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 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.

4
5.4 Clearances
The unit clearance from a combustible surface may be 0". However, service clearance must take precedence. A mini-
mum 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 ARUF**14**, ARPT**14**, ASPT**14** and ASUF**14** product lines 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 sec-
ondary drain line (if used).

6.3 Downflow/Horizontal Right Installation
IMPORTANT NOTE: In the downflow application, to pre-
vent coil pan “sweating”, a downflow kit (DFK) is available
through your local distributor. The DFK is not supplied with
the air handler and is required by the manufacturer on all
downflowinstallations.SeeTable1for 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.

7 Refrigerant Lines
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
instructionsprovidedwith the condenser. If the unit is located
inanunconditioned 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. 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 flowrator tubes. Always use clean gloves when handling coil assemblies.

This product is factory-shipped with R410A and dry
nitrogen mixture gas under pressure. Use appropriate
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.
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

7.3 Special Instructions
Units without a factory installed TXV come equipped with a flowrator piston for refrigerant expansion. For most instal-
lations with matching applications, no change to the flowrator piston is required. However, in mix-matched applica-
tions, 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.
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 appropri-
ate 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.
6. Remove the tailpiece clamped to the exterior of the cabinet or in
the literature kit packet and slide the 13/16 nut into place.
7. Braze tailpiece to the line set liquid tube and braze suction line
connection.Quenchallbrazed joints with a damp rag upon comple-
tion 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.

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 indi-
cates possible leak.
3. Replace the refrigerant tubing panel.
4. Remove the spin closure on both the liquid and suction tubes using a tubing cutter.
5. Insert liquid line set into liquid tube expansion and slide grommet about 18" away from braze joint.
6. Insert suction line set into suction tube expansion and slide insulation and grommet about 18" away from braze joint.
7. Braze joints. Quench all brazed joints with water or a wet rag upon completion of brazing.

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 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
locationswheredamagefromcondensateoverflowmayoccur,
itisMANDATORYtoinstallafieldfabricatedauxiliarydrainpan
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 conden-
sate 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 leak-
age. 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 shut-
ting 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.

TIONABLE 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 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 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) / (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 Airflow
*VC (Voltage Correction)
NOTE: TheTemperatureRise Tables can also be used toestimate
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
isthesupplyair 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.

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.
12.1 Building Electrical Service Inspection
This unit is designed for single-phase electrical supply only. DO NOT OPERATE ON A THREE-PHASE POWER
SUPPLY. Measure the power supply to the unit. The
supply voltage must be measured and be in agree-
ment with the unit nameplate power requirements and
within the range shown.
12.2 Wire Sizing
Wire size is important to the operation of your equip-
ment. Use the following check list when selecting the
appropriate wire size for your unit.
•Wire used must carry the Minimum Circuit Ampac-
ity (MCA) listed on the unit’s Series and Rating
Plate.
• Refer to the NEC (USA) or CSA (Canada) for wire siz-
ing. The unit MCA for the air handler and the optional
electric heat kit can be found on the unit Series and
Rating Plate.
•Wire must be sized to allow no more than a 2%
voltage drop from the building breaker/fuse panel
to the unit.
• Wires with different insulation temperature rating have
varying ampacities - be sure to check the temperature
rating used.
Refer to the latest edition of the National Electric Code
or in Canada the Canadian Electric Code when deter-
mining the correct wire size.
12.3 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 provides the maximum overcurrent device permissible.
NOTE: Fuses or circuit breakers are to be sized larger than the equipment MCA but not to exceed the MOP.

FIRE HAZARD!
To avoid the risk of property damage, personal injury
or fire, use only copper conductors.
HIGH VOLTAGE!
Failure to do so may cause property damage,
personal injury or death.
Disconnect ALL power before servicing.
Multiple power sources may be present.
HIGH VOLTAGE!
To avoid property damage, personal injury or death
due to electrical shock, this unit MUST have an
electrical ground. The
electrical ground circuit may consist of an
appropriately sized electrical wire connecting the
ground lug in the unit control box to the building
electrical service panel.
Other methods of grounding are permitted if performed
in accordance with the National Electric Code
(NEC)/American National Standards Institute
(ANSI)/National Fire Protection Association (NFPA) 70
and local/state codes. In Canada, electrical grounding
is to be in accordance with the CanadianElectric Code
(CSA) C22.1.

12.4 Electrical Connections – Supply Voltage
IMPORTANT NOTE: USE COPPER CONDUCTORS ONLY.
Knockouts are provided on the air handler top panel and sides of the
cabinettoallowfortheentryofthe supply voltage conductors, asshown
in Figure 13. If the knockouts on the cabinet sides are used for electri-
cal 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. Some codes/municipalities require the supply
wire to be enclosed in conduit. Consult your local codes.
12.4.1 Air Handler Only (Non-Heat Kit Models)
The building supply connects to the stripped black and red wires con-
tained in the air handler electrical compartment cavity. A ground screw
is also contained in this area. Attach the Supply wires to the air han-
dler conductors 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 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.
12.5 Low Voltage Connections
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 100 feet. Low voltage wiring must be connected through the top of the cabinet or either side. See the “Thermo-
stat 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 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 multi-speed 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.

13 Achieving 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.
14 Start-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.
• 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.
15 Regular Maintenance
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.
HIGH VOLTAGE!
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.

Air Handler Low Voltage Connections
The following composite wiring diagrams detail various configurations 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 configurations can be applied
with convenient connections to outdoor thermostat applications.
The following sections are detailed:
• Single-StageCooling
• Heat Pump
Each diagram details the connections between room thermostat 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 configura-
tion, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will result in the
programmed fixed 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.
An equivalent thermostat can be used in place of the manufacturer’s thermostat part number.
NOTE:Somemodelsfeature lowvoltagewiresanddonotincludeaterminal block.Forthoseapplicationsuse thecorresponding
colored wires.
NOTES:
1) OUTDOOR THERMOSTAT (OT-1) SHOULD BE THE
FIRST TO CLOSE AND THE LAST TO OPEN.
2) JUMPER W1 AND W2 TOGETHER IF OT-2 IS NOT
USED.
3) REMOVE WIRE WHEN USING OUTDOOR THERMO-
STAT.
