5 Pre-Installation Considerations
5.1 Preparation
Keep this document with the unit. Carefully read all in-
structions for the installation prior to installing product.
Make sure each step or procedure is understood and
any special considerations are taken into account be-
fore starting installation. Assemble all tools, hardware
and supplies needed to complete the installation. Some
items may need to be purchased locally. Make sure ev-
erything 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-Con-
ditioning, Heating, and Refrigeration Institute (AHRI)
listed. NOTE: Installation of unmatched systems is not
permitted.
5.3 Interconnecting Tubing
Give special consideration to minimize the length of re-
frigerant tubing when installing air handlers. Refer to Re-
mote 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 disconnect-
ing 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 nal
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 conden-
sate line (1/4” per foot) is allowed.
5.5 Horizontal Applications
If installed above a nished 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 instal-
lation only.

The ARUF**14** and ASPT**14** product lines may be in-
stalled in one of the upow, downow, horizontal left or hori-
zontal right orientations as shown in Figures 2, 3, 4 and 5. The
unit may be installed in upow or horizontal left orientation as
shipped (refer to specic sections for more information).
No eld modications are mandatory. However, to obtain
maximum eciency, the horizontal drip shield, side drain
pan and drain pan extension can be removed.
Side Drain Pan and Extension Removal: Refer to Figure
1, remove the two (2) screws that secure the drip shield sup-
port brackets to the condensate collectors (front and back).
Unsnap the side drain pan from the bottom drain pan using
a screw driver or any small lever. The side drain pan, drip
shield brackets and the drain pan extension may now be re-
moved. From Figure 1, drain port labeled (A) is the primary
drain for this application and condensate drain line must be
attached to this drain port. Drain port (a) is for the second-
ary drain line (if used). If the side drain pan is removed, the
drain port opening in the access panel must be covered by
the accessory drain port plug (DPK1) as shown in gure 1.1.

WARNING
THIS PRODUCT IS FACTORY-SHIPPED WITH R410A AND DRY
NITROGEN MIXTURE GAS UNDER PRESSURE. USE APPRO-
PRIATE SERVICE TOOLS AND FOLLOW THESE INSTRUCTIONS
TO PREVENT INJURY.
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 locat-
ed in an unconditioned area with high ambient temperature
and/or high humidity, the air handler may be subject to nui-
sance sweating of the air handler cabinet. On these installa-
tions, a wrap of 2” berglass insulation with a vapor barrier
is recommended.
7.1 Tubing Size
For the correct tubing size, follow the specication for
the condenser/heat pump.
7.2 Tubing Preparation
All cut ends are to be round, burr free, and clean. Fail-
ure to follow this practice increases the chances for re-
frigerant leaks. The suction line is spun closed and re-
quires tubing cutters to remove the closed end.
NOTE: To prevent possible damage to the tubing joints, do
not handle coil assembly with manifold or owrator tubes.
Always use clean gloves when handling coil assemblies.
7.3 Special Instructions
Units without a factory installed TXV come equipped with
a owrator piston for refrigerant expansion. For most in-
stallations with matching applications, no change to the
owrator piston is required. However, in mix-matched
applications, a owrator piston change may be required.
See the piston kit chart (provided in the literature pack-
et) or consult your local distributor for details regarding
mix-matched owrator piston sizing. If the mix-match
application requires a dierent owrator piston size,
change the owrator piston in the owrator body on the
indoor coil before installing the coil and use the proce-
dure in section 7.4.
NOTE: The use of a heat shield is strongly recommend-
ed when brazing to avoid burning the serial plate or the
nish 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.
WARNING
A QUENCHING CLOTH IS STRONGLY RECOMMENDED TO PRE-
VENT SCORCHING OR MARRING OF THE EQUIPMENT FINISH
WHEN BRAZING CLOSE TO THE PAINTED SURFACES. USE
BRAZING ALLOY OF 5% MINIMUM SILVER CONTENT.
CAUTION
APPLYING TOO MUCH HEAT TO ANY TUBE CAN MELT THE
TUBE. TORCH HEAT REQUIRED TO BRAZE TUBES OF VARI-
OUS 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.

