maintenance of the unit.
Do not install the air handler in a location that violates the
instructions provided with the condenser. If the unit is located
in an unconditioned area with high ambient temperature and/
or high humidity, the air handler may be subject to nuisance
sweating of the casing. On these installations, a wrap of 2"
fiberglass insulation with a vapor barrier is recommended.
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.
ACCESS PANEL CONFIGURATION FOR DOWNFLOW
OR HORIZONTAL RIGHT

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.
CAUTION
Applying too much heat to any tube can melt the tube. T orch
heat required to braze tubes of various sizes mu st be
proportional to the s ize of t h e tub e . S er v ice p e rso n n el m u st
use the appropriate heat level for the size of the tube being
brazed.
7.3 Special Instructions
Units without a factory installed TXV come equipped
with a flowrator piston for refrigerant expansion. 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 piston kit chart (provided in
the literature packet) or consult your local distributor
for details regarding mix-matched flowrator piston sizing. If the mix-match application requires a different
flowrator piston size, change the flowrator piston in the
flowrator body on the indoor coil before installing the
coil and use the procedure in section 8.4.
6
NOTE: The use of a heat shield is strongly recommended when brazing to avoid burning the serial plate
or the finish of the unit.
Heat trap or wet rags must be
used to protect heat sensitive components such as service valves and TXV valves sensing bulb.
7.4 Tubing Connections for Flowrator Model
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 been expelled, remove the nut and
discard the black or brass cap plastic seal.
3. Remove the flowrator piston to verify it is the correct
size for the outdoor unit being installed and then replace
the piston (changing size, if needed). See piston kit chart
in the literature kit for appropriate piston size.
4. Remove the spin closure on the suction line using a
tube cutter and deburr the tube.
5. Insert the suction line into the connection, slide the insulation and the rubber grommet at least 18" away from
the braze joint.
7. Braze tailpiece to the line set liquid tube and braze suction line connection. Quench all brazed joints with a
damp rag upon completion of brazing. Do not allow water
to enter the inside of the tubing.
8. AFTER THE TAILPIECE HAS COOLED, confirm position of the white Teflon® seal and hand tighten the 13/16
nut.
9. Torque the 13/16 nut to 7-25 ft-lbs. or tighten 1/6 turn.
Excessive torque can cause orifices to stick. Use the
proper torque settings when tightening orifices.
7.5 Tubing Connections for TXV Models
TXV models come with factory installed TXV with the
bulb pre-installed on the vapor tube.
1. Remove refrigerant tubing panel or coil (lower) access
panel.
2. Remove access valve fitting cap and depress the valve
stem in access fitting to release pressure. No pressure
indicates possible leak.

7. Braze joints. Quench all brazed joints with water or a
wet rag upon completion of brazing.
8Condensate 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.
7
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 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.
CAUTION
If secondary drain is not inst a lled, the seconda ry
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 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. 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.

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.
9Ductwork
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).
Do not operate this product without all the ductwork
attached.
10Return 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 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).
11Electric 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.
Figure 12
8
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 2, 3 and 4 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) x 1.08 / 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
*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 room air temperature. Using the temperature rise
calculated, CFM can be estimated from the TR formula above.
See Technical Manual and/or Service Manual for more
information.
11.1 No Electric Heat Installed
If no electric heat accessory kit is installed, a cover plate
must be installed over the opening for electric heat. This
cover plate kit is available from Goodman®, Amana® and
Daikin brand distributors.
IMPORTANT: All routing of electrical wiring must be made
through provided electrical knockouts. Do not cut, puncture
or alter the cabinet for electrical wiring.
12.1 Building Electrical Service Inspection

12.4.1 Air Handler Only (Non-Heat Kit Models)
The power supply connects to the stripped black and
red wires contained in the air handler electrical compartment. 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. A ground lug is also provided in the electrical compartment. The ground wire
from the power supply must be connected to this ground
lug.
12.4.2 Air Handler - Non-Circuit Breaker Heat Kits
A terminal block is provided with the HKS kit to attach
the power supply and air handler connections. Follow
the HKS Installation Manual and wiring diagram for
complete wiring details.
12.4.3 Air Handler With Circuit Breaker Heat Kit
The air handler has a plastic cover on the upper access panel that will require either one or both sections
to be removed to allow the heat kit circuit breaker(s) to
be installed. The circuit breakers have lugs for power
supply connection. See the HKS Installation Instructions for further details.
Several combinations of low voltage schemes are possible, depending on the presence of a heat kit and
whether the heat kit is single-stage or multi-stage,
whether the outdoor section is an air conditioner or heat
pump, and whether the outdoor section is single-stage
or two-stage. The 24V-control voltage connects the air
handler to the room thermostat and condenser. Low
voltage wiring must be copper conductors. A minimum
of 18AWG must be used for installations up to 50’ and
16AWG for installations over 50’. Low voltage wiring
must 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.
12.5.1 Thermostats
Second-stage heat can be accomplished by a multistage heating thermostat or the addition of an outdoor
thermostat as shown in wiring schematics on pages
14 and 15. Follow the thermostat manufacturer’s instructions for installation.
12.6 Speed Tap Adjustment
ARUF**14** and ARPT**14** air handlers have multispeed PSC motors. The color of the wire coming from
the motor to the “COM” terminal on the control board
defines at which speed the motor will operate. Black
wire is high speed, blue wire is medium speed and red
wire is low 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.
ASPT**14** and ASUF**14** air handlers feature energy efficient blower motors. The motors run at a constant torque with very low power consumption and are
energized by 24 VAC. Adjust the CFM by changing
the 24 VAC leads to the desired speed tap on the terminal block. The ASPT blower motor speeds are programmed to deliver adequate airflow at rated external
static pressure and with 60 second off time delay. For
details, refer to the specification sheet applicable to
your model.
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.