See section 7.7 for detailed information on adjusting the
thermal expansion valve.
7.7 Thermal Expansion Valve System Adjustment
Run the system at Cooling for 10 minutes until refrigerant
pressures stabilize. Use the following guidelines and meth-
ods 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 compres-
sor on the suction line. Ensure the thermometer makes
adequate contact and is insulated for best possible
readings. Use liquid line temperature to determine sub-
cooling and vapor temperature to determine superheat.
3. Check subcooling and superheat. Systems with TXV
application should have a subcooling of 7 to 9ºF and
superheat of 7 to 9 ºF.
a. If subcooling and superheat are low, adjust TXV to
7 to 9 ºF superheat, then check subcooling.
NOTE: To adjust superheat, turn the valve stem
clockwise to increase and counter clockwise to de-
crease.
b. If subcooling is low and superheat is high, add
charge to raise subcooling to 7 to 9ºF then check
superheat.
c. If subcooling and superheat are high, adjust TXV
valve to 7 to 9 ºF superheat, 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 pre-
vent 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 n-
ished space, it may be necessary to insulate the con-
densate drain line located inside the building. Use Ar-
maex® or similar material.
A secondary condensate drain connection has been provid-
ed for areas where the building codes require it. Pitch all
drain lines a minimum of 1/4” per foot to provide free drain-
age. Provide required support to the drain line to prevent
bowing.
If the secondary drain line is required, run the line sepa-
rately 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.
CAUTION
IF SECONDARY DRAIN IS NOT INSTALLED, THE SECONDARY
ACCESS MUST BE PLUGGED.
Insulate drain lines located inside the building or above a n-
ished 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 overow may oc-
cur, it is MANDATORY to install a eld 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: Units operating in high static pressure applications
may require a deeper eld constructed “P” style trap than
is shown in Figure 12 to allow proper drainage and prevent
condensate overow.

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.
Use of a condensate removal pump is permitted when nec-
essary. This condensate pump should have provisions for
shutting o the control voltage should a blocked drain occur.
A trap must be installed between the unit and the conden-
sate pump.
IMPORTANT NOTE: The evaporator coil is fabricated with
oils that may dissolve styrofoam and certain types of plas-
tics. Therefore, a removal pump or oat switch must not con-
tain 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.
CAUTION
DO NOT OPERATE THIS PRODUCT WITHOUT ALL THE
DUCTWORK ATTACHED.
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 downow application with electric heat must have
an L-shaped sheet metal supply duct without any outlets or
registers located directly below the heater.
11
9.1 Return Ductwork
DO NOT LOCATE THE RETURN DUCTWORK IN AN
AREA THAT CAN INTRODUCE TOXIC, OR OBJEC-
TIONABLE FUMES/ODORS INTO THE DUCTWORK.
The return ductwork is to be connected to the air handler
bottom (upow conguration).
10 Return Air Filters
Each installation must include a return air lter. This ltering
may be performed at the air handler using the factory lter
rails or externally such as a return air lter grille. When us-
ing the factory lter rails, a nominal 16x20x1”, 20x20x1” or
24x20x1” (actual dimension must be less than 23-½”x20”)
lter 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 eld 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 specication sheets to determine the heat kits compat-
ible with a given air handler. No other accessory heat kit be-
sides the HKS series may be installed in these air handlers.
The heating mode temperature rise is dependent upon the
system airow, the supply voltage, and the heat kit size (kW)
selected. Use data provided in Tables 5, 6, AND 7 to deter-
mine the temperature rise (°F).
NOTE: For installations not indicated above the following
formula is to be used:
TR = (kW x 3412) x (Voltage Correction) / (1.08XCFM)
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 Airow
*VC (Voltage Correction)
NOTE: The Temperature Rise Tables can also be used to
estimate the air handler airow 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 tempera-
ture minus the room air temperature. Using the temperature
rise calculated, CFM can be estimated from the TR formula
above. See Service Manual for more information.

12.4.1 Air Handler Only (Non-Heat Kit Models)
The building supply connects to the stripped black and
red wires contained in the air handler electrical com-
partment cavity. A ground screw is also contained in this
area. Attach the Supply wires to the air handler conduc-
tors as shown in the unit wiring diagram using appropri-
ately sized solderless connectors or other NEC or CEC
approved means.
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 soft plastic cover on the upper ac-
cess panel and can be removed to allow the heater kit
circuit breaker to be installed. The circuit breakers have
lugs for power supply connection. See the HKS Installa-
tion Instructions for further details.
12.5 Low Voltage Connections
Several combinations of low voltage schemes are possi-
ble, depending on the presence of a heat kit and wheth-
er 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 100 feet. Low voltage wir-
ing 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 multi-
stage heating thermostat or the addition of an outdoor
thermostat as shown in wiring schematics on page 19.
Follow the thermostat manufacturer’s instructions for in-
stallation.
12.6 Speed Tap Adjustment
ARUF**14** air handlers have multi-speed PSC mo-
tors. The color of the wire coming from the motor to the
“COM” terminal on the control board denes 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.
15
ASPT**14** air handlers feature energy ecient 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 de-
sired speed tap on the terminal block. The ASPT blower
motor speeds are programmed to deliver adequate air-
ow at rated external static pressure and with 60 sec-
ond o time delay. For details, refer to the specication
sheet applicable to your model.
NOTE: In some models, not all speed taps are allowable
for certain electric heat applications. Refer to Table 6 for
minimum speed.
13 Achieving 1.4% 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 blower access panel, blower access
and coil access panels, and between the coil access and
lter access panels. Ensure upon installation, that the plastic
breaker cover is sitting ush on the blower access panel and
all access panels are ush with each other and the cabinet.
With these requirements satised, the unit achieves less
than 1.4% airow leakage when tested in accordance with
ASHRAE Standard 193.