13Achieving 2% Low Leakage Rate
Ensure all the gaskets remain intact on all surfaces as shipped
with the unit. These surfaces are areas between the upper
tie plate and coil access panel, blower access and coil access panels, and between the coil access and filter access
panels. Ensure upon installation, that the plastic breaker cover
is sitting flush on the blower access panel and all access
panels are flush with each other and the cabinet. With these
requirements satisfied, the unit achieves less than 2% airflow leakage when tested in accordance with ASHRAE Standard 193.
14Start-Up Procedure
•Prior to start-up, ensure that all electrical wires are properly sized and all connections are properly tightened.
•All panels must be in place and secured. For Air Tight
application, gasket must be positioned at prescribed
locations to achieve 2% leakage.
•Tubing must be leak free.
•Condensate line must be trapped and pitched to allow
for drainage.
•Low voltage wiring is properly connected.

Disconnect ALL power before servicing or
installing this unit. Multiple power sources may
be present. Failure to do so may cause property
damage, personal injury or death.
The only item required to be maintained on a regular basis
by the user is the circulating air filter(s). Filter should be
cleaned or replaced regularly, typically once per month. A
certified service technician must perform all other services.
IMPORTANT NOTE: If thumb screws are used to access the
filter, ensure the washer installed on the screw behind the
access panel remains in place after re-installation.
•Auxiliary drain is installed when necessary and pitched
to allow for drainage.
•Unit is protected from vehicular or other physical damage.
•Return air is not obtained from, nor are there any return air duct joints that are unsealed in, areas where
there may be objectionable odors, flammable vapors
or products of combustion such as carbon monoxide
(CO), which may cause serious personal injury or death.
Notes: • Airflow data indicated is 230V without air filter in place.
• The chart is for information only. For satisfactory operation, external static pressure must not exceed value shown on rating plate. The shaded
area indicates ranges in excess of maximum design external static pressure.
• Use the CFM adjustment factors of 0.98 for horizontal left and 0.96 for horizontal right & downflow orientations.

ASPT/ASUF Thermostat Connections
The following composite wiring diagrams detail various configurations in which the ASPT/ASUF 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
•Heat Pump
Each diagram details the connections between room thermostat and ASPT air handlers, and the connections between
the ASPT 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 EEM™ motor.
IMPORTANT: WHEN MATCHING THE ASPT 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
manufacturer’s thermostat part number.

SPLIT SYSTEMS
AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer.
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a filter installed as dust
and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
An indoor air filter must be used with your comfort system. A properly
maintained filter will keep the indoor coil of your comfort system clean.
A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace, in a blower unit,
or in “filter grilles” in your ceiling or walls. The installer of your air conditioner or heat pump can tell you where your filter(s) are, and how to
clean or replace them.
Check your filter(s) at least once a month. When they are dirty, replace
or clean as required. Disposable type filters should be replaced. Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types.
These filters can do a better job of catching small airborne particles.
Compressor
The compressor motor is hermetically sealed and does not require additional oiling.
Motors
Indoor and outdoor fan motors are permanently lubricated and do not
require additional oiling.
Clean Outside Coil (Qualified Servicer Only)
Air must be able to flow through the outdoor unit of your comfort system.
Do not construct a fence near the unit or build a deck or patio over the
unit without first discussing your plans with your dealer or other qualified servicer. Restricted airflow could lead to poor operation and/or severe equipment damage.
Likewise, it is important to keep the outdoor coil clean. Dirt, leaves, or
debris could also restrict the airflow. If cleaning of the outdoor coil becomes necessary, hire a qualified servicer. Inexperienced people could
easily puncture the tubing in the coil. Even a small hole in the tubing
could eventually cause a large loss of refrigerant. Loss of refrigerant
can cause poor operation and/or severe equipment damage.
Do not use a condensing unit cover to “protect” the outdoor unit during
the winter, unless you first discuss it with your dealer. Any cover used
must include “breathable” fabric to avoid moisture buildup.
Before calling your servicer
•Check the thermostat to confirm that it is properly set.
•
Wait 15 minutes. Some devices in the outdoor unit or in programmable thermostats will prevent compressor operation for
awhile, and then reset automatically. Also, some power companies will install devices which shut off air conditioners for several
minutes on hot days. If you wait several minutes, the unit may
begin operation on its own.