17 Air Handler Low Voltage Connections
The following composite wiring diagrams detail various con-
gurations in which the air handlers can be used. Examples
include single-stage cooling and heat pump with single or
two-stage electric heating. All these congurations can be
applied with convenient connections to outdoor thermostat
applications.
The following sections are detailed:
• Single-Stage Cooling
• Heat Pump
Each diagram details the connections between room ther-
mostat and the air handlers, and the connections between
the air handlers and the Condensing Unit (or Heat Pump)
with optional connections to Outdoor Thermostats. For each
conguration, refer to the explanation of the proper jumper(s)
to remove for the corresponding blower speed that will result
in the programmed xed speed ECM 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.
Any equivalent thermostat can be used in place of the man-
ufacturer’s thermostat part number.

REPLACE OR CLEAN FILTER
IMPORTANT NOTE: Never operate unit without a lter in-
stalled as dust and lint will build up on internal parts resulting
in loss of eciency, equipment damage and possible re.
An indoor air lter must be used with your comfort system.
A properly maintained lter will keep the indoor coil of your
comfort system clean. A dirty coil could cause poor opera-
tion and/or severe equipment damage.
Your air lter or lters could be located in your furnace, in a
blower unit, or in “lter grilles” in your ceiling or walls. The
installer of your air conditioner or heat pump can tell you
where your lter(s) are, and how to clean or replace them.
Check your lter(s) at least once a month. When they are
dirty, replace or clean as required. Disposable type lters
should be replaced. Reusable type lters may be cleaned.
You may want to ask your dealer about high eciency l-
ters. High eciency lters are available in both electronic
and non-electronic types. These lters can do a better job of
catching small airborne particles.
MOTORS
Indoor and outdoor fan motors are permanently lubricated
and do not require additional oiling.

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 ush
the coil with water. This cleaning practice remains as the
recommended cleaning method for both copper tube and
aluminum tube residential evaporator coils.
It has been determined that many coil cleaners and drain
pan tablets contain corrosive chemicals that can be harmful
to aluminum tube and n evaporator coils. Even a one-time
application of these corrosive chemicals can cause prema-
ture aluminum evaporator coil failure. Any cleaners that con-
tain corrosive chemicals including, but not limited to, chlo-
rine and hydroxides, should not be used.
AIR HANDLER
AIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
An alternate cleaning method is to use one of the products
listed in TP-109* 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 also available on the
web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemi-
cal cleaners.
CAUTION
TO AVOID THE RISK OF EQUIPMENT DAMAGE OR FIRE, IN-
STALL THE SAME AMPERAGE BREAKER OR FUSE AS YOU
ARE REPLACING. IF THE CIRCUIT BREAKER OR DUSE SHOULD
OPEN AGAIN WITHIN THIRTY DAYS, CONTACT A QUALIFIED
SERVICER TO CORRECT THE PROBLEM.
IF YOU REPEATEDLY RESET THE BREAKER OR REPLACE THE
FUSE WITHOUT HAVING THE PROBLEM CORRECTED, YOU RUN
THE RISK OF SEVERE EQUIPMENT DAMAGE.
BEFORE YOU CALL YOUR SERVICER
• Check the thermostat to conrm that it is properly set.
• Wait 15 minutes. Some devices in the outdoor unit or
in programmable thermostats will prevent compres-
sor operation for awhile, and then reset automatical-
ly. Also, some power companies will install devices
which shut o air conditioners for several minutes on
hot days. If you wait several minutes, the unit may
begin operation on its own.
• Check the electrical panel for tripped circuit breakers
or failed fuses. Reset the circuit breakers or replace
fuses as necessary.
• Check the disconnect switch near the indoor furnace
or blower to conrm that it is closed.
• Check for obstructions on the outdoor unit. Conrm
that it has not been covered on the sides or the top.
Remove any obstruction that can be safely removed.
If the unit is covered with dirt or debris, call a quali-
ed servicer to clean it.
• Check for blockage of the indoor air inlets and out-
lets. Conrm that they are open and have not been
blocked by objects (rugs, curtains or furniture).
• Check the lter. If it is dirty, clean or replace it.
• Listen for any unusual noise(s), other than normal
operating noise, that might be coming from the out-
door unit. If you hear unusual noise(s) coming from
the unit, call a qualied servicer.
